looking to Upgrade tower

[zallik]

I'm new to this so i was wondering if i could get some help.

i am currently running
Mbo-Asus p8b75m
Cpu-core i5 3570k
Psu-aywun 500w
Gpu-galaxy gt620
Hdd-Western Digital Caviar Black 1TB
Ram-8GB Corsair Vengeance DDR3-1600MHz
optical drive-LG GH22 SATA DVD+/-RW Dual-Layer DVD Burner
all in a N81 Mid Tower

so i was looking to upgrade the gpu to a Asus gtx670 and was wondering
if i also needed to upgrade the case and psu?
any help will be appreciated thanks.

If your psu is of decent quality and has 2 6 pin pci-e connectors, it should run a GTX670.
I see no reason why a GTX670 will not properly fit in your case.

unfortunately it only has 1x 6-pin PCI-Express
any recommendations?

You can get a molex to 6 pinn adapter If you have an extra molex plug that is not being used.
