Product overview
HP lists YM-3591A as a 595-Watts 100-240V redundant power Supply. The input side has to suit the rack: voltage, connector and whether the circuit can carry another unit at all. This is a 100-240V supply. Tell us what the PDU presents and we will confirm the variant.
Quote requests are answered within 48 business hours, with availability confirmed before you raise a purchase order rather than after.

What you get ordering this from us
Ordered by part number
Quoted and supplied against YM-3591A specifically, so what arrives is what your build sheet asks for.
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.
Draw calculated, not assumed
We work out what the configuration actually pulls before recommending a wattage.
Questions buyers ask about this part
Is YM-3591A genuine and is the warranty intact?
Yes. It ships new in HP 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 YM-3591A 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.
