Product overview
This is the Seasonic 400-Watts 100-240V ATX power Supply, order code SS-400ES. Power supplies must match the chassis, the wattage the configuration actually draws and, in a redundant pair, each other. This unit is 400W. 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
The order is placed against SS-400ES, not against a description of it, so there is no room for a substitution you did not agree to.
Draw calculated, not assumed
We work out what the configuration actually pulls before recommending a wattage.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
Questions buyers ask about this part
Is SS-400ES 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-400ES 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. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.

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.
