View Thread: why don't power supplies come with a built in UPS?

    @SteveRichter: if all you want is your PC to survive a power glitch in the split second range, you could theoretically just use a simple circuit that adds large capacitors on the low voltage lines of your PSU; the problem is that handling the "Power Good" line properly may not be straightforward.

    My advice: get a laptop.
