SilverStone this week is launching two new “compact” power supplies that pack a lot of wattage into a form factor that is shorter than the typical ATX PSU. The Strider Platinum ST1000-PTS and ST1200-PTS are fully modular 80 PLUS Platinum-rated power supplies at 1,000 and 1,200 watts, respectively.

But the key feature of this series is its shorter depth. At 140mm deep, the PTS series is 40mm shorter than the typical 180mm ATX PSU design. While they won’t fit into the official SFX PSU dimensions (125mm deep), they do offer additional options for obtaining higher power output in smaller case designs. Indeed, SilverStone points out that there’s no power supply currently on the market that offers equal wattage at this size.

And while both models of course come with their own cable set in the box, their fully-modular design means that users interested in using one of these units with a smaller case can easily swap out the included cables for a custom length solution or SilverStone’s own shorter cable set.

Unfortunately, you’ll need to pay a price for the lack of space. The ST1000-PTS will have an MSRP of $209.99 (€181.99 in Europe) while the ST1200-PTS will land at $239.99 (€201.99). While we’ll need to wait to see how actual street prices settle down, based on MSRP these new models come in priced 20-25% higher than Platinum-rated competitors at the same wattages.

But if your small PC design is aching for more power and a full-sized ATX option won’t do, you can pick up the new SilverStone ST1000-PTS and ST1200-PTS when they hit North American and European retailers in mid-January.
