GTX280 PSU recommendation

post #1 of 10
Thread Starter 
Ive got a Corsair HX620 powering current system specification below. Would it be sufficient if I swapped it out for a OC'd GTX280 (single)?

600watt? yep.

question, why not go HD 4870 crossfire instead?

It should as long as you have one 6-pin and one 8-pin on your power supply.

Well, the PCI-E connectors are 6/8-pin, as such...



Would this be okay as well?

Look at the the female connector at the side of this card:

It should most definitely fit.

Well, I know the 8pin connector was made for ATI graphics cards, just wasnt sure if it was the same connector on the new nvidia cards

Yeah, the 620HX actually seems to pump out more than it is rated to. So it'll definitely be able to power a GTX280. However, I don't think it's worth it to buy one now, not when a 55nm version will come out soon and due to the fact that the 4000 series are doing so well.

Yes, that looks to be the 8 pin pcie 2.0 connector. The only 8 pin connector that you DONT want to plug into the card is the old 8 pin motherboard molex. It wouldnt fit without forcing it onto the plug anyway so you dont have to worry. http://www.evga.com/articles/397.asp

Seems like that will do fine as long as the 12v rail amperages (on the psu) are at the minimal recommendations or higher. Hope this helps!
