Brand New AntecTPN starting to whine

post #1 of 6
Thread Starter 

My TX-750 started to die last week and I replaced it with a brand new Antec TPN 650w from newegg.

The first couple of days it was completely silent even under full load just like my TX750 was.

Now it's starting to make a high pitch sound kind of like if you were traveling in an airplane.

It's similar in pitch to the video below but not as loud (...yet. I'm afraid that it's going to sound like that CM 1100w if I keep folding on the Antec TPN 650w 24/7...)

What do you guys think?

That's most likely coil whine. If you can't stand it, you can RMA the unit.

As Tator said, you can RMA if it bothers you. Coil whine doesn't indicate a faulty unit, though.

yeah, that's what I have. I narrowed it down to when My 8800GT is working Physx or Folding. I've been too lazy to get the modular cable to hook it up to a different 12v rail.

Check that your gpus ain't sharing a strand with any devices. Make sure their on their own strand and only the gpu on that strand. Move all the other devices to THE other. This solved similar issues a couple of times. You can give it a try.
