A replacement board arrives without the service tag, licence bindings and BIOS settings of the one it replaces, and iDRAC or iLO entitlements have to be re-applied.

What you get ordering this from us
Ordered by part number
B650EM-A is what is quoted and B650EM-A is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
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.
Questions buyers ask about this part
Is B650EM-A genuine and is the warranty intact?
Yes, new and sealed, with the ASUS warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will B650EM-A work in my server?
Send the service tag and tell us which CPUs and DIMMs you are moving across. Boards are matched by generation, socket and firmware revision, and an adjacent generation will not take the same processors.
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.
