No overclocking. I want to do some gaming eventually, I have 1 cheap gpu but plan on getting two midrange, 7870's. First off is this good voltage for not wanting to oc, second is it suffice to add on to over time. I just need to know if I will be scathing by or if I am in the clear.
intel i5 3470 stock cooler
Toshiba 1tb hdd
8gb of no name ram
rosewill capstone 750m
Nvidia gt 620 2gb (LOL)
No Name dvd drive
Thanks ahead of time for any answers and yes i'm a noob, kinda well....whatever!
For a system using two Radeon HD 7870 GHz Edition graphics cards in 2-way CrossFireX mode AMD specifies a minimum of an 600 Watt or greater power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 40 Amps or greater and have at least four 6-pin PCI Express supplementary power connectors.
Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.
Overclocking of the CPU and/or GPU(s) will 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 you are trying to achieve.
The Rosewill Capstone Modular Series 750W (CAPSTONE-750-M), 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 Radeon HD 7870 GHz Edition graphics cards in 2-way CrossFireX mode.
