I7 2600k PSU ???

[fissi01]

Hi guys ! I am almost building my gaming rig but there is just a detail that i'm not sure about

Here are the specs :

ASUS Maximus IV Gene-Z
Intel Core i7 2600k 3.4 ghz
ASUS Radeon HD 6870 915mhz
Corsair Vengeance 8GB DDR3 1866 Mhz
ThermalTake Element V Full Tower Case

I have chosen as PSU , Corsair TX Series 650W but i'm not sure that it will have enough power for my system.
What do you suggest to me guys ???
650W or 750W (maybe i'll overclock cpu to 4.2ghz) ?
Thanks!

Should be plenty. My 2500K @4.4G and HD 6850 aren't even pushing my 550w.

I would get a 750 for future add on.

I kinda like the Antec High Current Gamer Series HCG-750 750W , its a pretty good deal with the back to school savings. It should work great for you.

EDIT: Im not sure, but if your not going for a High End computer or professional design, the Intel i5 2500k CPU would be the best choice

Even though you're using a Corsair PSU you could use the Calculater on the MasterCooler site to calc your power requirements. Should be fairly accurate.

The best PSU calculator: http://www.extreme.outervision.com/psucalculatorlite.jsp

Takes into account OC, drives, capacitor aging, system load, etc. Don't use the simple calculators.

Use 30% capacitor aging and 100% system load just to be safe. even plug in your OC. Let us know what you get.

Btw, you can't go wrong with seasonic or corsair PSUs

The i7 is not better for gaming. The only difference between it and an i5 is that it has hyperthreading (and a slight increase in clockspeed, which can be more than made up for by OCing, I haven't seen any evidence than an i7 can OC better than an i5 btw). As games rarely use more than two cores hyperthreading will have no impact, unless, maybe, there is a lot of multitasking going on.

A good OCed i5 is way better then a i7 in gaming.
