SilverStone is constantly pushing the power density scores of its SFX products higher, and the new SX800-LTI unit, which we first saw at Computex this year, is clear proof. This unit is the flagship of SilverStone's SFX-L models, and with 800W capacity, it's able to deliver up to 66 Amps on its single +12V rail.

Despite its high power, it still uses a semi-passive mode that deactivates the fan under light loads, in order to offer a dead silent operation. The rest of this unit's features include an 80 PLUS Titanium certification and a fully modular cable design. Moreover, SilverStone used only Japanese capacitors for increased reliability.

It is a great shame that the SX800 doesn't have a couple of EPS connectors, to support high-end mainboards that need more juice to the CPU. With four PCIe connectors, though, it can support up to two strong VGAs, so it will be ideal for a potent gaming station. The number of SATA connectors is also impressive, given the PSU's compact form factor. We would also like to see a five year warranty, at least.

SilverStone hasn't yet revealed pricing, which is a crucial piece of information. Further, for the moment, this model doesn't look to be available in any online store we searched.
