my pc have been shutting down randomly a lot recently... i thought it was some short circuit, i raised the whole board off the back of the case with additional screws, and i added plastic rings on the screws to avoid any contact between them and the mainboard.

sometimes it wont start. i turn it on by pressing the power button. it launches up momentarily then shuts down and launches again and etc. .... then after around 5 cycles of these it goes to Post but claims "the overclock failed" (though it worked before countless times even with higher values). and even with no OC it does that on-off thing and with no particular reason it turns on randomly.

i tried different combinations of ram sticks, no use.

i found some people on the net claiming that this can occur due to something called "motherboard hard cycle".

long story short what the hell is going on

That PSU is absolutely craptastic. Notice that the ratings ar efor PEAK output...it can't maintain those power levels for extended periods of time. Not to mention the fact that it appears to be a "500W" PSU that is peak rated for 216W on the 12V rail. Most power in modern PCs is drawn on the 12V rail by the CPU/GPU. That thing shouldn't be rated higher than a 200W PSU. What are you PC specs?

Agreed. It is not only junk, but it is totally unsuited for any PC built in the 5 years.

The best price/performance PSU on that site that meets your system requirements is the Antec VP550P: http://en.ksp.co.il/?uin=13633 Review: http://www.techpowerup.com/reviews/Antec/VP550P/
No frills but made by a top PSU mfr, Delta Electronics, for Antec. It's a little over your budget, but the HD6870 requires a PSU with two 75W 6-pin PCIe power connectors.

There is another possible option for you. The Seasonic S12II-430 is supposed to have two PCIe power connectors but the website you linked says their S12II-430 only has one. Here is a link to the Seasonic data sheet: http://www.seasonic.com/pdf/datasheet/NEW/Retail/S12II%... If you can verify with the retailer that the PSU has both PCIe power connectors then it is sufficient for your system, is under your budget and is an awesome PSU.

Glad I could help and thanks for the BA! I have the 520 version of that S12II and I'm running an HD6950 on it - cool, quiet, reliable power.
