I've been trying hard to get my Q6700 to be stable at 3 - 3.2GHz But it didn't work my PC kept crashing everytime and i get OC failure even if i slightly overclock it (2.8GHz) it fails
i got a pretty cheap 500watt PSU (Dunno what brand)
Radeon HD 7850
1tb 7200 seagate hdd
C2Q Q6700 2.66GHz
8gb of ddr3 memory

i'm saving money to get a new 500watt+ PSU soon Can anybody tell me what should i get?

Thanks.

Yes, cheap psus can make your system unstable and are not recommended for overclock.
Another source of problem could be the temperature. Are you using an aftermarket heatsink?
Anyhow, you should probably do a little more researching before going into the overclock realm. It looks like you do not have much knowledge about it or did not tinkered enough.
About the new psu, there a plenty of good power suplies. look for 80+ certification at least or reputable brands such as seasonic.

Yes, a cheap PSU can cause overclocking failures as overclocked components require more power to run. In terms of recommendations:
Seasonic S12-II 520W 80+ Bronze Certified Wired Power Supply
XFX ATX 550 Power Supply

Before I knew better, I overclocked my PC on a cheap, old, no name power supply.
The PC ran OK for a year, but predictably, the power supply failed (with no damage to any other components, +1 to Asus motherboards!)
I replaced it with a better, more respected brand.
I had another go at overclocking, and the new PSU made almost no difference.

If you have problems overclocking, possibly you are doing it wrong... but most likely you have got a CPU that doesn't overclock well.
It has happened to me a couple of times.. I have a 3570k which only goes to 4.1GHz, but according to the internet 4.5Ghz is easy on these CPU. I also have 2 Phenom II CPUs, one at 4GHz, the other maxxes out at 3.45GHz

Power supplies are the heartbeat of your computer. A cheap one is like having a bad heart: it can skip a beat, pump too hard or pump not enough, wreaking havoc on the rest of your internals. Computer components need a PSU that delivers stable voltage performance across a wide range of power needs (measured in something called "ripple"). The biggest no-no you can ever do when building a PC is go cheap on the PSU. An extra $20-$40 on a better PSU is an insurance policy on the PC.

But to answer your question, anything from Seasonic, Corsair (stay away from their low end CX series), and EVGA and you cannot go wrong. Also get a Bronze efficiency rated one if you are on a budget.

What do you think about this "Corsair CP-9020097-WW VS550 VS Series 550W" is it good?
