Replacing a power supply--what do I need to know?

I've got a slightly older Gateway desktop that had power supply issues out of the box. Every half hour or so, you'd hear the fans start going crazy for a few seconds, then the computer would shut off. Eventually, the power supply gave out. We bought a new computer, and the Gateway has been sitting around for a while, but it's time to get it back in working order.

I've never had any experience with power supplies, but I've read a few forum posts. Some people seem to have suggested that getting a higher wattage power supply can stop that "overheating" type of thing from happening (there was a debate on whether or not the computer/PSU was actually overheating). But I was initially told that the wattage of the new PSU needs to match the current one. So, which is true? Does the wattage need to stay the same, or can I increase it (and would increasing it help the issue)?

Aside from that, are there any other specs or features that need to match up for a PSU, and any recommended brands/specific units? Current wattage is 400, if that matters. Thanks for any help/opinions!

Some gateway/dell/compaq older computers used proprietary connectors. Just ensure that you check all connectors on your old one with a new replacement powersupply. You want to also ensure you have enough power for the computer so specs of the machine would greatly help us help you find a good powersupply to replace it with. :)

Proprietary connectors? 8D

Sorry, I'm not super computer literate.

Here are the specs for the computer: http://support.gateway.com/s/PC/R/1014737R/1014737Rsp3.shtml

Thanks!

Do you have any opinions about a higher wattage solving the issue of the random shut offs? I'd hate to spend money on another 400w PSU only to find the same thing happening again, and having to replace it in a year. I'm hoping the original was just a bad PSU to begin with and that it doesn't happen, but if going to a 500w might help, I'd be willing to give that a shot (assuming it's compatible..?)

I'm looking at getting this PSU: http://www.tomshardware.com/reviews/power-supply-review-80-plus-bronze,3568-2.html
Is that more high-end/expensive than I should bother going? I've seen them in a cheaper range, but that one seems like a good buy.

Antec, corsair, evga make good powersupplies. There are plenty of others as well people would recommend. I figure depending on where you buy it you may find a decent sale on a powersupply.

Stick with 450 watt minimum. Yes more watts is fine, but at some point having way more is a tad over kill.

That is a good power supply to get.

Sorry to be a bother and keep asking questions. But the one I linked is only 400 watt.

...should I get that one, or get a higher wattage? :| I actually found a 450 w antec for cheaper, but it's sort of like a 'beginner' PSU.
