Powering your computer can be a complex matter, especially considering that machines range from powerful gaming beasts to simple home and office mainstays that power personal businesses. Over the years the world of computer power supplies (or the PSU) has grown steadily; some units are now even able to produce voltages in excess of 1500 watts. As this is one of the most important components in your PC, you want to consider all of your needs when purchasing a power supply, especially when building or powering a computer designed for gaming.
There are a bevy of trusted power supply brands. Though there are many smaller companies that create equally reputable hardware, some known brands to look out for are Corsair, Thermaltake, EVGA, and Seasonic. When selecting a power supply to provide wattage to your gaming computer, make sure that you make these considerations; as having a sub optimal power setup can hinder your gaming experience considerably.
• Remember, high end NVIDIA and Radeon graphics cards are notorious energy hogs. For an optimal gaming experience, try to stick with a power supply that’s above 500 watts. If you are planning to utilize SLI architecture and use two or more high-end, overclocked graphics cards, then you definitely want a PSU that offers a wattage that’s over 1200.
• No one likes a case that’s packed with wires that lead to no active computer components. Nowadays, there are many modular options that will reduce the number of wires needed to run your computer efficiently.
• If you’re looking to save on your monthly electric bill, select a PSU that is efficient as well as powerful. In 2004, the 80 Plus efficiency ratings were launched. This is a voluntary rating system that certifies whether a power supply operates at 80 percent efficiency at 20, 50, and 100 percent of an energy load. Efficiency ratings range from 80 plus to 80 plus titanium. One caveat: Higher energy levels tend to reduce efficiency, though this is not always the case.
• The sad truth is, as a result of load and some environmental factors like dust, PSU’s will eventually fail. Be sure that when you select a power supply for your gaming beast of a system, that there is a warranty in case it fails.
• Connector types are also incredibly important. Buying a PSU that doesn’t match your mobo (motherboard), can really be stressful. Be sure that any modular or even non-modular PSU you buy matches your gaming system’s connection requirements or you’ll have to buy another mobo or power supply.
• Also consider Over Temperature Protection (OTP) when purchasing your PSU. This feature insures that your device will shut down rather than burn out under load.
Here is a list of some of the best units for gaming on the market, grouped by the premium, mid price, and most cost efficient models.
The Best Premium PSUs for Gaming ($150 and up)
The second of our premium PSU’s garnered a bronze status for the 80 plus efficiency ratings, and while this isn’t quite as efficient as the Corsair AX1500i, bronze status still means that this is a very efficient power supply.
