  • TypeATX
  • Fast wake-from-sleep with Modern Standby support
  • Lower power draw and cooler running via 80 PLUS Gold efficiency

  • Clean, stable power delivery through LLC resonant topology with DC-to-DC conversion
  • Compact 1U ATX form factor fits space-constrained builds

Compact 1U ATX power supply for small-form-factor

This 12 V unit delivers 270 W in a 1U chassis, making it suitable for thin servers or compact workstations that require standard ATX connectors in a shallow footprint. It is not intended for full-size towers or multi-GPU configurations that demand higher wattage.

Sustained-load behaviour

The 80 PLUS Gold certification means the supply maintains high efficiency during continuous operation, reducing waste heat and keeping internal temperatures lower. Zero RPM mode stops the fan completely at low and medium loads, so extended idle or light workloads run virtually silently.

Straightforward ATX installation

Standard ATX pin-out ensures compatibility with common motherboards, but the short cables typical of 1U designs can make routing difficult in deeper cases. Builders should verify connector lengths before committing to a layout that places the PSU far from the main power sockets.

  • Lower power draw and cooler running via 80 PLUS Gold efficiency
  • Near-silent operation as fan stops at low loads

Questions about this item

How quiet is the 270W unit when it runs 24/7?

The Zero RPM Fan Mode stops the fan completely at low and medium loads, while 80 PLUS Gold efficiency and resonant LLC topology reduce heat and coil whine for near-silent operation.

Which cables or connectors must I already have to install this 1U ATX supply?

The unit uses a standard ATX form factor, so it fits existing ATX mounting points and connects to a typical 24-pin motherboard header plus the usual CPU and peripheral cables you already own.

Will this 12V 270W supply work reliably with an older motherboard that lacks Modern Standby?

Yes, Modern Standby compatibility is backward compatible; the supply delivers clean DC-to-DC power and supports efficient sleep states on legacy platforms without issues.
