Hey guys, I am upgrading my brothers Dell pc. Now, We are getting a new psu and monitor. A GTX 1650 Super and A thermaltake 850 psu gold. Now, I am getting a 8 to 24 pin adapter for the psu to hook it up to a dell custom motherboard. Now I am wondering if this pc will run well. It has an i5 9400 processor and 8gb of ram. Here is a picture of the pc. And I am wondering if the psu and graphics card will fit.
