For noise suppression, you want 470uF to 1000uF, and possibly more if you have a really noisy supply rail. Those forests of high-value capacitors on computer motherboards are there to reduce the noise coming from the power supply.acanessa wrote:2) Used the Cap on the board. This apparently had no effect, but I think the noise from the PSU was too much for the cap, that's why perhaps? I used a 10uF 25v and a 100uF 25v.
Glad to hear running the power through a UPS solved the problem. Happy hacking!
