I run all this setup on Corsair AX-750 without problems:

AMD Phenom II 955 X4 Black Edition
NOCTUA NH-D14
MSI 890FX-GD70
4x Corsair 2GB 1600Mhz CL9 DDR3
3x Sapphire 5830 Xtreme
1x WD Velociraptor 300GB
2x Samsung F1 750GB 7200RPM
2x Samsung F2 1,5TB 5400RPM
6x 120mm fans

What OS are you running? I assume Windows if it's also a gaming rig. Win 7? 32/64-bit?

Win 7 64bit

I have the MSI FX890-GD70 and I would not recommend to use more than 2 GPUs inside a normally ventilated PC Case. I have 3x5830 and currently am running only two of them.

I'm using the MSI FX890-GD70 too, with 4x5850, no extenders, in a Coolermaster HAF-X. The 3 bottom cards are overclocked to 900/300, the top one only to 820/300 because of cooling problems... But this way, they run at 74°C (top card), 70°C (2 cards in the middle) and 57°C (bottom card) doing about 1.3GHash/sec. All I did was spacing the cards using some plastic parts and installing one optional 120mm-fan inside the case, blowing directly towards the cards. Power usage is about 670W.

Regarding cooling - we have no A/C in the PC room, so ambient temp is around 24-25°C, which might explain the high/er temperatures in my case of my case Cheesy

It is actually a nice challenge getting a decent PC case with enough expansion slots AND HDD space...Plus it cannot be "not nice"
