High-efficiency 1200W ATX power supply

The KHACHIMO PSR1200-D is an ATX power supply rated at 1200W with 80 PLUS Gold certification. It targets builders who need reliable, efficient delivery for high-performance systems. Modern Standby compatibility ensures extremely fast wake-from-sleep times and better low-load efficiency. The unit is new and designed for standard ATX installations.

Upgrading from lower-efficiency

This supply replaces older units that lack 80 PLUS Gold efficiency or Modern Standby support, reducing power consumption, noise, and operating temperatures. The jump is worthwhile when a build demands cleaner power for stable overclocks or when silent operation at idle is a priority. Resonant LLC topology with DC-to-DC conversion reduces coil whine and enables more energy-efficient sleep states.

Integrates into ATX builds

The power supply fits ATX chassis layouts and provides the connectors expected for modern components. Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation, freeing the acoustic budget for other components. Clean, consistent output from the resonant LLC design supports stable voltage under varying loads. Ensure the case accommodates a standard ATX PSU form factor.

Questions about this item

Does the PSR1200-D fit a standard ATX case?

Yes, the unit follows the ATX form factor so it mounts in any case designed for ATX power supplies using the four rear mounting screws.

What is the common mistake when installing the modular cables on this PSR1200-D?

Builders often leave the 24-pin motherboard or 8-pin CPU cables partially unseated; push each connector until the latch clicks to avoid no-post or instability.

When should the 120 mm cooling fan be cleaned or replaced on the PSR1200-D?

Clean dust from the fan grill every six to twelve months; replace the fan only if bearing noise appears after years of use.
