The Lian-Li Silent Force 750W will provide what most PC users want, stable rails with low noise, up to its rated maximum power. The efficiency, although very good, is borderline as far as 80 Plus certification is concerned and at one point we get a power factor that dips below the required level of 0.9. If efficiency and power factor aren't top of your list of requirements then this power supply will easily run all dual graphic card configurations with ease and is on par with other power supplies in its class.
