I use these JacobsParts PCI Express Power Splitter Cable 8-pin to 2 x 6+2-pin (6-pin/8-pin) 18 AWG https://www.amazon.com/dp/B07611QXG4/ref=cm_sw_r_cp_apa_ipYNBbJ5AE740
But only plug in 1 6 pin. Depending on the card I actually sometimes use both to power two risers.
I just noticed that that link may be a referral Link idk tho. I just copied pasted from Amazon. Sorry of it is
Link your psu but it's kind of surprising if a 1000w only has 3 pcie connections my 850w has 5, you can order y splitters to make 6+2 pins connect into two more. https://www.amazon.com/gp/product/B07611QXG4 Those are quality but not on the long side, also surprised your gpu only has pcie 6 pin is it older? you might be better off and safer just getting a newer model with the 8 pin pcie slots to dual 6+2 pin
It's all good except for using SATA on the last two risers. You should buy two of these PCI-E splitters and use them on the two single connector VGA cables to turn them into dual VGA connector cables. Then you'll have enough connectors for the two SATA risers.
Alternatively the JacobParts 8 pin to 2x 6+2 pin splitter would also work for your purpose, and you get a much more useful cable for the same price.
What GPU and PSU do you have?
For my Vega on my Corsair HX1200i (which has dual 6+2 on each PCIe cable), I got myself a splitter like this, connected the dual-head part of the splitter to my Vega, then connected the riser and splitter to each head of the PCIe. I can do this because these rails handle 300W, and I’m only pulling around 170-180W.
If your PSU can only manage a single-head rail, you need to figure out the total power draw of your card. If it’s under 150W, then you can do the same.
The SATA thing seems to be... I wouldn’t say “overstated”, because people have had serious damage, but many of us are having no trouble with them, especially when undervolting the cards.
Having said that, if you want to cut down on clutter a little, I would suggest a splitter.
For my Vegas, I put the two ends of the splitter into my card (also making it easier to disconnect from my rig if needed!), then plug the second head of my PCIe power into the riser. As long as you’re not pulling more than 300W (or 150 if a single-head PCIe), you’ll be fine.

A cable spitter assuming ur psu is non modular.
If modular just find a custom one.
Mileage varies, but as long as he does have two 6-pins available, he could infact use a dual 6pin to 8-pin splitter: https://www.amazon.com/JacobsParts-Express-Power-Splitter-Cable/dp/B07611QXG4?pldnSite=1
​
However, he could not use the one you linked because one 6-pin won't supply as much needed as an 8-pin connector.
https://www.amazon.com/JacobsParts-Express-Power-Splitter-Cable/dp/B07611QXG4 That's not an ad, just for reference
It needs three to power up. You can try to use an splitter to split 1 8-pin to 2 8-pin connections.
EDIT: On the specifications page for that PSU, it says it comes with 4 x 6+2 pin connectors. You don't have any more cables?

I'm running two power supplies because my main PSU only has 2 PCIe 12V outputs.
Generally EVGA and Corsair are your best picks. Even among those brands though, there are different suppliers that have different quality of parts. It's a rabbit hole that I go down sometimes but it's such a waste of time TBH. Bottom line is this PSU is a rebranded single rail Super Flower PSU (pretty good) with 5 year warranty (pretty good, and realistically all one really needs in a PSU).
Will it power 8 GPUs?
It has 6 PCIe lines, 1 (extra) CPU line (can convert to PCIe), and 4 molex lines. So all total 11 connectors. Each GPU needs a connector, and its riser needs a connector. So 8 GPUs needs 16 connectors. This falls short by 5. Which is why I like to recommend two smaller (750W or 850W) PSUs typically instead of 1 big PSU.
All hope is not lost though. If you're powering smaller GPUs (and it looks like you are) then you can buy splitters (like these) to turn one PCIe connector into two.
Things get tricky when you use splitters on a line that already has 2 PCIe connectors on it. Use this link to confirm that you're not overloading your line: https://www.gpuminingresources.com/p/psu-cables.html
Another tip: Use risers that allow for power from a molex connector.
update: I suggest this one (https://www.amazon.com/CORSAIR-Platinum-Certified-Modular-Renewed/dp/B07L8NHNB3) it's better (albeit "renewed") and cheaper.
Hold on, I'll find the splitters you need.
EDIT: Here you go:
EDIT 2: You can use the 8 pin EPS 12v CPU lead as well:

I bought these, work great!
https://www.amazon.com/gp/product/B07611QXG4 is what the people in my little mining group use.
Aren't 8 pins rated at 150 watts? If so, then having more than two 75 watt draws on one 8 pin cable would still overdraw.
Unless I'm missing something. Which is very possible.
