power supply

Who uses a UPS  (Uninterruptible Power Supply) on their computer still? I got rid of mine a while ago and just bought really good surge protectors. Who still uses one, and do you recommend a certain brand over another? APC, Cyberpower, Tripplite?

Linux workstation didn't want to power up after returning last evening. Got it to finally power on and went into the bios. 12 volt rail was reading 10.2 volts. If I keep messing around, the motherboard will be next. 

I thought I would post this here since there wasn't much on the internet about it and in case someone that stumbles across this post has a problem like I did. So I got a new power supply for my computer yesterday. Removed my old one and installed the new one and did all my wiring nice and clean...

So I was on my main computer this weekend, and all of a sudden it just shuts down. Kinda fades to black slowly. I was like hmmm. Whats going on. All of a sudden smoke starts to rise out the back of the system. I grab the power cord real fast and unplug. I hate that smell of a burnt power supply...

Must be at least 500W, 36A on the 12V rail, lastly I want a modular power supply since I am putting it a small case. Thanks in advance.

I thought this may be a useful tool for some of you in the future, so i put it in here. http://www.extreme.outervision.com/psucalculatorlite.jsp
