Product overview
L305P-00 is a Dell 305W desktop power Supply (24-pin ATX+PFC, for dimension 3100/5100/5150/E310/E510/E520/E521, OptiPlex GX320/GX620, PowerEdge SC430/SC440). Headroom matters more than the label wattage once GPUs or a full drive bay are in the chassis. This supply is rated 305W. Tell us the configuration and we will work the draw out rather than guess at it.
Send the part number of the supply already fitted and we will match it rather than merely match the wattage.

What you get ordering this from us
Ordered by part number
Quoted and supplied against L305P-00 specifically, so what arrives is what your build sheet asks for.
Draw calculated, not assumed
We work out what the configuration actually pulls before recommending a wattage.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
Questions buyers ask about this part
- Is L305P-00 genuine and is the warranty intact?
- Yes. It ships new in Dell 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 L305P-00 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.
