damaged BQT S6-SYS-UA 550W
First of all sorry if I type in english.
My PSU is this
My system has random freezes but I found a "condition" to make the system freeze almost for sure (useful to test if freeze problem is solved):
-overnight memtest or overnight resting in bios setting page
The problem is related with the supply for the video card but the strange thing is that the system seems not suffer stress test at all! Freezes are completely random.
I found that using a "molex to PCI-E" converter I can drain power from a different rail (instead of using the rail that provides the two PCI-E power connectors) and I have no more freezes!
So the issue is 100% power supply related.
What do you think? Is there the possibility my power connections are not well balanced? (I means if there is something that drain power from the PCI-E rail).
My system is minimal:
