I recently ordered a 2GB EVGA GeForce GTX 960 (http://www.amazon.com/gp/product/B00SC6HAS4/ref=br_prlt_slcty_pdt-1?ie=UTF8&smid=ATVPDKIKX0DER&pf_rd_m=ATVPDKIKX0DER&pf_rd_s=merchandised-search-3&pf_rd_r=1JG1TJEKVAT1Y5WH1Z9Z&pf_rd_t=101&pf_rd_p=2102772462&pf_rd_i=10779868011) and I forgot to look into a new Power Supply. I currently have a HP Pavilion 500-164 (http://support.hp.com/us-en/document/c03933829) and am wondering will I have enough power to run the new GPU?
