KHACHIMO 420W ATX Power Supply CP-1356R2

Power for Modern Standby Builds

The KHACHIMO CP-1356R2 is a 420W ATX power supply built for systems that use Modern Standby sleep states. Its 80 PLUS Gold certification delivers high efficiency across typical loads, reducing waste heat and electricity draw. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power rails for stable component operation. It suits office PCs and quiet home rigs that prioritise low idle consumption and fast wake times.

Check Connectors and Clearance First

Verify that your motherboard and graphics card power connectors match the cables supplied with this unit before ordering. Ensure the standard ATX form factor fits your chassis and that no oversized CPU cooler or drive cage blocks the PSU mounting area. Confirm the total system power draw stays within the 420W rating, especially if you plan a discrete GPU or multiple drives. The unit carries model references SSG520M and SSG550M alongside the CP-1356R2 code for cross-reference.

Sustained Load Behaviour

Under continuous load the 80 PLUS Gold platform maintains its rated efficiency, keeping internal temperatures lower than less certified units. The Zero RPM fan mode stays active at low and medium loads, so the fan only spins when thermal demand rises during prolonged heavy work. Resonant LLC topology with DC-to-DC conversion suppresses coil whine and holds voltage regulation steady over long sessions. This combination suits workloads that run for hours rather than short benchmark bursts.
