Product overview
The Seasonic 350-Watts 100-240V 24-Pin ATX12V power Supply is supplied under part number SS-350ET. The input side has to suit the rack: voltage, connector and whether the circuit can carry another unit at all. This is a 100-240V supply. Tell us what the PDU presents and we will confirm the variant.
If the part is wrong for your platform we will say so and suggest the one that is, which is cheaper for both of us than a return.

What you get ordering this from us
Ordered by part number
The order is placed against SS-350ET, not against a description of it, so there is no room for a substitution you did not agree to.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
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 SS-350ET genuine and is the warranty intact?
- Yes — new and sealed, with the Seasonic warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will SS-350ET 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.
