Is a Sentey 750w good enough for a 660 ti sli?

Jackie Coogan · Mar 3, 2014

I have an ERP750-ss psu... and I just upgraded too a gtx 660 ti two-way sli... I´ve donde the calculations at http://www.extreme.outervision.com/PSUEngine and the psu is supusdly more than enough to withstand both card... but I also heard that when your using a generic psu its best to keep the power level down... So is my psu good enough for the gtx 660 sli?

while the wattage is enough for sli 660ti's i'd not recommend that brand as they aren't known for quality. i'd highly highly recommend spending a bit more and getting a seasonic or corsair, or the v series cooler masters, hell even the fortress series from rosewell! you need something 80+ and i'd recommend 80+ silver or gold for added stability. check out johnyguru.com for awesome and honest reviews on powersupply's.

For a system using two GeForce GTX 660 Ti graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 650 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 38 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!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical 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 Sentey Extreme Rock Power Series 750W (ERP750-SS) power supply unit, with its maximum combined +12 Volt continuous current rating of 55 Amps and with two 6-pin and two (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with two GeForce GTX 660 Ti graphics cards in 2-way SLI mode.

Thanks... could you tell me where you got this information... I´ve been looking for it on the web... and in nvidia´s guide book... but there´s nothing and I need to show to a friend...
