Will my current PSU in my rig be good enough for a 7970?

[Overmind12812]

Hey everyone! I'm just about ready to pull the trigger on a 7970 on Newegg and I understand a 650W PSU should be good enough to power it. But, I'm not sure if it'll be enough given how my rig is currently setup. Here's the specs:

Asus P7P55D E-Pro Mobo
Core i7 860 OC'd to 3.6 Ghz (running 24/7)
1 Intel 40 Gb SSD
3 1TB WD Caviar Black HDs
HAF 922 Case with 3 case fans
Corsair 650 Watt PSU
Nvidia GTX 460 (to be swapped out with the 7970)
8 Gbs Gskill Ripjaws (4x2 gb)
Cooler Master Hyper 212 + with two fans (push/pull)

My question is will the 650 watt PSU be enough to power the 7970 with all these components as well as the OC for the CPU? This rig was built a couple years back and has served me well and I don't see any need to spend the money on a new build at the moment, at least considering what I'm doing with it (gaming/video editing/encoding/etc..). But, I've been thirsting for a triple monitor eyefinity setup for gaming and editing and would really like to only have to invest in the 7970 and will think about building a new rig next year.

Thanks so much for any and all input; I've got a lot of respect for the good folks here at Tomshardware (you guys originally helped my with this build which was my first! .

You'll be fine with a single 7970.

i use http://support.asus.com/powersupply.aspx as a ballpark guess-a-meter for when i need to figure out wattage for my builds.

All good , the 7970 power consumption isnt too high, enjoy!

Enjoy, it's going to be fine, TX650 is a very good PSU. As long as you don't crossfire.

If you're buying a 7970 I think you can shell out for the AX corsair series. (modular)

I'm using an AX850 for mine, but a 650 would be fine as well.

I went ahead and bought my 7970 and my 650TX holds up just fine even with my i7 860 Oc'd to 3.6. Other than being modular and 80plus gold certified I don't see any benefits to the AX series over the TX series.
