300W ATX power supply for basic builds

The KHACHIMO PSR300-12A delivers 300 watts through an ATX form factor. It is suited to office PCs and low-power systems that do not demand high-wattage components. The unit has been tested working and is sold new.

Single 12V rail at 300W total

The 12 volt rail supplies the full 300W rating, which determines whether the unit can support the installed CPU and graphics card. Builders needing more power for discrete GPUs or multi-drive arrays should select a higher-capacity model.

Questions about this item

What does the 300W rating mean once the PSU is installed in a PC?

The 300W rating is the maximum continuous power the unit can deliver to all rails combined; your build should draw less than this under full load.

What does the ATX form factor cap in practice?

ATX defines the physical dimensions and the standard 24-pin main connector, so it fits any ATX case and motherboard that follow the same specification.
