Enermax Liberty 500w Power Supply

The supplied kettle type lead has got a 13A fuse fitted. My previous PSU's had 5A fuses fitted as have most of my power leads. Do I need a 13A fuse on this PSU? Anyone else got the same PSU with a 13A fuse?
Was going to contact Enermax but I seem to be getting through to India so thought I would try this forum???

hmmmmm...didn't think to email. I'll give that a go.

I emailed Enermax Support and to thir credit they replied in 15 mins. They say 13amp is correct (not the best English though and I still suspect via India?).

I've looked at the spec for the PSU but it doesn't quote power consumption. They are supposed to be 80% efficient so does that mean consumption would be 500 + 20% = 625 Watts.

Is the consensus that it should be a 5 amp fuse?

I emailed Enermax again with a more specific question and this was their reply:
"Ac cord is for universal. If input voltage is 230V, maximum input
current is 4 amp, so 5 amp fuse is enough.
However, if I/V is 110V, the max. I/C is over 9.5 amp, then we should
use 13 amp fuse is enough. Our power supply is for universal, so we must
choose 13 amp."
So uk users should?could? use a 5 amp fuse. I will change mine tonight.
