As I am a newbie at this, I've come to realize my power supply and graphics card both suck and I got ripped off quite a bit. I'm a more hardcore gamer and am looking to upgrade my graphics card, but it seems that my power supply is pretty bad as well so I might upgrade that as well.
What power supply is recommended for my computer? Are they all the same size and shape and fitting? And can I do this all on my own or should I seek professional help to do this?
PC - Acer Predator G5910
cpu - Intel Core i7-2600 3.4GHz
graphics card - Nvidia GT 545
RAM - 16GB of idk what
Power supply - 216W apparently?
