KHACHIMO 300W ATX Power Supply P1A-6300P

SKU CH-7HQQ-121FQ

An 80 PLUS Gold ATX unit delivering 300 W with Zero RPM fan mode and Modern Standby support for quiet, efficient power

  • Product typeATX
  • Faster wake-from-sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Fan stops completely at low loads for silent running
  • Resonant LLC plus DC-to-DC delivers clean, stable power
  • 300 W ATX output in a compact 1U form factor

Compact 300W ATX supply for small-form-factor builds

This 300W ATX unit fits 1U and other space-constrained chassis while delivering enough power for entry-level desktops or embedded systems. The 80 PLUS Gold rating keeps heat and electricity use low during everyday workloads.

300W continuous output for modest component lists

The 300W ceiling determines whether the supply can handle your CPU and GPU combination; high-end graphics cards or multi-drive arrays will exceed this limit. Builders planning stronger parts should select a higher-wattage model.

Modern Standby and Zero RPM fan mode for quiet sleep

Modern Standby compatibility enables near-instant wake and better efficiency at idle, while the Zero RPM mode stops the fan completely under light loads. Resonant LLC topology with DC-to-DC conversion reduces coil whine and supports deeper sleep states.

Questions about this item

What does the 300W rating mean for a typical desktop build?

It delivers up to 300 watts of continuous power, enough for entry-level systems with integrated graphics or a low-power dedicated GPU.

How does the 80 PLUS Gold certification affect daily use?

It guarantees at least 80 percent efficiency at typical loads, reducing electricity draw, heat output and fan noise.

Will this 1U ATX unit fit in a standard tower case?

The 1U form factor is designed for rackmount or slim chassis; it will not align with standard ATX mounting points in a full-size tower.
