With most enthusiast/gamer PCs of today requiring plenty of solid consistant power to provide for a reliable rig, it's not uncommon for one to look at Power Supplies upwards of 700watts. With the mass of different models on the market though, it can sometimes be a little confusing as to which you should go for.
Tech Report come to the rescue with a huge roundup of quality Power Supplies compared ranging from 700 to 1000watts, these from well known PSU makers including Antec, Corsair, Gigabyte, Hiper, PC Power & Cooling, Super Talent, Tagan, and Ultra.
There was a time when the power supply was the most neglected component inside the PC. The PSU was an afterthought for most, usually a generic unit that came bundled with a case. And there it would sit, often not-so-quietly, entrusted with the important task of supplying power to other components that were usually chosen with far more consideration and deliberation. Over time, the odds that a generic PSU's voltage lines would start sagging were pretty good. If you were lucky, this would only cause system instability. However, in more serious cases, other system components could be damaged.
