New to these forums and just want to say thanks in advance to anyone who takes the time to read this
I put together a new rig recently and it's running great with the exception of the bad luck I've had with some PSU's. I started out with this OCZ Fatal1ty 750W PSU
which had pretty annoying coil whine when under load during games. I exchanged it for another thinking it was a defect in that particular PSU only to have the exact same problem with the replacement.
Finally I decided to pop in my old XIGMATEK PSU
that I had in my old rig which had never whined for the 3 years I've had it, and now it's started to emit an annoying pulsing whine that making it hard to concentrate while using my computer. Difference is with this one it whines only when it's NOT under load. It seems to start just AFTER I've done some gaming or after a lengthy period of light use (internet browsing). It produces a whine that pulses on and off with seemingly no correlation to what I'm doing. The computer could just be idling or I could be surfing the internet and it will just whine and whine and whine.
Sooo to get to the point. Could I have some sort of combination of hardware that's going to cause any PSU I buy to whine? I'm hoping not considering the whine I've experienced with each PSU has occurred under different loads and didn't have the same pitch. Thing is, I REALLY hate having to change out my PSU as it takes me forever to route cables to my liking, and I REALLY don't want to purchase another PSU only to have the same problem again, but my hate of the whine is strong enough that I would rather switch it out again if I can be be pretty certain I'm not going to have the same problems. I've seen pretty good reviews for both this 650W
Corsair PSUs. Would anyone recommend those or do I need to cough up more cash and go with the AX series? I'd prefer to save money if I can but I also really really really don't want any more coil whine.
I'd like to buy it asap if I'm going to because newegg has a good price on Corsair's right now. If anyone out there has a similar system and has a PSU that they're happy with I'd really appreciate any other suggestions as well! Only thing that is a must for me is that's it's modular. Thanks to anyone who can help
