I am just wondering if the Bitfenix Whisper 650W power supply is a good one? JohnyGuru's review was I believe a 8.9 which I think is pretty good. It is not all that pricey so that is why I am considering it as a Power Supply upgrade.
It is always best to go by professional reviews, like the one you referred to. The Bitfenix Whisper M series power supplies are actually very good quality and electrical performing, comparable to the highly rated and popular EVGA G2 and Corsair RMx.
