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) | State | Power draw | Notes | | ----------------------------------- | ---------- | ---------------------- | | Off (standby) | 0.8W | Wake-on-LAN enabled | | Idle (Jellyfin running, no streams) | 7-9W | Typical: 8W | | 1x Direct Play (1080p) | 8-10W | Almost no CPU increase | | 1x Direct Play (4K HEVC) | 9-11W | Minimal CPU for muxing | | 1x HW Transcode (4K to 1080p, QSV) | 12-16W | GPU active | | 2x HW Transcode (4K to 1080p, QSV) | 15-20W | GPU at ~60% | | 3x HW Transcode (4K to 1080p, QSV) | 18-24W | GPU near max | | Library scan (full) | 14-18W | CPU + disk active | | Tdarr encoding (QSV) | 18-25W | Sustained 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) | State | Power draw | Notes | | --------------------------- | ---------- | --------------------------------- | | Idle | 10-13W | 8 cores, slightly higher baseline | | 1x Direct Play | 11-14W | | | 1x HW Transcode (QSV) | 16-22W | | | 3x HW Transcode (QSV) | 22-30W | More 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) | State | Power draw | Notes | | ---------------------- | ---------- | ----------------------- | | Idle (drives spinning) | 15-18W | 2x HDD spinning | | Idle (drives sleeping) | 8-10W | HDD hibernation enabled | | 1x Direct Play | 16-20W | | | 1x HW Transcode (QSV) | 20-25W | J4125 iGPU | | Library scan | 22-28W | Drives 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) | State | Power draw | Notes | | ----------------------------- | ---------- | ----------------------------- | | Idle | 4-5W | Minimal baseline | | 1x Direct Play | 5-7W | | | 1x Software Transcode (1080p) | 12-15W | CPU at 100%, throttling | | 4K Software Transcode | Not viable | Thermal 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) | State | Power draw | Notes | | --------------------- | ---------- | --------------------- | | Idle (lid closed) | 12-18W | Display off, Wi-Fi on | | 1x Direct Play | 14-20W | | | 1x HW Transcode (QSV) | 22-30W | 8th gen QSV | | 2x HW Transcode | 28-38W | | **Annual cost:** 16W average = **$21.02/year** Surprisingly efficient. Old laptops are underrated Jellyfin servers. * * * #### Old Desktop PC (2016 Intel i5-6500, no dGPU) | State | Power draw | Notes | | -------------------------- | ---------- | ---------------------------- | | Idle | 45-65W | PSU inefficiency at low load | | 1x Direct Play | 50-70W | | | 1x HW Transcode (QSV) | 60-80W | 6th gen QSV | | 1x Software Transcode (4K) | 90-120W | CPU 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 | State | Power draw | Notes | | ----------------------- | ---------- | ----------------------- | | Idle | 55-75W | GPU idle power + system | | 1x Direct Play | 58-78W | | | 1x HW Transcode (NVENC) | 70-95W | GPU video engine active | | 5x HW Transcode (NVENC) | 90-130W | GPU at moderate load | | Gaming + Transcoding | 250-350W | Full 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) | State | Power draw | Notes | | ---------------------------- | ---------- | ----------------------- | | Idle | 120-180W | Fans, 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. * * * ### Summary Table **JellyWatch**Try JellyWatch โ€” Your Jellyfin companion, everywhere.

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 | Hardware | Annual kWh | CO2 equivalent (US grid avg) | | ----------- | ---------- | ---------------------------- | | Intel N100 | 105 kWh | 44 kg CO2 | | Old Desktop | 570 kWh | 239 kg CO2 | | Rack Server | 1,314 kWh | 552 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. * * * > **Know what your server is doing (and costing you).
