Does it matter which cable I buy?

post #1 of 9
Thread Starter 
I'm letting my friend borrow my HD 5970 for 2 weeks but his PSU doesn't have an 8-pin PCI-E adapter on it.

Can I just buy an 8-pin extension or does it have to be a 6-pin to 8-pin adapter?

If it doesn't have an 8pin on it then I don't know how an extension would work.

The 6 pin to 8 pin would be the better option but I wouldn't recommend it

It's an OEM 850 watt PSU.
It's over-rated by about 25 watts. lol

It supports dual 8-pin processors, but only has 4 6-pin pci-e adapters.

Is it in an Alienware or something? (or Ibuypower)

Never heard of a Dell or HP with an 850w psu.

the 2 pins on the 8 pin are currently used as grounds, just get a 6 to 8 pin adapter.
Most alienware's i've seen have had newton power psus.

Mine came with a Silverstone Zeus. I cannot tell what my friend's is so I'm pretty sure it's just OEM.
