What you get ordering this from us
Ordered by part number
The order is placed against 21P4970, not against a description of it, so there is no room for a substitution you did not agree to.
Draw calculated, not assumed
We work out what the configuration actually pulls before recommending a wattage.
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 21P4970 genuine and is the warranty intact?
Yes, new and sealed, with the IBM warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will 21P4970 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.
