I will never, ever recommend spending less money on a PS to save money. It's the heart of your system, if you're going to skimp out, do it someplace like the CD drive or something.

Antec TruePowerTrio 550W Power Supply
Alright, here's the best power supply for the money that i've found.
3 12Volt rails and i've heard that it's made by seasonic (don't quote me)
But it's a very powerful unit that is only $64.99 and free shipping!!

I frankly wouldn't spend big money on a psu. Mind you I'm a cheapie and basically bought the cheapest parts possible to build my C2D system (which o/c to 525FSB).
For my Pentium 805D I bought a case with 450w psu for $29 Canadian (about $25US from Cancomputer.com). It may not be fancy, but it has never missed a beat and works perfectly.
I wanted a better psu for my P5B/E6300 and bought a new Hec AcePower 420W for $25.10 in an E-Bay store auction. While 420w may seem anemic, it delivers 32Amps and has dual-rail 12v. It turns out to be a "heck" of a power supply! It has rave reviews, saying it's construction is similiar to premium top-end units, (except that it didn't use Japanese caps!) It weighs 7 lbs, has dual fans and a multitude of braided cables. So price or wattage does not always dictate value or performance.
The 450w ps that came with the case was essentially for free, as the case is pretty decent on its own. It may be worth trying one. If it works for awhile, Bob's your uncle! If not, no biggie, then buy your $149 psu.

I'll never understand why people buy thousands of dollars of components and then skimp on a power supply. Where's the logic in connecting thousands of dollars to a device built out of the lowest quality and lowest cost parts? Would you shop around for that "economy" 86 octane gasoline for a new 2007 Corvette Z06?
Ordering barrels of racing fuel for that same 2007 Corvette is just as silly.
I spent $99 for my Silencer470 from PCP&C and that was overkill. It runs my overclock C2D just fine with 4 HD's and all sorts of fans, etc and I'm sure it could handle a 8800GTX with no sweat. I wanted the Silencer610 at $159 but even if I bought that instead my system wouldn't run any better.
Besides, hopefully the videocard chip makers will get their act together and we won't need nuclear devices to power our systems in the future. :laugh:

replacing HW - out of your own pocket - because you "skimped" on a PS is stupid
you guys that are proclaiming you have a SLi system on a generic 350w PS are *lucky*
- of full of it

So I should be looking at the 12v rails more than the wattage rating right? Also, the 400w sparkle has a lot of positive reviews and looks like it has good rails.
The 400W Sparkle I linked to is essentially the same as the FSP 450W in the post above yours...however, it's a good deal cheaper even though both come from the same place (Sparkle Power and FSP are related).
Yes, the 12V rail is the most important consideration when buying a PSU. Most of the power draw on a modern system comes from the +12V rail (s).

If it results in transistors switching faster, then yes it does. But the increase may or may not matter at all.

The Trio is made by Seasonic. It doesn't really have 3 +12 V rails, which is fine enough.
Enhance's unit at the same price is a better buy.
I stand corrected.. I had to give it some thought.
Yes, transistors would be on more often, and therefore drawing more power. A 50% overclock could theoretically draw 50% more current..

Jonny's funny. Also, it's unbelievable that a unit called the Trio that claims to have 3 +12V rails really has only one!
Why? The Enhance is +16A+18A on the 12V, the FSP/Sparkle is +18A+18A. Is Enhance really that much better of a manufacturer than FSP?

Because Enhance makes a bit better psu's, and that FSP's ratings are max, not continuous, like the Enhance's outputs are.

I can't think of ANY $50 PSU I would recommend...
Um... Opinions are like... Well, you know the rest!
If I was you, I would listen to Nvidia's recommendations...
*edit*
Well, I'll be a !&^%@ SOB... Stop the presses!!!
I just found a Nvidia certified PSU for under 50 bones for your 8800GTS...
More info on the manufacturer's website...
Hey, it ain't the best PSU around... but, it's probably the best PSU for under 50 bucks!
Those are some very bad estimates. I happen to have a system with pretty much the parts you've listed above:
E6600 @ 3GHz (333*9) = 120W
Asus P5B = 50W
4GB (4*1GB) DDR2-833MHz (That's 16*4=64 ICs) = 120W
EVGA 8800 GTS ACS3 KO (588/1840) = 140W
WD Caviar SE16 250GB
Samsung T166 320GB
Samsung SH-S183A SATA DVD-RW
Soundblaster Audigy 4
USB WLAN
(50W combined for the last five rows above)
120+50+120+140+50 = 480W (according to your numbers)
Since I happen to own a power meter I have actually been able to measure the power consumption of the above system. The result? Max achievable power consumption was 260W. Since 15% of that turns into heat in the PSU, the actual power consumption of the parts in the machine is ~220W.
220W is pretty far from 480W. Where did you get your numbers from? Were they made up on the spot?
Yeah... it's like having 'headroom' on your amplifier. I always get one with a high rating then the intended speakers to be attached. If you know the difference PMPO and RMS, then you probably know the difference between a cheap and quality PSU.
I'll admit, in my 8086 proto that sitll works you'll find the original Fortron psu. but that's exactly what they represent, long time standard cheap pc parts. Fortron gets in done, and has a long history of doing so. But to me, that's all they'll ever be, and my tank doesn't run a honda civic engine if you you know what I mean.
units with active pfc generally aren't made cheaply. Here.

People spew so much "U NEED A MONSTER PSU TO POWER YOUR ACTUALLY NOT SO POWER HUNGRY SYSTEM" bull nowadays.
JohnnyGuru did a writeup on the Rosewill RP500-2 unit recently expecting the unit to explode in a shower of blue smoke. Instead it turned out a surprisingly good set of results, far exceeding expectations for performance particularly on the rock solid 12v rails (NO droop at full load in extreme heat conditions) and surprisingly low ripple. For $50 at Newegg plus freight this seems like one to keep on the short list of cheap PSU options.

Another sub $60 unit that JohnyGuru liked a lot was the Enhance 400 watt "80+" unit. Only 400 watt total output, but 80% efficiency, active PFC and 12v rail droop (or lack therof) and ripple performance similar to the Rosewill above.

Should this PSU be OK for my rig ?
Vitsuba 550W: 12V x 19A/12V x 20A/3.3V x 29A/5V x 50A.-
My rig: AMD64 FX60
ASUS AN8SLI Deluxe
1 GF 8800 GTS
3 HDDs PATA
2GB RAM
I want to be sure about OClocking chances with this PSU.-
Thanks

Hmm, I've never heard of Vitsuba - the specs on paper l but I couldn't find any english reviews that indicate it's real-world performance under ideal/load conditions. If I read the spanish-english translation right, that is an aPFC equipped unit for under $60 US?
Its a common brand here in Argentina, and never heard about problems with it, it is rated U$S 100 (here)
