I was surprised to see how low the power usage was for the build so I ended up switching it out with a Corsair CX450M PS and am now using the RM750i on my test bench. Still liking the digital link.
This power supply is silent; The fan doesn't kick in until your build is pulling over 300 watts Corsair Link Digital monitors performance, temps, fans speed; Very cool Very stable power as per posted reviews
Price if not purchased on sale; I got it on sale with a $20 rebate; (Still waiting for that rebate though after 2 months
