Tonight while starting up a game my PSU started to let out a high pitched, almost tweeting noise. It only happens while the GPU is under load, loading the CPU doesn't produce this effect. I've tried to spray it with compressed air but it doens't seem to have much effect bar changing it from a tweet to more of a crackle like elctrical wires while it is raining. I'm hopinh I don't have to RMA it, would there be anything I could try before sending it off?

(a) Mice?

(b) Budgerigar?

(c) Cooling fan(s) bearings running short of lubricating oil?

I often have to lubricate the bearings on all my fans from time to time, to stop them squeaking, and slowing down!

You sure you are not hearing the Nvidia card?

Nvidia cards have a feature that sends out a high pitch alarm when they are not getting the power to them from the PSU...

That's a filter

Nope, it isn't the card. The sound is definately coming from the PSU. The sound and pitch changes, from a whine to a buzz and the light for the card is still indicating green.

That's a filter  :o a capacitor or a small link of one of the Doiodes or transistor What you might be hear is the 50-60 Hz of the AC power that comes from the normal electricity supply and something is vibrating because something stop working can be a zener diode too, If you don't want to Buy again HDD ,CPU, RAM, motherboard etc ,I suggest you to get a new one quicky..  

Alrot,

That was my first thought....main filter capacitor....... classic symptom in a PS.

When that goes all the way....... it could take the "whole machine" with it.

best,

By the worried inflections i'm putting into your words I'm assuming a possible warranty replacement is on the cards? Am I only in danger while i'm hearing the sounds coming from it or am in danger at any time th system is on?

If you have confirmed the noise is indeed coming from the PSU then the concerns expressed are very valid

Typically the type of noise described coming from a PSU is as Alex and John said and if it goes, it has the potential to take out everything in the system at the same time.

If it were me I would not use the system and get it replaced ASAP

OK I'l try to get onto warranty for it. Would anyone happen to know the warranty process for OCZ in Australia? There is nothing on their site and I really don't want to go through the retailer again after the debacle with my motherboard.

I've decided to leave this PSU and move onto a corsair Tx-850 http://corsair.com/products/tx/default.aspx It's single rail, 850w and non-modular. It is the only single rail PSU I can find in any of the retailers in my area. It seems that no one stocks PC Power & Cooling products in Australia except the online stores. Once it gets in I'm going to send my current one off for warranty with the usless mob I got it off and either hock it on eBay or keep it as a spare.

Sounds like a plan!

There isn't much of a point in keeping a defective (or dying) PSU around as a "spare" - is there?  Whatever secondary computer you put it in, you're risking the longevity of the computer and more grief.

Personally, I have no fondness for Corsair brand for PSUs.

I'm sending the old PSU off for warranty once I get my new one tomorrow. When it comes back all nice and new and fixed, then I'll keep it as a spare or hock it. I ahve heard good things about Antec and Thermaltake but I couldn't get a PSU from either brand that was non-modular and single rail in 850w.

OK, I understand now.  Regarding your requirements for the new PSU, any reason why you had to have a single rail only?

So.... Nick... a 36A single rail PSU is better than a 18A two-rail one? or is it the same?

I was confused with that some weeks ago, when trying to buy a PSU...
