Which fuse to use?

Just had my computer die while I was playing Medal of Honour. Swapped the 5 Amp fuse in the plug for a 3 Amp one and everything worked fine - for about 5 minutes, then that one blew as well. Not sure what's in there at the moment (probably 5 Amp) as I've now swapped the power cord for one from a spare monitor (couldn't be bother prising the old one out again). Anyway, the only other fuses I have handy are 13 Amp ones - would I be tempting fate if I stuck one of these in the plug?

It's for a 550w PSU which is powering: a 3.0GHz P4, FX5950 Ultra graphics card, 2 optical drives, 2 SATA drives, 5 fans, 1 FDD, a Creative Labs drive bay interface and (of course) the motherboard.

Hmmm. I wouldn't recomend using anything other than a 5amp. If you use something to high then instead of the fuse blowing something more expensive might.

The question is why did the original 5amp fuse blow. Could be a faulty PSU.... Has anything on your system changed recently?

Ah, thought so. Nothing's changed recently (well, the machine's only 4.5 months old - self built), but the PSU isn't the best in the world - QTec.

This did happen once before when I was playing Black & White, but I didn't think anything of it. Might have to look at getting a better supply.

There could be a short which could be lethal if something's shorting through the case, so far better to have a fuse blow than kill yourself. If it's happened several times, then I'd bin the PSU. Don't try servicing it yourself as they store lethal currents even when disconnected.
