Compact 1U ATX Power Supply

This 250 watt unit fits the 1U form factor and delivers standard ATX power for small-chassis builds and replacement scenarios. It targets system integrators and home-lab owners who need reliable output in a slim enclosure.

250 Watt Capacity with Gold Efficiency

Rated at 250 watts and certified 80 PLUS Gold, the supply handles typical low-power CPUs, integrated graphics and a handful of drives without strain. Heavy discrete graphics cards or multi-drive arrays will exceed its headroom.

Modern Standby and Zero-RPM Upgrade

Modern Standby compatibility and Zero RPM fan mode replace older units that lack fast sleep-wake or silent low-load operation. The jump is worthwhile when upgrading a noisy or inefficient legacy supply in a compact chassis.

  • 80 PLUS Gold efficiency cuts power draw and heat
  • Fan stays off at low loads for silent running

Questions about this item

Will the 250W unit power my older ATX motherboard and drives without adapters?

Yes, it follows the ATX standard and supplies 250W across the rails, so legacy boards and drives connect directly.

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

The fan stays off at low and medium loads thanks to Zero RPM mode, and the system wakes from sleep almost instantly with Modern Standby.

Does the box include modular cables or must I buy them separately?

The unit ships with fixed ATX cables attached; no extra cables are required for a standard build.
