Hello all, long time lurker, first time poster.
It's all been running swimmingly with my computer for 3/4 Years. I've decided to upgrade several components due to purchashing an Oculus Rift. Items have included:
1. Large CPU cooler for my old, trusty and now, overclocked (stable 4.0 Ghz @45 Celsius) Phenom ii X4 965
2. GTX 780 GPU.
3. New 600w Gaming (50 Amp single rail PSU).
I've soak tested everything and the Oculus will take everything I throw at it running 75FPS without breaking a sweat.
My problems began when I added the new PSU. My old (crappy) Artic Red 750w PSU was wailing like a banshee and cutting out on most modern Oculus stuff.
I went to the local PC place to get something more realistic to match the 780.
The long and short of it is that I ended up trying out 3 gaming PSU's. 700-800w versions from Cooler Master, Antec and Corsair. All of these gave me a significant problem, massive amplification of the computers internal working through my amplifier and speakers. It's got to the point that when I'm running games, the processor, ide, bus noise etc. is louder than the in-game audio.
My first thought was to unplug everything in the house, bar the PC and amplifier to check for earth leakage (dirty earth), to no avail.
If I use headphones, the noise goes away, suggesting a ground loop.
If I remove the earth lead from the PC power supply (I don't want to make this permanent for obvious reasons) the noise goes away.
Now here's the real pain in the a***. When I put my old, crappy 750W PSU back in, it's all as quiet as a morgue.
Why should, supposedly high end, quality PSU's give me this problem, when a £20 Far Eastern clunker provides me with no grounding issues whatsoever?
Many thanks in anticipation,
Chris.
