Just recently, my wife and I had some friends over and, by the end of the night, we all ended up playing Tetris on the Wii. I must admit that I'm not a huge gamer but I do occasionally like to get in a round or two of a few different games, Tetris being one of them. If you have never played Tetris before, it is a very simple game, you try to create solid lines from falling blocks all of which are different shapes. A Tetris consists of four solid lines being created at one time. As you progress through the levels, the blocks fall faster and faster and it becomes increasingly harder to create the lines without any holes. I got to thinking that building a computer was sort of like a game of Tetris, there are many different components required to get a solid base system, just like Tetris. Without some very solid components, sooner or later it's going to be game over.
One of the most important components that most people tend to overlook is the power supply. When we look at power supplies, people seem to think that the wattage of the PSU is the most important thing you can look at. To a certain extent it will be, you obviously need a power supply that can deliver enough current to keep your system stable. However, you don't need to run out and buy a PSU that is 1500w, when say a 750 or 850w power supply will work just as well. This is when we turn to the 80+ certification on PSUs. There are a few different levels that we can look at to be sure we get what we need, such as Bronze, Silver, Gold and Platinum, and each incremental level requires a certain level of performance to get certified for each different class. As each class progression occurs, a few different things will occur, we hope; the level of power that is able to be delivered on a continuous level increases, as well as the cleanliness of the power. Lepatek is a subsidiary of Enermax and they have a full lineup of products from chassis to PSUs.
The Lepa G500 is a 500 watt Gold certified Power supply which will deliver up to 93% efficiency. The G500 Gold certified PSU from Lepa has three 12v rails that run at 25A each, a 3.3v rail and a 5v rail that both run at 20A a piece. The Lepa G500 is cooled by a 140mm fan, which should help keep the temperatures in check when you have your system running for extended periods of time. The G500 also has a slew of features, like Over Power, Over Voltage, Over Current, Short Circuit and Brown-out protection. The Lepa G500 is also a modular power supply, so it will help with any extra cable clutter, if you're using a SFF or Mid-Tower case.
