What you get ordering this from us
Ordered by part number
J12 is what is quoted and J12 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
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 processor class
Above a given TDP the standard heatsink throttles; we check the CPU part number, not just the chassis.
Questions buyers ask about this part
- Is J12 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 J12 work in my server?
- Send us the server model or service tag and we will confirm before you order. Part numbers alone do not always settle it — firmware revision and platform generation matter, and this is the check that prevents a return.
- 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.
