Hi there guys, i want to build gaming pc with followin components:
- Intel Core i5-4670
- MSI Z87-G45 GAMING
- Corsair 8 GB (2x4GB) DDR3 2000 MHz
- GIGABYTE GeForce GTX670 GV-N670OC-2GD
- WD Caviar Black WD1002FAEX
The question is, which power supply module do i need to use (around 120$), if i'm going to SLI this gtx670, and wich PC case will you recommend for this needs (with no lights, or with those, which i can turn off, around 100$)
For a system using two NVIDIA reference design GeForce GTX 670 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 700 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 45 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors.
Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most important factor.
Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.
The XFX ProSeries 750W Modular Edition (Bronze)(P1-750X-XXB9), with its maximum combined +12 Volt continuous current rating of 62 Amps and with four (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with two GeForce GTX 670 graphics cards in 2-way SLI mode.
