The 650 is plenty, I'm willing to bet.

Last few weeks I have wondered if my Corsair TX650W is not enough high quality power.

So today I picked up a Corsair VX450W that I have wired up to only power the 2 HD4770s. The rest of my system is being powered by the Corsair TX650. Over the next couple of days I'm going to be testing this set up to see if I may have a PSU weakness.

So I have a high quality multi-PSU 1000W system now.

I'll be running some test with this set up to see if power is my problem

Man u are in my head?
I was wondering about this too!!!
If my TT 600 is enough for all this when cpu @1,5volt+...
When i did a test with only one card in i kind of though that he system was SO much more stable and cool that with crossfire!
So i d be waiting for your results pal!

PS:Maybe i do the same and hook up a 400watt on all my fan,cathodes and staff...
Its no name but i think it will handle the fans and the disks too dont u think?
Leave the main for mobo and vga s only...

Have u increased the cpu volts?
If not give it a try say 0,05 volts for start!
And check again if u can have 3ghz stable!

oh ive done that had it on the highest volts my mobo will do still no luck, ive messed with my timings too still no luck

If my system comes in at 588w@3.6GHz 1.38v
yours is definitely fine on 650w especially with that brand PSU

Dont put much faith in the online voltage calculators, In real life they arent very close.

Get a "Kill a watt" instead

They are great :toast:

I'm pushing for 4.5 GHZ with my system. Getting closer to 4.5 GHZ all the time. :toast:

Movie of HD4770s performing in Xfire in my RIG with Q9550 E0 overclocked.

Turns out the Corsair TX650 is enough power to push my RIG to 4.3GHZ.

Ran OCCT Power GPU/CPU linpak PSU test with the Corsair VX450 wired to the HD4770s and the Corsair TX650 and there was just a little less ripple but nothing worth buying a new PSU. Corsair TX650W seems plenty enough power for my RIG.
