Review on Songhe XH-M229 Benchtop Power Board - ATX Power Supply Breakout Adapter for Desktop Computer Chassis - 24 Pin ATX Transfer Board with 12V, 5V, and 3.3V Outputs - Pack of 2 by Michael Crossman

Reasonable price. Fuse holders are cheap but sufficient. Compulsory contributions are bad. You can get them to work, but don't count on them. (They turned out to be worse than I expected even after reading other reviews.) Good soldering. The width of the PCB traces is around 5mm for 3.3V and 12V and 5mm + 3mm for 5V so they should be able to handle a reasonable amount of current. Mine comes with four 25A250V fuses, so you'll probably want to replace them with something suitable for your application. It's cheaper than a 24-pin ATX power cable extension, which I'd take apart for something like this, so I'd get that again.
