350 Watt Flex ATX supply

This Replace Power RPSUFLEX350W is a 350 Watt Flex ATX power supply designed as a direct replacement for specific HP Pavilion Slimline desktops. It suits owners of listed models such as the s3200n, s3500f and 5188-7520 who need a reliable unit to restore operation or support added internal devices.

Sustained output for extra hardware

The unit delivers its rated 350 Watt continuously rather than only in short peaks, allowing stable power when additional drives or expansion cards are installed. Its high-quality construction helps maintain consistent voltage under prolonged load without unexpected shutdowns.

Flex ATX form factor limits

The Flex ATX physical standard restricts this supply to chassis built for that exact layout, so it will not fit standard ATX or micro-ATX cases. Buyers must verify their system uses the Flex ATX mounting pattern and connector set before purchasing.

Questions about this item

How much heat and noise does the 350W Flex ATX unit produce during continuous operation?

The supply delivers 350 watts in a Mini ITX form factor weighing 1.65 kg; typical Flex ATX designs use a small internal fan that runs whenever the system is on.

Which cables or connectors must already be present in the HP Slimline chassis for this replacement to work?

It replaces the original Delta DPS-160QB and AC BEL PC6012 or PC6034 units, so the existing motherboard power header and drive connectors in the listed Pavilion models are used directly.

Will the RPSUFLEX350W fit and power an older HP Pavilion s3200n that currently runs a 160W supply?

Yes, the unit is listed as a direct replacement for the s3200n and other Slimline models such as s3000, s3100n, s3400f, s3500f, s3521, s3707c, s7310n, s7320n and s7700n.
