EVGA 9800gtx+ SC power requirements

[wickedsnow]

How much wattage (rms) should a PSU have a a evga 9800GTX+ SC model with an e7200 cpu @3ghz with 4 gigs of ram?

Basic HDD,burner,case, etc etc

I would prefer to only spend less then $60 us dollars. And no online shopping either.

www.centralcomptuers.com or www.frys.com only.

Thanks all!

475W or more, with a combined 12V current rating of 26A or more.
Two 6-pin PCI Express connectors.

I tried Frys but I didn't find anything suitable under $60.

This 550VX would be good, but it's $90.

PC Power & Cooling 500W $80

Compared to the Corsair 550VX, it has only 35A instead of 41A. It's still powerful enough for what you need, just less likely to be useful when you upgrade that 9800GTX+.

12V rail providing at least 13 amps. I'm running it off an 18 amp rail and it works completely fine. 550 watt antec PSU.

my POWER meter show 300-375 watts with games that dont support SLI

ANd 400-475 with games that support it.

OCed cpu, water cooled, 10 fans total. with a normal system youll end up using 350W on gaming. I agreed to go with a nice CORSAIR or PC P&C .

Thanks for all your input guys. I personally own only PC@powercooling myself, but my friend here just wants something powerful enough for a maximum of 1 e7200 (oced to death) 4 gigs of ram and 1 9800gtx+. never to be upgraded after that. (he's going to build a new rig in a year.)

All of you came up with great suggestions, but i'm trying to stay cheap. $70 would be the most i would spend considering his needs are small. i'm fairly certian any good quality 500w-550w would be fine for him, but finding a good one for cheap,... damn near impossable.

It would be easier if you were willing to order online. Some sites offer free shipping, at least on some products.

For example:
OCZ StealthXStream OCZ600SXS 600W (35A, 2 PCI-E connectors, $50 after rebate, free shipping)
http://www.newegg.com/Product/Product.aspx?Item=N82E16817341010

There's also the Corsair 650TX (52A) for $70 after rebate, free shipping too.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005

Compared to the StealthXStream, it's worth the extra $20 all right. It's higher quality, and it's very likely to be reusable later even with a high-end graphics card. It's overkill for the 9800GTX+, of course.

i agree aevm, Online would be best. but he's picking up the new card + PSU in 4 hours, the PSU he has now is some 230W dell POS.

Would any of the below $50 PSUs work fine?

The first one, CoolerMaster 550W, has the 2 PCI-E connectors you need. I cannot figure out if it's over 26A combined or not. It has 2 rails of max 16A each and they refuse to disclose the max combined amount between those rails.

The second one says two rails of 18A each and combined 30A. That's good, but it only has one PCI-E connector and you need two.

Basically, the first PSU might do the job, but I can't guarantee it. As far as quality goes, CoolerMaster has a bad reputation from past years but their newer models seem decent.

The EX 550 will work just fine. But you'll need the 2x4 pin molex to 6 pin pci-e adapter to feed the video card.

If it's the same thing as this,
http://www.newegg.com/Product/Product.aspx?Item=N82E16817171038&Tpk=Cooler Master Extreme 550W
then it should have 2 connectors and you don't need to buy an adapter.

Hmm, better to be safe than sorry. I think an additional $20 for quality and piece of mind is just what I need.

I'll just go with the PC@powercooling 500W for $80. Does this model also have there famous single rail?

google their website and check out the specs to see if it does have it. Internet and google search ftw.

Yes, one rail, 35A.
