Power supply upgrade

[fallenapples]

Currently I have a stock psu of 250 watts. I want to upgrade it in order to power my new gpu which requires a minimum of 350 watts. I have an ATX motherboard. The stock psu's fan size is about 3.5 inches. If I upgrade to a bigger psu with a bigger fan will it still fit in my case? And also how can I estimate the total amount of wattage I will need?

Well first things first is we need to know what computer you have if it's a prebuilt or what case you have if it's self built. Then we need to know what GPU you bought.

It could, but I can't see the inside or the back to confirm what size your PSU is.
