Questions about this item

Does the PWS-1K81P-1R include the mains lead and the ATX cables for my build?

The power supply is supplied as a tested working unit; mains lead and any ATX cables required for your system are not included and must be sourced separately.

The model code contains 11 and 81 — do those numbers identify different capacity options I should choose between?

The digits 11 and 81 form part of the single model identifier PWS-1K81P-1R; this unit is offered only in the 1800W rating listed, so there are no alternative capacities to select.

What does the 1800W headline figure mean once the PSU is installed in a server?

The 1800W rating indicates the maximum continuous power the supply can deliver to the system components when operating within its specified limits.
