250W 1U ATX power supply

This 250W 1U ATX unit fits compact server and workstation chassis that require a TFX-style footprint. It is built for system integrators and IT professionals who need reliable power delivery in a 1U rackmount or small-form-factor enclosure.

80 PLUS Gold efficiency and Zero RPM fan

The 80 PLUS Gold certification ensures high efficiency at typical loads, reducing waste heat and lowering overall power draw. A Zero RPM fan mode stops the fan completely at low and medium loads, delivering near-silent operation while temperatures remain controlled.

Modern Standby and LLC topology benefits

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency for always-on responsiveness. The resonant LLC topology with DC-to-DC conversion supplies clean, consistent power, reduces coil whine, and supports deeper, more energy-efficient sleep states.

Questions sur cet article

How do I install this 1U ATX power supply in a rackmount chassis?

Slide the unit into the 1U bay, align the mounting holes with the chassis rails, secure all four screws, then attach the 24-pin ATX and 4-pin CPU power cables; the step often missed is confirming the IEC power cord is fully seated before powering on

What maintenance will this 250 W supply need over time?

The Zero RPM fan mode reduces wear at low load, but dust will still accumulate on the intake mesh; clean it with compressed air every six to twelve months and listen for bearing noise — if the fan becomes audible under load, plan a fan or full unit replacement

What limit appears first when this supply runs at sustained load?

The 250 W continuous rating is the hard ceiling; the 80 PLUS Gold efficiency keeps heat lower, yet prolonged operation near maximum output will raise internal temperatures until the protection circuits throttle or shut down the unit
