Thermaltake Toughpower SFX 550W

There will undoubtedly always be a high demand for PC components specifically designed for small form factor systems. Put simply, there aren’t that many around, comparatively speaking, and with such a limited market, it can sometimes be more than a little tricky to find the right parts to meet the requirements of your intended build. With the release of the Thermaltake Toughpower SFX series, however, if you are in need of a small but exceptionally potent PSU, then this might be perfect for you.

Coming as a fully modular design, this means that you only need to install the cables that your build requires. And fewer cables means less clutter, better airflow and, overall, better management. Given that this is an SFX design, you clearly don’t get as many options as you might see from within a larger ‘standard’ design. That being said, however, for small form factor systems, this should still provide you with plenty to ensure you can easily hook up all of your components!
