270W Flex ATX for HP Slimline

This 270 watt Flex ATX power supply is built as a direct replacement for HP Pavilion Slimline models 492674-001, S3020N, S3100N and S3120N. It fits the Mini ITX form factor used in those slim chassis and delivers 11 amps on the 12 volt rail.

Suits owners of listed Slimline PCs

The unit matches the original 270 watt rating and connector layout for the four listed model numbers. Builders working on other small-form-factor systems should verify pin-outs and dimensions before ordering.

11A 12V output decides fit

The single 12 volt rail rated at 11 amps determines whether the supply can handle the installed components. Check the graphics card and CPU power draw against that 11 amp limit to confirm compatibility.

Questions about this item

Will the 40 mm cooling fan need replacement after a few years of continuous use?

The unit uses a single 40 mm fan; like any sleeve or ball-bearing fan it will eventually wear, so plan to swap it if noise or airflow drops noticeably.

What power limit will be reached first when the system runs at full load for hours?

The +12 V rail is rated at 11 A; sustained draw above that level will trigger protection even though the total label rating is 270 W.

How loud and hot does the supply get when it powers a Slimline all day?

The 40 mm fan runs constantly; expect a low hum and modest warmth, but the supply is designed for the Slimline chassis airflow.
