AMD GPUs won’t do hardware transcoding period. So any low end GPU will work. You may want to research how many transcodes that CPU can do. Because you needed 6. I’d imagine you will be OK but I haven’t looked at the Benchmark data compared to what Plex needs for each transcode.
AMD GPU's including Radeon & Vega / Integrated Vega graphics work on Windows, via the dxva2 API.
So technically the OP could get a Radeon card, or more useful, could use a G series Ryzen like the 3400G to enable hardware acceleration.

Passmark says this cpu is a little above 1700. Okay ill do some research on gpu. Any suggestions on a power supply?
If you get a Plex Pass, or Emby Premiere and do hardware transcoding, then the passmark score of your CPU is largely irrelevant.
Stick with a CPU with integrated graphics and use hardware to do the transcoding. Intel i3 9100 or Ryzen 3200G can easily do what you want, without a discrete GPU and considerably less power.
What PSU you get depends on if you go integrated graphics or discrete GPU, and what case you go for.
Really you need to decide how many drives you want, and what sort of form factor. From there you can work out what cooler & PSU you need.
In my living rooms i have an i3-7100 with a Z270 in a RVZ02, and an i3-8100 with a B360 in a Node 202.
They both have Noctua L9x65 coolers, NVMe boot drive, Silverstone SFX PSUs and space for 2 x 3.5" hard disks (one of them has a GTX1070 instead).
Theyre both easily capable of a dozen transcoded streams if they were Plex servers, using QuickSync (ones a Steam Gaming machine, the other is a Kodi Media Center)
Just pointing out you don't need such an expensive CPU and discrete graphics, and by eliminating these you can easily create a compact efficient solution if you use some high capacity disks.
My Plex server does run on one of my servers with a Ryzen 3950x, but it only has 2 CPU cores & 4GB memory assigned, the GTX1070 does all the lifting and can easily do over 20 x 1080p transcoded streams. Most of the CPU & Memory assigned to my Plex VM is for the other ~12 applications I have running on there as well.
