FSP P3 20-pin 145 W unit

This 145 W power supply uses a 20-pin ATX connector and is built for compact systems that require Modern Standby support. It suits builders who want fast wake-from-sleep behaviour and high efficiency in a small form factor.

Build integration and space

The ATX form factor fits standard chassis layouts while the 20-pin connector matches legacy or proprietary motherboards that lack the 24-pin interface. Zero RPM fan mode stops the fan at low and medium loads, reducing acoustic output and freeing thermal headroom for other components. Resonant LLC topology with DC-to-DC conversion delivers stable rails and supports deeper sleep states.

Capacity limits and headroom

Rated at 145 W, the unit comfortably powers entry-level processors, integrated graphics and a modest complement of drives. It runs out of headroom when a discrete graphics card or multiple high-current peripherals are added, so builders planning heavier loads should look elsewhere.

Questions about this item

What is the maximum continuous power this 145W unit can deliver before its protection circuits engage?

The power supply is rated for 145W continuous output. Protection circuits will activate if the load exceeds this limit to prevent damage to the unit and connected components.

How loud is the fan and what temperatures should I expect when the PSU runs at full load all day?

The Zero RPM Fan Mode keeps the fan off at low and medium loads. Under sustained high load, the fan spins to maintain safe temperatures, aided by the 80 PLUS Gold efficiency which reduces waste heat and noise.

My motherboard has a standard 24-pin ATX connector. Will this 20-pin PSU work without an adapter?

No, this unit provides a 20-pin main connector. A 20-pin to 24-pin adapter is required to connect it to a standard 24-pin ATX motherboard socket.
