Tagan BZ 700w whine under load

post #1 of 3
Thread Starter 
This nice fellow posted this in another thread

If it's more a whine/sequel than a buzzing, it's probably to do with the change in voltages needed for the card, my 460's whine at stock voltages during gaming (0.978), whine even louder upto 1.050v but don't make a noise above 1.050v when gaming.

Different amounts of voltages probably give off a slight noise at certain frequencies which can be heard, probably from a capacitor on the card.
My PSU whines when graphic card is used for gaming or just under load in FurMark, really noticeable whine, is it safe to bump the volt to 1.050v and see if the whine goes away under load or do you think my PSU is not handling the card.

Similar issue with previous card, 9800GTX+

Also, what are safe volts for my GTX 560

Thanks!

I think your PSU is plenty for that card, you could try increasing the voltage, but it might not help with the caps squealing.

Some PSUs do whine - it's the inductors inside that are vibrating (NOT capacitors!).

It doesn't mean the PSU is bad, it just means they're not very well insulated...if you open it up you'll probably notice hot glue blobbed onto certain components - if you do that to all the inductors it'll stop it.

Read this if you want to know more about it.
