Compact TFX Replacement

This TFX form-factor power supply targets owners of slimline desktops such as the H3050 who need a higher-wattage unit. It delivers a continuous 350 W with a 500 W peak rating to support graphics upgrades or additional drives. The 14-pin main connector matches the proprietary motherboard header found in these chassis. Builders working in standard ATX cases cannot use this unit.

Modern Standby and Zero RPM

Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. The 80 PLUS Gold certification reduces power draw, heat and fan noise across the load range. Zero RPM mode stops the fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion supplies clean power and minimises coil whine.

Direct Swap Installation

Installation is a direct swap: remove the original unit, connect the 14-pin motherboard cable and the standard peripheral leads, then secure the supply with the existing screws. No adapter cables or case modifications are required. The proprietary 14-pin connector prevents use with standard 24-pin ATX motherboards. Cable lengths are tailored to the original slimline layout, so routing in larger cases may be awkward.

Questions about this item

Does the 14-pin connector on this TFX unit require any periodic replacement?

The 14-pin connector is a fixed part of the power supply and is not designed to be replaced separately during normal use.

What limit is reached first when this 350W supply runs at full load continuously?

The 350W continuous power rating is the primary limit; exceeding it triggers the unit's protection circuits.

How much noise and heat does the Zero RPM fan mode produce during all-day operation?

At low and medium loads the fan stays off for silent running; under heavier sustained loads the fan spins to manage temperatures.
