A couple things:PSU calculators drastically over-rate power consumption in an attempt to make sure people purchase power supplies which will definitely handle any load they throw at it. Case-in-point, an overclocked i7 @ 4GHz doesn't come close to 300W power consumption. Were this true, traditional air cooling methods wouldn't be able to dissipate the heat generated by such a device, we'd all have to use water cooling.

TechguyMaxC, in a previous post I made the statement that "an overclocked i7-950 at 4Ghz draws 300 watts!". More precisely, it should have read "an overclocked i7-950 at 4Ghz SYSTEM draws 300 watts!. My sentence could be taken as the i7-950 cpu itself draws 300W and for that I stand corrected. Thanks for keeping things square!! Cheers,sEdit: added this reference:

I figured as much, they don't want to under rate the power draw when people are using their calculator to select a power supply.

I have found this to be true (liabilities etc.). In fact, before my PSU blew I was running my system described in my sig on a PSU rated at 775 Watts! (I believe my particular unit was defective since it should have entered a current protection/shutdown mode and not a catastrophic failure).You should be fine, however

+1 on the PSU. With my 930 clocked at 4.4 and the GTX 470 I am seing peak wattage (measured at the outlet) of 584 watt so I would go with a 750 watt PSU to have a little more margin

Would you mind telling me why ?thanks.Martin

Sure because it's quite a bit cheaper and it does almost the same exact thing. I find that user reviews tell the story most the time.

PSU probably isn't enough for OCing. You want to put OS and FSX on separate HDs, not on the same or in RaID. Considering the other parts, isn't the UD3R a bit on the cheap side for a mobo?

Since the disk drive is a SSD, it shouldn't really matter if the OS is on the same drive as FSX.

Ah, In my country they cost exactly the same....

yeah, I've been slightly optimistic with only 50 Gb. It's enough for the OS I guess but I think I'm going to save up for a 300 Gb V-Raptor for FSX

Now that I moved my FSX backup files to my WD Caviar Blue 320GB drive, I have 25.2GB left on the Kingston 64GB SSD that my OS resides on.
