The Surprisingly Powerful HP Elite Mini 800 G9: A Tiny Titan for Home Labs and Enterprise Workstations
If you're in the market for a compact, energy-efficient desktop PC that doesn’t skimp on performance, the HP Elite Mini 800 G9 might be exactly what you're looking for. Despite its small 1-liter form factor, this tiny desktop packs a surprising punch, delivering enterprise-grade features, great performance, and a wide range of customization options.
First Impressions: More Than Meets the Eye
At first glance, the HP Elite Mini 800 G9 might seem like just another small form factor (SFF) office PC. But once you dive into the hardware, the picture changes. It features Intel’s 12th-generation Alder Lake processors, support for DDR5 memory, and room for expansion — all in a chassis that barely takes up any space on your desk.
Key Features
-
Intel Alder Lake CPUs: The unit we tested came with an Intel Core i5-12500T — a 6-core, 12-thread processor with a 35W TDP. While this version skips efficiency cores, it still offers strong single-threaded and multi-threaded performance, perfect for general productivity or running lightweight virtual machines.
-
DDR5 Memory: Supporting up to 64GB of DDR5 SODIMM memory, the Elite Mini 800 G9 provides future-ready RAM speeds and bandwidth.
-
Ample Storage Options: With dual M.2 PCIe Gen4 SSD slots and an optional 2.5" SATA bay (adapter required), there's plenty of room for storage upgrades.
-
Exceptional Connectivity: Includes USB-C (20Gbps), multiple USB-A (10Gbps), HDMI 2.1, dual DisplayPort 1.4a, and optional rear expansion with HP’s Flex IO V2 module.
Flex IO V2: Customization Powerhouse
HP’s Flex IO V2 port allows you to tailor your system’s rear I/O to your needs — choose from Thunderbolt 3, extra USB-C/A ports, DisplayPort, VGA, or even 2.5GbE/10GbE networking. This is a standout feature that gives the Elite Mini 800 G9 incredible versatility.
Performance and Efficiency
The i5-12500T model is impressively efficient, with idle power consumption as low as 4–7 watts and maximum draw around 65 watts under load. Despite the compact form factor, the cooling system is effective and quiet — even at full load, the system remains nearly silent.
That said, users looking for extra horsepower might consider stepping up to the i7-12700T, which offers 12 cores (8P + 4E) and a significant 25–33% performance boost.
Network Upgrades and BIOS Considerations
While the unit comes standard with 1GbE networking via Intel’s i219-LM chip, it can be upgraded to 2.5GbE or even 10GbE with the right expansion card. A caveat: enabling 10GbE requires disabling Secure Boot, which may be blocked if the BIOS is password-protected. HP’s current generation models lack easy reset options for BIOS passwords, so caution is advised when buying used units.
Optional GPU Support
Some configurations of the Elite Mini 800 G9 support a dedicated NVIDIA RTX 3050 Ti GPU. While our test unit didn’t include one, this option makes it a viable choice for light content creation or gaming in a super-compact form factor.
Who Should Consider It?
-
IT professionals or developers building a home lab or testing environment
-
Enterprises needing compact, reliable, and powerful desktop workstations
-
Media center enthusiasts looking for a silent and capable PC
-
Tinkerers who want modular I/O and upgrade paths in a small footprint
Final Thoughts
The HP Elite Mini 800 G9 exceeded expectations in nearly every way. With its small size, excellent performance, low power usage, and rich customization options, it’s one of the most flexible ultra-compact PCs on the market. Whether you’re managing virtual machines, serving media, or just need a dependable desktop with room to grow — this tiny titan delivers.
