There is a video on YouTube , the man in the video says that modern CPU Consumes absolutely no watt at start up ~ 0 Watt ,
Therefor if you are using a PSU with ATX 12V v2.2 it won boot .
This Problem is solved in ATX 12V v2.3 PSUs .
How true is this statement .
I am building a pc with i3 3220 and GA-b75m-d3h , i read the manual of motherboard , there is absolutely no information regarding this .
also there is no strict rule , that if you are using ivy bridge you should use ATX 12V v2.3 PS.
I want to use My two year old PSU which is ATX 12V v2.2[ it has all required connector 24 pin,8 pin ,and other] with core i3 3220 and GA-B75M-D3H.
I have never seen something like this but i don't know.

So is it going to be problem or i can safely use it ?

Some form UPS's will not work with some PSU's with active pfc. Never use an UPS so not an expert on the matter.

and Corsair PSU webpage says "0.99 Active Power Factor Correction provides clean and reliable power"
checkout the webpage
I used to think that active pfc has to do something with input current ,
now what is all about reliable DC electricity .
DC power means electrons flows only in one direction , it hard to figure our which is unreliable DC current .
only parameters come to my mind are Current , Watt and potential difference
How to distinguish between two DC current i used to think that DC current is Universal now corsair says that there is something like
"reliable DC current " so there must be a " unreliable DC current " too . but the question is how to identify it ?

for me active PFC means :
1] no input voltage switch , a same psu can be used in different countries
2] and there is nothing like reliable dc power and unreliable dc power , DC current is universal

I shall update the post once i install the old PSU with no active PFC in it
