Product overview
The Supermicro 2000W 80 plus titanium redundant hot-swap power Supply for Supermicro 1U servers is supplied under part number PWS-2K04A-1R. Power supplies must match the chassis, the wattage the configuration actually draws and, in a redundant pair, each other. This unit is 2000W. Send us the server model and current PSU part number and we will confirm the pairing.
Ask for the datasheet and firmware notes with the quote; we would rather you check our claim than take it.

What you get ordering this from us
Ordered by part number
PWS-2K04A-1R is what is quoted and PWS-2K04A-1R is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
Draw calculated, not assumed
We work out what the configuration actually pulls before recommending a wattage.
Questions buyers ask about this part
- Is PWS-2K04A-1R genuine and is the warranty intact?
- Yes. It ships new in Supermicro packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
- Will PWS-2K04A-1R 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 — POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.

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.
