Product overview
Part number SS-300FS identifies this Seasonic 300-Watts power Supply. Headroom matters more than the label wattage once GPUs or a full drive bay are in the chassis. This supply is rated 300W. Tell us the configuration and we will work the draw out rather than guess at it.
Send the quantity you need and we will come back within 48 business hours with availability confirmed, not estimated.

What you get ordering this from us
Ordered by part number
The order is placed against SS-300FS, 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.
No substitutions without asking
If we cannot supply the exact code we tell you what we can supply and why, rather than shipping an equivalent and letting you find out.
Questions buyers ask about this part
Is SS-300FS genuine and is the warranty intact?
Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
Will SS-300FS 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.
