Electrical Buzzing Noise

Hardware Hub GPU

I purchased an MSI GTX 780 Twin Frozr a few days ago and I’ve noticed it produces a buzzing noise when under load, such when gaming or running a benchmark. Is this normal? Or have I get a defective unit and should RMA it?

Thanks

My friends 750Ti does that, I wouldn't worry about it. Its called coil whine.

Thanks, I thought it could be coil whine or the capacitors vibrating, but I wasn't aware this was such a common flaw among new graphics cards.

They've been doing it for years-- I just suspect its more noticeable to us now because our systems are generally quieter.

Yeah, that's a good point I hadn't considered. Personally I love my Noctua  fans, so quiet!
