Computer keeps shutting off- PSU problem?-Please Reply!

I have a rig I just built. I am running an 6-core fx 6300 and a 7770 ghz edition, an hp ssd and 5 fans. I'm using a logysis 550w power supply. For some reason the computer randomly shuts off every few hours. It is plugged into a surge protector along with an AOC monitor. My guess is that the outlet isn't giving off enough power to the surge protector. I've tried switching to voltage on my power supply from 130v to 230v but no change. When the computer shuts off I have to unplug the monitor from the surge protector in order for the computer to turn back on. The power supply is weak, but shouldn't it run this? Someone said some 12v line had a output around 300w, but isn't this 550w? I'm not a computer geek but I know what I'm doing. I may order a better PSU. Advice on what to do please. Any help is appreciated. Thanks

EDIT: I do NOT have windows. I'm getting it soon. The crashes happened on Ubuntu Live 12.04/12.10 <---- something around those versions

I don't remember but I think it crashed in the bios too.

  1. 500-550 w is the minimum for that config. However, you have a very cheap psu there. So, I definitely think that could be the problem. However, before you order a new psu, have you checked your cpu temps? My brother was getting that very same behavior and his heat sink was not attached properly, leading to overheating and shutdowns.
  2. Yeah. My CPU when on minecraft on Ubuntu didn't get above 45 Celsius. Is that high? No components are getting hot. I have 4x120mm fans and a 200mm fan.
  3. Did you try a different outlet? Like, on a different circuit breaker? See what happens and tell us.
    Also, what happens if you plug the system directly into the outlet, leaving the surge protector out? Maybe it's the surge protector that's defective.
    You need to leave the PSU's settings at 110V, as well.The transformer drops the voltage in the secondary according to the selector. If it thinks it gets 230V, it will drop it even more to reach the nominal voltage in the secondary.
  4. The Logisys PS550E12BK PSU is rated at 400W continuous and 550W peak power.

    Graphics card manufacturers give their minimum power supply recommendation using a continuous power rating.

    Since it's doubtful that the Logisys PS550E12BK PSU is even able to deliver its rated continuous power that is most likely the cause of your system instability.

    Troubleshoot with a better quality PSU. Borrow one temporarily if you have to.
  5. I haven't tried a different outlet. Before I started using a surge protector it still did it. Before I used a monitor And ubuntu (just had the system run without anything attached) it worked fine. But there wasn't much power needed to do that so that's why I think it's the PSU. Sorry if that was confusing. Ill get back to you later. Thanks.
  6. Well, if it just randomly shut downs I hardly believe it's related to overheating or a general lack of power. Did you exercise some load tests? If so, what's the results? If not, I would do this next, as it will help to bordering the potential causes. Also you might want to monitor the voltages.

    Be aware, if the PSU is faulty for example, every startup and/ or heavy load may cause Damage to your electronic.

    I don't know this particular PSU, but it seems quite cheap and if I read the customer Reviews on Amazon, I probably wouldn't buy/use it.
  7. Yeah your temps are good. Try house70 and ko888's suggestions. Looks like it is leaning toward a psu problem.

    no the issue is that psu i bet, it is 500w, but the 12v rail is only 25a, that's really low. 5 fans alone will take up 2-4 amps by themselves, so 25x12 is 300W and your cpu twp is 95W plus and your 7770 is around 100w top usage so that's over 2/3rds your ideal usage, depending what on how many hard drives you have and if you're overclocking, you're pulling too much power for the psu to handle.
    a cheap upgrade that will do the job is:

    but if you want to be able to lets say get another 7770, or a even better gpu or anyother upgrades id recommend:

    Actually, overheating and general lack of power can both cause random shutdowns easily...any sort of hardware instability can cause random shutdowns.

    Both better choices than your current psu!

    Personally I would go with the second one here. A fair amount more than you initially spent, but you will never have any power issues.

    @HillBillyAsian love your handle :)

    If it's overheating it won't shutdown randomly, it will specially shutdown under load.
    If the PSU just generally lacks power, it won't shutdown randomly, it will shutdown specially under load.
  12. Thanks. I'll get a new PSU

    not true, not all mobo's and cpus are made the same, that saying, they all won't go into a reboot cycle if its over heating or just shut off, some after shutting off and you try to turn it back on it starts for a few seconds then shuts off others will do a full boot then shut off. Besides, with electronic degradation i'm betting his psu wouldn't last over maybe 1-2 years before it wouldn't be strong enough to power the system considering how weak it is.

    wise choice, keep that old psu around just in case you never know when you'll need one lol

    Both of those cases are very much subject to the situation. If a heat sink is not installed correctly, it does not have to be under any load to overheat and shutdown. I've seen this happen.

    If a power supply is cheap and cannot output the the constant amount of power needed to keep the system running...it can shut down, even without extra load on the system. I've seen this happen too.

    The system does not always have to be under crazy load to stress the hardware. Just sitting idle there are constant fluctuations to the load on the components. If a component represents a weak link then the "danger" can be constant. If things aren't stable, they aren't stable. Granted, putting something under a heavy load will bring these issues out much faster. That is the very reason we stress test our overclocks...to see if they are stable. But, if the system is not stable a crash can happen at any time.

    Sorry for getting long winded and somewhat sidetracked in your thread Bfrancom! :) Good luck with the new psu!
  17. I'm gonna buy a new PSU. Heatsink is in correctly. CPU isn't getting hot at all.
  18. Please let us know what happens after the new PSU is in place.
