KHACHIMO 300W ATX Power Supply

The KHACHIMO 300W ATX power supply delivers Gold-rated efficiency for standard desktop builds and office refreshes. It supports Modern Standby for rapid wake-from-sleep and uses resonant LLC topology with DC-to-DC conversion for stable voltage regulation. The unit is new and intended for systems that do not require high-wattage overhead.

Capacity and headroom for typical workloads

At 300W rated output the unit comfortably handles integrated-graphics desktops, business productivity PCs and light home-office configurations. It runs out of headroom when a discrete graphics card or multiple storage drives push sustained load beyond the rated capacity. The fan stops completely at low and medium loads, keeping acoustics near zero during typical office tasks.

80 PLUS Gold certification decides fit

The 80 PLUS Gold badge guarantees high efficiency across the load range, lowering power draw, heat and noise compared with lower-rated units. If your build demands more than 300W continuous power, this supply is not the right part. Buyers needing higher wattage or modular cabling should look elsewhere.

Questions sur cet article

Will the 300W unit work with my older motherboard that still uses a 24-pin ATX and 4-pin CPU connector?

Yes, the PSU follows the ATX form factor and provides the standard 24-pin main and 4+4-pin CPU connectors used by legacy boards.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

At typical loads the fan stays off thanks to Zero RPM mode, and the system wakes from sleep almost instantly with Modern Standby support.

Which cables are permanently attached to the YM-2301H YH-5301C and what must I source separately?

The unit ships with fixed 24-pin ATX, 4+4-pin CPU and peripheral leads; any 6-pin or 8-pin PCIe cables are not included.
