PC power supply blowing fuse

[mitchy11111]

Hello there,

This is the first time I have posted.
My PC power supply keeps blowing the fuse. it tends only to be when I am doing something that uses alot of memory, especially when trying to convert .avi files into .mpgs
The PS is 450w and I have an athlon 2400 processor and 192MB RAM
Do you think the power supply is inadequate as I have upgraded it recently and it doesn't blow the fuse as often now but it still does it when using alot of memory. I have tried it in different sockets and have the same probs.

Any help would be greatly appreciated. Mitchy

What make of psu is it?

If it's a cheap, generic brand, or PowMax, that's why it blows the fuse.

Replace the power supply... it should shut down before it's fuse blows

Not sure what make it is. It wasn't very expensive. any recommendations for a good one

If you can afford this one, it would be great:

FSP Group ATX 450W PSU

But to really recommend a good PSU for you, we need to know your system specs
