Be quiet! Reveals SFX Power 2 and TFX Power 2 PSUs

be quiet! has announced two new power supplies, in two different form factors – the SFX Power 2 as well as the TFX Power 2.

The SFX Power 2 is an SFX form factor power supply that is capable of delivering up to 400 W of juice. It is 80-Plus Bronze certified, and has sleeved cables between 35 and 50 cm long.

The TFX Power 2 is a TFX (Thin Form Factor) power supply. This model may only be rated to deliver up to 300 watts of power, but it is 80-Plus Gold certified. Cables are up to 65 cm in length.

Both of the power supplies are built using a dual 12 volt rail design, and they come with all the safety features we've come to expect, including OCP, OVP, UVP, and OPP.

The SFX Power 2 300 W will cost €55, while the 400 W unit will set you back €67. The TFX Power 2 80-Plus Bronze will cost €55, and the 80-Plus Gold version will set you back €67. No word on U.S. pricing yet.

    I used an older BeQuiet SFX PSU in an HTPC I built for a friend recently,
    works very well. The system runs virtually silent. I'll look out for these
    newer models as I want to build a similar system for myself. Thanks for
    the report! Just hope they're not marked up too much by the time they
    reach the UK.

    It's great to see updated SFX PSUs, especially with all the console-sized PCs on the horizon thanks to steam machines. There's a Lian Li case I was interested in building a modest console around that takes SFX PSUs, so having another option is never a bad thing!

    Dang. I was super excited by this post and then found out that they're 400w and 300w.Still waiting on silverstone's promised 500-550w PSU. (Heck, even if they would release a beta one that was slightly larger than the SFX form factor...)

    Darn. was super excited, until I read the wattage rating. 400w bronze isnt bad, but it comes in at $91. silverstone's sfx psu is 450w, gold rated instead of bronze, has modular cables, has "thin" cables avaliable for tiny builds without a lot of space, and is only $3 more expensive.
