ATX Power Supply for Modern Standby Systems

The KHACHIMO P2040G-N is an ATX power supply designed for PCs that rely on Modern Standby sleep states. Its 280 W rating suits compact or office-oriented builds where high peak draw is not required. The unit delivers 5 V, 12 V, 24 V and 48 V rails for varied component needs.

280 W Capacity with Gold Efficiency

At 280 W the supply handles mainstream CPUs, integrated graphics and a modest complement of drives without strain. Heavy discrete graphics cards or multi-drive arrays will exceed its headroom. The 80 PLUS Gold certification ensures high efficiency across typical loads, reducing waste heat and fan activity.

Zero RPM Fan Mode and LLC Topology

A Zero RPM mode stops the fan completely at low and medium loads, yielding near-silent operation during everyday tasks. Resonant LLC topology with DC-to-DC conversion supplies clean power, suppresses coil whine and supports deeper, more energy efficient sleep states.

Questions about this item

Will the 280W P2040G-N run Modern Standby on my older motherboard?

The unit is Modern Standby compatible, so it supports the fast wake-from-sleep states that newer boards request, provided your motherboard also implements the feature.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

At typical loads the fan will stay off in Zero RPM mode, and the system should run cooler with lower power draw — both are the normal signs that Gold-rated efficiency is being delivered.

Does the box include every cable I need for 5 V, 12 V, 24 V and 48 V outputs?

The power supply ships with its standard ATX cable set; any specialised leads for the 5 V, 12 V, 24 V or 48 V rails must be sourced separately if your build requires them.
