Is it bad when

[Vediovus]

I can make the high pitched whine coming from my probably overloaded PSU change tones by pausing the gpu client or closing the smp client? Probably time to pull the trigger on that 550w Corsair I've been eyeing.

Shut it down NOW and get a new power supply before it takes out your motherboard/CPU and/or your video card

You say that like you've never fried hardware for folding.
Burn baby burn.

What is your current system spec?

X3 8450@2.55, 8800GT, 2gb ram on a crappy ecs mobo. I used the psu calculator here for s&g and it came up at 308w. I know they aren't the most accurate things in the world, but still even if it was off by 30w, I'd still be under 80% capacity of my Earthwatts 430. Maybe its rma time.

I use an earthwatts 430 for a Q6600 @ 3GB, 4MB ram and a 8800GT-256MB with a GPU2 client and an SMP client. No problem and no noise.

I also use a Q6600 @ 3GHz, 8800GT-512MB and 8GB on a shuttle 400w 80plus.
Also GPU2 and SMP

The 430 is plenty for that config.
You may have a bad one.

Are you sure the sound is coming from you PSU?

I've got a 8800GT that as soon as I start up the folding program is whines (super high pitched and loud) the more I OC it the pitch goes higher.

I just moved it from my main case to the wifes to see if it was the PSU after reading your thread..... its not. I have an antec 430 in there and the same sound from my main rig.

Yeah I shut it down. Its a shame cause the bulk of my points come from it. What are the chances antec will advance ship me a new psu?

edit: After reading Kendraks post i went in the case, and it is the video card. I assumed PSU since I had one make a similar noise on me just before it blew up on me

Hmm I have a 380 EarthWatts running a Q6600 and 8800GT, no issues at all.

Probably pushing that PSU to its limits through... I estimated it at about 200 watts...
