KHACHIMO

KHACHIMO 520 320 330 280W power supply

SKU CH-8W9X-19QP6

An ATX power supply delivering 520 320 330 280W with 80 PLUS Gold efficiency, Modern Standby support and a Zero RPM fan mode for silent low-load operation

  • TypeATX
  • Modern Standby support gives extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency for lower power use, less noise and cooler temps
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine
  • ATX form factor fits standard desktop builds and enables energy-efficient sleep states

280W ATX Power Supply

The KHACHIMO 280W ATX power supply delivers efficient power for modern desktop builds. It carries 80 PLUS Gold certification for high efficiency and lower running costs. Modern Standby compatibility enables extremely fast wake-from-sleep times. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power output.

System builders wanting quiet.

Suits compact or office PCs where 280W meets the total component draw and silent running is valued. The Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation. Not for builds with high-end discrete graphics cards or multi-drive arrays that exceed the 280W limit. Buyers needing higher continuous output should consider larger capacity units.

80 PLUS Gold efficiency at 280W

This unit is rated 80 PLUS Gold, meaning it meets strict efficiency targets at typical loads. High efficiency reduces waste heat, lowers electricity consumption and helps keep system temperatures down. The resonant LLC topology with DC-to-DC conversion further supports stable voltage delivery and enables deeper sleep states. This certification is the key figure for judging whether the supply matches your efficiency and thermal goals.

Preguntas sobre este artículo

What does the 280 W headline figure mean once the unit is inside a real machine?

It is the maximum continuous power the supply can deliver across all rails while staying within its 80 PLUS Gold efficiency targets and thermal limits.

What interface standard does this supply use and what does it cap in practice?

The ATX form factor dictates the 24-pin main connector, CPU power plugs and peripheral leads, so the 280 W rating is the practical ceiling for any build using those connectors.

What does the unit physically need to fit or mount in a case?

As an ATX-type supply it uses the standard four-hole mounting pattern and external dimensions shared by virtually all mid-tower and larger chassis.
