KHACHIMO Hipath3550 300W ATX PSU

The KHACHIMO Hipath3550 is a 300W ATX power supply built for standard desktop PCs. It carries 80 PLUS Gold certification and uses Resonant LLC topology with DC-to-DC conversion for clean, stable output. Modern Standby compatibility ensures fast wake times and improved low-load efficiency. This unit is new and ready for system integration.

Suits quiet, efficiency-focused builds

Builders who prioritise low noise will value the Zero RPM fan mode that stops the fan at low and medium loads. The Gold-rated design reduces waste heat and keeps temperatures down in compact cases. Systems needing more than 300W of continuous power should look at higher-capacity units instead. This PSU does not support loads beyond its rated output.

300W continuous power rating

The single figure that decides fit is the 300W maximum output listed on the label. If your CPU, GPU and drives together draw more than this under full load, the supply will not be adequate. Check your components' peak power requirements before choosing this model. No other specification overrides this hard limit.

Questions about this item

How do I install the Hipath3550 ATX power supply and which step is often missed?

Mount the unit in the case with four screws, connect the 24-pin ATX and CPU power cables, then enable Modern Standby in the BIOS so the fast wake-from-sleep feature actually works.

What maintenance will the Hipath3550 need over its life?

The Zero RPM fan stays off at low and medium loads, so dust buildup is minimal; just blow compressed air through the grille once a year if the fan ever spins up.

What limit appears first when the Hipath3550 runs at high load for a long time?

The 300 W continuous output ceiling is reached before thermals become an issue, so sustained draws above that will trigger over-current protection.
