HP EliteDesk 800 G3 Mini
Specification and Upgrade Options
The HP EliteDesk 800 G3 Mini is a micro-form-factor business desktop designed to disappear onto the back of a monitor or sit unobtrusively on a desk. First available in 2017, this unit relies on the Q270 chipset to run 7th gen Intel Core processors and up to 32GB of SODIMM DDR4-2400 memory. It is the ideal choice for strictly business environments or home media centers where physical space is the primary concern, rather than raw graphical expansion.
This device is easy to upgrade with additional RAM and storage. Usually models with this chassis have an optional Wi-Fi and Bluetooth module and an M.2 slot for an SSD drive.
Can you upgrade HP EliteDesk 800 G3 Mini to play games?
HP EliteDesk 800 G3 Mini is a business desktop computer in micro form factor. It is using a processor that provides both the CPU and GPU functionality. While integrated GPUs are sufficient for basic gaming, they are not powerful enough to run demanding games. HP EliteDesk 800 G3 Mini has no space for dedicated graphics card.
Micro desktop machines like HP EliteDesk 800 G3 Mini are usually used as home theater PCs (HTPC), in home lab projects or a as home automation servers.
Does HP EliteDesk 800 G3 Mini support Windows 11?
No, HP EliteDesk 800 G3 Mini does not meet the Windows 11 hardware requirements. According to Windows 11 specification, all models with Intel 7th Gen CPU or older are not officially supported. Processor with TPM 2.0 and a UEFI Secure boot BIOS is also required in order to upgrade from Windows 10 to Windows 11 through Windows Update.
However, anyone with PC that does not pass the upgrade test can download the official Windows 11 ISO, make a bootable flash drive, and install the OS manually.
Processor
The HP EliteDesk 800 G3 Mini supports Gen7 Intel Core technology on a Q270 chipset. 7th generation Intel Core CPUs (Kaby Lake) refine Skylake with higher clocks and better media support. Performance depends on the specific SKU, with high-end models well-suited for programming, virtualization, and homelab use. Emulation performance is strong for most platforms, while CPU-heavy gaming and advanced emulation may still be constrained by core counts.
Best CPUs for HP EliteDesk 800 G3 Mini upgrade:
| Model | Cores (Threads) | Base frequency | Turbo |
|---|---|---|---|
| Core i5 7500 | 4(4) | 3.4 GHz | 3.8 GHz |
| Core i5 7600 | 4(4) | 3.5 GHz | 4.1 GHz |
| Core i7 7700 | 4(8) | 3.6 GHz | 4.2 GHz |
GPU upgrade
It is not possible to upgrade HP EliteDesk 800 G3 Mini with a dedicated GPU due to the lack of space and absence of a PCIe slot. However, you can still use the integrated graphics processor for gaming. There are number of games you can enjoy with an Intel HD and UHD iGPU.
Memory
HP EliteDesk 800 G3 Mini supports up to 32 GB of SODIMM DDR4-2400 RAM across two DIMM slots, with memory speeds up to 2400 MT/s and dual-channel support depending on the installed configuration.
Actual supported memory capacity and memory channels may vary depending on the installed CPU and chipset.
Typical HP EliteDesk 800 G3 Mini memory configurations include 8 GB for everyday productivity and 16 GB for gaming, heavier multitasking, or professional workloads.
Wi-Fi Support
HP EliteDesk 800 G3 Mini doesn't come with any on-board Wi-Fi support. In that case, you have two options to upgrade this model with Wi-Fi. You either use an external USB Wi-Fi adapter (wireless network dongle) or a PCIe-based wireless adapter.
The USB dongle is much more convenient and easy to install, but has less space for a decent antenna and can have thermal problems. On the other hand, the PCIe based adapter is much more powerful, more reliable, and has better antenna, but it is harder to install.
Wi-Fi and Bluetooth wireless adapter upgrades for HP EliteDesk 800 G3 Mini:
| Model | Speed | Frequency | Interface |
|---|---|---|---|
| WiFi 6E (Gig+) Kit | 3000 Mbit/s | 2.4GHz / 5GHz | NGFF M.2 A/E Key |
| Rekong AX210 | 3000 Mbit/s | 2.4GHz / 5GHz | NGFF M.2 A/E Key |
| Gigabyte GC-Wbax200 | 2400 Mbit/s | 2.4GHz / 5GHz | PCIe |
| TP-Link Archer TX50E | 2400 Mbit/s | 2.4GHz / 5GHz | PCIe |
| TP-Link Archer T9UH | 1300 Mbit/s | 2.4GHz / 5GHz | USB 3.0 |
Ports
HP EliteDesk 800 G3 Mini provides a fixed set of external I/O ports for connecting peripherals and displays. Port availability and versions determine supported data transfer speeds and display capabilities.
USB ports
HP EliteDesk 800 G3 Mini includes seven USB ports in total in the following configuration - USB-C 3.0; (6x)USB-A 3.0; with no USB 3.1 ports available.
Video ports
HP EliteDesk 800 G3 Mini features two DisplayPort 1.2 outputs, suitable for modern digital displays.
No HDMI output is available on the motherboard.
Motherboard video outputs require a CPU with integrated graphics. Systems equipped with a dedicated GPU must use the video ports on the graphics card instead.
SSD storage - M.2 sockets and SATA ports
The HP EliteDesk 800 G3 Mini comes with one SATA port(s) for connecting storage devices.
HP EliteDesk 800 G3 Mini has also one M.2 socket(s) that supports PCIe NVMe (PCIe 3.0 x4) or SATA M.2 drives with speed of up to 4 GB/s. This configuration works very well for both gaming and work related tasks.
The M.2 PCIe SSD connector in combination with an NVMe drive allows for higher transfer rates, compared to the old SATA interface. In some situations, NVMe device connected to the M.2 PCIe socket can be more than 5 times faster.
*Keep in mind that some M.2 connectors may not support SATA SSDs. Check the motherboard manual to confirm compatibility.
Best PCIe NVMe drives for HP EliteDesk 800 G3 Mini storage upgrade:
| Model | Form factor / Interface | NAND type | DRAM |
