Coil whine question - PSU replacement, same model?

[johnno]

Hi,

I have the PSU and system in my sig. All was running great until a few days ago when I noticed a high pitch noise coming from my box. The pitch changes with mouse movements, most noticeably in games, it does happen in Windows a bit but you have to get down and listen.

I've had a google around it it seems a fairly common issue, some live with it some don't. Fixes range from changing mouse smoothing, using V sync and changing bios power saving settings.

Regardless, as I have had this PSU for less than 28 days the vendor will pick up and refund me. My question is before I arrange for it to be collected, I need to buy its replacement. Should I just get the same PSU or should I go for another brand? The main requirement is for the PSU to be quiet, especially when not under load.

I will probably be staying with http://www.ebuyer.com/ and wanting to pay around the £70-80 mark, while avoiding Corsair (Due to excessive fan noise on the TX650 V2 that I have also had)

Cheers

Usually mouse whine sounds come out the speakers not the PSU. Does your mouse cord have a choke on it ? Usually it will be around the usb plug, a large lump in the cord. If not add one, they are easy to do and will clamp the interference at the point the core is attached.

It's definitely from the PSU. If I put V sync on it goes away.

You think those chokes will stop the PSU whine when it's under load?

It's the PSU. How about this one?

Yes, Magic Carpet I nearly got the Silent Pro before. Think I'll get the 700w version, gets some great reviews.

It's a lot worse in older games where the FPS are high, Like TF2??

Basically, yeah. Try running a benchmark like PerformanceTest v6.1 & v7. Pay attention to the 3D tests. The simpler tests give you like 2000 fps. I can definitely hear my card. This is normal.

For older games, I recommend V-Sync on.

2) That sound varies from barely audible to annoyingly loud. Depending on the card and power supply. I also bought a number of Corsair PSUs off eBuyer and got them either exchanged or returned/refunded. Just no luck.

Worst combo I had, a gigabyte card w/ Corsair VX450. That was something else. I also had an expensive Seasonic that produced worse whining than a cheaper HEC. Price is not everything.

Palit/Gainward is my fav video brand.
