The issue is with the pico PSU, but I'll get to that just after some quick background..
This is an HTPC build, primarily to play 4k content and specifically aiming for 4k/60Hz capability.
Parts are:
APU/mobo as above
8Gb 2666Mhz today, 3200Mhz arrives tomorrow.
Samsung 960 Evo M.2
DC-DC nanoPSU 150W, 150W AC-DC adapter both sourced from AliExpress.
Problem is, the board failed to boot with my picoPSU. The case came with a 65W dohickey, yes you read correctly, 65W, so I tried that for kicks and it actually works. I don't want to leave it there too long though so gotta find a solution for that. I already ordered a couple of replacements from Ebay but they won't arrive for a couple of weeks at best.
Board arrived with the P4.40 BIOS, showed no M.2 installed and the CPU temp bug (showed 127°C). Updated to 4.51a for now. After that was able to install Windows & currently have it running at 3840x2160/60Hz so initial aim achieved. However I really don't want to put any kind of load (e.g. decode h.265) on it until I fix this PSU issue. Hasn't complained using the 65Wer but I assume it's only a matter of time.
I had to do a small mod with this PSU, as the RAM sticks sit right next to the ATX power and as the PSU has connector cables for 12V ATX, Sata etc the cables jut out over the ram sticks. I would actually prefer not to use them (the connectors) at all, as I don't have any devices (no ODD, only M.2 storage) but the 12V ATX is attached to the same strand and the DC lead is the other one. So I ended up slicing off the connector clips, the little overhanging teeth that grab onto the connecter base. It's still a tight fit anyway so no risk of anything, now --just-- sneaks in under the Corsair LPX. Had to cancel the G.Skill V as there's not a snowball's chance in hell of it fitting under these connectors.
Anyway, the symptom with 150W PSU is: hit power button, CPU fan spins up for a couple of seconds and stops again. So something is failiing initial checks. I replace the 150w Pico with the 65W horizontal DC-DC board that came with the case (I had taken it out the day it arrived) and everything boots up and is so far running quite happily.
So my question is, any ideas/experience on BIOs settings that may be conflicting with the power output from these picoPSUs? I actually bought two of them (from the same seller) and both show the exact same behaviour.
As everything is better with pictures, here's the case, and my avatar is the internal build, kind-of.
Any insights would be appreciated..
As an aside,, I'm not a fan of these makeshift PSUs. A FlexPSU that barely takes the space of a 3.5" drive only costs around $30 as a starter and seems like it would save a ton a hassle for everyone. Where space is an absolute premium, ok, I get it, but how often is that really the case?
