Recommend a new PSU since I think I may not have one that is big enough.

What is the best power supply for this build? I have all but the RAM, Intel 750 PCIE SSD, processor, and motherboard already.

I am not sure that my current PSU (it is in the list) will quite hold up, but maybe I am wrong. I generally have all my USB ports filled (currently 8). I have the parts I don't have yet on order since the rest of it is on a system with an MSI 870-g45, AMD Phenom II x6 1045t, and 16gb DDR3.

Here is what the build will look like after I get the parts in, and again I have most of them already: http://pcpartpicker.com/p/xDrtTW

Your previous PSU was questionable to begin with and I would never trust $3000 worth of equipment to pretty much any Corsair PSU.

There's a killer deal on an 850W XFX PRO atm, especially if you don't mind rebates. That said, this build strikes me as the modular PSU type of build. Look at XFX, Seasonic or EVGA.

Corsair is popular choice and not bad in all cases. Some Corsair psu are build from Seasonic if I am not mistaken. And Seasonic and Super Flower are making the best psu.

I did not calculated how much power your rig will need. But I would only trust the best. It costs a little. Look for Super Flower or Seasonic brands and Gold rated units have higher quality build. Thats the case because to get better efficiency, the build needs to be of higher quality parts and build. Your components of pc will last longer than compared to cheap psu and there is less potential of risk. If you have money, then even go for Platinum rated units.

Definitely looking at a modular PSU for it, and one that will be nice, stable, and wont fry my equipment. I will likely move the current MOBO/procesor/RAM combo to another case, slap one of my spare 120gb SSDs and the old 1tb and 2tb HDDs I have in with it, the GeForce 650ti Boost graphics card, and the 750 watt Corsair PSU currently in there. I was pretty sure I was on the edge of what the PSU can support anyway.

So, think 850 watts would give me enough headroom? Should I go ahead and get a 1000 watt PSU instead? Also, looks like there are many versions of the XFX 850 watt PSU on Amazon, but I did go with narrowing it to XFX, EVGA, and Seasonic. I did not see Super Flower. I limited things to 4+ stars too.

Stay away from the CX series from Corsair, especially on high-end builds.

Also, give yourself more headroom with the PSU. In this case I'd go for 1K at the minimum. (It also puts the PSU back into it's higher efficiency band.)

EVGA SuperNOVA 1000 P2 1000W - (1000W, High efficiency, good build quality, and piece of mind - What's not to love?)

Ok, Super Flower seems not to be available with prices at partpicker. I read a lot in the internet before buying my Super Flower unit and it is amazing. (Sounds like advertising.^^) PartPicker calculated a need for 706 W. Add 20 % to it for peak times, overclocking and later for an aging psu. 850 W should be fine with headroom. Here an example:

and some reviews about that unit

That EVGA 1300G2 seems to be very good. It gets excellent ratings everywhere I look. And then I read this:

"Like its smaller brother, the G2-1000, this PSU is also made by Super Flower. It is based on a Gold version of the normally Platinum Leadex platform."
> http://www.techpowerup.com/reviews/EVGA/SuperNOVA_G2_1300/4.html

I have no doubt on the quality of this product, but the fans are a little loud to my taste.

If you don't care for a silent system, then this psu is a good choice. It does not matter that it is a little over powered. You probably never will need it.
