180W ATX Power Supply for Small-Form-Factor Systems

This 180W ATX unit targets compact desktops and replacement builds that require a 4-pin connector. It fits chassis designed around 600 and 800 series platforms where space and power draw are limited. The 80 PLUS Gold rating keeps heat and electricity costs low.

Modern Standby and Zero RPM Fan Mode

Modern Standby compatibility enables rapid wake-from-sleep and improved low-load efficiency for everyday responsiveness. Zero RPM mode stops the fan completely at light and medium loads, delivering near-silent operation in quiet environments. Resonant LLC topology with DC-to-DC conversion reduces coil whine and provides stable voltage rails.

Replaces Proprietary 4-Pin Units in Legacy Chassis

This supply replaces OEM models such as D16-180P3A, D16-180P2A, D19-180P1A, PA-1181-6HK and PCK017 without adapter cables. The upgrade is worthwhile when the original unit fails or when louder fan noise and lower efficiency become noticeable. It is not for builders who need higher wattage or standard 24-pin ATX connectivity.

Questions about this item

Does the 4-pin ATX connector on this 180 W unit limit the power the motherboard can draw?

The 4-pin ATX connector supplies the CPU power rail; it is rated for the full 180 W output of this supply.

What clearance is required for the 180 W ATX chassis?

Standard ATX dimensions apply; ensure the case has room for a typical ATX power supply and its rear exhaust.

How is the 4-pin ATX connector seated, and what mistake should be avoided?

Align the keyed 4-pin plug with the motherboard socket and press until the latch clicks; do not force a 4-pin into an 8-pin CPU socket.
