I lost my tooth and power unit for the computer

I lost my tooth today and now I'm feeling weird.

My options for power supply on the computer were narrowed down to two based on what a gaming company uses in their computers and what the reviewers said about amount of power needed.  Minimum was 750 watts of power, and I would need to replace the fan with my cool one as fans are part of the power supply I found out.

The first option is the:

Quattro by Antec, it is 850 watts or 1,000 watts

Cost:  between $200 - $300

The second option is the:

Corsair CMPSU 750 watt power source

Cost: $200

My selection is the Quattro by Antec
