Product overview
JPSU-350-AC-AFO is a Juniper 350-Watts 100-240V power Supply for EX4300. Headroom matters more than the label wattage once GPUs or a full drive bay are in the chassis. This supply is rated 350W. 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 JPSU-350-AC-AFO specifically, so what arrives is what your build sheet asks for.
No substitutions without asking
If we cannot supply the exact code we tell you what we can supply and why, rather than shipping an equivalent and letting you find out.
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.
Questions buyers ask about this part
Is JPSU-350-AC-AFO genuine and is the warranty intact?
Yes. It ships new in Juniper 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 JPSU-350-AC-AFO 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. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.

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.
