Adding GPU, is current PSU enough?

[Gronnie]

Current rig:

Corsair 500R
ASRock Z87 Extreme4
Intel i7 4770k
Zalman CNPS9900ALED Cooler
Samsung 840 EVO 250GB SSD
16 GB DDR3 1600 Ram
Three 1TB WD Caviar Green HDD
HIS IceQ 7950
Four LG UH12NS30 BD drives
XFX P1-650X-XXB9 650W 80 PLUS BRONZE Certified Modular Active PFC Power Supply
Dell U3011 and 2x Dell 2007FP PLP, Samsung 220WM mounted above ( and planning on adding two more 22" 1680x1050 eventually)
Windows 7 Ultimate x64

 

Just picked up a HIS IceQ X² 7970 3GB on a really good deal, card is almost brand new. Planning on adding it to current rig (meaning will have both 7970 and 7950 installed), but not sure if PSU is big enough?

 

I also have a Corsair HX750 in another rig that I repurposed to be a server that I could swap with, but don't want to spend the time and work if not neccessary.

The psu is much more than enough.

Wow, I figured a 4770K, 7970, and 7950 at the same time would draw a ton of power. Good news I guess.

Yeah, I wouldn't call it way more than enough.  But its enough, you can add some more drives, overclock your cpu and that kind of stuff, put it that way.  But you cant add another 7970, thats too much.

Just to be clear, when you say ANOTHER 7970 you mean in addition to the one I already plan on adding, right?

Oh, hold up--my bad. I misread the post. 

You'd probably want a decent 750w+ for a system with both a 7950 and 7970.  I originally thought you were just adding a 7970 to a system without a graphics card.

yes, although.  I mean if you remove your current graphics card and replace it with the 7970, then yes.  If your adding the 7970 to your current setup, then no, you will need a bit bigger I recommend 800watt to be safe or a 750watt 80+ gold.

yupe,you should be fine with that psu. Btw, are those 'four' BD drives or just 4x speed?

It is 'four' BD drives. I use this rig to rip lots of BD, compress them a bit with Handbrake, and then transfer them to my server.

atleast 700-800w when you crossfire top end amd cards.
