Thing is I haven't bought it yet.

So is it a SeaSonic reskin?

Your PSU will probably die if you add another 6970 in there.

As above poster said, your PSU isn't too good. This isn't the same, but they seem cheaply build:
Quote:
For a group regulated power supply the OCZ 700W ModXStream Pro’s load testing results weren't half bad, until it stopped working; twice.

When I opened the package with the OCZ 700W ModXStream Pro and found a test report from PC Power & Cooling certifying this unit at full load I instantly thought I had a winner. Until, of course, I actually gutted the unit and found the very questionable "Rec" capacitors. Unknown origin capacitors with a PC Power & Cooling stamp of approval seem like an odd marriage that I simply do not understand. Good quality capacitors add very little to the BOM so why OCZ/Sirtec has decided to cut corners here is simply beyond me. Now, while I did not actually have a capacitor failure in this unit given the short time period of testing (just 14 hours) it turned out that PC Power & Cooling test report was not worth a whole lot as I had two units fail to pass testing and over time I would be very concerned about this component selection given the prominent history of dodgy capacitors in power supplies and motherboards alike.
Also note that your OCZ doesn't have cables for 2x HD 6970/50 so you'd need a bunch of adapters to even connect it.

Ok, I think I'll actually go with the M12D-750w.

But would the M12 hold up to 1h of gaming per day weekdays and 4-6 hours on weekends? 3 hour blocks max?

Also, a single HD 6950 draws 160 W and 2 would probably draw ~300 W. Overclocked, you might get a draw of 350 W. Then an OC'd i7 and you're pulling 180 W extra. Then add 50 W for mobo, HDD's and fans. 350 + 180 + 50 = 580 W. And that's an absolute maximum draw which your system would rarely see.
I like having more power than I need. Don't ask why, and yes, I'm getting a 1000W for this system.

620W with an OCed system and 2x 6970 is borderline. You will stress the PSU a lot, I'd rather pick a 750W and have peace of mind.

If it doesn't happen to be an 80 plus silver/gold I'll be confused. Better off spending your money on higher quality power and better over-current protection than wattage that you'll never use.

But the SeaSonic is rated 620 W continuous, it's not like it will fail after four days of 620 W. I'd guess it could do 700 W peak, it's not peaking at 620 W.

The NZXT Hales are some of the best PSUs one can get.

I didn't see the Hale90 in his sig, Hence why I didn't google it.

Had no clue that NZXT made good PSU's though, is it actually them or do they just rebadge?

EDIT:

Also, say I went over the limit on my future Seasonic, would it shut off before any damage was done to the components?

NZXT Hale 90 1kW is rebranded Superflower unit (good one), I can't remember which one for the life of me though.

If you go over the limit on a bad PSU (which is usually below what they state it to be) it has a chance to take some of your hardware with it to the grave. A good PSU should just shut off without damaging anything.

Edit: I'm actually not sure if it's a rebrand of they specifically made it for them, either way it's from Superflower.
