Returning readers have most likely seen a wide selection of SFX power supplies coming through the LanOC office over the years. I have to admit, I have a little bit of an obsession with these tiny power supplies. It’s because I love building small form factor LAN rigs and you can’t go small without having the power to push it, so when I first saw Silverstone introducing them a few years ago I jumped on them and used them in Lunchbox 2. I later built our entire Lunchbox 3 all around one as well. Recently a few other manufacturers have been jumping into the SFX market. This is exciting for two reasons. For one it means more options. But the most exciting thing is that most of the companies who have been bringing them out also manufacture cases, meaning there may be more SFX based case options coming in the future. Well, Thermaltake introduced a 450 watt and a 600 watt recently and today I’m going to check out the 450 watt and see what it is all about and find out how it compares to the Silverstone and Corsair SFX options.

LanOC Reviews only covers the features of power supplies due to not having the equipment to test them up to our standards. Because of this, you will not see a performance section, a final verdict, or awards. Therefore, we prefer to call this a preview rather than a review. Thank you for understanding; we keep our standard to the absolute highest for you, our reader.

If you like the small form factor builds, you should be excited that Thermaltake now has an SFX power supply available. Not only for the variety, but for what it could mean with future case options as well.
