PowerStream Noise?

I was just overclocking my A64 3500+ and was stress testing it with Prime95 (Priority set to 10) and i kept hearing this faint digital-like noise emitting from my PC. I put my ear up to the back of my power supply and it seems to be coming from there. Its like a fast paced digital noise. It doesn't sound like its going to blow up or anything but it does sound a little weird. Do any of the rest of you PowerStream users notice this when the PC is under heavy load?

You can't really hear it unless you go and put your ear up to the back of the power supply and its hard to hear unless you put the PSU under load.
 
BTW, (off-topic) what you getting from your 3500. for grins after your p, I oc'd mine to 2.5 ghz at 1.65 volts and it has been prime stable for a while. Gotta say I love the OCZ Powerstream. That, PC P&C, and Fortron, are all I will ever use.
 
at least until your trying to power enough drives to brownout the local grid and keep them online 24\7
then you'll likely add a redundant Zippy Emacs to your list ;)

I havn't overclocked and stress tested much yet but at the moment i'm running 2.4Ghz with stock cooling on stock voltage.

And i know there are several PowerStream users here on HardOCP so why can't someone just run something like Prime95 and tell me if they can hear anything!

You probably wont be able to hear it unless you put your ear up to the exhaust on the power supply because its not very loud and my PC is fairly quiet.
 
Mine is fine. It runs STABLE. Putting my ear up to it produces nada. If there is digital noise it is SLIGHT at best, and I ran Prime for several hours when I checked. I think you are good to go man. I have to say that I love the OCZ's thus far. I am getting a second 600 watter as well. BTW, Ice Czar, woiuld a 600 watter run a dual opteron system like in your sig pretty well? Just wondering as i am thinking about venturing into that arena.
 
very likely but you need to get one with the 8 pin (2x4) auxillary +12V mobo connector
which would make it EPS12V compatible (and work up your numbers)
like the PCP&C in my sig


a truely compliant EPS12V would have 3 to 4 rails
Enermax offers a few in the ATX-PS\2 form factor
PCP&C has an EATX 850 in the works that is compliant
Topower actually makes a truely compliant P6 Series supply but OCZ doesnt carry it
TOP-708P6 (the last two varients are respecively a common plane EPS12V w\ 3 rails and a split plane EPS12V with 4
considering OCZ vaunted claims at customer service these days, you could try to special order one
 
I’m still curious how you hear “digital” noise…….
 
Some people describe it as a cricket chirping noise that only fades or pauses when the cpu load changes. I think people notice it more when they have a quiet computer and they have a powersupply that is running close to it's full load.
