KHACHIMO 1200W ATX Power Supply

The KHACHIMO PS-4122-1 HA is a 1200W ATX power supply built for high-output desktop systems. It carries 80 PLUS Gold certification for efficient energy conversion and includes Modern Standby compatibility for rapid wake-from-sleep performance. Resonant LLC topology with DC-to-DC conversion delivers stable voltage regulation across all rails.

Suits silent-focused high-power builds.

This unit suits builders who need substantial headroom for multi-GPU configurations or intensive compute workloads while valuing quiet operation through its Zero RPM fan mode at low and medium loads. The design reduces coil whine for a cleaner acoustic profile. Buyers assembling compact or low-power systems that do not require this output level should look at lower-capacity alternatives.

1200W maximum output

The single specification that decides fit is the 1200W maximum output, which must match or exceed the total power draw of all installed components under peak load. This rating determines whether the unit can support the intended hardware configuration without instability. Verify the combined requirements of your CPU, graphics cards, storage and peripherals against this figure before purchase.

Questions sur cet article

What sustained load limit does the 1200W rating represent for this PS-4122-1 HA unit?

The 1200W rating is the maximum continuous power the supply can deliver across all rails under normal operating conditions.

How does the 80 PLUS Gold certification affect fan noise and heat output during all-day operation?

Gold-level efficiency reduces waste heat, allowing the Zero RPM fan mode to stay off longer at low and medium loads for near-silent running.

Which motherboard power connectors must already be present for this ATX supply to work?

A standard 24-pin ATX main connector plus the required 8-pin or 4+4-pin CPU power connector on the motherboard.
