HDPLEX CES Update

Larry from HDPLEX is in Vegas attending CES and Drew, our man on the ground covering the show, was able to catch up with him and get some updates on the upcoming AC-DC and DC-ATX units. For those unaware of the company, HDPLEX develops a line of fanless cases plus the cooling and power solutions to make them feasible, along with accessories like an ultra-flexible PCIe extender. The “NanoATX” power supply line consists of internal AC-DC adapters (that take AC in and output 19V DC) and DC-ATX units that take 16-24V DC input and convert it to the various voltages and connectors need …

SilverStone SX800-LTI Review

It hasn’t even been a full year since the SX700-LPT came out, and yet Silverstone has already one-upped themselves on both wattage and efficiency with their just-released unit, the SX800-LTI. For those not familiar with Silverstone’s current SFF PSU model number scheme, that amalgam of numbers and letters translates to a 800W, SFX-L form factor, Titanium-rated efficiency, fully-modular power supply. Yes, seriously. But before we dive into our review, the backstory for this unit is quite interesting in and of itself, as it was less than a week after my SX700-LPT review (a 700W, Platinum-rated unit) went up – when I was wrapping up …

Enermax to launch Revolution SFX series of power supplies.

On December 9th, Enermax will launch their new Revolution SFX series of power supplies. Available in 550W and 650W variants, these 80-Plus Gold, fully modular power supplies are yet another welcome addition to the SFF market. With semi-fanless operation up to 30% utilization, the offset 80mm fan will (hopefully) help to provide quiet operation depending on the system load. This unit appears to be based on the same Enhance Electronics platform as the SilverStone SX600-G, Thermaltake STP-0600F-G, and Lian-Li PE-550 though so it will remain to be seen if Enermax has improved on the fan controller deficiencies inherent to the platform. Edit1: or maybe not. …

SilverStone SX700-LPT fan controller revision

I noticed during extra testing of the SX700-LPT SFX-L power supply from SilverStone that I could trigger the Over Temp Protection with a heatgun before the fan kicked on. After asking SilverStone about it, I learned that the fan controller was set to only turn the fan on above 150W load to ensure that the semi-fanless feature really worked. I imagine this was done due to user complaints about the SX600-G and SX500-LG v1.0/v1.1 where the simple thermistor-based controller would cause the fan to turn on even at low loads after the power supply warmed up to operating temperature inside …

Thermaltake releases the Toughpower SFX Gold Series PSUs

Thermaltake announced today the release of their Toughpower SFX Gold Series line of power supplies, with a 450W and a 600W unit. They’re Gold-rated for efficiency, fully-modular with flat cables, semi-fanless (we’ll see), and feature all-Japanese capacitors. While it’s nice to see more options in the SFF PSU market, these units look to be based on the same Enhance platform as the SilverStone ST45SF-G and SX600-G. While those SilverStone units were best-in-class at the time of their release, that time was also 4 years ago for the 450W and 2 years ago for the 600W. SFF enthusiasts are often picky when it …

John’s Weekly Mini-Rant – SFX, The New Standard

This is one of a series of weekly mini-rants by your faithful correspondent, John Morrison. These is a regular series focusing on issues in the SFF niche. All content is entirely opinion of John, not of SmallFormFactor.net, and should not be taken as fact. Silverstone and Lian-Li have made this rant possible by releasing what I consider the tipping point for SFX – capacities greater or equal to 700w. It’s at this point that the ‘bigger is better’ community (those with CaseLabs cases, etc) will hopefully stand up and take a second look at what they are doing. 700 watts should be enough …

Raijintek shows off “Micro ATX” and SFX PSUs

Raijintek is probably a name that isn’t super familiar to SFF enthusiasts, but they’ve been making inroads into the market with their ITX Metis and mATX Styx cases. At Computex, they’re showing off new power supplies that are of interest. First are the so called “Micro ATX” units. I’m not fond of the name because the term “Micro ATX” or “mATX” for power supplies is confusing since it’s not an actual standard and it has also been used to describe power supplies of the SFX and ATX PS/3 form factors. Quibbles about the name aside, they are ATX power supplies …

SilverStone SX800-LTI – 800W Titanium SFX-L!!

Edit: Our review of the SilverStone SX800-LTI here. In the course of research for the Lian Li PE-750 review, I ending up checking the UL manufacturer directory listing for SilverStone and noticed references to a SX800-LTI. As I went over in the SX700-LPT review, according to SilverStone’s current SFF PSU nomenclature, the “SX800-LTI” model number translates to a 800W SFX-L Titanium-rated fully-modular power supply. Curious if this was real I contacted Tony Ou, SilverStone’s marketing manager, and even though he’s busy with Computex, he replied that it is indeed real, they announced it today, and it will (hopefully) be available in …

Lian Li PE-750 Review – An Unexpected Entrant

Lian Li is renowned for their aluminum computer cases, but they’ve also offered power supplies at various times, either as standalone units or as PSU’s that were bundled with certain cases. However, it hasn’t been a product category they’ve really pushed in the last several years – so it was about as expected as the Spanish Inquisition for Lian Li to suddenly announce two high-wattage SFX-L power supplies, which is exactly what they did early last month. The two new SFX-L units they first shared with the world in April were the PE-550 and the PE-750, and it’s the latter of which that is the subject of today’s …

SilverStone SX700-LPT Review – It’s Finally Here!

This review has been a long time in the making. The SilverStone 700W SFX-L power supply – that later came to be designated the SX700-LPT – was first shown off ahead of the last Computex on May 27th, 2015, almost exactly a year ago. Since then, the PSU has made appearances at various industry conferences and events, as if to tease us. But now, the time has finally come, and the SX700-LPT is here! So what exactly is the SilverStone SX700-LPT? To explain this, I’d like to break down the model number because it contains the information we need, I’ve seen some …

Lian Li Stealth Launches the PE-750: A 750W Platinum SFX-L PSU

Who doesn’t love unexpected surprises? Eagle-eyed member of the forum iFreilicht has turned our attention to a new listing on Newegg for Lian Li’s highly-anticipated PE-750, which currently lays claim to the title of the highest wattage SFX-L power supply available, let alone the highest wattage SFF-oriented PSU more broadly. Most know of Lian Li as a manufacturer of popular (if not occasionally curious) aluminum enclosures, so the company’s entry into the power supply market is a notable departure from their traditional offerings. SFF Network actually covered the unexpected announcement of the unit (alongside a 550W Gold-rated SFX-L PSU) in early April, and the development took the industry …

Lian Li announces two SFX-L power supplies

Known for their quality aluminum cases rather than power supplies, today Lian Li announced two SFX-L power supplies, the Gold-rated 550W PE-550 and the Platinum-rated 750W PE-750. There is basically no information on these units available other than what’s listed on Lian Li’s website. They both share grill designs, what appears to be the same slim 120mm fan as the SilverStone SX500-LG, full modularity, and  relatively short flat ribbon cables. Also, to avoid any confusion, despite the tagline in the marketing image these units are SFX-L, not SFX. The listings for both units mention that the fan voltage varies with both temperature …
