Everyone knocks the MSI boards, but I have been around the block now and I have pushed those MSI boards back in the Phenom 945 days and nothing happened. Maybe I got golden ones but still, none ever failed even hitting 1.6v for long periods of time.

There is no such thing as 100% failure rate. But there is such thing as increased failure chance:

http://www.overclock.net/a/database-of-motherboard-vrm-failure-incidents

It's a bit like this. I 've been using Asrock 970 extreme3s since the Bulldozer era and keep using up to 4Ghz. I know people that push them to the last stable clock (from 4.3 to 4.4) and the board survives. Would i advice that to others though? No, because the motherboard isn't made for being pushed hard.

The problem with motherboard failure, is that it is an "all or nothing" failure. When it fails, it will most probably fail due to VRM failure these days. With the unfortunate eventuality to kill the CPU in the process. And nobody likes his CPU burnt...which is why it's better be safe than sorry.

Granted i take what i read with a pinch of salt but supposedly the 970 gaming board is meant to be a bit better than previous similar msi boards in the VRM area. Still uses the nikos fets though.

Is the main culprit of failure excess heat? As it stands now at 4.9ghz and 1.55v with the little monster of a fan i have blowing on the northbridge and vrm heatsinks the northbridge sink is cool to barely luke warm and the VRM sink is only barely luke warm. Both were much hotter without the fan at default settings and default clock speed.

Are you literally touching the heatsinks to determine their temperature?

If so, I would suggest doing hardware monitoring with the extended version of HWINFO that provides VRM temps.

Sell that low-grade PSU and replace it with a low ripple unit. I would not recommend the noisy EVGA G2 850 watt unit, though.

BeQuiet makes an excellent Dark Power series. The key with power supplies is that Seasonic units in particular tend to be paired with 120mm noisy ball bearing fans. There is so much enthusiast obsession with low ripple, high efficiency, and good regulation but not enough focus on preserving one's hearing. Tinnitus is no joke I assure you. You want to find one, like BeQuiet, that uses a low-ripple platform like Seasonic or Superflower with a 135 or 140mm fluid bearing fan. Corsair makes some expensive PSUs that fit the bill as well. There are other new platforms that should be good, too, but if it comes with a good fan (like BeQuiet) you can't go wrong with a Seasonic platform model.

Yea was touching the sinks. I have a little 3-4500rpm ish AVC cpu fan blowing on nb and vrm sinks now and they remain cool to luke warm to touch. Im also using cpuid hw monitor. Passed 10 runs of ibt avx on very hard at 4.7ghz with half decent temps that way. Though for the burn tests i ended up borrowing an 80mm cpu fan to blow on the back of the mobo to cool the cpu socket as without that socket temps would steadily rise into the 80c+ range. With the fan i was able to hold in the mid 60's. Cpu temps and all other temps were below 40.

Regarding psu... List me off a few 1000w units that are good. I can always throw the corsair in a rig i build to sell at some point.

I would buy a SuperFlower Leadex any day, they are wonderfull PSU's.

Also go and spend 10-20$ on a IR thermometer, you can have lots of fun with it and monitor your chokes and caps temperature. A general rule for capacitors is that they are rated for 3000h at 105C and for every 10C below that their life doubles.

Actually have an IR thermometer somewhere.. Can also stick a little k type probe on it as well. I run the fan on the VRM/NB sinks at about 80% normally or all fans on full if im pushing the system. Heatsinks stay far cooler than even default clock speed/vcore with no fan. I can OC as far as i dare and those sinks stay cool or luke warm with that little monster of a fan on them.

I would have strongly suggested the Dark Power Pro 10 series but now BeQuiet has switched from Seasonic to FSP for the Dark Power Pro 11 series. The 850W unit does very well in reviews but the 1000W model is a bit less impressive. If you're going for an 850W unit then I would definitely recommend the Dark Power Pro 11 but for higher wattage I would look elsewhere. However, noise is still an area where even the 1000W did well.

The main things to look for:

1) 135mm or 140mm fluid dynamic bearing fan
2) outstanding ripple
3) excellent load regulation
4) excellent transient response
5) Japanese caps if there are liquid caps

The Dark Power Pro 10 psus even had a server-grade Yunpen line filter.
