Product overview
Part number NE550M identifies this Antec NeoECO 550-Watts 100-240V 8-4A ATX12V power Supply. Mixing efficiency grades in a redundant pair is the common mistake: the pair runs, then throws a mismatch alert on every boot. Give us the part number already fitted and we will supply its match.
No price is published here because the market for this part moves week to week; ask and we will give you a current one rather than a stale one.

What you get ordering this from us
Ordered by part number
The order is placed against NE550M, not against a description of it, so there is no room for a substitution you did not agree to.
Matched to the installed unit
Send the part number already in the chassis and we supply its pair, including the efficiency grade that stops the mismatch alert.
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 NE550M genuine and is the warranty intact?
Yes, new and sealed, with the Antec warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will NE550M 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.
