To Pual and Old Man,


Power Supply
=========
Thx for the great PSU calculator.

It calculated 282W (without motherboard, wireless mouse & keyboard
receiver).
Futhermore, the amount of video RAM might make a difference while the
calculator does not accommodate for this.
Also, most manufacturers do not provide power requirements (motherboards
etc)

To keep a long story short. I think the power supply is close to the edge.
Probably 420...450W would provide enough headroom.
Considering 3 SATA drives spining up after powerdown may cause a 12V
collapse causing serious data damage and RAID failure.

I'll swap the supply for a bigger one, time will tell wether this was the
root cause.


Incomplete answer. If you mean bigger=more watts.

Swap the supply to one from a reputable power-supply manufacturer
<<with adequate +12V current>>. Total Wattage is not the issue.
Modern PC hardware requires lots of +12V current. Total wattage tells
you nothing about the +12V capability.

Preferably a ATXV2.x with dual +12V outputs, typically they have
12 -18 amps per output.
