KHACHIMO H81 Q87 14Pin 310W ATX Power Supply

ATX 310 W PSU for H81/Q87 builds

This KHACHIMO ATX power supply delivers 310 W through a 14-pin connector designed for H81 and Q87 platforms. It targets system integrators and DIY builders who need a compact, efficient unit for business-class desktops or small-form-factor refreshes. Modern Standby support allows near-instant wake from sleep. The 80 PLUS Gold rating confirms high efficiency across typical loads.

14-pin connector limits motherboard choice

The unit uses a proprietary 14-pin main power connector instead of the standard 24-pin ATX layout, so it only fits boards wired for that pin-out such as certain H81 and Q87 OEM designs. Maximum continuous output is 310 W, which restricts the GPU and CPU combinations the supply can sustain. Zero RPM fan mode stops the fan at low and medium loads, but the fan will spin under heavier draw. No other cable counts or connector types are specified in the data.

Verify 14-pin main power header and case clearance

Before ordering, confirm the motherboard has a 14-pin ATX power header matching the supply’s pin-out; standard 24-pin boards will not work. Check that the chassis can accommodate a standard ATX-depth PSU and that total system draw stays within the 310 W rating. Ensure the AC inlet and power switch orientation suit the case cut-out. No mounting screws or adapter cables are mentioned in the supplied facts.
