SilverStone Launches PTS Series Compact ATX PSUs at up to 1200W

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.

SilverStone Reaches 700W in the SFX PSU Form Factor with the SX700-G

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.

silverstone-sx700-g-1.jpg

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.

silverstone-sx700-g-2.jpg

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.

CES 2018: SilverStone's Compact Strider Platinum 1000W and 1200W PSUs

Tagged: CES, CES 2018, Silverstone, PSU, power supply, 80 Plus Platinum, 1000W, 1200w, 140mm, atx, compact, SFF

SilverStone's Strider Platinum lineup now includes 1000 and 1200 watt models with a depth of only 140 mm. These are both fully modular ATX PSUs, and 80 Plus Platinum certified.

DSC_0698.jpg

The compact 140 mm depth is popular with small form-factor builds - and sometimes a requirement for a fully modular PSU like this depending on the enclosure. The power density is obviously getting really high for 2018, and 1200W is likely the highest you will find at 140 mm.

Pricing and release dates have not been revealed just yet for either power supply.

CES 2018: EVGA Shows 2200W 80 Plus Platinum Power Supply

Positioned casually amist the current and upcoming power supply lineup at EVGA's suite at CES is the SuperNOVA 2200 P2, which offers a mere 2200 watts of 80 Plus Platinum power with 183.3A from the +12V rail. I will let that sink in for a moment.

DSC_0711.jpg

Naturally this level of power will require more than the typical 110V mains power in the US, with 220V required. It seems safe to assume that the biggest customer of such a PSU at this point would be the mining community, making the need for 220V a non-issue for the dedicated miners among us (who needs an electric range in the kitchen, anyhow?).

We didn't get specifics on release date or pricing, but this is an impressive piece of hardware - especially considering the Platinum efficiency.

Tagged: Lian Li, SFX, SFX-L, power supply, PSU, small form-factor, 550W, 750w, PE-550, PE-750

Announced back in April, Lian Li has now released a pair of SFX-L power supplies for small form-factor systems with the PE-550 and PE-750. The pair offer fully-modular designs with flat, ribbon-style cables, and carry 80 Plus Gold and Platinum certifications.

The PE-750 power supply

"The PE-550 is 80Plus Gold-rated for a maximum 89.5% efficiency; the PE-750 is 80Plus Platinum-rated for a maximum 92% efficiency. Both use a near-silent 120mm smart fan and minimize noise by operating fanlessly when output power is below 30%. Both PSUs use a single 12V rail design for the best possible stability under heavy system load, matched with myriad protection features to ensure reliable operation."

For more information and full specs, the product page for the 550W PE-550 is here, and the 750W PE-750 page is here. The PE-550 and PE-750 retail for $115 and $169 respectively, and both are available now.

SilverStone Announces SX800-LTI 800W Titanium SFX-L Power Supply

SilverStone introduced a 700W SFX-L power supply at CES in January, and with that SX700-LPT PSU now officially released the company has raised the bar again as no less than 800W is coming to the SFX-L form-factor.

SilverStone's SX800-LTI not only offers a massive 800W, but does so with an 80 PLUS Titanium certification (!). The power supply pushes this massive wattage along a single +12V rail, and the SX800-LTI features a fully-modular design for a clean build. An added benefit to the SFX-L form-factor, other than the potential for these powerful designs, is the use of a 120 mm fan, which allows for much quieter operation under load compared to the smaller SFX variant.

We are now approaching full ATX power with these SFX-L PSUs, and indeed the 800-850W range should be all most users would need for even a dual-GPU system (especially as we enter the era of 14-16nm GPUs with their lower power requirements).

No word yet on price or availability.

Lian Li Debuts SFX-L PE-550 and PE-750 SFF Power Supplies

Lian Li has (rather unexpectedly) announced a pair of SFX-L power supplies, with the PE-550 and PE-750 small form-factor PSUs.

pe750-02.jpg

Lian Li PE-750 SFX-L power supply

SFX-L is the slightly longer (hence the "L") version of SFX, and permits more powerful designs and larger, quieter fans than standard SFX. Of the two new models from Lian Li the PE-550 is an 80 Plus Gold PSU rated at 550W, and the PE-750 is an 80 Plus Platinum model boasting a whopping 750W from this tiny form-factor.

Lian Li has doubtless contracted the manufacture of these PSUs, as the post on SFF Network has concluded: "The 550W at least is from Enhance according to the UL number and the possibly the 750W based on the heatsink design."

pe550.jpg

Lian Li PE-550 SFX-L power supply

The 750W model now bests SilverStone in the SFX power category, eclipsing their 700W SFX-L model shown at CES this year (and which is still not listed on their site). Just why anyone would need 750W for what would presumably be a mini-ITX system (limited as mITX motherboards are, with only one PCI Express x16 slot); but the benefits of SFX are certainly appreciated the moment one begins working inside of an enclosure such as the NCASE M1.

The PSUs are fully modular with flat, ribbon style cables (PE-750 pictured)
