ATX 420W power supply for standard builds

This KHACHIMO YM-7421B is a new ATX power supply rated at 420W. It is intended for desktop systems that require a standard ATX form-factor unit. The supply has been test-worked by the supplier and is listed as good quality. First listed by the manufacturer in March 2024.

Suits basic office or home PCs.

This unit suits builders assembling or repairing entry-level desktops, office workstations or home PCs with modest power demands. It is not for systems with high-wattage graphics cards, multiple drives or overclocked processors that need more headroom. Buyers who need higher continuous output or modular cabling should look at a different model.

The deciding spec is the 420W ATX rating

The single specification that determines fit is the 420W ATX rating. If your build’s peak draw stays comfortably below this figure and your case accepts a standard ATX supply, the unit will work. If the system requires more power, this supply is not the right part.
