TFX 14-Pin 240 W PSU

This TFX power supply delivers 240 watts through a 14-pin connector for compatible small-form-factor desktops. It carries 80 PLUS Gold certification for high efficiency and supports Modern Standby for rapid wake-from-sleep. The unit is new and built with resonant LLC topology plus DC-to-DC conversion.

Suits owners of listed Lenovo models

The unit matches the FSP240-40SBV 54Y8897 replacement for Lenovo H3050, M4500, M92P, M82, M78, M73, M93, E73, M83, M91 and M4550 systems. Builders using standard 24-pin ATX motherboards or cases requiring higher wattage should choose a different power supply.

Direct swap in supported chassis

Installation is a direct swap in the listed Lenovo chassis using the existing 14-pin connector. The zero-RPM fan mode stays off at low and medium loads for silent running. No standard ATX 24-pin adapter is included, so non-listed boards cannot be powered.

Questions about this item

Which Dell OptiPlex models use the same 14-pin connector as this 240W TFX unit?

The supplier lists compatibility with OptiPlex 3050, 4500, 92P, 82, 78, 73, 93, E73, 83, 91 and 4550 models.

Will the Zero RPM fan mode still engage if I keep an older mechanical hard drive in the system?

Yes, the fan remains off at low and medium loads regardless of drive type, so a mechanical drive will not prevent silent operation.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

Check that the PSU fan stays off during light desktop use and that the system enters Modern Standby sleep with near-instant wake times.
