KHACHIMO PS-6301-07 300W ATX power supply

300W ATX power supply for modern standby PCs

The KHACHIMO PS-6301-07 delivers 300 watts of continuous power in a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency across typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. This unit suits builders assembling or refreshing office and home systems that prioritise quiet, efficient operation.

Verify ATX fit and PCIe 6+8-pin GPU power needs

Confirm the case accepts a standard ATX power supply and that the motherboard uses a 24-pin main connector plus a 4-pin or 8-pin CPU connector. The unit provides one PCIe 6+8-pin connector for graphics cards requiring that configuration. Check the graphics card power specification before ordering to ensure the single connector meets its demand. Cable routing space behind the motherboard tray should also be reviewed.

Gold efficiency and zero RPM fan under sustained

At typical workloads the 80 PLUS Gold rating keeps losses low, reducing heat output and allowing the Zero RPM fan mode to stay active longer. The resonant LLC topology with DC-to-DC conversion maintains tight voltage regulation during extended sessions, limiting coil whine. Under continuous high load the fan engages to maintain safe temperatures while the topology sustains clean power delivery.
