Product overview
The Antec smart power 400-Watts 115-230V 10A ATX power Supply is supplied under part number SL400. 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
SL400 is what is quoted and SL400 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
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 SL400 genuine and is the warranty intact?
Yes. It ships new in Antec 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 SL400 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.
