When I on the computer the power goes on then off then back on and runs normal?

post #1 of 4
Thread Starter 
Hi everyone, I'm sorry for the long thread topic. I'm not sure what is the problem here but this is happens most of the time or randomly but I don't see any problems with it and I still don't want to take advantage of it.

When I on my computer the power goes up then down for a few seconds then gets back on and runs normally. Its like trying to take some power first then go back up.

Have you heard of this problem?
People told me that its not safe to use a bad power supply also when overclocking it might just burn. But since my power supply is quite big for the components I have I overclocked it few days ago and I don't find any problems not unless I have a power hungry graphic card. Besides I'm going to get a new power supply at the end of this month.

I might go with the Corsair HX650 or something with a reputable name and any recommendation is appreciated.

Thank you.

I had this problem before, it was with an older Thermaltake 850w PSU in conjunction with my MSI motherboard...

Much research later I discovered that back in the Prescott days a mobo manufacturer incorporated an "onrush current fault protection" scheme to protect the cpu, what this does is inhibit the high current that is applied from a PSU to the mobo to avoid damage... once the PSU capacitors/mobo caps charge up and fall within a certain limit, the machine post.

This fault protection, is not really a feature but has been copied weather knowingly or not by many many current mobo manufactures and I have seen it on Gigas, MSI, ASUS... and others...

I solved the problem by purchasing a better PSU with newer features... as it goes with PSU's most (90%) are based on reference designs, normally in china, and rebranded by your various dealers... TT, Corsair, NZXT, so on and so forth... making them mostly the same... short answer... PSU is to blame.

Thanks that is some good information. Didn't want to quote the whole thing to make the thread shorter for others to see. You deserve a +Rep.

Just trying to save you some time, probably you have this issue if you shut down dicker with things in the case, and plug back n' power up, or after the thing has sat for awhile...

If you like Thermaltake, and I happen to, take a look at the Toughpower XT series... http://www.thermaltakeusa.com/Product.aspx?C=1264&ID=1943 this is the 775w that I exchanged that 850 with, and it is great for my purposes. They have some a 600ish one too... but for the most part anything that is...

Compliance with Intel ATX 12V 2.3 & SSI EPS 12V 2.91 standards.

High quality capacitors, solid state capacitors

Built in industrial-grade protections: Over Current, Over Power, Over Voltage, Under Voltage, and Short-Circuit protections

That last one is were your (our) problem is/was. Thanks 4 rep Cheers!
