So I have my 4-module hashing happily at ~75Gh/s with the stock 750w psu and using the max clock settings in cgminer for my power. The Avalon Wiki says that I should bet getting :

Hashrate：90GH/s, Chip:282MHz, 750W

What am I doing wrong?

Check the WEB page under the system ---> "cgminer API log"

You should find lines that say

[match_work_count]

from 1 to 32. These should all have similar numbers.
If you have fewer than 32 workers, go to the configuration tab and change the number. Typically, there are 8 workers for each module in the Avalon (8, 16, 24, 32).

If there are 32, but one of the numbers is very low, you have a under-performing chip.

I agree with the recommendation of the OCZ 1250 power supply. My power draw dropped by about 30W after I changed to the power supply as measured by a kill-a-watt meter. I also think the unit is more stable, but I don't have data at hand to back that up, it's just gut feel.

You may want to update to the latest c kolivas firmware and use the --avalon-auto option.

FYI, those OCZ PSU's might be a little harder to get since OCZ filed for bankruptcy a couple of months ago.
