Hi all,
It's a standard computer power supply - electrically ATX type, but in a size for a desktop (not tower) - which makes a cheap source difficult. Size is WxLxH = 120x155x85 mm.
The brand name is Pro-V Power, model MPT-251 (and MPT-301). It is made by Marcon.
The MPT-251 failed, so I replaced with MPT-301 which worked for 6 months followed by identical failure. I am NOT overloading it.
I feel almost CERTAIN the problem is dried out electrolytic capacitors (probably just one) - but there are so many and it is tight in there.
The next replacement I acquired has worked for over a year, but is horrible - noisy, also fan bearing noise at start-up, also horrific radio interference.
The symptoms are - when attempting to switch on, the CPU fan runs for a couple of seconds, then nothing.
If anybody could help with a SCHEMATIC or tips, that would be great.
Thanks in advance.
Jim
