[RFI] Noisy computer Power Supply

[Roger (K8RI)]

I have 4 Corsair HX850 (850W) supplies (certified modular)
1 is less than 3 feet and 1 is about 4 feet from the HF station in the 
den.  The HF Rig FTDX 5000MP is on the same network. The two CPUs are 
running between 4.4 and 5 GHz. The 5 GHz is new so no real experience 
except for on and off.  I have a similar setup in the shop but with an 
Icom 756 Pro and a Yaesu 1000 MK-V

The 75 and 160 antennas are within 60 feet of the network, except the 
Network and coax lines run parallel and about 3' apart.

I don't detect a bit of noise from the computers.  These are high 
performance gaming computers that are also used for business and 
programming with 4 and 8 core CPUs. Each has roughly 6 HDs. I say 
roughly as they get moved around a lot. It's easier to pull a drive 
caddy than to move a loaded, full size, steel tower case.
