Product overview
The Antec SmartPower 350-Watts ATX power Supply is supplied under part number SL350S. 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.
Quote requests are answered within 48 business hours, with availability confirmed before you raise a purchase order rather than after.

What you get ordering this from us
Ordered by part number
Quoted and supplied against SL350S specifically, so what arrives is what your build sheet asks for.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Draw calculated, not assumed
We work out what the configuration actually pulls before recommending a wattage.
Questions buyers ask about this part
Is SL350S genuine and is the warranty intact?
Yes, new and sealed, with the Antec warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will SL350S 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.
