250W ATX Power Supply

This 250W ATX unit suits small-form-factor PCs and upgrades for systems such as the b520, b520r2, b520e or 1088 platforms. It replaces older 8-pin designs including FSP250-20AI, PS-3251-01, DPS-250AB-71B and DPS-250AB-71A. Builders needing higher wattage or a 24-pin main connector should look elsewhere.

Thermals, Noise and Power Draw

80 PLUS Gold certification delivers high efficiency, reducing waste heat and keeping temperatures lower during normal use. Zero RPM Fan Mode stops the fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion further cuts coil whine and supports efficient sleep states.

Bundled Features

Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. The DC-to-DC design provides clean, consistent power across rails. No modular cables, RGB lighting or software suite are included with this unit.

Preguntas sobre este artículo

How do I install this ATX 250W power supply and what step is often missed?

Mount the unit in the case with four screws, connect the 24-pin ATX and 8-pin EPS cables, then enable Modern Standby in the UEFI so the fast wake-from-sleep feature actually works.

What maintenance will this 80 PLUS Gold supply need later?

Clean dust from the intake grill once a year; the Zero RPM fan only spins under load so bearings last longer, and the Gold-rated internals have no user-replaceable parts.

What limit appears first when this 250W unit runs at sustained load?

The 250 watt continuous ceiling is reached before thermal throttling, so total system draw must stay below that figure to avoid shutdown.
