Sparkle Cases & Power Supplies

It began with the ENIAC, a 30-ton monster about the size of a railroad freight car that probably needed a locomotive as a power supply. In the six decades since ENIAC's birth, electronics, especially computers, have changed, and changed often, mostly for the better.

Modern computer power supplies come as an internal power supply for desktop computers or AC power adapters for laptops--both of which can wear out--plus batteries for laptops, which don't recharge forever. When this happens, your power supply needs replacement. Likewise, adding new computer components can also spark a need for an upgraded power supply.

In addition to internal power supplies, Overstock.com offers surge protectors and uninterruptible power supplies (UPS). The personal computer is a vital part of most small businesses, homes and individuals. We can't do without our PC. That means a UPS is great thing to hook to your desktop computers (or laptops when they are plugged in at home or your office). In case of a power failure, the UPS kicks in, giving you a few minutes to power down your computer system properly, rather than risk losing data and shortening the life of your power supply. If you ever travel internationally, you'll also need a universal power adaptor.

Fortunately, Overstock.com has a boat load of computer hardware, including a variety of power supplies that'll keep your computer--and your wallet--happy.
