What is Reddit's opinion of 20 / 24-pin Power Supply Tester for ATX / SATA / HDD, Black?

From 3.5 billion Reddit comments

Assuming it was off when it got wet, it may be ok if you let it dry out completely. Of course modern power supplies are not really off, unless they are unplugged. Even then there is a small amount of current being supplied to the real time clock via the coin cell battery on the motherboard.

If it does not start up when dry it is possible it is just the power supply that is dead / blown fuse. The motherboard and cards / drives may still be fine.

The fuse in the power supply is not considered user serviceable so don't open it. If it is dead just toss it. They make ATX power supply testers and you can find them for cheap on Amazon.

-- EDIT -- Here is a power supply tester

I guess for 8 bucks, this. Lots of choices on amazon actually, just search power supply tester.

Still though even for that cheap at that rated wattage, I would just like to put it out there I wouldn't trust a used PSU from a stranger even if I have an implement to test it.

Have you tried testing GPU in another computer? If you can I'd recommend that to see if it really did fry the GPU. If it did, definitely bad psu. Swap that bad boy out. Also swap the Cable as it could have been fried as well.

If GPU is working fine in another computer, then it's going to be a bigger headache. Probably need to replace Mobo. Though this is unlikely the culprit. I'd almost bet money on bad PSU.

If you can, get a PSU tester. They're like $10-$20 and are very good for this kind of thing. Allows you to make sure it's PSU before hooking up a replacement part and frying it too.

Edit: Here's a cheap PSU tester. $11. Might be worth it to get it and test PSU first. Unless Corsair is willing to swap it out anyway. If they aren't, get that and test it. If you tell them you tested it with a PSU tester and it tests bad, they will not balk any about swapping it out.

Okay let's go back to basics and try to eliminate if it's a hardware fault. Have you tried powering it off at the wall for 30 seconds to a minute then powering it back on?

Have you tried another wall socket and power cable?

Does the PSU LED light up and fans spin when you turn it on at all? Do they power up then power off after 5 seconds or so?

Have you tried clearing out any dust from the fans?

Can you test another power supply from another computer or can you get hold of a power supply tester like the one below:

https://www.amazon.com.au/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S

Once the PSU is ruled out as working you'll need to test it powers up with individual components like CPU/heatsink/fan then RAM sticks individually etc.

Interesting, I might try this with a paperclip as suggested by someone else, and if it spins up I can test further with a multimeter. Just to be clear, I searched on amazon and found a PSU Tester for $7... is that the same as a multimeter? Here's the link to it:

Thanks!

You can get PSU testers on Amazon for like $12. I don't know what kinds of faults they do and don't detect, but maybe a worthwhile investment to test your wiring rather than using your system to test it. E.g.

The board controls power switching, so if it works reliably when you do the CMOS battery thing, it's almost certainly the board.

If you want to be sure, power supply testers are cheap.

Have you tried just leaving the CMOS battery out? Your board won't keep time and will lose all it's settings when it's off, but if the defaults work fine for your hardware and you're regularly unplugging it/plugging it back in, might be less headache to press a key to continue instead of removing/reinstalling the battery every time.

Could be a bad RAM stick, or a bad power supply.

If you can get inside the computer, and it has more than one stick of RAM, take one of them out but leave the other one in and try to turn it on. If it does the same thing, swap the RAM sticks and try again.

If it's a desktop, you could also try removing the GPU and anything else plugged into PCI and turn it on because it could be a short somewhere.

If it still doesn't work, you'd have to get a power supply tester, or just buy a new power supply and try it.

If none of the above works, it is possibly the motherboard.

You would have to test them in another computer that supports them. Should be pretty easy for the RAM and GPU, will probably be more difficult for the CPU. PSUs have testing tools https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S

I would test the power supply. If you already have a multimeter, you can use that. If not, you can purchase an inexpensive PSU tester https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S/ref=sr_1_2?ie=UTF8&qid=1515768177&sr=8-2&keywords=psu+tester

Could be your motherboard, and I'd suspect that before the power supply if the fans are moving. Try unplugging power to the machine, pressing the power button a few times while it's still unplugged, then plugging it back in and trying again.

Also power supply testers are cheap, no real reason not to have one handy.

id start with testing the power supply with a tester like this: https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S If the PSU checks out, check all your cabling and mobo manual to make sure any auxilary power plugs are being connected. If the fans arent coming on, and no power led's anywhere, then its either your power supply (less likely) or power cables not connected correctly (more likely). Also, seems simple, but check the wall outlet you are using to make sure you actually have power to the pc.

There's not really a way to test it. Usually though when a motherboard goes bad fans and the board will at least get power but not posting at all is weird for a motherboard and is usually related to the psu.

I would try the PSU alone first by disconnecting it from the motherboard and shorting the correct pins. (Usually a green wire and black wire you need to short together to get the psu to turn on) You'll definitely need to look into your specific model and make sure you're shorting the correct wires though so the psu doesn't catch on fire.

Or you can buy something like this which shorts the correct wires for you.

https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S/ref=sr_1_5?ie=UTF8&qid=1499978021&sr=8-5&keywords=power+supply+tester

Actually what I'll do is buy a PSU tester since I don't need to have it connected to my PC to use it. If the PSU is bad then I might be able to get away with RMA'ing the PSU with EVGA to get a new one. If the tester shows the PSU is good then I'll reinstall W10. If reinstalling doesn't work then I'll have to hope I just need to update the bios and re-overclock the CPU instead of having to replace the board and redo my cable management.

Recheck all physical connections from your PSU to your hardware and, if possible, test your PSU with something like this if you've got one.

If you can test the specific outlet you're using, too, then that's a bonus

Re seat all of your power connections, and try to boot back up. If it's still a no-go It's always handy to have one of these around:

https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S

I have had breaker trips destroy power supplies. It sucks, but the PS SHOULD have absorbed the issue and hopefully your hardware is safe.

I would recommend that you hook your machine up to a UPS. Even if it can only give you 10 mins or so of backup battery, it will clean the power (most of them have voltage regulation and sine wave regulators) and if you drop a breaker, it will keep everything alive.

Good Luck

It is possible its your motherboard, however I'm putting my money on it being a problem with the PSU.

It sounds like not enough stable power is being supplied to your components during heavy load operation like gaming.

The best way to test if your PSU has kicked the proverbial bucket is to get a tester like one of these.

>Is there anyway for me to test this

yes https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S

My method for testing a power supply is to toss in another power supply that is laying around but the tester is probably easier.

With a PSU tester like this one.

You can also do it manually with a multimeter, but I wouldn't recommend it.

A blown PSU can indeed take out core components when they go. Power supplies usually have fuses to keep this from happening but I am not sure if all do.

The only way I know of safely testing it would be something like this

Well, the only way that I know of to test a PSU is with a PSU tester, which is a handheld device like this. From my experience, this seems to be more power related, but without actually seeing it, its very difficult to tell.

Ok I have a question about this motherboard, It is an Asus A8n-e. It has a 20 pin power motherboard connector and a 4 pin power connector. Is the 4 pin 100% needed to supply enough power to this motherboard? The reason why I ask because I bought a power supply tester and when I connected the 20 pin only the +5 led came on and when I plugged in the other power cables such as the HDD, 4 pin, no other light came on.

So what I did next was use the power supply tester on my buddies power supply and everything lit up for his connectors and every other cable we tested.

Is the 4 pin power connector needed to power up the motherboard correctly? and would it cause the motherboard to turn on by itself? or would this still be the effect of a short circuited motherboard. I ask this because when I used my buddies PSU we did not plug it in and only used the 20 pin.

Thank you again

Any local shop should do it for free or you can purchase the tester yourself. It's a quick 5 second process:

http://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S

(I'm not advocating that tester in particular, just showing what it is.)

As you said no beeping, then it's not a memory issue. If the motherboard works, your next step is to check your power supply.

I recommend getting a cheap but efficient power supply tester and see if the throughput is correct. Otherwise, a replacement power supply doesn't cost too much.

If that doesn't work, it's most likely a CPU issue, which will be pretty expensive if you have to replace it, I recommend taking your computer in to a respected hardware shop to see what they can do or have to say about it before making any expensive moves.

Is there a way to test the PSU without going and buying a tester?

If it comes down to testing the GPU, I'll see if my brother-in-law has a spare GPU or will let me borrow his GPU. May not after hearing what happened to mine. :)

Sounds like a Power Supply Issue to be honest. Easiest way to verify it's not a power supply issue is to buy a power supply tester like this ( http://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S ) for about $7. So helpful in diagnosing issues when you can be sure if the power supply is working or not.

If the power supply passes at that point, it's either the Motherboard or the CPU. From then look at your capacitors and make sure they all look good and see if you can spot anything wrong.

Typically based on my experience it's usually the motherboard and not the CPU, but without testing your Power Supply (or Using a known good Power Supply). You won't know for sure.

Also as an additional note I have seen power supplies still turn on when they were not working correctly so just because the fan spins does not mean it is working properly.

If it's new, maybe it's got a warranty. You can get a tester yourself, take it to a shop, or just try to RMA it. If you're telling me that you've tripped two different breakers, then you've got computer problems of the electrical kind.

OCing it wont fix the issue. Bring it back down to normal specs. Test your PSU to see that its delivering the right amount of power, too. Make sure to run DDU to remove all drivers, and test with stock Windows drivers. Pull the latest drivers from NVIDIA (June 2015) and put those back on. In an elevated command prompt, run SFC /SCANNOW to rule out Windows issues. Lastly, run chkdsk /f to make sure the drive isnt having issues.

I suspect a bad PSU or video card, but testing it should show us the answer.

There are multiple ways to test PSUs, which you choose is up to convenience. Probably the best way is to buy a PSU tester to make sure all your connections are working fine. This does not test the PSU under load however.

The second option is to test it in another computer. Of course, most people don't just have another computer just lying around that can put the same load on the PSU. You could just take it into a nearby computer repair shop and see if they can help you out to test it.

Otherwise contact Corsair and see if you can get it RMA'd.

Your friends psu was for sure 100% good ? Check for 12v and 5v coming from yours. You can get a tester for this on amazon for about 12$. https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S

Cheapest one I could find on Amazon prime I'll hopefully only need it this one time

The only part thats missing from your speclist is your Power supply :) I would borrow a friends psu, its a Hard disk drive, it uses a motor to spin disks, could be it isnt getting enough power. Or you can buy a psu tester from amazon cost like 5-7 usd Here is one __________________And here is a video on using it

$8 bucks on Amazon. Microcenter used to have them too. Go nuts on it.

What brand and model of power supply does this pc build have? The power supply could be faulty or failing but the model and brand could be a better indication than guessing.

Buying a power supply tester is also a very good method for testing for a faulty power supply and these are cheap to buy on amazon or take your tower or psu to a computer repair shop locally and ask them to test your psu.

A GPU making buzzing sounds is a good sign of a faulty GPU or possible power supply instability issue.

Cheaping out on poor quality power supply for a pc build is never worth the compromise

I would get a cheap PSU tester or use a multimeter to check the voltages.

https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S You can test the PSU yourself with this and see if it is providing safe power.

Lol what? motherboards have a "core" rating? since when?
as mentioned in OP I have a :

CPU: AMD Ryzen 7 1700X Eight-Core @ 16x 3.4GHz [29.0°C]`

and Then my motherboard is:
https://www.asus.com/us/Motherboards/ROG-STRIX-X370-F-GAMING/

Something like this? https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S
what will that do since my computer can run benchmarked at 100% for weeks without issue? (genuinely curious)

Straight cables. Yes to the crimpers. No to the beer. I'm on narcotics for a back injury and stopped drinking as a result over a decade ago. As for entertainment. I have a Plex server with over 800 different viewing options and of course Netflix and prime. And another area of my life I keep saying I'm going to do something about, cutting the cable cord! Thanks for the PSU tester suggestion I'll look in to it. I have multiple PC's so I'm in no rush to have to get this one back up and running. And here are pics of the rig in question so I'm not being rude! Haha https://imgur.com/XvydWKh

Also do you have a link to the tester you have or suggest? I'm looking at this as it looks like it should do the job I need it to do. Insten 20/24-pin Power Supply Tester for ATX/SATA / HDD, Black https://www.amazon.com/dp/B005CTCD6S/ref=cm_sw_r_cp_apa_0EIzBb7D89004

I would suggest ether do a paperclip test on your psu EVGA

Or buy a power supply tester amazon

That is just an example, you could probably pick one up at a local computer parts store, possibly even Best Buy.

1. try a different display cable and port
2. try on board video instead of video card (no on board skip to step 3)
3. try a different video card or try the original video card in a different PC.
4. test power supply with paperclip test or Power supply tester

Maybe something like https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S from an online or local store could help. Otherwise I'm not sure what else to do. Edit: Oh that's just for 24 pin maybe something similar though.

sounds like PSU, you can buy a cheap tester and test it yourself.

https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S

Unfortunately speedfan isn't providing much useful voltage info, taking measurements is the only way to determine if it's healthy. I've never used one so I can't vouch for how effective they are, but there are inexpensive PSU testers available. Otherwise, if you know someone who can help you take measurements, here are some instructions.

Some other suggestions, in no particular order:

• Run memtest again
• Visually inspect your mobo for bad caps.
• Stress test your CPU.
• Reset BIOS (write down your current configs first!)
• Run memtest a few more times

A PSU tester is probably your best bet.

Do you have a PSU tester or multimeter to check the PSU with? If not, disconnect your PSU from everything but power and try the paperclip test.

If the PSU tests fine, either there's a problem with the mobo, or something isn't plugged in properly. If you post a picture of the inside of the case, folks here can let you know if anything jumps out at them.

Absolutely. If preferred, power supply testers are pretty cheap.

Remove the PSU and try the paperclip test on it. If it turns on it may be ok. But, in order to test the voltages you would need a proper PSU tester, such as one of these.

You could get a PSU tester

Have you made sure the outlet still works?

You've already tried turning it on, so now you gotta test the PSU on it's own. Need a digital power supply tester or use a paperclip to test it outside of the case. Some PSUs come with a 24pin adapter that you can plug in that's the same as the paperclip method.

The paperclip method should force the PSU to turn on when the switch is flipped. If it does not turn on, then we found your problem.

no the system doesnt make a noise fan dont spin nothing

I mean, maybe test the psu with this

This is what I got coming.

Yeah. There's no other way to test a power supply. None at all. Certainly not for less than $10.

• test the PSU, get one of these https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S
• if PSU is fine, test every other component
• jump booting the power pins with any metal object is totally fine

Might be worth investing in a PSU tester before you go through replacing it.

I have something like this, ends all guessing so you can move on to the next thing...

https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S

you could fry the other system. A faulty PSU could just do nothing or it could cause serious damage. You are better off buying a power supply tester

https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S

I don't know about software, but there are tools like this:

https://www.amazon.ca/PC-Power-supply-tester-LED/dp/B005CTCD6S

With things like these. Though er might be another way but I doubt it

You can buy a PSU tester pretty cheap. Here's an example: https://www.amazon.ca/PC-Power-supply-tester-LED/dp/B005CTCD6S Also: Is it possible that your CPU is overheating due to failed heat sink compound?

https://www.amazon.com/dp/B005CTCD6S/ref=cm_sw_r_taa_x0TzxbR31JNCX Usually between 10 and 25 dollars.

Some no-name brand I bought in a store, very similar to this though. http://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S

Actually, rereading your first post, the PSU could be okay. You could try purchasing a tester to find out.

I guess if you want to rule out power issues, you can get something like this:

http://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S

I use a different type, but it will tell you if the power supply is outputting the correct voltages at your house.

If it isn't that, then it must be EMI. What is the case made of?

Build a faraday cage for your computer.

http://www.thesurvivalistblog.net/build-your-own-faraday-cage-heres-how/

Yep, something like this or putting it on another computer, of course.

Sounds like the motherboard, just from the fact that the switch didn't turn it off. But that's just a guess. Could just as easily be the switch.

I don't know how 'handy' you are but you can rule out a dead PSU by bridging the switch pins:
