New build pushes PSU...

[Crucible1001]

Ignore everything below, I decided on a minor upgrade

I am looking to do a major upgrade, but a new PSU makes it too expensive.

I used the extreme power supply calc and it came up to 750 as recommended, 700 min. Well, I have a high quality 750. I made sure not to miss a single component. I even left room for overclocking the cpu and video cards.

2x AMD 6950 @ 6970 bios (I could leave it at 6950 for now if needed because of issues with the flash that I have heard about)
1x Sandy bridge 2500k @ 3.8
3x 7200rpm hard drives
1x ssd
2x DDR3 sticks
2x 120mm fans
1x 140mm fan
1x DVDRW
3x usb devices
1x MSI P67-GD65

All powered by a corsair 750TX. I would have to go absolute max load on every single device in order to hit 750. That will never happen. Even stress testing gpu/cpu.

I am ready to order the additional parts now through newegg and overnight them here.

You'll be fine. You won't be maxing that out very often at all.

Even if you do max it...the Corsair is a quality PSU and can actually handle sustained maxed loads very well. Worse comes to worst, you still probably have a warranty on your PSU.

That is true...

I can have this build in tomorrow morning, or get a x38/x48 board in a week with a second video card.

Would I notice a huge difference going to the 2500k and ddr3?

2500K is a pretty substantial leap from a Core 2 Quad...especially when overclocked.
