i used the power supply that came with my case which was a 350w aspire psu pos it wouldnt even boot MY system (see sig) so i went out and bought a cheap 350w antec truepower and it runs great b4 would not be able to get into windows just constant nonstop restarts so in my opinion get a good power supply and be done with it,
that last post was uncalled for and foul language is not tolerated on this forum as is flamming to. DiabloII probly knows a lot more about computers than you do.
I myself was on an even tighter budget on my computer. I spend $450 for it and managed to get a reasonably good power supply whereas for 650 i would def get a good power supply
Found this in a review on Newegg
heres the link if you dont believe me
-Great case, LED lights look great,lots of room but the only flaw is that the power supply didnt hold up it died on me a week after i bought the case. Still recommend the case whos looking to build a new comp.
