I have a friend that say's he can overclock my I7 920 to 4.2ghz and have it be stable. However I question my power supply and I am not sure if there's a issue with me running tipple channel ram at 12 gigs. I don't know much about overclocking and I was hoping to get some input from some people on here and if anyone would recommend anything.

My power supply is Rosewill 750watt 80 + Certified

COMPUTER SPECS

Cooler Master haf 922 Case with 5 fans total
I7 920
Corsair Liquid cooler
60 gig solid state drive
1tb drive

750 watt Rosewill power supply 80 + Certified
12 gigs of Mushkin Enhanced Black Line 7-7-7-20 1.5-1.6V 998677b
Motherboard MSI x58m
WINDOWS 7 64bit

CURRENT TEMPERATURES WITHOUT OVER CLOCK WITH CPU USAGE AT LESS THEN 3% Not sure if speedfan is correct so I used two temp program readings

Core 1 37C SPEED FAN SHOWS 21C
Core 2 36C SPEED FAN SHOWS 14C
Core 3 29C SPEED FAN SHOWS 14C
Core 4 29C SPEED FAN SHOWS 21C
Core 5 36C SPEED FAN SHOWS 21C
Core 6 36C
Core 7 35C
Core 7 35C


Will I be ok with this power supply and do I need to do anything special. Such as new heat sink on my Corsair cooler or is my current setup good to go?

First of all, you do not know for sure that you can reach 4.2 GHz. All CPU's are different. It is pretty likely, but you just do not know.

Second, idle temps are useless for overclocking. You need to put a 100% load on the CPU and test for stability and max temperatures.

Third, Rosewill PSU's are decidedly mediocre. Your power capacity is more than adequate. I'm just not certain that the quality is.
