Ok so my psu has 1 x 20 + 4 pin connector 1 x 8 pin connector 1 x 4 pin connector 2 x peripheral Quick release connectors 4 x SATA (two Molex) 1 x Floppy 1 x PCI-E. The gpu I want to connect (gtx760) requires 1 x 6 pin PCI-E and 1 x 8 pin. Now the 4 pin on my psu comes out of (connected to) the 8 pin and I need the 4 pin for my CPU now I could buy an extender but this begs the question since there both on the same wires will this overload the rail rated at 16 amps since my CPU gpu combo would be technically on the same connector? Also I know I could use the molex if the above doesn't work out but doesn't that run on a 5v so the 15amps there wouldn't be enough would it?
What to look for in a power supply
One of the most frequently asked questions when building a computer or changing /upgrading components is "how much do I need for a PSU". Without knowing what your components will draw as a whole and what you currently have for a power supply you can... See full content
Because I get a lot of guff for my choice in psu and from an electrical stance point the psu will work more then well. Its an rosewill rd450-2-SB, 2 12v rails one is a 16amp the other 14, 450 watt. My setup for reference is: i5 4430 (84 watts/7 amps) h81m p33 (not sure amps or what's here but I hear its usually between 10-50watts) 8gb 1600 MHz crucial ram (also unsure of actual watt/amp consumption) evga sc 760 (170 watts/14.16666666666667 amps) 1tb sata II hard drive and one 120gb pny xlr8 ssd.
