Dell 580 PSU Upgrade

I recently purchased a new Dell Inspirion 580 and want to upgrade the video card, which will require an upgrade to the Power Supply since it comes with 300 watt PSU.

I spoke to a Dell rep who said I shouldn't because it will fry the board. This made me seriously consider the expertise of Dell reps, since I have posted similar questions on the PSU upgrade in other forums and was told this was a bunch of hogwash.

With that being said, has anyone upgraded their 580 power supply? If so, any issues? What make/model PSU?

Thanks

Will this do?

Sorry no. I have not done this to a Dell Inspiron 580. But over the years have upgraded hundreds if not more machines with other power supplies.

What I'm wondering is this. Does it matter that you may not find someone with this specific machine? It's something like a battery for your car. If it's the right physical size, voltages and connections you can use a bigger one.

Bob, thank you. I appreciate your insight as one experienced in such things. That was what I was thinking, but wanted to get a second opinion.

Power Supply

It certainly will not fry your machine unless you make a mistake installing it. However, you will probably void your warranty.
