which video card is better

[BaldEagl]

so a PSU running ,+12V1@19A,+12V2@20A with a Efficiency of 75% should work then right? or wrong?

just thought i might be easyer to let yall see the specs for it and make and model

ow and one more question how hard is it to share rails? ? ? ? i have never had to do this before. i always bought a 700Watt with triple rail +12v with 40A at lest thats what i was told to trust as a perm. PSU salute and thanks for all the help so far gents

That should work but it's going to be close.

75% efficiency?  That supply is going to crank out some heat and cost you more than a more efficient supply would.

Let me show you what I mean by using some arbitrary numbers.

If the load on the supply is 300W. 

At 75% efficiency the supply use 375W from the wall. 
At 82% efficient will use 354W from the wall.

The extra power the lower efficiency power supply uses is converted to heat, thus heating up your environment more.

Just FYI.

I'm not a fan of Corsair power sups.  At that point you would be better with the 610


PC Power & Cooling / Silencer / 610-Watt / PCI-Express / SATA-Ready / Copper Power Supply, 80Plus - 85

IIRC, Corsair's are made by Seasonic.  They're excellent quality PSU's.

thank you all for your help salute

[BaldEagl]

Much much better choice.  Always try to find 80+ certified.

now no one did tell me how to use both rails. my squadie cant afford a diffrent PSU so he is going to try to use the one he ordered. is that a wire harness or what? ? ?

As long as the PSU has a PCIe connector you don't have to do anything except plug it in.
