KHACHIMO 420W ATX power supply

This KHACHIMO unit delivers 420 watts through a standard ATX form factor. It is intended for desktop builders replacing an existing supply or assembling a modest office or home system. The unit has been tested as working and is supplied new.

Sustained load behaviour

Under continuous demand the supply maintains its rated 420 watt output within ATX specifications. It is not designed for builds that require 520 watt or 550 watt peaks, so high-end graphics cards or multi-drive arrays should be avoided.

商品問答

How loud does the YM-7421A get when it runs at 420W all day?

The unit is tested working and rated for 420W continuous output; typical ATX designs of this class use a temperature-controlled fan that stays quiet under normal loads.

What cables or connectors must my build already have for the SSG550M to power it?

It uses a standard ATX form factor with 24-pin main, 4/8-pin CPU and peripheral connectors, so your motherboard and drives need matching sockets.
