If you’re serious about protecting your PC—and any unsaved work or game you might have open on it—you need an uninterruptible power supply (UPS). A UPS is a surge protector and emergency battery in one, meant to keep devices safe and humming along when the power goes out. Right now, Newegg has a particularly good model on sale: The retailer has dropped the CyberPower GX1325U to just $125. That's $65 cheaper than the going price at other retailers.
