2900Pro Power requirements?

[lordsegan]

Does anyone know what the official power requirements are for the 2900Pro cards?

I have looked and been unable to find anything.

I have an Enermax 485W dual rail noisetaker.

I think 2x 18A rails.

How would that do with a 2900PRO series card?

I am running a 4200 X2 and 3x hard drives. Sound Blaster and 2x Optical drives.

I would suggest getting a better psu... I would reccomend atleast a 600 watt since you have 3 HDD

For my old one, are we talking a blow up when I plug it in, or just not max OC performance.

You'll be fine with 36A. The hard drives typically eat an amp apiece. Throw in 10-12A for processor and motherboard + cards, and that still leaves 20A (240w) for the video card to suckle on.

According to this review, the card uses about 25w more than an 8800 GTS, and the 8800 GTS has been confirmed at about 110-120w load. That puts this card at 150w max (12.3A).

Only if you don't use the lite version. The "pro" version has some worth. Your PSU has more than enough headroom for what you are doing.
