Product overview
This is the Dell 305-Watts power Supply for OptiPlex 760/780, order code N305P-04. Power supplies must match the chassis, the wattage the configuration actually draws and, in a redundant pair, each other. This unit is 305W. Send us the server model and current PSU part number and we will confirm the pairing.

What you get ordering this from us
Ordered by part number
N305P-04 is what is quoted and N305P-04 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
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.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Questions buyers ask about this part
- Is N305P-04 genuine and is the warranty intact?
- Yes — new and sealed, with the Dell warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will N305P-04 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.
