quik 3.3 volt?

ok i put a nice 400wt psu in a "A-1" was the brand on the box if i remember correctly. cost $100 .
works great except i get 3.23v @ 3.3v in mbmonitor
i do have alot running but not enough for a drop below the correct setting.now 4 my ?'s

whats the 3.3v line feed or run?
can it hurt my overclocks?
what effect will my watercooling have on this 3.3v?-it goes in next week-
how can i or do i need to fix it?

the rest my voltages are on the money! thank god!
i have a second 300wt as a backup if i need it but i dont wanna use it unless i have to since it will have to located outside my case. most my rig listed in sig.

u r fine as long at it is within 10% u should in very good shape. double check the 3.3 under load and if you are only off by 3% don't worry you machine will be solid.

kool ty so much!
yeh it stays at 3.23-3.21v under load
can ya tell me what is using this 3.3v line?
