Does my PSU have enough oomph?

Hokay, so I'm curious as to whether or not my PSU will be able to provide enough power to my system, as I'm going to be making a couple of additions to it.

PSU: Zalman HP-850
System: i7 920 OC'd to 3.8Ghz (1.27V)
P6T Deluxe V1, 12Gb DDR3 1333 (3x2 DIMMS)
2x9800GX2
Two (soon to be five) 7200 RPM HDDs of various size, along with one SSD.
XONAR Essence stx sound card powered by molex.
6 S-flex SFF21G case fans.
Two Optical Drives, one is a burner, the other is just a DVD-ROM.

The main reason I ask is because I have this system folding across the CPU and all GPUs almost all the time. What would happen should I overload the PSU? Should I think about getting a bigger one? If so, what would you recommend?

...it might be worth noting that occasionally upon starting up my virtual machines for folding my computer does freeze/hard lock.
 
Why 5 HDD drives?

I haven't been able to figure out about Zalman PSU quality, but they are rebrands...

Unplug the other DVD drive to remove 25W at inrush.

The maximum the 9800gx2 can take is about 200W, IIRC. So... it can work, but you'll be pushing your PSU's lower limits.

Wait for/PM Danny Bui for better info on this.
 
The ZM-850HP is built by Enhance. It's a good PSU. You'll be getting a bit close to the limit, but it still has plenty of power for your system.
