I've got a charger that requires a power supply, it's a hassle to hook it up to the car battery, so I decided to convert an old PC power supply. I made a trip to Radio Shack for some parts, and I have an old PC gathering dust under my workbench. I'm in...

I went to two online PSU calculator, and the results are very different. On extreme power supply claculator , the result is 290 W.

These power supply calculators are only as good as the data which populates for most applications.

It looks like I've got a dead Antec True 330 power supply in an older desktop that has an Intel D845PESV motherboard, a Pentium 2.4GHz processor, 2 dvd/cd writers, 2 hard drives, and other typical devices.
I have an even older computer that is not being...

But i'd.
That has a better power rating and that wastes less electricity if you can get that 350W and it has happily with a 250W supply, including two hard disks, two DVD drives and an old Radeon 9600XT.

Is a larger-capacity power supply likely to live longer than a lower-capacity supply, even if they both have plenty of capacity for the system they're on?
For example, say I have a system where the typical load is 200 W and the max load is 350 W during...

I have just bought a new power supply for my PC.
Can I plug it in and start it up without inserting into my PC?
I want to see how loud it is.
Will it blow up?

Does the computer turn on when you remove the fan from the power supply? There may be a short in it, but it's nigh impossible.
It isn't unusual for fans to be connected directly to the power supply.
