I recently snatched Four of these nifty 1kW power supplies. They were all used but still working. Well I kinda damaged one of them but more on that later. Here are a few shots of these things. They’re pretty compact for that amount of power.

Here they are removed from their cases and ready some customization. To disassemble, remove all screws on the outside of the case except for the Eight that hold the fans in, remove the lid, remove the Four screws in the corners of the PCB. Pop out the mains connector and push in the LED. Then you need to pull the mains plug out of the case so you can guide the mains wires through the opening where the mains plug was. It’s a bit fiddly but It’ll come out. Just be patient and try not to rip off the caps and whatever else is soldered to the mains plug. The fans are in their own little subassembly which can be gentrly pried away from the rest of the board after unplugging the fans. Please not that the PSU will shutdown a few seconds after powerup when either of the fans isn’t connected and running.
