So, I recently bought a new pre-built PC, and a GPU along with it. Unfortunately, when buying the PC it didn't list anything about the PSU, and it turns out that it's the bare minimum of 240w, correspondingly not able to power the GPU. I tried looking for a new PSU, but am very confused as to what to look for (not the best with PC building). The one that I have now has three separate cords, a 4 pin, and two 6 pins (One is one row, and the other is two, little pictures to help: One row ...... Two row ::: ). I'm sorry if these have proper names, but I don't know them. Anyways, if someone could help me find a PSU with all of these cords that runs around 550+ Watts, that would be awesome! If you're confused tell me, and other than that thanks for the help!
