چه جالب! هسته دوم منتظر میمونه که هسته اول بهش کار بده تا کار کنه! از عجایب روزگاره. :laughing:
عجیبتر اینجاست که SLI اصلاً به درد نمیخوره =))
با اجازه صاحب تاپیک، مصرف کارت رفرنس: Power ConsumptionLet's have a look at how much power draw we measure with this graphics card installed. 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 test system is based on a power hungry six-core Intel Core i7-3960X Extreme Edition Sandy Bridge-E based setup on the X79 chipset platform. This setup is overclocked to 4.60 GHz on all cores. Next to that we have energy saving functions disabled for this motherboard and processor (to ensure consistent benchmark results). We'll be calculating the GPU power consumption here, not the total PC power consumption.
Power Consumption
System in IDLE = 137W System Wattage with GPU in FULL Stress = 624W Difference (GPU load) = 487W Add average IDLE wattage ~20W Subjective obtained GPU power consumption = ~ 507 Watts
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 not a precise measurement, albeit a very good one.
Above, we have 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 either. Power consumption TDP in KWh KWh price 2 hrs day 4 hrs day Graphics card measured TDP 0,507 0,23 0,23 0,47 Cost 5 days per week / 4 hrs day € 2,33 Cost per Month € 10,11 Cost per Year 5 days week / 4 hrs day / € € 121,27 Cost per Year 5 days week / 4 hrs day / $ $ 160,08 Here is Guru3D's power supply recommendation:
AMD R9-295x2 - On your average system the card requires you to have a 850~1000 Watt power supply unit.
AMD R9-295x2 Crossfire - On your average system the cards require you to have a 1250 or higher Watt power supply unit as minimum.
