Reddit reviews PCI-Express PCIE 8 Pin to Dual 8 (6+2) Pin Video Card Y-Splitter Adapter Power Supply Cable

I was about to say, ideally you would've wanted the CX500M. Your system should still draw less than 430w though. You may want to check a PSU calculator to get an idea of how close it'll be.

Nobody wants to recommend using the molex to 6-pin adapter. At the end of the day though, they give those adapters out for people in your situation and some people use them.

I was looking for a cable that would take the 8pin (150W) connector and split it into 2x 6-pin (75W) connectors but I didn't see any. I found one that splits it into 2x 6+2 pins, you just wouldn't use the +2 pins. That may possibly be a cleaner long term solution compared to using the molex adapter; then again, they're supposed to both come from a single 12v line.

Maybe with something like that http://www.amazon.com/PCI-Express-Video-Y-Splitter-Adapter-Supply/dp/B00A3OVG4W

The most power thirsty of 970's is the Gigabyte 970 which has an 8 and a 6 pin. A dual 6+2 cable is the most elegant solution. You could always use the included molex adapter that comes with the GPU, but its not pretty.
It doesn't need to be connected to different modeler connectors at the PSU, as its a single 12v rail anyway.

Hey I found the cable you were looking for (8 to 6+2 connector)

Your PSU should have no problem running a RX 5700 XT if i were you though I’d wait till 3rd party retailers came out with theirs cuz the blower style cooler is trash

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

JacobsParts PCI Express Power Splitter Cable 8-pin to 2x 6+2-pin (6-pin/8-pin) 18 AWG are inexpensive and work great; I use these for splitting to power my riser.

PCI-Express PCIE 8 Pin to Dual 8 (6+2) Pin Video Card Y-Splitter Adapter Power Supply Cable are a little longer, but more expensive. Probably more useful for splitting to a different card.

You might find these on eBay for cheaper (Jacobsparts sells a 5-pack for $13, and no shortage of direct-from-China sources), but I hate waiting.

I have that power supply and I run 7 x 1070s that have 2 8 pin Power plugs just fine... set your power limits to around 115-125 and you’ll be fine.

Thank you so much! I'm going to order this cable! Thank you for the help!

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.

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 !

>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.

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] (https://www.amazon.com/PCI-Express-Video-Y-Splitter-Adapter-Supply/dp/B00A3OVG4W)?

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.

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.

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.

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.

I'm currently using a molex adaptor in my portable rig for my 270x and was wondering if this 6 pin splitter:

http://www.amazon.com/PCI-Express-Video-Y-Splitter-Adapter-Supply/dp/B00A3OVG4W/ref=sr_1_2?ie=UTF8&qid=1418611739&sr=8-2&keywords=pcie+2+6+pin

would work to replace the molex cables, or if I should just get 2 single 6 pin connectors for it.

The PSU is a Corsair CS450M.

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

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

2 questions:

Would there be a huge performance loss in using a EVGA 770 4GB Superclocked in SLI with a 770 4GB Classified as opposed to a second Classified? The stats on them look pretty similar. I kept waiting on the Classified to hit B-Stock, but I can get the Superclocked for the same price as the B-stock Classified and get my SLI up and running now.

Second, Are [these] (http://www.amazon.com/dp/B00A3OVG4W/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=VTAFIC8F5I9Z&coliid=I1LH9OGTPHS0SF)
alright to use with SLI 770s? Or should I use 1 cable for each power connection to the PSU? Would help with keeping cable clutter down.

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).

Just get Y splitter https://www.amazon.com/PCI-Express-Video-Y-Splitter-Adapter-Supply/dp/B00A3OVG4W

What adapters would be safe to do? Split the 8 pins? I think that's not recommended?

These? https://www.amazon.com/dp/B00A3OVG4W/ref=asc_df_B00A3OVG4W5284746/?tag=hyprod-20&creative=395009&creativeASIN=B00A3OVG4W&linkCode=df0&hvadid=216539509836&hvpos=1o1&hvnetw=g&hvrand=25607512662011782&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9033394&hvtargid=pla-373858443798

I posted this earlier, but it didn't get much attention. To this thread!

My friend is building a computer and bought an r9 280x gpu with a Corsair CX 600M PSU. The 280x requires both a 6 and 8 pin pcie power cable, yet the 600M came with a cable like this (an 8-pin to two 6+2 pins).

Can he use just that cable for his 280x or will it run into power problems due to it splitting?
