Hey im really new to this so please bare with me. My friend installed a nvidea gtx 960 into my i7 3668 inspiron and informed me I would need to upgrade my 240w power supply in order to get it to work. I'm sorry I don't have the measurements but I could update this post after work today. I'm blind when it comes to building a gaming pc and he referred me to this forum. I'm sorry if I didn't give enough info, I'll gladly try to when I get off work. Thank you so much!

okay then, here is the service manual for your computer https://www.manualslib.com/manual/1247209/Dell-Inspiron-3668.html
Once you open your case you will see the power supply (pointed out below with arrows) it is NOT a standard ATX size (sold in all stores) how to remove it begins at page 72 of the manual.
now all that said, your biggest problem will be to find a power supply to fit in that space and of at least 400-500w
looks like a TFX, (would have to get measurements to make sure...) PSU.

now a lead to help you find one would be this ebay auction, they have a PSu very similar to what you need, and they may be able to better help you in your search worth asking the questions in any case...
if your desktop at the back looks like this you may have an issue as this doesn't look like an standard ATX PSu but a BTX one.

it looks like this particular power supply may fit and provide you the power you need, I would ask them first before buying it.
