You have to factor in all the other devices connected to that same power supply.

Unless he has a billion hard drives and/or a billion fans the other components won't make much of an impact.

Without overclocking, the psu could handle your system with no trouble. It could handle it heavily oc'ed too to be honest. Download CPUID HWMonitor and tell me what the voltage outputs are. There is a 3.3, 5, and 12v output reading at the top. They should be as close to the numbers as possible. A little over and a little under is fine but anything like 2.9, 4.6, 11.6 etc would be an issue.

So the voltages appear to be fine, see this screenshot:

Also look at this. Whats with the readings? Clocks are at 0's?

Not sure if this is helpful:

No clue what those zeroes mean. I guess gpu-z is unreliable for that sort of thing? But yeah your psu is just fine.

Well, CPUID doesn't even show the radeon.
