i know how there are issues with the sandy bridge motherboards but i have decided to buy one with a i5-2500k cpu......i only have a hard drive and dvdrw so i will be fine using the 2 sata ports that work right........and if i need more i will just get a pci card for the sata ports.....and my question is will the psu that im gonna buy power everything even if its overclocked as much as possible........

asus P8P67 Pro motherboard

intel i5-2500k cpu

NZXT TEMPEST EVO Crafted Series TEVO-001BK Black Steel / Plastic ATX Mid Tower Computer Case

SPARKLE SXX4601024D5UNM GeForce GTX 460 (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card

Antec EarthWatts EA750 750W Continuous Power ATX12V version 2.3 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC ...
or any other 750w psu

G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL8D-4GBRM

Seagate Barracuda 7200.12 ST31000528AS 1TB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive

LITE-ON 24X DVD Writer Black SATA Model iHAS424-98 LightScribe Support

COOLER MASTER Hyper 212 Plus RR-B10-212P-G1



i just wanna know if the psu will have enough power even if everythign is overlocked to the max..........if the cooler will fit fine in the case and if it comes with its own thermal compound

Yes, a 750W PSU will power all of those components. Although that PSU may not be able to handle a second GTX 460 down the road.

The Hyper 212+ should fit (other users of that case reported using the Hyper 212+ in it) and that cooler does come with thermal paste, at least mine did, although it wouldn't be a bad idea to pick up some arctic silver 5.
 

http://www.bjorn3d.com/read.php?cID=1916&pageID=9499 <--- That 750w psu will easily push two of those cards in SLI and leave you plenty of juice left over.
 
The 750 watter is more than enough for twin 460's or 560's .... (a 570 would push you up into an 850) .... an EA series would generally get a 9 outta 10 rating which, will provide plenty of power and yet I would be concerned if looking for the most extreme overclocks with regard to voltage stability at peak loads. It might cost you that final 0.1 or 0.2 Ghz on your OC but if you were chasing that, you'd be using a more expensive motherboard and a better CPU cooler.

With what you got, I'd expect an easy 4.5 4.6 Ghz

As to AS5, here's why I say "no":

http://www.arcticsilver.com/as5.htm

Due to the unique shape and sizes of the particles in Arctic Silver 5's conductive matrix, it will take a up to 200 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink or with a low speed fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will often drop 2C to 5C over this "break-in" period. This break-in will occur during the normal use of the computer as long as the computer is turned off from time to time and the interface is allowed to cool to room temperature. Once the break-in is complete, the computer can be left on if desired.

So by my estimation of this statement it would take almost a year of normal use to properly cure the AC5 compound, or almost nine days of continuous power cycles to meet their recommendation.

Shin Etsu provides the same performance w/o the curing hassle.
