PCB033 280W PSU for Lenovo systems

This power supply delivers 280W through a fixed 14-pin motherboard connector and a 4-pin CPU plug. It carries 80 PLUS Bronze efficiency with active PFC across a 100-264V input range. The unit fits compatible Lenovo desktops and servers such as the M82, M92, H530 and M8400 families. Non-modular cables keep installation straightforward.

Suits owners replacing a failed PCB033

Builders needing modular cables or higher wattage for discrete graphics should look elsewhere. Systems requiring a 24-pin ATX motherboard connector or additional PCIe power leads cannot use this supply. The fixed 14-pin layout limits use to the listed proprietary platforms.

Single 14-pin motherboard connector decides fit

The proprietary 14-pin main connector plus 4-pin CPU plug must match the host board exactly. Only the models listed in the compatibility data will accept this pinout. Verify the motherboard connector before purchase.

Questions about this item

Which compatible model number should I select for my Lenovo M82 or M92 server?

Match the original PSU label to the listed alternatives — HK280-23FP, HK28025FP, HK280-22PP, PCB037, PCB038 or PS-3181-03PE-3181-01 — and choose the one that matches exactly.

What does the 280 W rating deliver to a server motherboard and CPU in practice?

The unit supplies up to 280 W total through a 14-pin motherboard connector and a 4-pin CPU connector, with active PFC and 80 PLUS Bronze efficiency at 100-264 V input.

How does the 14-pin plus 4-pin interface limit upgrade options?

The fixed 14-pin motherboard and 4-pin CPU connectors are non-modular and provide no PCIe power pins, so discrete graphics cards requiring auxiliary power cannot be supported.
