The CoolerMaster 460W Extreme Power Plus is the best option. Anyway, this power supply should be sold as a 430 W unit. If you are building an entry-level PC with just one or two hard disk drives and just one video card (the 4850 included), this power supply is a good option until you have the possibility to buy a decent power supply for your PC.
Extreme Power series was not so good.Old models.Low efficiency.No PFC.
Try to get Coolermaster Real Power Series PSU.They are good ones.
