Right we installed the cards so let's have a look at how much power draw we measure with these graphics cards active and running.
The methodology: We have a device constantly monitoring the power draw from the PC. We simply stress the GPU, not the processor. The before and after wattage will tell us roughly how much power a graphics card is consuming under load.
Our default test system is based on a power hungry Core i7 3960X/ X79 system. This setup is overclocked to 4.6 GHz (core 1.40V). Next to that we have energy saving functions disabled for this motherboard and processor (to ensure consistent benchmark results). On average we are using a bit more than a standard PC due to higher CPU clock settings, water-cooling, additional cold cathode lights etc.
We'll be calculating the GPU power consumption here, not the total PC power consumption.
|GPU STRESS TEST||IDLE SYS WATT||PEAK SYS
|EST. GPU TDP|
|GeForce GTX Titan||136||372||236||15||251|
|GeForce GTX Titan 2-way SLI||142||598||456||30||486|
|GeForce GTX Titan 3-way SLI||149||843||694||45||739|
Mind you that the system wattage is measured at the wall socket side and there are other variables like PSU power efficiency. So this is a calculated value, albeit a very good one.
Above, a chart of relative power consumption. Again the Wattage shown is the card with the GPU(s) stressed 100%, showing only the peak GPU power draw, not the power consumption of the entire PC and not the average gaming power consumption.
Here is Guru3D's power supply recommendation:
- GeForce GTX Titan - On your average system the card requires you to have a 550 Watt power supply unit.
- GeForce GTX Titan 2x SLI - On your average system the cards require you to have a 800 Watt power supply unit as minimum.
- GeForce GTX Titan 3x SLI - On your average system the cards require you to have a 1000~1200 Watt power supply unit as minimum.
Though we do have some reserves calculated into our recommendation remember this; if you are going to overclock the GPUs or processor, then we do advise you purchase something with some more stamina. The minute you touch voltages on the CPU or GPUs, the power draw can rise real fast and extensively.
There are many good PSUs out there, please do have a look at our many PSU reviews as we have loads of recommended PSUs for you to check out in there. Let's move to the next page where we'll look into GPU heat levels and noise levels coming from this graphics card.
In this article we review the Gigabyte GeForce GTX 650 Ti Boost OC WindForce 2X with that OC for a factory tweak and the Windforce indicating a silent yet powerful two fan cooling solution. The product is customized with a new PCB, cooling and a few tweaks, it has 2GB of memory with both that memory and the core base-clock slightly overclocked. An tasty product at an interesting price in the lower segment of the mainstream market.
ASUS GeForce GTX 670 DirectCU Mini review
In this article we review the ASUS GeForce GTX 670 DirectCU Mini edition, a compact performance graphics card designed primarily for small form factor PCs with mini ITX motherboards. The dual-slot card measures just 17cm and features the NVIDIA GTX 670 GPU. ASUS has re-engineered the DirectCU cooler to fit small form factor cases. While shorter, it introduces a copper vapor chamber placed directly on top of the GPU for faster heat spreading and dispersal with 20% lower temperatures than reference GTX 670.
MSI GeForce GTX 650 Ti BOOST OC review
In this article we review the MSI GeForce GTX 650 Ti BOOST OC edition review with that OC for a factory tweak. The product is customized with a new PCB, cooling and a few tweaks, it has 2GB of memory with both that memory and the core base-clock slightly overclocked. Overall an interesting product at an interesting price in the lower segment of the mainstream market.
EVGA GeForce GTX 650 Ti Boost SC edition review
In this article we review the EVGA GeForce GTX 650 Ti Boost SC edition review with that SC for superclocked. The product is fairly reference looking but does come with EVGA's own styled cooler, it has 2GB of memory with both that memory and the core baseclock slightly overclocked quite significant.
