If you are looking to power a small form factor system and need a fully modular PSU in order to get it into a tightly packed case as well as high efficiency the SilverStone SFX ST45SF-G 450W is a decent choice. It is Fully modular and is an SFX PSU, which as you might remember from Lee's review means that it lacks a -5V rail, not a necessary feature in today's systems. [H]ard|OCP granted an award to this PSU, not because it is the best 450W PSU available, which is not, but because it is the best fully modular SFX PSU they have seen and they realize sacrifices have to be made in a PSU which is barely able to fit an 80mm fan inside. Check out the full review to see if you think this PSU is worth the price premium or if you might just consider a larger PSU for your HTPC.
"Silverstone is one of our favorite computer power supply builders as the company has a tremendous track record when it comes to high quality and quiet power for our desktop systems. Today we look at something a bit different in terms of scale, a PSU pushing 450 watts of power in a package half the size with its sights on the SFF market."

Introduction and Features
SilverStone has a long-standing reputation among PC enthusiasts for providing a full line of high quality enclosures, power supplies, cooling components, and accessories. SilverStone recently updated their original ST45SF small form factor power supply to 80Plus Gold status. The new ST45SF-G is rated for up to 450W and comes with fully modular cables. The SFX form factor is frequently found in Micro ATX Media Center PCs and Home Theater PCs.
SilverStone ST45SF-G 450W PSU
Here is what SilverStone has to say about the ST45SF-G: "After successfully expanding and leading SFF (Small Form Factor) cases and SFX PSU into the DIY market, SilverStone engineers have continued their push for advancement in these categories by releasing a true upgrade-worthy small form factor power supply, the ST45SF-G. Despite being half the size of regular ATX power supply, the ST45SF-G can still produce continuous power output of 450W. Its 80 Plus Gold level efficiency is a great leap from the previous SFX best of 80 Plus Bronze and the full modular cables are also the first of its kind for this form factor. To enable users to easily take advantage of this excellent SFX power supply, an adapter is included to convert the ST45SF-G to mount in any ATX case in addition to ones designed for only SFX. For SFF users and for SilverStone, the ST45SF-G is more than just an upgrade, it is an important milestone for DIY desktop computer users."
