I7 3770 + GT 730 Not enough to transcode?

From reading before i built this it should be overkill to stream 3 sessions, but transcoding to lan from 4K to 1080 1 session pegs cpu to 100% 30% on GPU using HW for both decoding and encoding. Is the audio killing the PC?

No it’s not enough. No it’s not the audio.

Neither your cpu, gpu, support 4K/hevc decoding or encoding.

Also, gpu transcoding requires plex pass, which your forum account doesn’t seem to indicate.

I do have plex pass, and GPU on chart supported 5X transcodes

As @TeknoJunky states, your system is not powerful enough to transcode 4K HEVC video.

The i7-3770K is not powerful enough to transcode 4K in software (Ref 1, Ref 2).

The Intel HD Graphics 4000 in the i7-3770K does not support decoding HEVC video (ref).

The GT 730 does not support decoding HEVC video (Ref).

HDR to SDR tonemapping is compute intensive, and Plex does not support tonemapping on Nvidia GPUs with Windows 10 (Ref).

If you want to transcode 4K HEVC HDR video in Plex you will need to replace your Plex Media Server. You’ll need a 7th gen or later Intel CPU (for HEVC 10-bit decoding) preferably running Linux (for tonemapping support).

Thanks, apparently did not read deep enough when i built this.
