Under this load, we start to see the power supply fan ramp up as well.After some time under load, we see our temperatures level out, an increase in the graphics cards' fan's RPMs and the PSU's fan leveling off just over 500 RPM.When we switch back over to the "Power" tab, we can see that our load has increased to 473.4W. Both of these parts have been replaced with DSP, which stands for "Digital Signal Processor". But since the information about the power supply in these older units was accumulated via the PFC/PWM controller and supervisor IC, the information had to be converted to a digital signal before being displayed. This information is also analyzed by the DSP's microprocessor and adjustments are made to the different components of the power supply in an effort to improve efficiency while maintaining very tight voltage regulation and minimizing ripple and noise. There are also check boxes that allow you to turn OCP on for the 8-pin +12V outputs (labeled "PCIe") on the power supply. RAIDMAX RX-450K Continuous 450 watts ATX 12V v2.3/EPS 12V Power Supply. ), the DSP still has the ability to act as a supervisor IC and shut down the power supply if any values exceed what is considered "safe" for the power supply or your computer.

Tutti i diritti riservati. Power supplies have attempted to deliver similar information about the power supply to the end user in the past; either via software or displayed on a 5.25" bay LCD. Today, we take a look at the Corsair Link 2 software, or just "Link" for short, and more specifically how it gives you the ability to monitor AC input, DC output, the temperature and the fan speed of an AXi power supply. Sometimes power supply from the electricity company is not static which might hinder the working and decrease the efficiency of your desktop, with this easy to us. Don't skimp on a PSU. AXi PSUs still use what's called a "resonant mode" topology like a lot of modern day super-efficient power supplies, but typically in other resonant mode PSUs a PWM controller IC changes the power supply's switching frequency based on an analog signal derived from the load measured at the transformer. Above is a supervisor IC found in a Corsair GS800 power supply. Since the DSP accumulates all of this information about the power supply, and does so in real time, we can deliver it to the end user via our Corsair Link software. The first thing I want to do is open up the "Graph" tab and set what I want to monitor in the "Config Panel" of this tab...Above, you can see that I've checked boxes asking to have my two graphics cards' temperatures and fans graphed, as well as my CPU's temperature, the temperature of my AX860i power supply, as well as the AX860i's fan speed. Copyright Because the signals are digital instead of analog and an inherently homogeneous DSP system is used to analyze the information as opposed to multiple ICs, adjustments can be made much faster than can be made with the typical set of ICs found in other desktop power supplies. We can also keep track of the temperature inside the power supply and how fast the fan is spinning:All in all, AXi Digital Power Supplies are so much more than your average desktop PSU on so many levels. The EVGA 450 BT Power Supply is here. Above we see two more ICs found inside an AXi series power supply. Today, I'm going to explain the functions of the components that are replaced within the Corsair Digital power supplies and how these changes benefit the end user.
