What you get ordering this from us
Ordered by part number
Quoted and supplied against 979K1 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.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
Questions buyers ask about this part
Is 979K1 genuine and is the warranty intact?
Yes. It ships new in Dell 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 979K1 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.
