There is no doubt that the OEM change dramatically improved the new Cooler Master GX PSUs. Also they new models retain the same price, along with the same warranty period. However I can't say that I am fully satisfied with the GX650W Bronze performance. The unit uses outdated technology (passive design along with group regulation) so its performance is only above average. To be more specific, I would like to see tighter voltage regulation, especially on the minor rails and much better performance during Crossload tests. Also it is crystal clear that +12V cannot deliver the claimed 624W without dropping outside the ATX voltage regulation limits. Nevertheless, the PSU managed to deliver its full load even with 50°C operating temperature, efficiency levels were quite good and ripple/noise suppression was greatly improved compared to older GX PSUs.

Bottom line, if you can live with only three peripheral connectors, won't run a real life load similar to the CL2 test and if the asking price is around $60-65, then the GX650W Bronze could be a decent choice for a mid range system. The included five year warranty will give you piece of mind for a long time.
