This is an Nvidia Quadro P400 graphics card GPU with full height PCIe bracket. It has 2GB of RAM, and uses a PCIe 3.0 x16 connector.
This GPU is a nice option for PLEX video transcoding as it supports the following NVENC codecs:
H.264 (AVCHD) YUV 4:2:0H.264 (AVCHD) YUV 4:4:4
H.264 (AVCHD) Lossless
H.265 (HEVC) 4K YUV 4:2:0
H.265 (HEVC) 4K YUV 4:4:4
H.265 (HEVC) 4K Lossless
However, it is limited to a max of 3 concurrent NVENC sessions.
This GPU card is also very small, making it ideal for PLEX servers that cannot accommodate longer GPU cards.
