I bought a Dell Optiplex 7040 mini-tower recently. It has an i7-6700 octa-core processor, 8gb ram. I wanted to upgrade it's hardware so I can play high demanding games on it. I slotted in a GTX 1050ti low profile and a 450w pcu but it doesn't fit inside so I left it sitting outside the case for now. My problem is whenever I run games like Tomb Raider or Fallout 4, the computer shuts off after a few minutes. I thought it was an overheating problem so I removed the case cover then pointed a ventilation fan while I running a game again but still, the computer shuts off. Can anyone help me? Thanks

you can start by downloading and running speccy, post the log here, this will show the temps of your system

 

AFTER you run speccy i would inspect the cpu fan and heat sink assembly,

 

do they look dusty and dirty?

 

even if you cant see much dust i would remove them and clean them, apply new thermal paste when reinstalling

 

run speccy again after you clean the fan/heat sink and post here again

 

in my experience, aftermarket power supplies dont normally fit into dell cases, they have a unique power supply design

What brand 450W psu are you using? A Seasonic SS-350TGM psu should work for that Dell 7040 pc. The GTX 1060ti has a 300W requirement

A cheap 450W psu may or may not be able to provide the necessary power requirements to run your pc. Power supplies are "get what you pay for" and many "cheap" PSU's are not up to spec to what they claim to deliver

Does your case support a standard ATX PSU if so I would say go for something like this - http://amzn.to/2yqSzbs

Google also says you'll need adapter for ATX connector https://www.amazon.com/Eyeboot-8-Pin-Supply-Adapter-Motherboards/dp/B01A210HKO
