ATX power supply for desktop builds

The KHACHIMO AD550M3.3-3C1 is a new ATX switching power supply rated at 550 watts. It is intended for standard desktop PCs that require a single 3.3 V rail with a 14 A current limit. The unit is supplied as a bare component for system integrators and DIY builders.

Straightforward ATX installation

Installation follows the standard ATX form factor and connector layout used in most tower cases. The main 24-pin and CPU power cables are fixed, so builders should plan routing paths before securing the unit. The most common issue is tight clearance behind the motherboard tray when bundling the non-modular cables.

Verify 3.3 V rail demand

Check that your motherboard and peripherals draw within the 14 A limit on the 3.3 V rail, as some high-density boards exceed this. Confirm the case accepts a standard depth ATX unit and that the fixed cable lengths reach your specific motherboard connector positions. The product was first listed in 2024, so current stock is recent production.
