Today Corsair introduced the AX1200i power supply it had announced at Computex. This isn't just any power supply, it's the first PSU for high-end desktop PCs to use digital control. The DSP is supposed to ensure extremely high efficiency and very low ripple values. It also comes with interesting features such as the ability to monitor and adjust vital parts of the PSU with software. Visit Upgrade Advisor.
A very impressive new desktop PC power supply is on the market, called the Corsair AX1200i. Why is it so impressive? It's the first PSU for high-end desktop PCs to use a digital controller. The DSP is supposed to ensure extremely high efficiency and very low ripple values. It also comes with interesting features such as the ability to monitor and adjust vital parts of the PSU with software. Hardware.Info took a closer look to find out how well the AX1200i performs.
Traditional power supplies have analogue components for regulating the voltages in order to keep the efficiency as high as possible. Corsair is the first to implement a DSP (digital signal processor) in a desktop PC power supply. Corsairs claims a DSP is faster and more accurate, which should results in extremely low ripple values
The manufacturer promises ripple values less than a third of the maximum ATX specifications. Low ripple rates mean stable voltages, which in turn make a PC run more stable as well.
The faster and more accurate working of the DSP along with the absence of various analogue components also lower the amount of energy consumed by the PSU itself. The AX1200i is 80 Plus Platinum certified, but Corsair claims that the power supply is more efficient than (almost) any existing 80 Plus Platinum models.
Corsair has proven with the AX1200i that it's possible to innovate even with relatively boring components. It’s done a great job with the AX1200i power supply, it’s extremely efficient and very quiet.
