cause i have 4 PCs at home, 2 of the pcs using 850W psu superflower gold, and the other 2 is superflower 650w gold and cougar 650w gold. these 2 PCs that use 650w seems to have motherboard broken down, both motherboard spoiled because of voltage, is it related at all having higher PSU is better. im from malaysia so many my electric current for my place isnt as stable, both motherboard z77pro asus and p67 msi was spoiled.
In response to "seems to be enough", I should say that it's much more than enough; it's overkill. The only reason for getting overkill is if you want ECO Mode to keep the fan off at all times. Even then, I really doubt you'll hear the fan at its slowest speeds.
If you had two GTX 980 Ti's, the only reason for getting a high-end 850W PSU would be if you were overclocking the cards.
I noticed you keep specifying "gold". It seems to me that you may be mentioning it as though its an indication of the PSU's quality. It's not. There's no reliable way to judge the quality of any PSU, really. However, even so, specifying "gold" when you don't know much about the PSU can help those of us who know the PSU models to know which PSU you're talking about. ;)
If you have unstable power coming out of your wall outlet, then you need to stabilize it before it reaches the PSU. It doesn't matter what you buy for a PSU, unstable power coming out of the wall outlet will hurt the PSU and thus it will hurt the entire computer.
Why "Gold"? I'm only asking in case you are trying to say that all Gold PSUs are high-end.
