350W ATX Power Supply

The KHACHIMO NV325H4B is a 350W ATX power supply designed for systems that require Modern Standby compatibility. It suits builders who need fast wake-from-sleep response and high efficiency in a standard form factor.

80 PLUS Gold efficiency and Zero RPM fan

80 PLUS Gold certification delivers high efficiency operation for lower power consumption, less noise, and cooler temperatures. Zero RPM Fan Mode stops the cooling fan entirely at low and medium loads for near-silent operation.

Resonant LLC topology with DC-to-DC conversion

Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine for quieter operation. It also enables use of more energy efficient sleep states during sustained workloads.

商品問答

How do I install the KHACHIMO NV325H4B in a standard ATX case and which step is often missed?

Mount the unit with the four screws, connect the 24-pin ATX and CPU power cables, then verify the power switch on the rear is set to on before first boot.

What maintenance will the 350W power supply need over its lifetime?

The Zero RPM Fan Mode keeps the fan off at low loads, so dust builds slowly; clean the intake grill with compressed air once a year and listen for bearing noise that would signal a fan replacement.

Which limit appears first when the NV325H4B runs at full 350W continuously?

The 80 PLUS Gold efficiency target means heat rises steadily; sustained maximum output will hit the thermal protection threshold before the electrical limits, causing the unit to throttle or shut down.
