Checked against: HP Maintenance and Service Guide. Official limits can be lower than what owners report working.

What owners should know

  • HP's official maximum is 32 GB; owners commonly report 64 GB working.
  • Its predecessor, the 800 G4 Mini, officially has two M.2 SSD connectors; HP's G5 QuickSpecs is no longer online, so the G5 count is unconfirmed.

Power consumption

Not measured yet. We only publish idle figures with a source, the configuration and the method. If you have measured one at the wall, send us your reading (CPU, RAM, drives, OS, meter and date). See how to measure idle power.

What to buy with it

  • 32 GB RAM kit

    2 SODIMM slots, 32 GB official maximum. DDR4 laptop-size modules (not desktop DIMMs, not DDR5).
  • 2 × NVMe SSD
    M.2 2280 NVMe SSD (PCIe), e.g. 1 TB with DRAM cache or HMB for VM storage
    2 M.2 2280 storage slots. Two drives allow a ZFS mirror or separate boot and VM storage.
  • 2.5" SATA SSD + caddy · optional
    2.5" SATA SSD (7 mm), plus the model's drive caddy/cable if the unit did not ship with one
    1 × 2.5" bay.
  • Second network port · optional
    HP Flex IO module
    Vendor module: match the exact module version to this generation before buying.
  • Power adapter (if missing) · optional
    HP 65 W or 90 W adapter with the correct connector
    Many ex-office units are sold without one. Use the wattage the manufacturer lists for the CPU fitted.

We list the spec to look for rather than a price, because part prices change daily and we only show prices from a live source.

Plex and Jellyfin transcoding

Handles 10-bit HEVC (typical 4K HDR) in hardware. No AV1 decode, so AV1 files fall back to the CPU. The table covers every CPU option sold in this chassis. Check which CPU a listing actually has.

Intel Quick Sync (Kaby Lake–Comet Lake)YesYesYesNoYes

Plex needs a Plex Pass for hardware transcoding; Jellyfin does not. More detail in our Quick Sync generations guide.

Before you buy one used

  • Confirm the exact CPU model in the listing photos or System Information screenshot, not just "Core i5".
  • Check that a power adapter of the right wattage is included (65 W or 90 W). Many ex-office units ship without one.
  • Ask whether the BIOS is unlocked. Ex-corporate machines sometimes keep an admin password.
  • A 2.5" drive needs the caddy and cable, which are often missing when a unit shipped with only an M.2 SSD.

Frequently asked questions

How much RAM does the EliteDesk 800 G5 Mini support?
HP's official maximum is 32 GB across 2 DDR4 SODIMM slots at up to 2666 MT/s. HP's official maximum is 32 GB; owners commonly report 64 GB working.
How many NVMe SSDs can the EliteDesk 800 G5 Mini hold?
2 M.2 NVMe slots for storage plus 1 2.5" SATA bay, so up to 3 internal drives.
Does the EliteDesk 800 G5 Mini have a PCIe slot?
No. It has no internal PCIe slot; the only internal expansion is HP Flex IO module.
Can the EliteDesk 800 G5 Mini use 10GbE or 2.5GbE networking?
Not internally. It has a 1 GbE Intel I219-LM; faster networking needs a USB adapter.
Is the EliteDesk 800 G5 Mini good for Plex or Jellyfin?
Handles 10-bit HEVC (typical 4K HDR) in hardware. No AV1 decode, so AV1 files fall back to the CPU. That applies to the best CPU option (Core i7-9700T, UHD 630); check which CPU a listing has.
How much power does the EliteDesk 800 G5 Mini use at idle?
We have not published a sourced measurement for this model yet, and we do not estimate one. Idle draw depends on CPU, drives, BIOS power settings and OS.
