The power supply arrived today, but it got misdelivered due to the address being one digit off. However, I got the package. 😏

The mainboard and RAM were delivered a few days prior, so the only thing needed is a CPU.

Power supply test:
* basic power on with no load. Short green power-on wire to ground, and that is it. All voltages are on point.
* basic power good test. Connect power supply to motherboard and power it on through the board. Success.

No actual load test has been done, e.g. power good test but with a complete system instead of just a motherboard.
