1050W ATX power supply for LITEON 4090

This new KHACHIMO unit delivers 1050 watts through an ATX form factor built to fit the LITEON 4090 platform. It carries 80 PLUS Gold certification and uses resonant LLC topology with DC-to-DC conversion for clean power delivery. Modern Standby support enables extremely fast wake-from-sleep times and better low-load efficiency. A zero RPM fan mode stops the fan at low and medium loads for near-silent operation.

Suits builders replacing a LITEON 4090 PSU.

This supply suits builders who need a direct replacement for the LITEON 4090 chassis. Its ATX dimensions and connector layout match that platform. It will not fit proprietary small-form-factor cases or server racks that require different mounting points or cable lengths. Buyers using standard ATX motherboards outside the LITEON 4090 ecosystem should verify pin-out compatibility before purchase.

1050W output decides fit

The single specification that decides whether this is the right part is the 1050 watt rated output. Systems drawing sustained loads above that level will overload the unit. Builds with lower peak demands can use it, but the rating sets the hard ceiling for any configuration.
