Frequently Asked Questions
Is HP Elite Mini 800 G9 worth the premium price?
Yes, for enterprise environments. vPro management, TPM 2.0, and enterprise support justify the cost. For consumers: consider Geekom/consumer mini PCs (cheaper, same performance).
Can I upgrade to 64GB RAM?
Yes. 2× 32GB DDR5 SO-DIMM (£150–200). i7-13th gen handles 64GB without issue.
Should I add 2.5″ SATA?
Yes, if you need 1TB+ storage for archival or backup. £45–60 for 500GB–1TB SATA.
Can I use HP Elite Mini 800 G9 for personal use?
Yes, but enterprise features (vPro, TPM) are wasted. Geekom/consumer mini PCs offer better value for personal use.
How long will Elite Mini 800 G9 be supported?
Intel 13th-gen through 2027–2028. HP enterprise support extends these timelines further (3–5 years post-release).
