495W ATX Gold Power Supply

This 495W ATX power supply carries 80 PLUS Gold certification for high-efficiency operation across typical loads. It uses a resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power while reducing coil whine. Modern Standby compatibility ensures extremely fast wake-from-sleep times and improved low-load efficiency. The unit is suited for system builders and upgraders who need reliable, efficient power for standard desktop configurations.

Suitable for efficiency-focused builds.

The Gold-rated design benefits users who prioritise lower power consumption, reduced noise, and cooler running temperatures in everyday workloads. Zero RPM fan mode keeps the system near-silent at low and medium loads by stopping the fan entirely. Builders planning systems with power-hungry components or multi-GPU arrangements should look elsewhere, as the 495W rating limits headroom for such configurations. The unit fits standard ATX cases without requiring proprietary connectors.

495W output decides fit

The single specification that determines whether this is the right part is the 495W rated output. Match this figure against the total power draw of your planned components to confirm adequate headroom. If your build requires more power, this unit will not suffice; if your estimated draw sits comfortably below this level, the Gold efficiency and quiet operation become clear advantages. No other specification in the data overrides this capacity limit.

Questions about this item

Which cables come attached to the KHACHIMO 495W ATX unit?

The power supply is an ATX form-factor unit with a fixed 24-pin main connector and the necessary EPS, PCIe and peripheral leads for a standard desktop build.

How do I decide between the 520, 620, 720 and 730 variants listed in the title?

Those numbers are manufacturer part references — 520, 620, 720, 730, 9338 and 33 — not wattage options; every variant delivers the same 495 W rated output.

What does the 80 PLUS Gold rating mean for daily use?

It certifies at least 80 % efficiency at typical loads, so the unit wastes less electricity, runs cooler and allows the Zero RPM fan mode to stay silent longer.
