280W ATX Power Supply for Modern Standby PCs

This KHACHIMO DPS-280HB A delivers 280 watts of continuous power in a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency across typical loads. Modern Standby compatibility ensures extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine.

Suitable for office and home systems needing

Builders assembling or repairing PCs that require Modern Standby support and quiet low-load operation will benefit from the Zero RPM fan mode and Gold-rated efficiency. Systems demanding power output above 280 watts, multiple high-end GPU connectors, or redundant power modules should look at higher-capacity units designed for those workloads.

280W maximum output defines the usable hardware

The 280 watt rating sets the hard limit for total system power draw, determining which processors, graphics cards and drive counts can be supported. Exceeding this figure will cause instability or shutdown, so the build must stay within the rated capacity.

Vragen over dit artikel

How do I install the KHACHIMO DPS-280HB A 280W ATX power supply and what 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 or replacement will this power supply need later?

The 80 PLUS Gold efficiency and Zero RPM Fan Mode reduce dust buildup, but the fan bearing will eventually wear out and the unit should be replaced if coil whine appears or voltages drift out of spec.

What limit appears first when the KHACHIMO DPS-280HB A runs under sustained load?

The 280 W maximum output is the hard ceiling; once total system draw reaches that level the over-current protection will shut the unit down to prevent damage.
