I'm pretty sure my power supply is fried. Noticed a funny burning smell, like dust in the toaster, this morning. Later on my computer suddenly died, with the smell much stronger and seeming to come from the PSU. I'm looking to swap out the power units as cheaply as possible, it doesn't need to last. One, I need to get everything off my hard drive onto external, and two, I'm getting a mac mini soon (can't afford it just now though).
I've found this one:

And here's a pic of mine:

Pretty sure I'm on the right track, but wanted to double check before I fork out $30.
Am I likely to run into any trouble?
Cheers, Nic.
