Full spec below...No Overclocking at all

But when i play games or benchmark software, so when pc is using high graphics, my new OCZ PSU make very high pitch sound. I have read in other forums this is could by the coils, and will not damage the psu / system. But i dont want that sound at all...

Or can anyone recommend a good psu, that is fairly quiet and can handle the system.
Thx

This is a very common issue, and if you search the forum you'll find lots of instances of this.

My system did this too when there was high FPS using a GTX280 and a HX620. However, over time it lessened massively and now is totally acceptable. Perhaps you could wait it out, as there's no guarantee a new PSU will sort this. I also couldn't tell if it was PSU or GFX very easily, but I'm thinking it was GFX because of the analogue power phases. These high pitched noises are very difficult to locate sometimes.
 
This will do the job nicely. Go for the HX series if you want modular cables.


Unrelated, but may I ask why no overclocking? You have a top-end overclocking motherboard and CPU, plus your cooler is good enough to allow you to hit 4GHz.

That PSU is very good, but there's nothing wrong with the one he has, and as you'll see in my post I had similar problems with a Corsair HX.

I think it's more an issue of the GFX-PSU pairing.

Hi, whine most commonly comes from inductors (coils), but can rarely come from capacitors if they're poor quality. This is due to the high switching frequency within a PC SMPS.

Hot glue could (and should) be used to stop coils whining, and the fact that your PSU left the factory with nothing to stop the coil whine is bad quality control.

I would ask for a replacement or a refund.
 
Gone back to my old OCZ PSU, and no High pitch noise. But fan is so much louder...got a 1000W PSU so i could upgrade my GPUs when nvidia bring out there new ones.

The coils thing has been said by others, but your right is bad quailty control, will get an RMA from them...If the replacement is the same, will get a refund.

NO overclocking, as i dont want to go down that route at the mo...

Just did a PSU config for my system via Coolermaster.

Says my spec i just need 564W, so i guess my 1000W is well overspeced. So i could go for a 700W or 850W.

What i want is a modular (cuts down the cables) and as quiet as possible, and whats all this "80 Bronse / Silver / Gold" they keep saying about PSU.

thx

The 80 bronze/silver/gold are the ratings of how efficent the power supply is... I would go with a HX850w which should be plenty for nvidias new cards or a HX1000 if you want to be sli'ing a few GTX3xx cards and also it will be ready for the next cards after that hopefully :P
