Compatible Replacement for HP Pavilion Slimline

This 300 watt TFX power supply is built as a direct replacement for the HP Pavilion Slimline s5660f and s5670t models. It fits the small form factor chassis and provides the standard 20+4 pin motherboard connector along with a 4-pin CPU connector. The unit also includes three Molex, one floppy, and three SATA connectors for drives and peripherals. It supports a wide input voltage range of 100 to 240 volts.

Sustained Output and Cooling Behaviour

The supply delivers a continuous 300 watts of power rather than a short-term peak rating. An 80 millimetre fan with double ball bearings handles cooling duties, designed to maintain airflow during extended workloads without excessive noise. The manufacturer notes this unit can upgrade systems originally equipped with 200, 250, 300, or 350 watt units, and the platform supports an upgrade path to 420 watts if higher capacity is later required.

Pre-Installation Checks for Your Build

Verify that your Slimline chassis accepts the TFX form factor and that the existing mounting points align with this replacement unit. Confirm your motherboard uses a 20+4 pin main power connector and a 4-pin CPU power header, as older proprietary layouts will not match. Ensure the three SATA and three Molex connectors meet your current drive count, and check that the 100 to 240 volt input range suits your local mains supply.

Perguntas sobre este artigo

How loud is the 80 mm double ball-bearing fan when the PSU runs at 300 W all day?

The 80 mm fan uses double ball bearings for quiet, reliable airflow; it keeps the 300 W unit cool without excessive noise during continuous operation.

Which cables must my HP Pavilion Slimline already have for this TFX unit to connect?

Your motherboard needs a 20+4 pin socket, the CPU a 4-pin connector, and drives require three SATA plus three Molex plugs; a floppy lead is also included.

Will this 300 W TFX supply work with the original 200 W or 250 W hardware still inside my s5660f?

Yes, it replaces 200 W, 250 W, 300 W or 350 W units and delivers 300 W steady power to the existing motherboard, CPU and drives.
