Hello everyone. My question is will any of these cards I list work with this setups PSU? I always built systems with more than needed/quality PSU's, but this setup is all I have at the moment and wondering if my PSU can run efficiently with any of these cards. I am not going to overclock. The PSU calculator on Thermaltake's website says they will, but I have my doubts. Thanks for the help!

AMD AM3 Phenom II X2 545 3.0MHz Callisto 80W
GIGABYTE GA-MA785GM-US2H 785G Micro ATX Mobo
LG IDE DVD/RW Drive
Patriot Viper DDR2 1066 4GB (2x2GB) Ram
1x WD 320GB SATA 3.0/GBs Hard Drive
2x 120mm non LED Fans
1x 200mm non LED Fan
Corsair HX450W PSU

Cards I am considering. These are the choices I have as friends that upgraded have these for sale. They are all stock clocked.
