Given its small size, having four PCIe connectors, six SATA connectors, and three Molex connectors on the Seasonic FOCUS SGX is no mean feat. That will give almost any SFF build more than enough power, or even a full sized build if you prefer a small PSU for whatever reason. The 10 year warranty indicates Seasonic has a lot of faith in this unit, and [H]ard|OCP's testing shows it is deserved. You will pay a little more for the FOCUS SGX but in this case it is actually worth it.
"Seasonic is FOCUSing more on small footprint high output power supplies, and the new FOCUS SGX series is targeting the small form factor market once again. This beefy 650 watt unit is fully modular, packs a 10 year warranty, is diminutive in size, had good efficiency, and comes complete with an ATX adapter plate as well."

Introduction and Features
Seasonic continues to be one of the most respected names in the PC power supply industry. In addition to selling power supplies under their own brand, Seasonic is the OEM for numerous other PC power supply vendors. Their new FOCUS SGX Series currently includes two power supplies, the SGX-450 (450W) and the SGX-650 (650W), which are designed for use in small form-factor builds. We will be taking a detailed look at the SGX-650 in this review.
Both FOCUS SGX power supplies are fully modular and comply with the 80 Plus Gold certification criteria for high efficiency. The SGX-450 and SGX-650 use a 120mm fan with a Fluid Dynamic Bearing (FDB) for quiet, reliable operation and can operate in silent fanless mode (below 30% load) thanks to Seasonic’s Hybrid Silent Fan Control. The compact SFX-L size chassis measures 125mm square and both power supplies are backed by a 10-year Seasonic warranty.
