Product overview
Part number PWR-M120-AC-S identifies this Juniper 2000-Watts 100-240V AC power Supply unit. Headroom matters more than the label wattage once GPUs or a full drive bay are in the chassis. This supply is rated 2000W. Tell us the configuration and we will work the draw out rather than guess at it.
Ask for the datasheet and firmware notes with the quote; we would rather you check our claim than take it.

Questions buyers ask about this part
Is PWR-M120-AC-S genuine and is the warranty intact?
Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
Will PWR-M120-AC-S 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.
