Hi All

Just A Quick Question For All You Knowledgable Folk Out There. :D

Im Thinking Of Getting a 2900 Graphic Card And In My Machine At The Moment I Have The Following.

P5B Wifi Deluxe Motherboard
6400 @ 3.2 GHZ
2 Gig Corsair Dominator Memory
3 x 500 Gig Hard Drives
3 x Dvd Writers
24 In 1 Card Reader
Alphacool LCD Display Module
Corsair 520 Watt Modular PSU


Can Anyone Please Tell Me If My PSU Is Powerful Enough To Run All Of The Above With The 2900 Graphic Card? :confused:
I Did Explain To One Of The Guys On The Desk At Overclockers What I Was Planning To Buy And He Said The 520Watt Would Be Plenty To Run All Of The Above. :eek:

Im Just Wondering As I Dont Want To Buy The 2900 And Then Find Out This 520 Corsair Wont Run All My Stuff On It..

Any Help Is Much Appreciated...

P.S I Did Have The X1800XT In My Pc Until Today When It Decided To Fail On Me... :mad: Typical


Thanks For Any Information You Might Be Able To Provide...


All The Best

Should be enough...
But only just, make sure to split all the ide devices accordingly over the corsairs rails...
 
without breakign a sweat isnt really true, his 3 burners alone, if they are burning, use 75 watts total... Hence it's important he doesn't connect everything on 1 rail and forget the other...


Oh with ide devices i just meant hdd's, dvd/cd drives in general, doesn't matter if sata or not...
 
It should run it, but have you not considered the better 8800 GTS 640mb, it uses a helluva lot less power, and is a lot cheaper. :)

Plus the nvidia 8800gts has better drivers ;)

Oh, and ATI drivers are mint compared to Geforces imo. (I recently changed an x850xt to a 7950GT and had to download the nHancer stuff to get half my games working :D)

75w, or 6amps max on the 12v rail. 2x 8800gtx's running full pelt would pull 25-26amps. if he were running two of them that would leave him with 8 amps to spare but he's only intented on running 1x 2900 card. so lets say that pulls 15-16 amps (192w). that would be a 12v load of 22amps on a psu that has 40amps available - 18amps (216w) available for anything else that needs it.


that psu will cope easily.

I thought the 520w Corsair was a single rail PSU from reading other posts on here.. :confused:

I think you better go and read some threads on here about the ATI HD2900xt before quoteing the ATI drivers are mint compared to the nvidia 8800gts drivers...

But your only comparing 1 card to the whoole buisness.
Overall ATI have better drivers. The only poor driver support is for the 2900 which is understandable as it has just come out, like the 8800gtx at the start it didnt have the best drivers but nvidia are getting there.

But the OP is thinking about a HD2900xt card

No, it has 3...



But i agree get a 8800GTS, faster, lower power, cheaper...

no, it has one, unless it is proven the 12v1 and 12v2 points in the psu are actually separate. http://www.jonnyguru.com/review_details.php?id=28

This demonstrates that if the two rails are in fact separate, there is no OCP (over current protection) on each rail. Outside of a few traces zig zagging across PCB, I couldn't find how even 12V1 and 12V2 are separate, but I'm going to give Seasonic (the OEM for the Corsair units) the benefit of the doubt and say that we seem to have two 12V rails here, neither with any kind of "limit" on them.

OK then three rails it is..(Looks to be roughly the same setup as my Enermax Infiniti 720att)

The "official" word from Corsair was the following:

12V1: ATX 20+4, 4-pin +12V and 8-pin +12V
12V2: PCI-e 1 and first two peripheral connectors
12V3: PCI-e 2 and last three peripheral connectors
