During Computex 2015, Corsair's representatives informed us that they were planning to include the SFX form factor unit that powers the Bulldog (opens in new tab) system into Corsair's portfolio of PSU products. However, this hasn't happened yet, since the release of the Bulldog was delayed. According to the latest info that we gathered, the Bulldog will probably be released into the U.S. and UK markets during the first quarter of this year, equipped with different mainboards (according to region).
In addition to the SF600, Corsair showed us a smaller capacity PSU with the model number SF450. Obviously they thought that it would be better to enter the SFX market with more than one offering, thereby covering more ground. The SF600 looks ideal for small but powerful gaming systems with up to two GPUs, and the smaller member of this line is destined for single GPU systems. Given that an Nvidia GTX980 doesn't consume more than 200 W of power at stock speeds, even the SF450 is enough to cover the needs of a strong gaming station.
The two Corsair SFX PSUs will probably appear on store shelves in February of this year, and the asking prices will be $90 for the SF450 and $120 for the SF600. Both PSUs are made by Great Wall and feature a fully modular cabling design, a semi-passive operation and will be backed up by a seven year warranty period. In addition, according to Jon Gerow (most of you will know him as Jonnyguru), who recently was appointed as Corsair's new PSU product manager, only Japanese capacitors will be used in these units for increased reliability and prolonged lifetime. We expect the first review samples to be shipped pretty soon (if they haven't been shipped yet), so stay tuned for detailed information on their performance.
