I bought a Geforce 650 GTX. I see it needs a 6 core power plug. However my power supply is a 470 Watt Gigabyte and only has one four core plug that slots into my motherboard. Does this mean I need as new Power Supply? :-(
Ahh.. The good ol' days when Gigabyte made PSU's...
Nope I remember nothing!
Yes, get a new PSU, at least 500w+ for future proofing. And not just any 500w PSU, you should get one that is well branded. My pick is Antec, Corsair, XfX,etc ( I forgot the other brands but someone will tell you, however, these are a personal favourite)
