ATX 420W power supply for standard builds

The KHACHIMO YM-7421D is a new ATX power supply rated at 420W. It suits desktop systems that require a standard form-factor unit for everyday computing tasks. The unit has been tested and confirmed working before dispatch.

Sustained delivery at rated wattage

Under continuous load the supply maintains its 420W output without relying on short-term peak ratings. It is not intended for configurations that demand higher sustained power such as multi-GPU setups or workstations with many drives. The 3Y SSG520 and SSG550 references indicate compatible replacement applications.

商品問答

How much heat does the 420W YM-7421D produce during all-day operation?

The unit is tested working at 420W output, so its heat output will scale with the actual load your system draws rather than the maximum rating.

Which existing connectors must my build already have to use this ATX power supply?

It follows the ATX form factor, so your case and motherboard need the matching ATX mounting holes and a 24-pin main power socket.
