The Power Supply Unit
We take a closer look at one of the least appreciated components and how it supplies electrical power to the other hardware devices. In further detail this article offers advice and information about PSU that power gaming computers with complex hardware setups and advanced power settings. Here is an overview.
The Power Supply Unit is an essential component to a gaming desktop computer. It powers select components directly, such as the optical drives, secondary storage devices, case fans, and the motherboard in order to keep everything actively operating. PSU vary in two 
forms, sub-standard units, not to important to this article, as its pertaining to gaming systems. The other variant can be generalized as an advanced PSU, with more applied technology involved in its features. Below are more references to gaming oriented power supply units and their core features.
Power Rating
Through its connection to the motherboard, your PSU posseses the ability to power your gaming system on or shut it off when needed. The important specification regarding power supply units incorporated into gaming computer is the "Power Rating." Computer power supplies are rated based on their maximum output power. Power supplies used by gamers and enthusiasts mostly range from 450 W to 1400 W. Typical gaming PCs feature power supplies in the range of 500-800 W, with higher-end PCs demanding 800-1400 W supplies. When reading specification on power rating, know that these rating are not certified with any third party company and all standard settings are based off of each manufactuer. Purchasing you gaming PSU may contradict other hardware purchases, such as the motherboard because of both of them working simotaniously to generate and supply power to the other components effectively and efficiently. If you have questions based on certain power supply unit, then consider contacting the manufactuer of that product to gain further detail about its rated power and performance.
What PSU Wattage do you need for gaming?
As all hardware components have different variations and versions, they all have specific power settings, and determining what wattage you need isn't a difficult decision. You can use the website to help narrow your search through Antec.com
PSU Form Factors
Power supply units have two basic models that can be found on the market. AT and ATX power supplies, or AT stands for Advanced Technology when ATX means Advanced Technology eXtended. ATX is considered a tremendous improvement over AT, resolving many annoyances. Consider purchasing an ATX PSU for gaming systems.
PSU Connectors
There are a few extranious wires connecting to the back of the PSU. Some come standard, but others are used for added features depending on how advanced you want your power supply unit to be. The general connectors include the newer 24 pin ATX motherboard connector, older 20 pin AT motherboard connector, or PC Main connection, the CPU 4 - 8 pin power connectors, the six pin and eight pin connections being suitable for high-end gaming motherboards and processor. Video cards utilize 8 pin PCI Express power cable connectors specifically built for graphic cards. There are three more important connection source, which would be optical drives, PCI-E, and SATA hard drive connections. The type of connection needed to accomodate the SATA and Optical devices would need to be compatible with the SATA connector interface, featured on many modern connection adapters. The PCI-E would be used for advanced devices, such as video cards for precise performance.
Lets overview what we have discussed. Power rating, form factors, and connection type should be evaluated in your purchase, specifically for gaming technical specifications. Please refer back to any section to get details on gaming power supply unit specifications.
