Hi,

Will this PSU EG495P-VE handle the HD 3870 X2? A single HD 3870?

PCI Express based PC is required with one X16 lane graphics slot available on the motherboard
550 Watt or greater power supply with two 2x3-pin PCIe power connectors required (750 Watt and four 6-pin connectors for dual ATI CrossFireX) .

those are the system requirements so in theroy it wont

For the HD3870X2 I would say you should have at least 600w... the "sweet spot" for high end pc's is probably 750w. That can handle just about anything you throw at it, unless you're going to do 2 HD3870 X2's in crossfire.

For a single HD 3870 I think your current voltage is fine.

Thnx for the fast replys, I would rather wait and see the GTX280 and HD4870.:)

485 watt power supply is still going to be an issue with dual gpu cards. ATI's are very power efficient but your still looking at 290 watts just for the video card at load. That leaves you less that 200 watts for all the other components. You can check by looking here.

500W is adequate for a mid-range video card with plenty of power for system components. The motherboard, cpu, RAM and expansion cards altogether never pull as much juice as the video card. I would say give yourself 300w for the entire system except the video card. With a high-end card, go 600w. for SLI/Xfire, 750w. That is the most any such system has EVER been recorded as pulling. Google it.
