http://www.pcpowercooling.com/products/viewproduct.php?show=S36ATX
I really do not plan to OC. Besides whats in my sig, i have 3 80mm fans. As far as futur upgrades, I plan to get a 6800gt and a raptor 10k HD.

Hell yeah that can power it, why spend that much if you are not going to oc.
good question..... everyone on this site just recommends those to be the best psu. What should I get if im not going to OC?

Yes PC P&C is the best but if you're not overclocking then maybe Fortron BlueStorm should work well and save yourself money to invest in something else
any fortron psu. your setup will only be using ~120 watts maximum, any psu that isn't faulty will be able to power it. fortron just happens to be a cheap and extremely solid brand. they are also marketed under the name sparkle.
just make sure whatever you find has the right connectors for your motherboard (20-pin / 24-pin / 4-pin aux). if in doubt, ask around the forums for someone with the same model psu, or buy one that explicitly says/shows what it has.

120? I thought I would need 300+?
The one I linked only goes for $65. Maybe 70 shipped. But if I only need 120w, I can grab a SPI 300w for $35. If I were to spend anymore than that, I might aswell grab the pcp. Dont you think so?

well.. your cpu and vga card will draw about 50 watts each fully loaded, and apart from that you just have a hard drive (8 watts when reading/writing), ram (10 watts per stick) and motherboard chipset (10 watts or so). it's very, very difficult to get even an intel system to draw 300+ watts, with amd chips it's hard to break 200 watts.
computers just don't use that much power unless you have enormously greedy components in there, which most people don't have, even when overclocked.
note that i still wouldn't advise going bargain-basement, when you're dealing with your power source stick to name brands and margins of error. the only cheap psus i would consider are fortron/sparkle, seasonic or channel well.
a 300/350 watt fortron will do you just fine, so long as it has the right connectors for the motherboard. if you're looking to spend more on a psu, pcp&c does make sense as its name recognition will command a high resale value, should you want to move to something else in the future.
sounds good and really makes sense. I appreciate you replies. I future upgrades inclue 2x1gig sticks, 6800gt, and a raptor 10k HD. Should I still be able to get away with 300w? Also, I mentioned the SPI I can get for 35. (Here is a LINK (http://www.centralcomputers.com/itemdetail.asp?item=POWSPIA3002R) ) If this is good enough to support my rig and future upgrades, Ill pick it up tommorow, if not, im going to order the pcp for 70.

754 2800+ = 80 Watts
Video card = 42 Watts
512MB memory = 20 Watts
1 HDD= 25 Watts
CDRW = 30 Watts
USB device = 5 Watts per.
80/90/120mm Fan = 2-3 Watts per
Even conservatively you will need a 300 Watt PSU. yeha, I don't know where you got your numbers, but I would get at least a decent 400 watt PSU.
I just found this wattage calculator. Not bad for a rough guesstimate

Dawhip, I have been going off the same, as well as other sites. And I have always found my set up to be between 280-360 watts. So I always assumed the same. A good 350-400w psu will do. *oh man am I confused*
Ok, Im on my back up rig now. I need to get back up and running to WoW :p
I just dont want to buy the wrong PSU and be in the same boat Im in now in 3 mos.
Again, thx

well some revised figures...
- athlon 64 2800+ stock - 60 watts (http://www.xbitlabs.com/articles/cpu/display/athlon64-90nm_5.html)
- geforce fx5700 - 25 watts (http://www.xbitlabs.com/articles/video/display/ati-vs-nv-power_8.html)
- 1gb pc3200 memory - 15-20 watts
- hard drive - 20 watts spinning up at boot, 7-8 watts otherwise
- optical drive - 30 watts spinning up, 5 watts at boot
- nforce chipset - 10 watts
- misc. usb devices and fans - 10 watts
that's a maximum bootup draw of about 140 watts, actual load while in windows will never be that high unless he burns a cd, performs a defrag, primes and runs 3dmark all at the same time. those just aren't high-juice parts :shrug:
a couple current-ish systems got measured a while back with watt-meters to get an idea of current power draws, here's the results (http://silentpcreview.com/article28-page4.html):
athlon 64 3800+
k8tpro board
4 x 512mb pc4000 ram (2gb)
9800 pro vga
2 hard drives
max 147 watts
pentium 4 3.2ghz
d875pbzlk board
2 x 256mb pc3200 ram
9800xt vga
1 hard drive
1 optical drive
max 180 watts
