well yesterday i bought an HD6870 in replace of an HD7750 and it will arrive in 3 days, but from what i know this card uses 2 6pin pci e connectors, my current power supply has them this one is https://www.pcfactory.cl/producto/8573-Fuente.Poder.650w..12cm

i dont know if it will cause any problems so i want to know if this other power supply is ok for my new graphics card https://www.pcfactory.cl/producto/12728-Fuente.Poder.450w..12cm.Builder.Series.VS450 im in a tight budget so thats why i cant a afford a better one

My current system is
Fx6100 3.3ghz
ASUS M5a78l-mlx3
HD xfx 7750 core edition
1x8GB corsair vengeance ram
500GB western digital HDD main
160GB western digital HDD secondary
spektra 650 power supply
2x thermaltake led fans
