1U 450W ATX power supply for compact systems

The KHACHIMO FLX450-50HUA delivers 450 watts of continuous power in a 1U form factor designed for rackmount and small-form-factor builds. It fits standard ATX mounting points while occupying minimal vertical space. System integrators and IT professionals gain a reliable unit for dense deployments where height is restricted.

80 PLUS Gold efficiency with headroom

Gold certification means the unit runs efficiently across typical loads, reducing waste heat and fan noise. The 450 W ceiling comfortably powers mainstream CPUs, single GPUs and multiple drives. Builds demanding sustained loads above this level or multiple high-end graphics cards will exceed the available headroom.

Resonant LLC topology with DC-to-DC conversion

This architecture provides tight voltage regulation and low ripple across all rails, supporting modern sleep states and Modern Standby wake times. The Zero RPM fan mode stops the fan entirely at low and medium loads for silent operation. Buyers needing modular cables or a longer ATX connector reach should verify compatibility before purchase.
