It would be fair to say that I was pleasantly surprised by the overall quality and performance of the BitFenix Whisper M Series 850W power supply. I don't mean that to sound like an attack on Bitfenix, but I have never been a big fan of their power supplies – they have exhibited some issues I was never willing to accept. It was a clever move from them to use the high performance, reasonably priced CWT platform.
Technically the BitFenix Whisper M Series 850W scores well. Ripple suppression is stellar, load regulation is tight and the supply offers a full gamut of protection systems.
The only real downside to this power supply is the somewhat noisy fan when the unit is tasked with higher load demands. Its not horribly intrusive, but if you are sensitive to fan noise and are running a demanding system likely to require more than 600 watts under load then we recommend you look elsewhere. This is not a semi passive design either, but fan noise at lower loads is perfectly acceptable and not annoying at all.
The Whisper Series from Bitfenix is clearly a move in the right direction for the company. If you are building a new gaming system and have around £100 to spend then this BitFenix Whisper M 850W model deserves some serious attention.
