Any quality 450w power supply will be fine for your system. Coolermaster while they have great cases and CPU coolers are not a company I trust with power supplies. They do have a few specific models that are good but the Extreme Power series is known to be basically crap.
Stick with Corsair, Seasonic, PC Power and Cooling, XFX, Silverstone, Enermax, OCZ and Antec for quality.
thanks for the suggestion, im looking for low budget PSU at my place/country, but most of the PSU they sell are pretty expensive for me to buy for this moment. im looking for low budget around 70$
