Thinking about power usage, it is important to remember how power is generated. In the United States, more than 50% of the power is generated by coal fired plants. What this means is that most of the energy Americans use is very dirty, compared to wind and hydroelectric turbines. Continuing down a path of using excessive amounts of energy will cause prices to skyrocket and the environment to deteriorate. This has caused many of us to think about efficiency, especially with regards to our precious electronic devices. Electronic devices tend to sip power even when not in use and some can draw a large amount of power when they are being used.
Desktop computers are one of those devices that, at times, can use massive amounts of power. This is especially true considering how common overclocking and multiple GPU systems are becoming. One of the ways this energy usage can be combated is by producing efficient power supply units. The efficiency is rated using the 80 plus system. Power supplies are given a certification based on how well they work. To qualify, a PSU must meet the 80 Plus standard by being 80% efficient at 100% load. Some PSUs do an even better job and a higher certification is given, up to the 80 Plus Platinum rating, which means that the PSU is 89% efficient at a 100% load using the system.
The LEPA G1000-MA 1000W power supply is 80 Plus Gold rated, meeting the strict standards for efficiency. The cooling system of the LEPA G1000 features a honeycomb mesh and a 135mm variable speed ball bearing fan to keep the PSU cool while maintaining low noise levels. Four independent 12V rails are provided, each with a max of 30A load, for compatibility with high end CPUs and GPUs. The G1000 has a semi modular cabling design. Hard wired cabling is present for the motherboard, CPU, and (2) 6+2 pin PCI-E cables. Modular cables are available to be used for additional PCI-E connections and storage/accessory connections. LEPA has designed modern protection circuits into the PSU as well, with Over Power, Over Current, Over Voltage, Under Voltage, Over Temperature, and short-circuit protection.
