I had an old ...maybe 15amp power supply running a micro atx board, 3200 amd proc, 4 512 sticks of pc3200, floppy, dvd-rom drive and god knows whatever else and a 640 card. had no problems. don't count it out until you try it.
I bought it new from a guy at Starbucks for 80 dollars. And no I haven't set it up yet.
Basically I just wanted a decent cheap card to get by with for a year or so. Maybe I misread something on newegg. Its said you need a minimum 400 watt 12v capable of 26A. I took that has 26A on the 12v rail....maybe i'm okay.
You should be Ok since your PS puts out 29A combined through the two rails, provided you don't have the system laden down witlh bunches of hard drives, optical drives, big fans (120mm or greater), and an overclocked high wattage processor.
You should be just fine. Personally I don't see the point in spending money on an 8800GTS 640 now adays unless you already have another one and want to run them in SLi. Hope you got a good deal on it .
Well....its a case of not thinking about the power when I bought it and I was in a hurry. So yeah i didn't exactly think it out straight because I bought it on an impulse. Still "if" the PSU can hack it i think it was a decent purchase. Otherwise, yeah 30 more dollars and i'll get an antec
some of u guys dont know what the f**k u are talking about. The evga ssc version of the 8800 gts 640mb has 112sp and more mem, memory bandwidth and rops than the 8800gt. The card will perform similar and HIGHER than the 8800gt expecially with higher res and or AA. With a minor overclock im sure he can get his shaders to 1500mhz(same as 8800gt) i sure as hell did on my old 320mb and that was a vanilla card!!!
Well i'm pretty happy about it. I am using this machine mostly for graphic work (ie. photoshop, flash, autoCAD etc.) I bought the 8800 to play the occasional game such as CS:S, and strategy games. I'll probably also end up playing the Stalker series and Assassin's Creed at some point. The card came with Crysis which I don't really like so I gave that away. I don't have a very flashy monitor - just a Samsung 206bw 20".
I did a calculation on the Amps and it looks like I'll have plenty with my setup, i'll know for sure wednesday when everything goes together. Thanks for everyone's imput
Just thought I'd follow through and mention that the power supply was enough. The system is 3 days old and seems to be running fine, though I haven't run a stress test yet. I get 12,300 on 3dmark06 with the card and an e8400 @ 3.6.
The card idles at 53 and is at 63 at full load so I guess I have a little room to O.C. the card.
