Seriously, I need to find out. Usually, I have sufficient motherboards and power supplies to try swapping out one for the other (did the problem move or cease to exist?). Unfortunately, I am down to my last odd motherboard and last odd power supply. The good news, of course, is that the better half is happy that my "techie junk" has diminished substantially! But, I digress.
Mobo: Biostar NM70I-1037U Mini-ITX with Dual-core Celeron 1037U processor
Worked successfully 1 year ago with another power supply and then it and the RAM was put safely away (sealed in plastic).
Power Supply: Mini-Box picoPSU-160-XT High Power 24 Pin for Mini-ITX (small-ish)
Worked successfully 6 months ago with a different mobo and then it was put safely away (sealed in plastic).
Today, I completed a build with the mobo, power supply, a Thermaltake Cube V1 enclosure (includes a case fan), RAM (previously sealed sway), CPU fan (supposedly not needed according to Biostar but I am paranoid), and an SSD. I attempted to power up with 2 different AC/DC power adapters:
- 12V, 5A
- 19V, 2.1A.
1. Observed symptoms with a 12V 5A AC/DC adapter
Push power button.
Loop forever Both fans and power indicator light on for 1 second Both fans and power indicator light off for 2-3 seconds End of loop
2. Observed symptoms with a 19V 2.1A AC/DC adapter
Push power button.
Power light comes on and stays on forever.
Fans do not activate.
Is it the mobo or the power supply?
Opinions, please.
Also, suggestions for further testing, aside from sticking the suspect power supply in another build which I don't have at the moment?
Thank you in advance.
