Wattage Help!!!

[o00JONESY00o]

This is my first build and I need to know if a 550W True Power Trio will be powerful enough to support this system, and also when I have the money to buy a second VGA if it will still be powerful enough to support me:

XG Box Viper 2 Case
Intel Core 2 Duo E6600
ARCTIC COOLING Freezer 7 Pro 92mm CPU Cooler
ASUS P5N-E SLI Mobo
MSI NX7900GS-T2D512E-OC GeForce 7900GS 512MB Overclock Edition VGA
Creative Sound Blaster X-Fi Xtreme Audio 7.1 Sound Card
Western Digital Caviar SE16 WD2500KS 250GB 7200 RPM 16MB Cache SATA 3.0Gb-s Hard Drive
LITE-ON Black 20X DVD+R 8X DVD+RW 8X DVD+R DL 20X DVD-R 6X DVD-RW 12X DVD-RAM 16X DVD-ROM 48X CD-R 32X CD-RW 48X CD-ROM 2MB Cache SATA DVD Burner with LightScribe
LITE-ON Black 16X DVD-ROM 48X CD-ROM SATA DVD-ROM Drive Model SHD-16S1S-05
Sony Floppy Drive (I know its not neccessary but only way to load Raid drivers I heard, plus if I feel like goin' old school and playing some DOS games it will be helpful)

Go to this web page to figure out which power supply is certified for SLi duty with two 7900GSs. Bookmark the page for future reference.

um... i think i might have made a mistake since mine is not a 7900gtx i went with the other section and it was under that but in the 7900gtx it only supports 650W. i went ahead and just purchased the PSU was that a bad move, i'm not sure if the 7900GTX or GS use the same power. HELP!!!!!!!!!!

You're fine with the Antec 550 watt. It's listed as good for all other SLi setups. The higher watt power supplies are required for the real power hungry video cards...the 7900GS isn't one of them.

alright thanks so much i almost crapped my self when i saw the gtx menu cuz i had just boughten the psu

[doubledragon5]

I would go with a Segate 7200.10 over the WD. Most cases which come with a psu is not always of good quailty I would suggest one from this list..

DD5, looks like the original poster has already bought the Antec TP Trio 550w. These units are Seasonic made, and as such are of high quality. It's a good choice for that system.

[doubledragon5]

Thanks Freakitchen I don't know how I missed that..

[o00JONESY00o]

well it turns out that the auction for the PSU was a fake listing but I found an Ultra X-Finity 600W and purchased that because I saw in a Hiper HPU review on newegg a guy raving about how the Hiper sucked and that you should go with Ultra. And thanks for the advice doubledragon5 but I will not be using it because the WD has a larger cache and it has a better newegg rating and also i am a very big WD guy. I know it sounds strange since this is my first BUILD but I have been upgrading PCs for a very long time and the only other drive I used was a Maxtor as my first replacement but I tried a WD after and they haven't let me down since. The only thing better about the Seagate is that it has scarcely faster seek write and latency timings. whew this is a long reply but thats all I wanted to say. But again I'm not throwing you down just replying, and thanks for the help.

You actually buy computer parts through auction?

You actually believe those reviews on Newegg??

Well, if you're a Western Digital guy you should be okay with the WD...haven't been hearing of too many problems with them lately.

yeah i've been having some pretty good luck with auctions lately. and no i do not always believe the reviews on newegg i only believe the ones that i know arent from noobs because the peeps actually know what they are talking about.

[Mr.Ferrari]

I would not trust the ultra long term with the two 7900GS cards.

[freakitchen]

Me neither. I have a Hiper unit powering my main system at the moment - I'd put it in the same tier of quality as the Ultra you purchased - not junk but not brilliant either. Like your Ultra, mine has a high wattage rating (580w), yet I wouldn't be too happy if my system was drawing much more than, say, 450-500w from it. Lower quality units just don't have the ability to put out consistently clean power at the very top of their rated ability. An SLI configuration could/will push the draw into these higher levels. Since you've bought it, my advise would be to use it without too much concern, but replace it if you go SLI.

[o00JONESY00o]

i will be going sli, butnot for about a month or so. i've got other expenses at the moment that need to be taken care of
