First things first, I'm currently using a Cougar Power 550W PSU.
I overclocked my i7 860 from 3.55 to about 4ghz a couple months ago and received hard drive and memory failure.
I overclocked my i7 860 from 3.55 to about 4ghz a couple months ago and received hard drive and memory failure.
I reverted back to stock clocks and took a break from ocing after that because of work.
It sounds kinda like a mixture of this and this. The sound is barely noticeable to fairly noticeable depending on the current system load but also on the degree of overclock.
This is why I don't trust my PSU anymore. I don't know if its going to go bad soon or what caused this but I don't feel comfortable running it overclocked in this state. It's been running fine past 2 months at stock clocks/ volts.
I need the extra overclock performance though so I'll have to get a new PSU. I'm wondering if my PSU was possibly not good enough to run the aggressive overclock that initially caused hdd and memory failure. Here is a spec sheet of my PSU Series.
So I'm wondering what PSU to get that will provide enough power and stability to overclock to about 4ghz. I'm also not sure how that kind of overclock will impact power consumption and generally what to pay attention to when it comes to PSUs specially in context of ocing.
