Jellyfin Power Consumption Guide 2026: Real Measurements for N100, N305, NAS, and Old PCs (Kill-A-Watt Tested)

Jellyfin Power Consumption Guide 2026: Real Measurements for N100, N305, NAS, and Old PCs (Kill-A-Watt Tested)

Jellyfin Power Consumption Guide 2026: Real Measurements

Your Jellyfin server runs 24/7/365. That is 8,760 hours per year. Even a small difference in power draw adds up to real money over time. An old desktop pulling 80W costs $105/year in electricity. An Intel N100 mini PC pulling 10W costs $13/year. That is $92/year in savings, which pays for the mini PC itself in 18 months.

This guide provides real-world power measurements across common Jellyfin hardware, measured with a Kill-A-Watt meter under actual Jellyfin workloads.


How We Measured

  • Tool: P3 Kill-A-Watt P4400 electricity meter
  • Methodology: Measured at the wall outlet (includes PSU efficiency losses)
  • States tested: Idle (server running, no streams), 1x 1080p transcode, 1x 4K transcode, 2x simultaneous transcodes
  • Software: Jellyfin 10.11.7, Docker, Ubuntu Server 24.04
  • Electricity cost: $0.15/kWh (US average 2026)

Power Measurements by Hardware

Intel N100 Mini PC (Beelink Mini S12 Pro)

StatePower drawNotes
Off (standby)0.8WWake-on-LAN enabled
Idle (Jellyfin running, no streams)7-9WTypical: 8W
1x Direct Play (1080p)8-10WAlmost no CPU increase
1x Direct Play (4K HEVC)9-11WMinimal CPU for muxing
1x HW Transcode (4K to 1080p, QSV)12-16WGPU active
2x HW Transcode (4K to 1080p, QSV)15-20WGPU at ~60%
3x HW Transcode (4K to 1080p, QSV)18-24WGPU near max
Library scan (full)14-18WCPU + disk active
Tdarr encoding (QSV)18-25WSustained GPU load

Annual cost at idle: 8W x 8,760h x $0.15/kWh = $10.51/year Annual cost typical use: ~12W average = $15.77/year


Intel N305 Mini PC (Beelink EQ13)

StatePower drawNotes
Idle10-13W8 cores, slightly higher baseline
1x Direct Play11-14W
1x HW Transcode (QSV)16-22W
3x HW Transcode (QSV)22-30WMore headroom than N100
Full load (Tdarr + streams)28-35W

Annual cost at idle: 12W average = $15.77/year Annual cost typical use: ~18W average = $23.65/year


Synology DS224+ (NAS, Intel J4125)

StatePower drawNotes
Idle (drives spinning)15-18W2x HDD spinning
Idle (drives sleeping)8-10WHDD hibernation enabled
1x Direct Play16-20W
1x HW Transcode (QSV)20-25WJ4125 iGPU
Library scan22-28WDrives active

Annual cost: 17W average = $22.34/year

Note: NAS power includes the hard drives. A diskless mini PC + external USB drive would be comparable.


Raspberry Pi 5 (8GB)

StatePower drawNotes
Idle4-5WMinimal baseline
1x Direct Play5-7W
1x Software Transcode (1080p)12-15WCPU at 100%, throttling
4K Software TranscodeNot viableThermal throttle, unwatchable

Annual cost: 5W average = $6.57/year

Cheapest to run, but no hardware transcoding. Direct Play only.


Old Laptop (2018 Intel i5-8250U)

StatePower drawNotes
Idle (lid closed)12-18WDisplay off, Wi-Fi on
1x Direct Play14-20W
1x HW Transcode (QSV)22-30W8th gen QSV
2x HW Transcode28-38W

Annual cost: 16W average = $21.02/year

Surprisingly efficient. Old laptops are underrated Jellyfin servers.


Old Desktop PC (2016 Intel i5-6500, no dGPU)

StatePower drawNotes
Idle45-65WPSU inefficiency at low load
1x Direct Play50-70W
1x HW Transcode (QSV)60-80W6th gen QSV
1x Software Transcode (4K)90-120WCPU at 100%

Annual cost: 60W average = $78.84/year

This is where the money bleeds. An old desktop costs 5-7x more to run than an N100 mini PC.


Desktop PC with NVIDIA RTX 3060

StatePower drawNotes
Idle55-75WGPU idle power + system
1x Direct Play58-78W
1x HW Transcode (NVENC)70-95WGPU video engine active
5x HW Transcode (NVENC)90-130WGPU at moderate load
Gaming + Transcoding250-350WFull GPU + CPU

Annual cost: 70W average = $91.98/year

Powerful but expensive to run 24/7. Best as a dual-purpose gaming/media PC that sleeps when not in use.


Full Rack Server (Dell PowerEdge R730, Dual Xeon)

StatePower drawNotes
Idle120-180WFans, dual PSU, ECC RAM
Active (multiple transcodes)200-350W

Annual cost: 150W average = $197.10/year

Overkill for Jellyfin. Only justified if running 20+ other services alongside.

The Upgrade Break-Even Calculation

Should you buy an N100 mini PC to replace your old desktop?

FactorOld DesktopIntel N100 Mini PC
Purchase cost$0 (already own)$130
Annual electricity$85$16
Annual savings-$69/year
Break-even-22 months

After 22 months, the N100 has paid for itself in electricity savings. After 3 years, you have saved $77 net. After 5 years, $215 net.

If your old desktop draws 80W+ at idle, the upgrade pays for itself in under 2 years.


Tips to Reduce Power Consumption

1. Use hardware transcoding

Software transcoding uses 4-8x more power than hardware transcoding for the same task. Always enable Intel QSV or NVIDIA NVENC.

2. Optimize for Direct Play

Direct Play uses near-zero additional power. Encode your library in H.265 with AAC/EAC3 audio so clients Direct Play without transcoding.

3. Enable HDD sleep on NAS

If your media drives are not being accessed, let them spin down. Saves 5-8W per drive.

4. Schedule heavy tasks overnight

Tdarr encoding, library scans, and Intro Skipper analysis spike power draw. Schedule them during off-peak electricity hours if your utility offers time-of-use pricing.

5. Use Wake-on-LAN (advanced)

If your server is only used a few hours per day, configure Wake-on-LAN. The server sleeps at 1W and wakes when a client connects. Saves 50-80% of annual electricity for light-use servers.


Environmental Impact

HardwareAnnual kWhCO2 equivalent (US grid avg)
Intel N100105 kWh44 kg CO2
Old Desktop570 kWh239 kg CO2
Rack Server1,314 kWh552 kg CO2

Switching from an old desktop to an N100 saves ~195 kg of CO2 per year. That is equivalent to driving 480 fewer miles.


FAQ

Does Jellyfin itself use much power? No. Jellyfin at idle uses <1% CPU. The power draw is dominated by the hardware platform (PSU efficiency, fans, drives), not the software.

Does the number of library items affect power? Minimally. A 10,000-item library uses the same idle power as a 100-item library. Power only increases during active scans or transcoding.

Is an N100 powerful enough despite using so little power? Yes. The N100 handles 3-4 simultaneous 4K transcodes via QSV while drawing only 20W. Power efficiency and performance are not mutually exclusive with modern hardware.

Should I turn off my server at night? For most users, no. The convenience of 24/7 availability outweighs the $1-2/month in overnight electricity. If you only use it 2-3 hours/day, Wake-on-LAN is a good compromise.
