There should be no problem with power. We are running tons of Delta66's 
and I used to have a few 1010's as well. Easy cards to work with (so I'm 
surprised at the problems you are having). The 1010's had problems with 
some capacitors in the break-out box (in the power supply doubler or 
quadrupler circuit) - replacing them fixed the issue.
