Value psu with high stability for heavy OCing

I'm real tight on money so I am wondering if there is a psu out there that is stable enough for a heavy ocer.

I also need some wattage because I'll soon be running a 6800gt with a bunch of other stuff.. I'm looking to spend 50-60 bucks..

System:
p4 3.0c @ 3.675 ghz 1.625vcore
ic7 max3
geil 1gb (512x2) pc4400 at 3.1v


I've browsed around newegg and read some reviews on a few psu's, but those things are totally wrong sometimes..

Thanks for any help guys..
 
well, the antec true 430 is 65$, and the forton 530 is 75, both very good psu's
 
What is your budget? Try checking the sticky, and if you have any more questions come back and post em
 
That's a bottom fan :p

Define heavy OC'er? I know a lot of people that are >2.6 amd'ers and >3.8 Intel'ers that don't like the Antec Truepower series, and would recommend instead a Fortron 530 (or if you can swing it 550)
 
LoL.. Damn I'm a noob.

I guess my cpu will enjoy that extra hot air blowing right on it though :D

Well, I call myself a heavy ocer (I don't really know if I am or not.. are there like requirments?) because I'm running my p4 3.0c @3.7ghz..

Right now my +12v line never reaches true 12v, and fluctuates from 11.0-11.8v.. That's not good. Also all my voltage settings for many of my componants like to fluctuate which causes unwanted instability.

I would like a psu that can supports my voltages and keep them steady.. And it would suck if my psu would decide to blow up on me :eek:
 
Acturally, the bottom fan pulls air off of your CPU and out helps it get out the back. :p

Or at least that's what mine would do (if my PSU was anywhere near my CPUs). My computer (AMD) doesn't hit 2.6GHz, but I'm a power hungry OC'er because I run a dual CPU rig @ 2.45GHz. :D

And that fluctuation is scarry, I don't know what I'd do if I felt that. My vcore fluctuates a bit, but I think that is a motherboard voltage regulator issue, seeing how much power my AthlonXP's are drawing... But my Vantec "Stealth" 520 is holding up nice and cool, although the rails were off a bit according to my old beaten up Fluke multimeter... Don't remember if it was high or low...
 
The psu I'm using is a generic brand 350w POS..

It came with my x-dreamer II case.. Is this fluctuation harming me right now? Anything I should do in the meantime while I wait to get a new one?

You guys think the fortron 530w would be a nice choice?

It ain't helping you....

well I know it's probably impractical but the less your machine is running the less chance it has to blow out

HELL YEA :p Thats a great psu.
 
Def have to agree with compro03 but let me stress something. That powmax dreamer case 350w psu is a notoriously (infamous) bad psu. I've seen it in destructive action and have read a couple dozen horror stories in the past few months. This is not a psu that goes silently, its the type that kills hardware with it.

When you check the numbers on the label, you wonder where they came up with "350 watts".
 
when you park an overclock right up against the edge of stability
that stability is often how well any transient load is dealt with by the PSU
which is why the serious overclockers avoid introducing seriously dynamic loads
(you wont see extraneous components and certainly not alot of drives)
and pop $200 for PCP&C PSUs (Turbo Cools)

with everything largely powered off the +12V rail these days
that is a prime concern, since there are alot more components dynamically altering their power draw

I just got a Fortron 530 for my brother's rig
and its a great supply for the money
and for what it is, but its still a single +12V rail ATX12V v1.3 PSU
a good one but still, while the transient response is likely well within the spec
its spec is listed at 5% not 1% like a PCP&C 510 (also a single +12V rail)

that may or maynot be an issue, greatly depends on the config and usage pattern
as well as the quality of the mobo's VRM scheme, and the overclock

the other ends of your power supply chain also count, get a UPS or other power conditioning
and hope the mobo has a high quality VRM scheme (Voltage Regulation Modual)

another factor is the AC Ripple, and while most decent supplies will meet the spec few exceed it
PCP&C Turbo Cool +3.3V, +5V, +12V = 10mV, +5VSB = 20mV
Fortron 530 +3.3V, +5V = 50mV, +12V = 120mV, +5VSB = 50mV (@ what the spec calls for)
