Power Supply Issue?
Sometimes im workin away on my comp, and all of a sudden, the comp restarts. No warning, no nothing. Just the system beep of the comp restarting.
Is it possible that the computer needs more than the 550 watts of power that my power supply is rated for, and because of this, it reboots? I'm nearly positive that its not a linux issue (running ubuntu) because there is nothing in the logs about the computer needing to restart.

My comp is far from average.

Having it restart by itself doesn't mean that the power supply isn't powerful enough. Usually that means there is something wrong with the power supply itself. How it delivers power, conditions power, etc. A 550 Watt PS is a pretty powerful. If you have the ability to swap it out for another one try that and see if it does the same. If it doesn't, you've found your problem.

What brand of power supply do you have?
It might say 550w, but the cheaper ones will only put out that kind of power under PERFECT conditions (temps < 30c).
I would agree that with a QUALITY PSU (enermax/ocz/thermaltake/etc...) you will be okay with 550...
On that note, I would NEVER, EVER spend less than $100CDN on a power supply... (in that price range you get modular ones, MUCH less cable hassle
)

I hope for your machines sake that 254.0 is because of an incorrect multiplierCode: Select all

p.s. this doesn't rule out that it could be a software issue.. if your kernel has a corruption, or perhaps a module/driver missing it would quite easily just die and reboot. Might be worth fsck'ing your disks for bad sectors, too.

That's 100% true. I tried 2 different cheap 550 watt power supplies, $20 and $45. They claimed 550 watts but when you really looked at the specs the amps just didn't add up to 550 watts. What they were rating the power supply at was 550 watts at PEAK. This means the maximum the power supply can put out under extreme load for a SHORT PERIOD OF TIME. Most of the cheap 550 watt power supplies are really around 350-400 watt. They are just uplabled for what they can put out at peak.nickvd wrote:What brand of power supply do you have?

It's pretty hard to find a decent 550 watt power supply under $100. A decent one will have multiple 12 volt rails to provide the most stable amp and voltage output. A single 12 volt rail power supply is stressed too much and they tend to fail fairly soon with extended use. The voltage converters just slowly burn themselves up. So you start having problems like random reboots, hard drives that make clicking noises and start having read/write failures and other odd things.
If you need a 550 watt power supply spend the money for a really good one.
