Im planning on purchasing the antec p180 black since theres a black friday sale on it, and im wondering if its ok to just transfer the PSU that came with the case im using right now, its a raidmax scorpio 420W 12V power. I dont overclock or anything either. i have a a64 3000+ and pny 6600 256mb agp and some pny ram. Question is basically should i just stick with the psu i have now or just purchase another one?
