Product overview
Part number MPX-5501-AMAAB-US identifies this Cooler Master MasterWatt 550-Watts ATX PSU. Headroom matters more than the label wattage once GPUs or a full drive bay are in the chassis. This supply is rated 550W. Tell us the configuration and we will work the draw out rather than guess at it.

Questions buyers ask about this part
- Is MPX-5501-AMAAB-US genuine and is the warranty intact?
- Yes. It ships new in Cooler Master 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 MPX-5501-AMAAB-US 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.
