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.
| Video engine | H.264 | HEVC 10-bit decode | VP9 | AV1 decode | HEVC encode |
|---|---|---|---|---|---|
| Intel Quick Sync (Skylake) | Yes | No | No | No | Yes |
| Intel Quick Sync (Kaby Lake–Comet Lake) | Yes | Yes | Yes | No | Yes |
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). 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.

- HP's official maximum is 32 GB across 2 DDR4 SODIMM slots at up to 2400 MT/s.
- How many NVMe SSDs can the EliteDesk 800 G3 Mini hold?
- 1 M.2 NVMe slot for storage plus 1 2.5" SATA bay, so up to 2 internal drives.
- Does the EliteDesk 800 G3 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 G3 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 G3 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 i7-7700T, HD 630); check which CPU a listing has.
- How much power does the EliteDesk 800 G3 Mini use at idle?
- about 12 W at the wall at idle, as measured by ServeTheHome (Quad-core Core i5-7500T, 65 W adapter, 120 V). Your drives, BIOS settings and OS will change this figure.
