Core i7 Build

I'm thinking of making a core i7 system that will last me for the years to come. I'm thinking of getting the i7 920 and just ocing it.
Here's a list of parts i'm most likely going to get.

Vigor Monsoon III LT Dual 120mm Fan CPU Cooler Socket 1366 Ready

Though I can't decide on on power supply. Could somewhat give me a rough estimate as to how much power i'm gonna need to power this beast. Also could someone rate my build and help me possibly improve it.
I'm probably going to get another better board but I'm trying to keep this within a budget of 1500$ if anyone could point me in the direction on a good board that's not like over 500$ that would be great.

600w psu is way too small

you want at least a 650-750 -- some 650 are very high end like antec. many 600w are low end

my rules:

1) i use 750 850 and 1000w psu

2) 850 is use for high end dual cards like 260's or oc 4830's or 4870's in pairs or if you might add one == if you might add a second card go 850. if you probably won't go 750

3) i use 1000w for 4870x2 or gx2 or 295 when you might add a second card

i rarely use over 1000w, i do use 1200w on high end water only, i always use a 750w psu even on my $1800 cheapy systems with 1 gpu.

i have never had one failure - no cpu, no psu no system has failed in 5 years

yes stuff breaks - actually almost never since i use high end parts

oops wrong photo

i get the right one

My 650W PSU is more than enough to run my i7 920, 280GTX, 6GB 1333 ram.

You dont need an uber PSU for I7's with single graphics cards.

I'm still not to keen on the motherboard. Could someone recommend me another board or is this motherboard fine for now?

A quick and dirty way to determine the correct PSU wattage for your PC is to sum the total number of amps for each device and multiply by the voltage.

Keep in mind that power supplies have something called "rails" and even though you may have enough wattage you can still under power your PC, because you exceed the supplied amperage on the (most likely) +12v rail. The +12v rail(s) supplies power to components, such as your graphics cards, CPU, HDD's, and water coolers.

The Cool Master Extreme 600W for example has two +12v 18amp rails. This means that most likely the CPU, HDD, and DVD-RW drives are all sharing the same rail. This could make a PC very unstable when under load. Where as the Seasonic 600W equivalent has 4 +12v 18amp rails. Difference in price between the two PSU's is about $50.

Also you want to make sure that the power requirement for your graphics card does not exceed the available amperage per rail. An EVGA 260 requires 36amps, but only a 500 PSU. This means it will need a minimum of 2 PCI-E 6pin connectors which clearly the the Cool Master wouldn't have. Another example would be an EVGA 8600GTS Superclocked which requires 22-24amps on a single rail. Again the Cool Master would not meet the requirements, but in terms of pure wattage it appears it would as it only needs a 450W PSU.

take a look at the recently released 902 as well.

imo either the CM 690 or the 902.

I recently replaced my aging Cooler Master Centurion 5 with an Antec P182 I got off of the Egg for $100 Shipped. The case is nice, roomy, not too roomy tho, and looks professional. I'm not into the bright LED's and 20K blinding case fans, although my case has many fans. It's a great case that is built solidly. It should last you for years if you decide to go with the P180, but I would recommend the P182 instead.
