I'm trying to save money, so I'm not sure which PSU to get. Currently I have the M12II on there, but I'm also looking at the OCZ ModXStream Pro 600W. Another choice is the COOLER MASTER Silent Pro M600. So, it is "worth" to downgrade to these PSU's to save some money, and if so, then which one is a better choice? If you have any other suggestions for a modular power supply please include them.
The ModXstream has 2A more on the 12V rail, but 2 years less warranty, is lesser quality, and isn't 80+ Bronze. I think the higher quality and extra warranty are worth it, but you make the final vote with your money.
