SilverStone Releases SX700-LPT, SFX-L At Platinum Efficiency
ilverStone released a new addition to its SFX line today: the Platinum efficiency SX700-LPT which follows the SFX-L form factor.
The major disadvantage all SFX PSUs suffer is that their size limits fans to 80mm (or 92mm in ideal cases). This leads to increased output noise, especially under tough operating conditions, since such small fans have to spin at very high speeds in order to offer adequate airflow. In an effort to solve this problem SilverStone tweaked the SFX form factor and introduced the SFX-L, which has the same width and height as SFX, but specifies increased depth to allow for a larger cooling fan (up to 120mm in diameter). While the dimensions of a common SFX unit are 125mm (W) x 63.5mm (H) x 100mm (D), an SFX-L unit's dimensions are 125mm (W) x 63.5mm (H) x 130mm (D).
So far the only SilverStone PSU compatible with the SFX-L form factor was the SX500-LG, which we have already reviewed. But this changed today with the official release of the SX700-LPT. We should mention that SilverStone also revealed during Computex last week its high-end SX800-LTI, featuring Titanium efficiency, but there is no information yet on this product's release date.

The PSU features a fully modular cabling design, including four PCIe connectors and a single EPS connector. Ideally it should be equipped with a pair of EPS connectors because it has enough capacity to support them. The MSRP that SilverStone told us is quite high, however in PSUs (and other PC parts) usually the smaller the size, the higher the price. What we find unacceptable at this price point, however, is the limited warranty, especially because the competition (Corsair's SF line) backs its offerings with a seven-year warranty period.

There is a single +12V rail which can deliver more than 58 Amps. The minor rails are pretty strong as well, while the 5VSB rail is a little stronger than we typically see.
