Yeah i guess i could run this whit the 120
Actually it aint. Manufactuares always notice the recomended power sourcer wayyyyyy higer than its actualy needed and it always depends the guality of the power source too. 350W 80+ Can easyly beat some recular 600W cheap powersource it aint the amount of the power itse guality of it! http://extreme.outervision.com/psucalculatorlite.jsp is good site to check how much you really need power. I am running Q8200 quad oc 3..37GHZ from 2.4 and this gtx 670 and 8G DDR2 and 4 normal S-ata HD and so on just fine. All oc so high than they can go
Actually you'll be surprised to know this,
80+ certification is about how much efficiency your PSU has. And not about how good it is to deliver power. Although it relates to both.
Here it is in my own words:
A cheapo 600 watts PSU can push out barely 600 watts. But in return, sucks up more than 600 watts from the wall socket. Thus low on efficiency.
It may also have poor power/ripple regulation. Thus low on output quality.
But it is so wrong to say your 350 80+ gold (or platinum) rated PSU to push out more than a 600 cheapo true rated PSU. Remember that's almost twice the deficit. And PSU's were not built to double their power ratings..
Also note this, PSU ratings were actually derived from their efficiency curves . So while your 350 gold certified may be cleaner to deliver power at it's optimal EFF curve, it still cannot topple the output of a 600 watts cheapo which has a lower or less than acceptable EFF curve.
Then there's ripple regulation.
Ripple is not voltage drop just to clear this out. It's a form of voltage distortion with a certain frequency that may either go higher or lower than the value of a desired PSU output voltage.
An ideal PSU has no ripples. But they're non existent in electronic world.
While it may be good to point out that 80+ certified PSU has a good ripple suppression, you should also know that ripples were not as big as 1 volt. Or some milivolts in computer PSU speak. Thus still giving a cheap 600 watts an edge over your 350watts 80+ gold.
Then, why the hell do we need to purchase an 80+ certified PSU?
It could mean savings, it could save the earth, it has better efficiency curve, it has less ripples and it is safer on the components because of their clean power output. But that's just about it.
It cannot and will not produce magical outputs that were higher than it is rated for. Period.
On the context of your OC'ing, you may have considered your cpu TDP value, your GPU power consumption ratings, and you overall system added together. But you may want to check and consider that overclocking does not produce a linear relationship to power consumption. A CPU oc'd by about 20% will consume more than 20% of it's normal power consumption.
That is because the frequency increase (more on states per second = more current) and it being subjected to a much higher voltage.
So you should consider that when choosing a PSU.
Another thing, TDP is not power consumption!!
And one last thing, electronics is now more concerned about low power figures. This is now the name of the game. So again wrong point to say they rate them much higher than they actually consume..
