KHACHIMO PB500 500W ATX 12V Power Supply

The KHACHIMO PB500 is a 500W ATX 12V power supply built for standard desktop builds. It delivers 500 watts of continuous power with active PFC and operates on 50-60Hz mains input. This unit suits system integrators and home builders assembling office PCs or entry-level gaming rigs. Buyers who need higher wattage for multi-GPU configurations or workstation-class components should look elsewhere.

ATX 12V Interface Practical Limits

The ATX 12V form factor fits standard ATX cases and motherboards using the 24-pin main connector and 12V CPU connector. Active PFC corrects the power factor automatically across 50Hz and 60Hz supply frequencies. The 500W rating sets the ceiling for total system draw; exceeding it risks instability or shutdown. Builders requiring 12VHPWR for modern GPUs or EPS 8-pin for dual-CPU boards cannot use this supply.
