since i passed my A+ Certification recently, ive decided to build or maybe i should say upgrade to a better pc. im using some of my parts from my current rig, which include a sony dvd+/-rw, samsung cd-r, maxtor 200gb hdd, and a WD 40gb caviar hdd. I went to newegg.comto buy my new case, mobo, cpu, psu, and ram because of their great prices and service. now im in a predicament, im purchasing a Raidmax case that has a 420w psu bundled with it (URL) and a Rosewill 500w PSU (URL). Now, the question is, should i forget about the Rosewill and just stick to the bundled PSU or should i buy the Rosewill and have the bundled one as a back up? Thanks in advance!
