I am doing my build of ITX system and currently it developed to stage where I have power issues.
Setup:
Case: Loggic Supply MC600
MB: Asrock X370
CPU: Ryzen R3 1200
RAM: 2x8GB Kingston
PSU:
HD-PLEX 400
AC/DC
Mean Well 20V GST280A20-C6P http://www.meanwell.com/webapp/product/search.aspx?prod=GST280A
I got into situation that my Mean Well brick thanks to Asus R9 Nano white is running on the edge. (with MSI RX560 it worked fine).
I got even issues to boot system. It restarted about 1-2 second after booting which was clearly over-current protection of brick and booted after several initial resets. It helped that I managed to get into system and undervolted CPU and memory and It boots now every time (at least 10/10 tries. I will keep testing it). Also maybe R9 Nano power part components burned-in meanwhile (cards was for more than year somewhere in stock) I will confirm this theory with more tests.
Anyway obviously currently I am on power edge and have decision in front of me:
1) Replace just brick and purchase Dell 330W brick and keep hd-plex. I like this idea because it is simplier. I have concerns if even 330W brick can hold power spikes caused by R9 Nano. That Mean Well is big f*cking heavy brick which can hold over 30% overload so I wonder what peaks R9 Nano is really generating. Also there are a lot of fakes on market for multiple prices so I am in danger to purchase fake. I have way how to purchase 100% Dell Original but it is pricey (approx 170Euro)
2) Go 12V way with G-Unique PSU and moddel dell brick. PSU looks perfect but I have small concerns about modded brick because it is common step with above. Question is if even modded 330W brick can hodl R9 nano. On the other hand huge gain would be less space occupied inside by PSU so I won't be limited to sub 170mm lenght card like I am right now.
3) any other way? (I am not giving up my R9 Nano because it is beauty ;-))
I would welcome your experience with power spikes and Dell 330W.
(once in OS I can undervolt R9 Nano about -60mV and card is running fine and finish 3d Marks etc. and whole system consumes about ~240W)
