From what I know, at the moment HDPLEX have:
DC-ATX:
- 160 W (I heard the latest version can handle peak up to 200 W)
- 400 W
AC-DC Nano PSU:
- 80 W
- 160 W
- 300 W
Price is about there I guess. For lower price, you might want to find pre-owned ones in forum / reddit etc. Other alternatives are Minibox Pico PSUs or
@guryhwa's G-Unique PSUs.
Do note that, again, IIRC, HDPLEX are 19V solution, while others are 12V.
