GTX 780 TI OC - antec 650w PSU, enough? Tags: Gtx Antec Systems Last response: February 17, 2014 5:43 AM in Systems Share chilledzop February 17, 2014 5:38:38 AM Hey guys, Will this: Antec High Current Gamer 620W Power Supply HCG-620 be enough to power a system running a Gigabyte GTX 780 Ti OC. No SLIs, No CPU over clocking. (the cpu is i5-4440 3.1ghz) Will this also give me enough free room to add a couple of HDDs (ssd not an option atm), and add a few more fans to the casing? Also i heard the current of the GTX 780 Ti is 42amps? will this PSU provide that? I have already made a mistake buying an under powered PSU, so advise would be very appreicated right now!
