180 W 14-pin SFF power cable

This cable connects a compact 180 watt power supply to Q75 or Q77 motherboards that use a 14-pin ATX connector. It is intended for integrators servicing Lenovo ThinkCentre M73, M78, M82, M83 or M93 small-form-factor systems. The part number 54Y8871 matches the HK280-71FP and PS-3181-02 references used in those chassis.

14-pin motherboard connector

The single specification that determines fit is the 14-pin power header found on Q75 and Q77 boards in the listed ThinkCentre models. Standard 24-pin ATX supplies will not mate with this header, so the cable is mandatory when retaining the original mainboard. No other pin count or keying is supported by this assembly.

Active PFC with 100-264 V input

The supply behind this cable uses active power-factor correction and accepts a universal 100-264 volt range at 50-60 hertz. Rated output is 180 watts distributed across +12 V at 14.5 amps, -12 V at 0.2 amps and +5 V at 2.5 amps. Typical acoustic and thermal behaviour follows the original FSP240-40SB unit installed in the same SFF chassis.

Questions about this item

What does the 180W rating mean for my small-form-factor desktop?

It is the peak power the unit can deliver through the 14-pin connector to the motherboard and onboard components in M73 M78 M82 M83 M93 systems.

What does the 14-pin interface cap in practice?

The connector carries +12V at 14.5A and +5V at 2.5A, limiting total output to the rated 180W for the supported Lenovo SFF platforms.

What clearance and mounting points does the cable need inside the chassis?

It plugs directly into the Q75/77 motherboard 14-pin header and the PSU housing used in H530S HK280-71FP units, requiring no extra brackets.
