  • 24 V 10.5 A output provides 250 W of reliable power

24 V 250 W ATX Power Supply

This unit delivers a steady 24 V output at 10.5 A for a total of 250 W. It fits the standard ATX form factor and is built for systems that require a single high-current 24 V rail rather than the multi-rail layouts found in typical desktop supplies.

Replaces older group-regulated 24 V units

The move to resonant LLC topology with DC-to-DC conversion removes the cross-load regulation issues of legacy designs. The efficiency gain from 80 PLUS Gold certification pays off when the system runs long hours at light or medium load, and Modern Standby support is essential for builds that rely on instant wake from sleep.

Standard ATX mounting simplifies the swap

Four screws secure the chassis and the 24-pin main connector plugs directly into the motherboard. Builders sometimes forget to enable Modern Standby in the BIOS after installation, which leaves the fast-wake capability inactive. Another common oversight is leaving the zero-RPM fan curve at its default setting when the case airflow is restricted, causing the fan to spin up earlier than expected.

Questions about this item

Will the ATX form factor fit my standard case?

This unit follows the ATX form factor so it mounts in any case designed for ATX power supplies using the standard four screw holes on the rear panel.

Which cables do I connect first during installation?

Seat the 24 pin motherboard connector and the 4+4 pin CPU power cable before routing any peripheral leads; forgetting the CPU power plug is the most common reason a build will not post.

How long does the Zero RPM fan mode stay off before the fan spins up?

The fan remains stopped at low and medium loads and only starts when internal temperatures rise past the controller threshold, so typical desktop work stays silent.
