I use VGA splitters, so 8 pin VGA from PSU to 6 pin (riser) and 8 pin GPU. I had to buy them from amazon. PCI-Express PCIE 8 Pin to Dual 8 (6+2) Pin Video Card Y-Splitter Adapter Power Supply Cable https://www.amazon.com/dp/B00A3OVG4W/ref=cm_sw_r_cp_api_EBYeAb846HPXW
Got it. I found a similar cable on Amazon that isn't coming from China and is slightly cheaper. I think this will work - what are your thoughts? I'd obviously not use the 2-pin optional part.

Im using evga 750 g3. 2 cards per molex and 2 cards per 6+2 pin which i split. I use https://www.amazon.com/dp/B00A3OVG4W/ref=cm_sw_r_cp_api_j54SAbP5AS9Y2
To split the 6+2 pin
And the evga 3x molex cable to power two risers.
4 cards per psu
This is my 3rd rig I don’t have these issues on anything else.
I am currently powering each of my Zotac 1080 Ti Amp Extremes a Corsair (Type 4) 8 pin PCIE at the PSU to dual 8 pin PCIE (6+2) at the GPU.
Instead of powering my risers with molex or sata would it be okay to use the same kind of cables to power two separate risers using the 6 pin PCIE?
I would be plugging an 8 pin PCIE into the PSU then plugging one end of each 8 pin (6+2) PCIE cables into a 6 pin on the riser. Obviously, I wouldn't be using the +2 pin on either riser. Is this safe to do to power two separate risers? I assume the each 6 pin from the PCIE would be rated for 75w since the 8 pin PCIE is 150w before it splits to the dual 8 PCIE (6+2)?
Here is a picture of a cable similar to what I am talking about: https://www.amazon.com/PCI-Express-Video-Y-Splitter-Adapter-Supply/dp/B00A3OVG4W
I was giving this some thought and realized/remembered you can just get some 1 x 8-pin to 2 x 8-pin pcie adapters. Your cards have a max TDP of 180W, which means you'll be able to split a single 8-pin in two without fear of overdrawing the cable. (Yes, a single 8-pin can handle max 150W, but your riser compensates for about 47 of those 180W at peak draw)
https://www.amazon.com/PCI-Express-Video-Y-Splitter-Adapter-Supply/dp/B00A3OVG4W
Get one of those for each card and you are good to go my man. And sorry about earlier, I hadn't had coffee - wasn't firing on all cylinders.
What adapters would be safe to do? Split the 8 pins? I think that's not recommended?
You’d just need two extra 8 pin to dual 6+2 cables (since PSU should already come with 2) I ordered these for my rig: PCI-Express PCIE 8 Pin to Dual 8 (6+2) Pin Video Card Y-Splitter Adapter Power Supply Cable https://www.amazon.com/dp/B00A3OVG4W/ref=cm_sw_r_cp_api_BG-9zb8KX9B66
So from your PSU, you have an 8 pin plugged into each vga port on it. On the other end of that cable you have two 6+2 connectors- with one set of 8 pins plugged into gpu and the other strand you have the 6 pin plugged into the riser and the leftover +2 plug doesn’t matter.
Not sure if it helps, but, I'm pretty sure that PSU was actually made by PC Power and Cooling.
You could use a PCI-E 8 pin splitter like this - https://www.amazon.com/PCI-Express-Video-Y-Splitter-Adapter-Supply/dp/B00A3OVG4W
That said, I'm not a fan of using cable adapters to make a PSU work.
No adapter. Its the standard GPU power cord that comes with the PSU. It looks something like this.
Since my GPU requires a 6 pin and 8 pin to be fully powered, and I only have the dual 6+2 cord I used one full 6+2 and only the 6 pin connector. I know, I'm sorry, its really confusing for me to explain.
Hello !
I have a 6xEVGA GTX1070 FTW and my PSU is EVGA SUPERNOVA 1300 G2. I have a question: How to power up those cards ? I'm wondering whether to buy those adapters: https://www.amazon.com/gp/product/B00A3OVG4W/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 or just second PSU. Let me know in the comments !
Hey I used the search bar to find this!!! I have this exact same problem. I have XFX RX 580's from BestBuy. They require 8pin and a 6pin power connector. But the cards wont boot with just the 8 pin the lights come on but the fan doesn't spin. The card wont be recognized. It needs both 8pin and 6pin for it to work. How do I get these cards to boot with just the 8 pin? I have 2 750 Watt EVGA. Would I need this converter cable for it to work?
https://www.amazon.com/PCI-Express-Video-Y-Splitter-Adapter-Supply/dp/B00A3OVG4W
That makes much more sense. Thank you! It's just frustrating, I didn't return the card :). I bought this adapter and hope it works as everything I've read said it's exactly what I need. Thanks again.
So this connected to the RED vacant 8-pin connector on the back of my PSU?
Also, there are two vacant 8-pin slots, does it matter which I use?
Ah I see! Yes mine is non-modular. So I can buy a 6+2 PCIe cable like the one pictured (Like this), and it'll work? Last question: What part of the PSU do I plug the PCIe adapter into? I know where to plug the adapter into the GTX, but not where the other side goes. Sorry if it's a dumb question!
Interesting I thought that one was 2x8pin only..
That said, just plug in one of the other 8pins from a second/fourth cable if using a modular psu like my EVGA SuperNova G2 that or get a single 8pin to dual 8 pin adapter.
i believe it is seated all the way the fans are on and the lights are on and i am using two separate cables, these ones, however i am using the two male ends and leaving the female end open
600w and they are I'm wondering if the card is getting power though, i am using the two male ends of this cable and leaving the female end open, because i no longer have the cables that came with the power supply
what psu and what gpu?
https://www.amazon.com/PCI-Express-Video-Y-Splitter-Adapter-Supply/dp/B00A3OVG4W
Yeah, that should be the 2 "extra" pins.
If it looks like the bottom left connector on the product page of this, then you are good.

These are in the middle of shipping to me, should I cancel and buy yours instead?
I have ordered a bunch of these to replace all my sata connectors eventually. https://www.amazon.com/PCI-Express-Video-Y-Splitter-Adapter-Supply/dp/B00A3OVG4W
Here are the exact ones I use: PCI-Express PCIE 8 Pin to Dual 8 (6+2) Pin Video Card Y-Splitter Adapter Power Supply Cable https://www.amazon.com/dp/B00A3OVG4W?ref=yo_pop_ma_swf
Did it come with 8 pin (plugs into psu) to 2 8 pin with 2 side pins that slide off? Looks like this
https://www.amazon.com/dp/B00A3OVG4W/ref=cm_sw_r_cp_api_nJgqAb2NZTWJS
Just get Y splitter https://www.amazon.com/PCI-Express-Video-Y-Splitter-Adapter-Supply/dp/B00A3OVG4W
I ordered these but I think they’re wrong. PCI-Express PCIE 8 Pin to Dual 8 (6+2) Pin Video Card Y-Splitter Adapter Power Supply Cable https://www.amazon.com/dp/B00A3OVG4W/ref=cm_sw_r_cp_api_1IQ-zb8PDS7YQ
If you had four 8-pin PCIE slots on your PSU, you would need either:
1) 8-pin to dual 6+2 pin splitters
or
2) Dual connector PCIE cables (EVGA usually includes at least 2 of these cables with their PSUs. The ends with the red arrows are the ones that plug into the actual GPU, whereas, the other end plugs into the 8-pin connector in the PSU).
I haven't used these before so I can't vouch for them:

Instead of using 2 separate 8 pin cables for my 1080 TI can I use one of these?

>So basically I didn't know that a 1080 FTW had 2 8 pin slots and this basically overthrew my mining rig operation that I just built. I've read up on Y splitter cables and they do not seem to be that great in terms of being reliable cables. I do not have enough power slots on my PSU to support all the Evga 1080 FTW's I have.
>I was looking at these from amazon and was wondering if one of these could support 1 1080 FTW : https://www.amazon.com/gp/product/B00A3OVG4W/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
You need this.
Stay away from any Molex or SATA adapters.

Best way to go. One came with my GPU when I got it. Check your GPU box, one may have come with it as well.
http://www.amazon.com/PCI-Express-Video-Y-Splitter-Adapter-Supply/dp/B00A3OVG4W perhaps? What do you have on your PSU and what does the video card have?
sorry its this cable theres two male ends and a female
