It is possible that one of the capacitors got fried. The PSU would be my first suspect. Look into RMAing the PSU after you perform the simple "paper clip" test. The paper clip test will confirm whether the PSU is dead or not (not a test for under load).

jemm's link will show you the paper clip test. This test will tell you whether the PSU is dead or alive; it is not a load test.

It could be due to a manufacturing defect resulting from a bad capacitor. Bad capacitors do slip through final inspection and testing sometimes. (The price of perfect quality is infinite!)

Yes. Get the one I have - Corsair HX850 - been in service for 2 years; works flawlessly. It is available in the UK, but I don't have a link for that.
