Quick pcie question

[CorruptedSanity]

My power supply came in the mail today, corsair TX650M, and I was checking out some of the cables that came with it.  This is my first build and what I'm wondering is if I get a gpu that has multiple pcie connectors, can I use this single cable that has two 6+2 on one end and an 8 pin on the PSU end? Or do I need to run a second cable?

 

The PSU came with two of the pictured cables. 

 

Thanks in advance, probably a simple answer but better safe than sorry as they say.

you can run 2x6+2 off a single space on your PSU

Awesome, thanks for the quick reply.

Eh, it's not recommended to do that for high power cards. It will probably work but will stress that cable. If you can (99% of the time you can), just use a second cable.

The PSU only has 1 output for PCIE power. Hence why they included that cable. 

If he does not use more power then what it is rated for, it will be fine.

You're right. Still, a 650W PSU with only one pcie cable? That's pretty dumb IMO.

The PSU does include two of these cables and has two 8 pin pcie outputs. 

 

Corsair also says it's, "multi GPU ready," so I guess that's why they give you two of these cables.

Thats just marketing BS  Your PSU has 1 output for the PCIE cable with the 2 6+2 connectors. The other one is a 8 pin CPU connector and cannot be used for a GPU.

So even though there's a hard wired 4+4 eps cable (semi modular PSU), the second cable labeled pcie is actually for CPU power as well? But there's no other 8 pin cables that I can plug into the PSU?

The manual / datasheet is a tad unclear i noticed. You seem to have 2 PCIE cables and if i'm reading it correctly also a 8 pin EPS/ATX12 cable? and 1 attached to the PSU itself?

Looking closer at the ports i would say that both are PCIE and you should be able to put the 2 connectors in. Even tho it looks like it says 1 is for PCIE and the other for CPU.

 

Tldr. i might be wrong

Yeah there's one non modular 4+4 labeled eps and then two modular 6+2 pcie each with a second connector daisy chained on the end.  So a total of 4 pcie connectors.

 

The wording on the PSU is what confused me a bit as well
