Everyone loves small form factor PCs these days, but there aren't many SFX power supply options that can keep up with the demands of increasingly powerful CPUs and GPUs. A number of companies have been able to hit 600 watts, and SilverStone was able to reach 800 watts, but only via its "SFX-L" form factor, which is slightly larger than the official SFX specification and therefore doesn't fit in all situations or case configurations.
But SilverStone is back with the first true SFX PSU that hits 700 watts. The SilverStone SX700-G is an 80 PLUS Gold-rated power supply with a fully modular design, single +12V rail, and a 92mm fluid dynamic bearing (FDB) fan tuned for silent operation at low loads.
The SX700-G includes SilverStone's flat cable design for easier cable routing and enough power cables to connect up to two GPUs and six SATA drives. It is launching with an MSRP of US$155.99 and should reach retailers in North America by mid-December. Check out the complete list of specifications below.
