Enter the In Win Commander series of power supplies. Designed with the enthusiast/gamer in mind, they promise to deliver clean, stable power while maintaining a high efficiency rating. We have been blessed with the opportunity to review the 1200W version, but they are available in anywhere from 650W all the way up to 1500W. For many users, 600W is more than enough. But there is a certain group, a rather large group, that believe too much power is never enough. I, of course, happen to fall into the latter group. Why settle for 600W when you can have 1200W? It can offer several benefits. Not the least of which is higher efficiency. Many users mistakenly believe that when they hook up a 1KW power supply their power bill will go up as a direct result. When you have a highly efficient power supply, however, you're not drawing any more wattage from the wall than you would with a smaller PSU, you simply have more room to grow.

So the question, then, is whether or not the Commander 1200W will provide that clean, stable power. Let's find out as we put the power supply through its paces!
