Product overview
Fujitsu lists A3C40105779 as an 800-Watts power Supply for primergy RX300. The input side has to suit the rack: voltage, connector and whether the circuit can carry another unit at all. Tell us what the PDU presents and we will confirm the variant.
Quotes are itemised down to the accessories, so nothing that is needed to make the part work is left off and discovered later.

What you get ordering this from us
Ordered by part number
A3C40105779 is what is quoted and A3C40105779 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
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 A3C40105779 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 A3C40105779 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.
