Replace Power 220W Flex-ATX PSU

This 220W proprietary power supply replaces the HP 633195-001 and Bestec FH-ZD221MGR units. It fits the HP TouchSmart 310-1205la desktop and many other slimline systems requiring a Flex-ATX form factor. The grey housing weighs 1 kg and accepts 115 or 230 V input.

Slimline desktop owners needing a direct replacement

Builders who need higher wattage for discrete graphics cards or additional drive bays should look at something else. Systems requiring standard ATX dimensions or different connector layouts cannot use this unit. The proprietary design limits compatibility to the listed HP and compatible slimline models.

24-pin and 4-pin motherboard connectors plus 2x Sata

The connector set determines whether this PSU matches the target motherboard and storage devices. Verify that the host board uses a 24-pin main power socket and a 4-pin auxiliary socket. The two Sata power leads support compatible drives or peripherals.

Questions about this item

How do I install this Flex-ATX PSU into my HP TouchSmart 310-1205la and what is the common mistake?

Align the proprietary Flex-ATX housing with the chassis rails, secure the mounting screws, then attach the 24 pin motherboard connector, the 4 pin connector and the two Sata connectors. The step often missed is fully seating the 4 pin CPU power plug, which can prevent the system from posting.

What maintenance or replacement will this 220W unit need over time?

The internal fan and electrolytic capacitors are the components that age. Expect to clean dust from the fan intake every 6 to 12 months and plan on replacing the supply if voltages drift or the fan becomes noisy after several years of continuous operation.

What limit appears first when this PSU runs at full load for extended periods?

The 220 watt maximum output is the hard ceiling. Sustained loads near that level will hit the over-current protection on the 12 volt rail first, causing the unit to shut down before thermal limits are reached.
