Hi guys, this is my current set-up:
i7-3770s
Samsung 830 128GB
H77m-itx
8GB samsung green ram
Slim slot loading blu-ray drive
HD-Plex H3.SODD
120w PicoPSU/ 300W SFX PSU
I'm having problems with my computer shutting down under heavy load (converting videos, prime95 etc) but i'm not really sure why.
At first I thought it was a heat issue but running real temp with CPU usage at 99-100% shows temps of around 80c which is fine.
Next I thought it was the 120w Pico psu not giving enough juice so I connected a 300w atx psu, the computer ran fine all the way through the prime95 tests without shutting down.
Great I thought, but before I took the plunge on a more powerful pico psu I decided to buy a power meter to see exactly what size supply I would need, (here is the strange part) with the cpu at 99-100%, a blu-ray being ripped and copying a big file to the ssd from an external drive, the system only pulled ~80W.
The only things I can think of are:
-The pico psu has a 20 pin mobo connector whilst the atx psu has a full 24 (I didn't think this would matter, i thought the extra 4 were for the pci-e bus)
-The pico psu didn't come with the seperate 4 pin connector (auxillary?) So i used a molex to auxillary connector such as this one : No hotlinking! I understand this auxillary is to provide extra power for the CPU, but if that is the problem, why is it a couple of minutes of 100% cpu usage before it shuts down?
-I've been shafted and the 120w pico psu isn't 120w. I can't see any markings on it to identify it as 120w but I bought it from a respectable vendor.
