Product overview
43W9049 is a Lenovo 2500-Watts power Module. Mixing efficiency grades in a redundant pair is the common mistake: the pair runs, then throws a mismatch alert on every boot. Give us the part number already fitted and we will supply its match.
No price is published here because the market for this part moves week to week; ask and we will give you a current one rather than a stale one.

What you get ordering this from us
Ordered by part number
43W9049 is what is quoted and 43W9049 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Matched to the installed unit
Send the part number already in the chassis and we supply its pair, including the efficiency grade that stops the mismatch alert.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
Questions buyers ask about this part
Is 43W9049 genuine and is the warranty intact?
Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
Will 43W9049 work in my server?
Send the server model and the part number of the supply already fitted. In a redundant pair both units have to match on wattage and efficiency grade, or the chassis alerts on every boot.
Do you accept purchase orders and quote at volume?
Yes. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.

Specifying a system, not just the part?
An accelerated node draws far more than a general-purpose server, so power is sized with the build rather than assumed from the chassis.
