300W ATX Power Supply

The KHACHIMO AT P8P9P10 delivers 300W of continuous power for standard desktop builds and replacement scenarios. Its ATX form factor fits typical chassis layouts without proprietary mounting requirements. The unit targets system integrators and upgraders who need reliable baseline output for office or home workloads.

80 PLUS Gold Efficiency and Headroom

Certified 80 PLUS Gold, the supply maintains high efficiency across typical loads, reducing waste heat and electricity draw. At 300W maximum output it comfortably handles mainstream CPUs, integrated graphics and modest discrete cards; sustained loads above this rating will exceed its capacity and trigger protection.

Modern Standby and Zero RPM Fan

Modern Standby compatibility enables rapid wake-from-sleep transitions and deeper low-power states supported by current platforms. Zero RPM mode stops the fan entirely at low and medium loads for silent operation. Resonant LLC topology with DC-to-DC conversion supplies clean voltage rails and minimises coil whine during daily use.

Questions about this item

Will this 300W ATX unit fit and power my older motherboard that uses a 20-pin main connector and a 4-pin CPU plug?

The supply follows the ATX form factor with a 24-pin main connector that splits to 20+4 and a 4+4-pin CPU lead, so it will connect to legacy 20-pin and 4-pin headers without adapters.

How can I verify the Zero RPM fan mode is actually engaging after I build the system?

With the PC idling at low load the fan should stay completely still; you can confirm by watching the fan through the grille or listening for silence while the 80 PLUS Gold efficiency keeps internal temperatures low.

Which cables come attached to the PSU and what extra leads might I need for a graphics card?

The unit ships with fixed 24-pin ATX, 4+4-pin CPU and peripheral cables; if your GPU requires a 6+2-pin PCIe connector you will need to purchase a compatible adapter or cable set separately.
