Product overview
M821J is a Dell 525-Watts power Supply for Precision T3500/T5500. 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.
We return an itemised quote within 48 business hours, and we say plainly when a part is constrained rather than quoting a date we cannot hold.

What you get ordering this from us
Ordered by part number
Quoted and supplied against M821J 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.
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 M821J 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 M821J 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.
