So over the past few years and especially in the past few months I’ve had the chance to take a look at a variety of SFX form factor power supplies from a few different manufacturers. So far all of them have fit the standard SFX form factor, but recently Silverstone introduced a few power supplies that are SFX-L. The SFX-L form factor is the same size as other SFX power supplies in most dimensions, but they are slightly longer. This extra length squares off the SFX form factor and allows for a much larger fan to fit inside. The extra space and cooling also allowed Silverstone to up the power a little up to 700 watts. This is exciting because it finally allows for proper SLI and Crossfire setups in the SFX form factor. So today I’m going to take a look at the SX700-LPT and see what is different than Silverstone’s other SFX power supplies.

LanOC Reviews only covers the features of power supplies due to not having the equipment to test them up to our standards. Because of this, you will not see a performance section, a final verdict, or awards. Therefore, we prefer to call this a preview rather than a review. Thank you for understanding; we keep our standard to the absolute highest for you, our reader.
