PSU upgrade question

I recently acquired an Evga Supernova 750G2 for a good price for an upgrade to my HTPC. After I got it, I noticed it was almost as large of a unit as my old 1200 Watt PSU and would not fit the HTPC . I am now wondering if it would be a decent replacement for an almost 3.5yr old Coolermaster Silent Pro 1000Watt PSU in my main rig or am I cutting it close power wise?

I do plan on running a Nvidia 970 or 980 plus a 650ti or so in the near future. I fold and run WCG on all of my rigs, so that is why I was going for that additional mid grade GPU in addition to the 970or 980

The 970 or 980 is the only thing I will be changing in the near term, so I was wondering if the following would be ok when I got the new card?

Intel 3770 K @ 4.20
Gigabyte Z77-UD5H
about 7 or 8 fans total( mainly noctua's and Gentle Typhoons)
GTX 970 or 980 and a 650ti ( currently using 2 660ti's)
3 HDD's , 1SSD, Blue Ray burner, sound card
a custom jerry rigged 4 way light switch to LEDs across the room (roughly 25W on 12V rail if all lights are on)

Would I be better off replacing that 3 year old Coolermaster with the new 750W Evga or would the 750 be cutting it too close to the limit ? I currently pull roughly 475Watts max from my UPS readout while folding on both of my current two 660ti's and crunching with 75% of the CPU . Thanks in advance and my bad on any and all grammar errors. I had a few to drink.

Edit: I should mention this is a 24/7 rig.

how is it pushing anything if a 970/980 is not even 100 watts more than a 660ti?

are you saying you want to replace a perfectly fine coolermaster? well what would happen to it now?

Short answer, yes.

You're going to be consuming less than 750W, and the G2 is one of the best PSU's money can buy.

980/970 = 210W (Furmark) as both GPU's consume the same power
3770K = 100W
650ti = 120W
All that plus an extra 100W overhead for motherboard and other gubbins. It equates to ~550W

Thanks. I should be ok even if I got 2 770's from the sound of it then.

I'd probably sell it or maybe use it for another build.
