  • First listed by manufacturer in March 2024

ATX 800W desktop power supply

The KHACHIMO EPS-1280GA4 is an ATX power supply rated at 800W for standard desktop builds. It suits builders assembling new systems or replacing an existing unit with a fresh component. The unit was first listed by the manufacturer in March 2024 and ships in new condition.

Tested thermals and steady operation

Each unit is test working before it leaves the factory, confirming stable output under load. Good quality components help keep temperatures and noise at typical ATX levels during normal use. The 800W rating provides headroom for mainstream graphics cards and multi-core processors.

Direct replacement for older ATX units

This supply replaces a worn or lower-wattage ATX power supply in an existing chassis. The jump is worth it when the current unit cannot sustain the power draw of upgraded components. Builders needing modular cabling or efficiency certifications not mentioned here should verify those details separately.

Questions about this item

How do I install the EPS-1280GA4 and which step is often missed?

Secure the ATX unit to the case with its four mounting screws, connect the 24-pin motherboard and 8-pin EPS cables, then attach PCIe and peripheral power leads before closing the side panel.

What maintenance or replacement will this 800W supply need later?

The internal fan is the only moving part; clean dust from its intake every 12 months and replace the unit if voltages drift or the fan becomes noisy.

What limit appears first when the EPS-1280GA4 runs at full load for long periods?

Sustained 800W output raises internal temperature, so the thermal protection circuit will shut the unit down before any component exceeds its safe operating threshold.
