BitFenix today introduced the Whisper M line of premium modular power supplies (PSUs). Available in capacities of 850W, 750W, 650W, 550W, and 450W, these PSUs feature a design focus on low fan noise, with the 135 mm fan spinning at less than 500 rpm at loads of up to 70%. The units feature fully modular cabling; with the 850W and 750W models featuring six PCIe power connectors, 650W model featuring four, and 550W and 450W featuring two. The 850W and 750W further feature two 4+4 pin EPS connectors, making them ideal for dual-socket workstations.

Under the hood, the Whisper M features a multi +12V rail design with 80 Plus Gold switching efficiency, DC-to-DC switching, active PFC, ripple and noise reduction circuits, most common electrical protections (over/under voltage, overload, overcurrent, AC input surge, thermal-trip, and short-circuit protection), and ATX 12V v2.4 compliance for the latest generation processors. The Whisper M Series come with 7-year warranties. The company didn't reveal pricing.

From those images, these are not single rail.
650, 750, 850 quad rails and 550 triple.
Well, they have to be, if they're to participate on the German market successfully. Which is also why they're big on being quiet and having long cables :)

Based on CWT GPU platform, which seems to be an evolution of the CWT GPS (Thermaltake Smart DPS G Gold, Enermax Revolution X't II, Deepcool DQ-M, ...), so should be at least decent.

650,750 & 850 have dedicated quad rails, 450 n 550 have three rails, but unlike other PSUs, this ones have higher wattage for gpu rails, and also the components are really good ones as I've heard. also it is like 18db quiet...

Article does mention it was multi +12V rail not single rail.

Actually, multirail PSU's are a lot safer than single rail. When shit goes wrong on single rail, individual failed component can pump the entire wattage and amps from the PSU through that component, melting it into pure lava. Where with multirail, it'll trip the OCP protection on individual rail of the failed component a lot faster, preventing catastrophic meltdown.

I never thought of that until I listened to Corsair's PSU engineer who explained this.
