Hey guys need help heres my specs hp 550 153 i3 4170 intel hd 4400 8gb ram 1tb hard drive 180w psu i want to put a EVGA gtx 750ti and a EVGA 450 BT, 80+ Bronze 450W psu in i was wondering if all these new upgrades will fit in my case and if not what would be the best options for another gpu ( that had the same used price point around 100$ and performance ) and another psu at the same price point i found this one on amazon for 41$

Take a ruler meassure your pc case, and read the GPU and PSU size from their manufacturer website.

That's what anyone would do.
