So im looking for a PC upgrade, but to upgrade my GPU i've decided that i need a PSU upgrade. (current GPU GTX 1050 TI and i want to upgrade to AMD RX 570/580/590 i still cant decide). I have a Asus prime B250M-K MicroATX motherboard and my current PSU is CHIEFTEC ATX 2.3 500W PFC 80+ GPA-500S8 and im looking to buy a CORSAIR VS550 550W CP-9020171-EU , My PC case is a no brand random case i found in my basement from 2002 and im not looking to upgrade it, i just wanted to know if there is a way to know if it will fit
