Have you recently changed any hardware?
The PSU is awful quality, so that could always be an issue.
Do you have any XMP or overclock enabled?
Is this a system that has just suddenly started doing this?
What is your motherboard?

It looks kind of dusty, when was the last time it was cleaned and all the dust blown out? I saw where dust was making a power supply short out from dust. Sometimes it can be conductive and short things.
