So a friend at work bought a 980 and is willing to lend me his old 770 to play around with but slight concern about PSU Current specs Intel i5 4590 MSI H97M E35 4GB DDR3 1600 AMD 7850 2GB 1x SSD 1x 7200 RPM HDD 1x DVDRW 5x Case fans Corsair K65 Logitech G500 PSU: ocz modxstream pro 500w 2x 12V rails with 18amps on each Psu comes with the correct connectors 1x 6pin 1x 8pin But should I really risk using a GTX 770 ? It's the ASUS 770 OC as far as i know.
