Question concerning PSU and GPU

post #1 of 10
Thread Starter 
Hey guys. I have a question for you.

I purchased this card:
http://www.newegg.com/Product/Produc...82E16814121432

I have a tr2 rx 850w thermaltake for a PSU.

There are 6 connections that are black that are FDD\\SATA\\MOLEX
There are 6 connections that are red that are PCI-E

1. Am I supposed to use the black FDD\\SATA\\MOLEX for the video card, or the PCI-E? I only have the black in use so far in my computer.

2. IF I'm needing to utilize the red PCI-E instead, is the cables the same for both the black and red (the difference being only inside the PSU) or are there specific cables for black and red (the plugs look the same outside of color difference it seems). I don't have any cables for red so I'm curious when I buy some at the store.

Thank you.

Welcome to OCN

You need to use the red PCi-E connectors for your gpu

Nice card too, wana by me one?

Use PCIe. I believe the red end goes into the PSU.

Edit: I don't think I understood your second question.

Well interestingly enough I don't have any red cables, just black. Can I use the black ones and plug them into the red PCI-E plugs in the PSU? I can't tell any difference between the cables outside of simply the color.

My video card requires a 6 pin and an 8 pin. I only have one black 6 plug, one black 6 + 2 plug, and I don't remember but I believe an 8 black plug that ends with a 6 red plug.

Sorry yes, use the pci-e one into the card and the red end goes into the psu

Probably my fault here. Sorry for the trouble.

I don't have any red ends at all except for one which isn't enough to cover 14 pins anyway. All my wires have black ends except for a black end to red end (which again cannot cover all 14 pins)

I'm not at home but i took these last night. This should help:

As you can see, it takes 6 and 8.

Note:
Card came with this...a 6 pin + 6 pin to an 8 pin. All black?

The only cables I have available. It's an 8 pin from PSU to 6 pin, and an 8 pin from PSU to 6 + 2 pin.

I do have an black 8 pin to red 6 pin but once again I have to end up covering 14 pins on the card.


So what's the game plan? Plug in the black headed cables into the red PCI-E slot and video card?

Sorry for all the questions. All this time I always had everything running from the black molex/fdd/sata section of my PSU including to my card and never had anything coming out of red, but this is an expensive card and I don't want to screw it up.

Also Ryan, I found out something interesting about Daft Punk you might find entertaining. I'll hit you up with a PM later.

oh, and t-ramp, in response to you, question 2 was pretty much asking if the cables are universally acceptable in both black (fdd/sata/molex) plugs and red (PCI-E) plugs regardless of the color of the cable ends (ie can a red cable be used in black, and can a black cable be used in red).

No. Even if they fit in the alternate port, PCIe is entirely 12v and ground wires, while molex and SATA also have 5v, and SATA adds 3.3v as well.

Been asking around. Most everyone says the wires are universal and there's no standard (as long as they fit the slot), and every other person says red and black headed cables are completely different even though they fit the same slot. Guess I'll go better safe than sorry and go to Fry's today and get a red 6 pin and red 8 pin or 6 + 2 pin. Kind of odd my PSU didn't come with ANY red head cables. Doubly weird that the GPU came with a converter cable that's all black.
