Hi guys,
I currently have this PSU : http://www.frys.com/product/5086635?site=sr:SEARCH:MAIN...

I know that the gtx 295 comes with an adapter 6pin to => 8pin PCI express adapter so I don't need to worry about not having an 8pin that the Antec only have 2x 6pin PCI.

BUT my question is will my 500w Antec run gtx 295 fine and is future proof for the new nvidia card gtx 480 or 470? What you guys think.. it should be ok?

My PC SPEC:

*AMD phenom x4 black edition 965 3.4ghz
*4 GB ram DDR 2 kingston hyerx
*350GB internal harddrive .(planning to get Western Digital Caviar 1TB SATA) and use the old one as STORAGE)
*DVD/RDVD cd-rom
*Antec 500w EA-500D Earthwatt
*graphic card : planning to get gtx 295x ==> later sell and get gtx 480.

SO THERE YOU HAVE IT.. think I don't need to change my PSU .. it should run gtx 295 FINE? and hopefully gtx 480 since it should have almost same power requirement as gtx 295 (ASSUMING).

No it's way too small. I would not go with anything smaller than 750 watts with at least 50 amps on the 12v rail. Make sure it has the correct plugs for the video card so that you don't have to use any adapters.

Wayyy too small. A GTX295 is 2 GTX275's on a single card, you would usually use a 750W unit for 2 GTX275's in SLI mode. The EA500 provides 34A(408W) on the 12V rail, the GTX295 can use up to 289, the 965 can use up to 125, oh look we are already over the available 12V power with only two components. The EA500 is a good little unit but even it will either automatically shut down everytime you try to boot or just blow itself to hell. You should have a 750W PSU for a dual GPU card, and based on reports you may need a 750W to run a single GTX480. Never skimp on a PSU its just bad.

Edit: The corsair 750W is my normal recommendation for dual card setups, its a good unit with plenty of power for a single GTX295, and hopefully 2 GTX480s but we will see.

Yeah the Corsair is excellent! That's the one I'm using and it's been great.

Same reply as above:

Is this CORSAIR CMPSU-750TX 750W ATX12V / EPS12V .... More than enough for gtx 295 and future cards such as gtx 480 and upward in future?

Additional .... or should i go for : CORSAIR CMPSU-850TX 850W ATX12V 2.2 / EPS12V 2.91 SLI

Easy. I would get the 850. It's only $20 more for a extra hundred watts and ten more amps on the 12v rail.
