240 W ATX power supply for SFF builds

This 240 W ATX unit fits small-form-factor desktops such as the 390 and 790 chassis. It delivers the rated output for office workstations and basic home PCs. The supply has been tested and confirmed working before dispatch.

Capacity and headroom for low-power systems

The 240 W rating comfortably handles integrated graphics, a single storage drive and modest CPU loads. It runs out of headroom when a discrete graphics card or multiple drives are added, so builders needing more power should choose a higher-wattage unit.

Questions about this item

Will the 240w output run the legacy PCI cards I keep in my 390 chassis?

The unit delivers 240w total power through standard ATX connectors, matching the original supply specification for the 390 and 790 SFF models.

How do I verify the RV1C4 unit is operating correctly once installed?

The supply is test-working from the factory; after fitting, the system should boot normally and the PSU fan should spin steadily under load.
