Will this 600 watt power supply have enough juice?

[Margo1]

I am now researching and planning a new gaming machine. It will probably contain 2 gtx's, 3 raptors, 680i mb, Intel Core 2 Extreme QX9650 , 4 gig ram, 2 dvd drives, external HD tv turner, 24 inch Dell monitor, and audigy 2 sound card with 5.1 logitech speakers. I have a used 600 watt power supply I would like to use for this. Do you think this is enough power? Thank you.

That's a damn nice build but I HIGHLY doubt it.

Probably not but it would help if you would list the PSU brand and model. If its not a newer model 600W and not from a good name brand then it won't handle that kind of a system.

600w might handle it, but it would be pushing it and a single large 12v rail would be highly recommended. As you can see : here this is what Jonnyguru has to say about a roughly similar build as yours:

8800 GTX 768MB x 2 SLI bridge on build 1
Total: 527W DC.
Total +12V2: 7.2A
Total +12V1: 30.2A

Comments:

It's interesting to see the power consumption via the 8-pin EPS12V connector gradually go down with each set of cards. Going from the 6800 to 7950, we apparently unleashed a GPU bottleneck. But now it seems as if we're seeing a CPU bottleneck. Once again, a decent 600W, as long as it doesn't have two +12V rails, is going to be adequate."

So a decent 600w unit, with a single large 12v rail. Or you'll need a 700w PSU, with 2-4 12v rails. BUT, I strongly urge you to reconsider your build. You've obviously got money to burn, but you also want the fastest money can buy, right ? Well, wouldn't it SUCK to see a new 8800gts 512 or 1024mb come out in 30 days, which beats the 8800gtx HANDS down, consumes less energy, and will probably cost 400$, or at least less then the 8800gtx costs now? Besides, 680i mobo's suck for qauds, can they even handle Penryn btw ?

Anyways, yeah, hold of your purchase, I think I saw nvidia having trouble with the 780 chipsets, but if they do come out soon, you will have a better mobo to run that qx9650, and one that does SLI as well. And waiting 30 days, till 3 december, for the new 8800gts's would definately be worth it.

Oh, and last but not least, you do realize that some 750gb HD's, that cost roughly the same as a 150gb raptor, are often equally fast in game loading times, or even faster? Check this thread out: http://forums.anandtech.com/me...=2112949&enterthread=y

Heck, in 1 month I hope to be seeing the samsung formula 1 HD's and seagate's new 7200.11 drives with 500gb and more, on a single platter.

Jup jup, if you are interested in high-end, and got to money to back it up, then it sure would be worth it to wait one month.

Oh yes, I had planned on waiting a little bit. The video card I quoted was for reference only. The HDs, Tv tuner, monitor, sound card and speakers are used and were given to me. I am thinking of a cooler master 830 case with a 1000 watt power supply. Thanks for the friendly response.

1000w is overkill. Pretty much any 700/800w unit will power anything you throw at it, unless your going dual socket xeons or whatever ... Here´s a good list of PSU´s that are top notch: http://www.jonnyguru.net/forums/showthread.php?t=103

Wow. Nice link on power supplies. Thank you.
