I have one fan at the moment but honestly do not know how to tell how much power my power supply puts out or how to change that or install a new fan. If I need to alter either of these, I can find a tutorial online, but would like to keep things simple.
If the 570 won't work, please feel free to suggest another card or what I could do to my rig to make it work.
Thank you, I appreciate your time and input.
UPDATE: I have a prebuilt (I was stupid to get prebuilt, I know. I will build in the future...). It is a HP Pavilion Elite HPE 500y. The psu is 300w. I did some further reading online and saw that the 570 requires ~500w. Any suggestions on a new psu? I seriously haven't the slightest clue on what is good/compatible. Can I just dig around Newegg or are there certain things I should know?
