Hewlett-Packard 18E7 Motherboard — Feature Draft

Overview The HP 18E7 is a compact, business-class motherboard designed for small-form-factor desktops and all-in-one systems, offering a balanced mix of performance, onboard connectivity, and manageability for enterprise and prosumer environments.

TDP Limit: The VRM (voltage regulator module) on the 18E7 is designed for 65W CPUs. Using a 95W or 125W chip (e.g., i9-9900K) will cause thermal throttling and potential shutdowns. If you upgrade to an i7-9700 (65W), you are safe.
BIOS Version Required: To run a 9th Gen CPU, your BIOS must be version 2.20 or higher. Update from HP Support Assistant before swapping chips.

Form Factor: Proprietary (designed specifically for HP ProDesk 600 G1 chassis). hewlett-packard 18e7 motherboard specs
