It's not the loss of power that damages hardware, it's the power surges that may or may not accompany it. Loss of power can however corrupt data on your hard drive.

Yes, it is called a Uninterpretable Power Supply (UPS).

They vary from units that basically give you a minute or so up to several hours of run time. The basic ones are around $40. They are good for areas that have poor power with lots of surges and brown outs. The usually do not have software and hardware that allows the computer to shut itself off automatically.

Better ones have a USB plug that plugs into your computer and software (or Windows own settings) on what to do when the power goes out (shutdown, standby, hibernate, how long to run etc). They start around $60 for one that will last 5-10 minutes, up to several hundred for ones that last for over an hour.

APC makes some good ones for a decent price (as well as a few other makers).

My sister has some "dirty" power at her house. Her computer kept crashing and her HDD died. When I replaced the HDD, I added an APC UPS. It has software that tracks the UPS usage. Within 4 weeks she had over 30 instances where the UPS kicked in due to power problems (but she said the power never went out at the house).

I have 4 in my house. 1 on my sig rig, 1 on my HTPC, 1 on my server and 1 for my router and modem (I have Vonage, so this keeps my phone working in a power outage). Only the one on my server has a USB plug for the Computer and is set to shut down automatically once battery reserves get down to around 5 minutes (according to teh software, that gives me around 25 minutes of usage with the 450w UPS).

No, power supplies don't come with batteries, however what you're looking for is called a UPS (Uninterruptible Power Supply). APC, Tripp-Lite and Cyberpower are three big brands that sell those. APC is the big worldwide brand, not sure if Tripp-Lite and Cyberpower sell outside of North America. It looks like a big, heavy power strip. You connect your computer to it, and it can power a computer for a while, giving you time to shut down safely like you said. Just make sure to get one that's powerful enough for your computer.

Probably a n00b answer.
But for a power surge...isn't that what a surge protector is for?
the UPS's are all fine and dandy for a outage, but They aren't going to keep back a power surge? right?

Pretty much every UPS is also a surge protector (I have never seen one that is not, but that does not mean they do not exist).

UPS are actually better surge protectors, since you have both high and low surges, UPS can keep the power within a much finer range (my APC software allows me to define at what range the UPS kicks in, I think it is between 136v on the high end and 106v on the low?)

I wouldn't worry too much, most modern power supplies, especially your corsair have built in surge protection up to a certain point.

UPS's have built-in surge protectors so they will easily protect you from surges as well as power failures.

Welcome to the North East, lol, happens here all the time, Lucky the storm last night did not take out the power here at my place.

All you should need with stuff like that is a good Surge Protector if you don't mind loosing some data when the power cuts out, if you do then go with the UPS
