KHACHIMO 300W ATX power supply 12Pin D15-300P1A

300W ATX PSU with 12-pin connector

The KHACHIMO D15-300P1A is a 300-watt ATX power supply designed for systems that require a compact 12-pin power connector. It carries 80 PLUS Gold certification, meaning it meets high efficiency targets across typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power while reducing coil whine.

Suitable for small-form-factor or OEM-style builds

This unit suits builders assembling compact desktops or replacing proprietary units that use a 12-pin main connector and demand Gold-level efficiency at 300 watts. The zero RPM fan mode keeps acoustics near silent at low and medium loads. It is not for systems needing higher continuous wattage, multiple PCIe power cables, or standard 24-pin ATX motherboard headers. Buyers who want modular cabling or server-grade redundancy should look elsewhere.

300 watts continuous with Gold headroom

At 300 watts the supply comfortably handles mainstream CPUs and mid-range graphics cards within its rated output. The Gold-rated platform provides efficiency headroom that lowers heat and fan speed during typical workloads. It runs out when a build demands more than 300 watts combined load or requires additional 6-pin or 8-pin PCIe connectors not present on this model. Peak demands above the rated figure will trigger protection shutdown.
