TFX 240W Power Supply for compact builds

This TFX form-factor unit delivers 240 W of continuous power for small-form-factor desktops and slimline workstations. It fits systems that require the narrower TFX footprint rather than standard ATX dimensions. The 80 PLUS Gold certification confirms high efficiency across typical loads. Builders upgrading or repairing space-constrained chassis will find the output suitable for mainstream components.

80 PLUS Gold efficiency with Zero RPM fan mode

Gold-rated efficiency reduces waste heat and keeps power draw low during everyday workloads. The Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion supplies clean, consistent voltage and minimises coil whine. Modern Standby compatibility enables extremely fast wake-from-sleep transitions and better low-load efficiency.

Replaces older TFX units lacking Gold efficiency

This supply upgrades TFX systems still running lower-efficiency or constantly spinning units. The jump is worthwhile when quieter operation and reduced heat output matter in a compact case. It is not suited for builds that demand higher wattage than 240 W or require standard ATX dimensions. Buyers needing more power headroom for discrete graphics should look elsewhere.

Questions about this item

How do I fit this TFX 240W unit into my slimline case and connect the 24-pin and CPU cables?

Slide the TFX chassis into the bay, secure it with four screws, then attach the 24-pin motherboard connector and the 4+4-pin CPU cable; the step people miss is routing the cables before the final screw so the side panel closes cleanly.

Will the 80 PLUS Gold fan need cleaning or thermal-paste replacement after a few years?

The Zero RPM fan mode keeps the fan off at low and medium loads, so dust builds slowly; a yearly blast of compressed air through the grille is usually all the maintenance required.

At what load does the 240W limit trigger protection during long rendering sessions?

Continuous draw above 240W activates over-power protection and shuts the unit down; stay below that ceiling for sustained work.
