I had a brumby’s outlet call, as their CCTV PC (with a feed from 4 cameras) would only run a few hours, before switching off.
This sounded like a typical power supply failure, except the PC was difficult to reach, and was coated in a black, soot like muck.
It looked like a slimline “HP” style PC, but it was totally black, and had a bright yellow “lookc” name on it.
After opening it up, I could see it had a non-standard power supply 🙁
I also see that the CPU heatsink and fan are covered in the black muck. Since its a pentium 4 CPU, I figure it needs good airflow (regardless of the state of the PSU), so I give them a good clean.
After that I test the PSU: I short the “start delivering power” pins, and the fan won’t start (and no voltages from any of the connectors).
So I make a note of the PSU model number, and go back to the office to do some research.
It turns out I’m dealing with an AOpen H340a case, and a custom power supply.
I find the PSU model (fsp200-60SAV) is available at a few online stores, and I quickly settle on a unit from techbuy.
Delivery was quick, and I pop over and install the PSU. After that, everything works well.
