Glad you are all set. And I already bought myself a 900. Next case I get will likely be the Mini-P180.

Antec’s TruePower Quattro power supplies, the TPQ-850 and TPQ-1000 have more than enough power to run an 8800 graphics card and are SLI certified by NVIDIA. The actual issue with the graphics card and System Sentinel is a communication issue. The Supply has plenty of power, but the card is not handling it properly.
This problem is not only with the Antec supply. Other brands of power supply are having these issues as well. There have been reports of power supplies from Corsair, ThermalTake, Enermax, Rosewill, OCZ, XCLIO, and Silverstone not working with these cards as well.
Nvidia SLI certified our power supply to work with the cards. Months after the launch of their card we started to have problems with the 8800GTX and the Quattro supplies. We implemented a fix at this time because we were the only company with the issue. This fix worked for any user having the 8800GTX issue.
Then Nvidia released the (G92) core series of graphics cards GTS/GT. These cards do not work with either the original or fixed version of our power supply. We have been researching the issue, and Nvidia has been testing this issue in their labs. The problem appears to be a hardware interaction. With the right (wrong?) motherboard/graphics card/PSU, this issue occurs. It seems that a bios fix/flash is going to be the easiest way for this issue to be resolved. I suggest contacting Nvidia to see if they have a fix at this time.
, well I mean when you wrote it lol.
