Introduction and Features
Corsair has just expanded their RM Series of PC power supplies to include a third line, the RMx Series, in addition to the original RM and RMi Series. The new RMx power supplies will be available in 550W, 650W, 750W, 850W and 1000W models and are designed by Corsair and built by Channel Well Technologies (CWT). We will be taking a detailed look at the new RM850x 850W PSU in this review.
The RMx Series power supplies are equipped with fully modular cables and optimized for very quiet operation and high efficiency. RMx Series power supplies incorporate Zero RPM Fan Mode, which means the fan does not spin until the power supply is under a moderate to heavy load. The cooling fan is designed to deliver low noise and high static pressure. All of the RMx power supplies are 80 Plus Gold certified for high efficiency.
The Corsair RMx Series is built with high-quality components, including all Japanese made electrolytic capacitors, and Corsair guarantees these PSUs to deliver clean, stable, continuous power, even at ambient temperatures up to 50°C.
Corsair’s new RMx Series power supplies are nearly identical to the current RMi Series units except for these differences:
• Lower cost
• No Corsair Link interface
• 135mm fan vs. 140mm fan
• Additional 550W model
The following table provided by Corsair gives a good summary of the differences and similarities between the RM, RMx, and RMi Series power supplies.

Tagged: qotom, fanless, Broadwell, SFF
FanlessTech found quite a few models of small form factor PCs on Amazon and, while it's not listed in the specifications, some of the manufacturer Q&A responses state that they are fanless designs. Each of these devices are built around the Broadwell Core i7-5500U, but that might not even be the best part. Each PC has 4x USB 3.0, 2x HDMI, and 2x Gigabit Lan. Dual LAN and Dual HDMI opens up quite a few possibilities for a cheap, silent PC, especially since it has a relatively high-performance processor.
Prices range from $360 to $444 for 2GB of RAM and 8GB up to 256GB of SSD storage (with several models between). A single 8GB RAM model, with a 256 GB SSD, is also available for $483. They also found one with an i3 processor, but you need to bring your own RAM, SSD, and WiFi. It does have the same port layout, four USB 3.0, two HDMI, and two gigabit LAN, but might make more sense to grab the Core i7 versions unless you already have DDR3L RAM and an SSD hanging around (or 2GB is insufficient and the 8GB model is out of your price range). At $221 USD plus these components, you probably will not be saving much to compensate for the drop in performance. You can also find some Core i5 models, too.
Quite a bit to consider, but I think that many would benefit from the thought.

Tagged: CRYORIG, H7, air cooling
[H]ard|OCP just strapped another of CRYORIG's coolers to their test bench, this time the H7 CPU Air Cooler. This model is smaller than the one they previously reviewed, a mere 711g in weight and 98x123x145mm (38.5x48.4x57") which offers more compatibility with cases but is not quite in the SFF category. It will fit modern AMD sockets as well as LGA 115X and while it is nowhere near the most effective cooler [H] has reviewed it is the most cost efficient making it a great choice for a gamer looking for something better than stock cooling which won't break the bank. See the CRYORIG H7 in action right here.
"CRYORIG mates its Hive Fin Technology with a smaller design that allows for better RAM module fitment without interference with its H7 CPU Air Cooler. Its "compact" 145mm tall design, excellent mounting configuration, and dollar value are winners for sure. Its new Quad Air Inlet fan design gives us high hopes about its performance."

Cooler Master has "announced the availability of" six power supplies in their “V” series. They are high efficiency products that are fully modular with flat cables for routing. They each use “100% high quality Japanese capacitors” and introduce “exclusive 3D Circuit Design”. Models are available in 550W, 650W, 750W, 850W, 1000W, and 1200W. The highest-end one was announced a while ago, back in 2014, but the line is now available and larger.
The V550, V650, V750, V850, and V1000 each carry an 80PLUS Gold certification for efficiency, while the V1200 is rated at 80PLUS Platinum. Cooler Master claims that their 3D technology, which uses full, separate circuit boards to distance noisy circuits from each other, provides three benefits. First, it reduces heat and improves heat dissipation. Second, it reduces inefficiency that could be introduced by signal noise, which sounds a bit weird for direct current but makes a bit of sense. Third, the reduced ripple and noise can lower long-term stress on the capacitors, which definitely does make sense to me.
Five of the six power supplies come with five-year warranties (the 1200W has a seven-year one). They are available now and range from around 90$ USD to around 300$ USD. The V1200 is currently 30$ off at 270$ USD on Amazon.

Tagged: arbor, fanless, ruggedized
This is an interesting product for a couple of reasons. First, it uses the fourth-generation Haswell processors, rather than the newer Skylake or Broadwell components. On the other hand, it uses LGA-1150 components up to the 45W Intel Core i7-4770TE, which explains the lack of Broadwell and Skylake, because only Core i3 Skylake processors fit both of those constraints currently.
The device is rated for -4F to 131F and an undisclosed amount of shock and vibration. They support 2.5” drives, but the site only lists Intel SSDs. You would probably not want a spinning hard drive in a PC that you are concerned about shock and vibration tolerances. It also supports up to 16GB of DDR3 (again, Haswell) RAM, which should give you a fairly robust system to leave running in the middle of nowhere.
Like other systems that we've seen earlier, the case itself acts as a heatsink, which brings the product's weight up to 14.1 pounds. When you deal with these types of cooling solutions, it's difficult to tell whether they are rated with still air, or a sufficient breeze to carry the heat away from the case fins. It's not something that's advertised.
No pricing or availability is listed.
Introduction and Technical Specifications
Water cooling has become very popular over the last few years with the rise in use of the all-in-one (AIO) coolers. Those type of coolers combine a single or dual-fan radiator with a combination CPU block / pump unit, pre-filled from the factory and maintenance free. They are a good cooling alternative to an air-based CPU cooler, but are limited in their expandability potential. That is where the DIY water cooling components come into place. DIY water cooling components allow you to build a customized cooling loop for cooling everything from the CPU to the chipset and GPUs (and more). However, DIY loops are much more maintenance intensive than the AIO coolers because of the need to flush and refill the loops periodically to maintain performance and component health.
With the increased popularity in liquid cooling type CPU coolers and the renewed interest and availability of enthusiast-friendly parts with the introduction of the Intel Z97, X99, and Z170 parts, it was past time to measure how well different CPU water blocks performed on an Intel X99 board paired up with an Intel LGA2011-v3 5960X processor. The five water blocks compared include the following:
- Koolance CPU-360 water block
- Koolance CPU-380I water block
- Swiftech Apogee HD water block
- Swiftech Apogee XL water block
- XSPC Raystorm water block

Tagged: CRYORIG, H5 Universal, heatsink, Hive Fin
The CRYORIG H5 is referred to as Universal as it supports LGA sockets going back to 775 and all AM2/3 or FM2 AMD sockets, significantly more breadth that most coolers on the market. At 110.9x143x168.3mm (4.4x5.6x6.6") it may not fit in every case and the 920g with the fan installed is going to need a sturdy board to support it. [H]ard|OCP tested out the effectiveness of the Hive Fin and Jet Fin features in their review. As it turns out the cooler is not the most effective choice but it is one of the quietest and for the price it is recommended for users that won't be heavily overclocking their CPU.
"The CRYORIG H5 UNIVERSAL heatsink claims to have a Hive Fin Design for Extreme Performance Efficiency and is compatible with a huge number of older and modern AMD and Intel processors. Along with the Hive Fins, we get Jet Fin Acceleration and Turbulence Reduction. Let's however see just how well it cools your CPU."

Tagged: Lian Li, full tower, enclosure, cases, aluminum case
Looking for a super deluxe way to hold just about any size rig? Lian Li has a sophisticated looking option with the new X510 full-tower enclosure.
An all-aluminum case (of course - it's Lian Li!) with a no-nonsense design aesthetic and very roomy interior, the X510 still keeps a fairly trim profile thanks to the omission of 5.25-inch drive bays.
Here are some of the key features from Lian Li:
- Isolated air chambers for efficient cooling
- Fits huge components – 330mm VGA Card, 180mm CPU cooler, 245mm PSU length
- Eight expansion slots
- Support for eight total drives
- Tempered glass window for showing off hardware
- Included fan speed controller
The glass side window and included fan controller are nice touches, and while the X510 carries a steep MSRP it doesn't seem out of place for an all-alumimum case like this (depending on performance). So what is pricing/availability? The X510 should be available later in September for $399.

Tagged: water cooling, kryographics, GPU Water Block, copper, aqua computer
AMD officially launched its R9 Nano graphics card last week, and aftermarket coolers are already starting to ship. German-based Aqua Computer is the first company to offer a custom cooler for AMD’s pint-sized powerhouse. The Kryographics R9 Nano is a full cover water block that takes the already tiny card to a single slot design.
The Kryographics R9 Nano cooler is a machined copper block that covers the entire PCB and is paired to the VRMs using thermal pads and the GPU (and HBM) using thermal compound. The single slot cooler comes in two options including a see-through translucent ruby colored acrylic glass variant and a version with a brushed stainless steel top cover. In all cases, the block itself is all copper with microchannels over the GPU portion.
The cooler uses standard G1/4 threading on the ports and is compatible with CrossFire multi-GPU watercooled setups by removing the terminating screws and adding ports on the oppposite side of the card..
According to Aqua Computer, the Kryographics cooler was able to keep the R9 Nano GPU under 35 degrees C throughout their testing using Furmark. It will be interesting to see if the new cooler would allow the chips to maintain higher clockspeeds, especially with the power target maxed out in CCC. The need to fit a radiator, pump, and tubing in the case does while still needing to use a Nano (in lieu of a Fury X) makes this a niche within a niche product, but I’m sure some enthusiast will find a use for it!
The Kryographics R9 Nano is available for purchase now (though there is currently a shipping delay of 10 days). The base version without the see-through window has an MSRP of 89.90 EUR while the Kryographics Acrylic Glass Edition has a slight premium at 99.90 EUR. (At the time of writing, that pricing works out to about $102 and $113 USD respectively.)

Tagged: HDPLEX, h5, fanless
FanlessTech has another look at the HDPLEX H5. Their last preview did not have pictures of the case itself, so I needed to use a photo of the previous model when I wrote up our coverage of it. This time, seven whole months later, we have more details. It will weigh eight kilograms, its supported CPU cooling performance has been bumped up five watts to 95W TDP, and it will mini-ITX, microATX, and even full ATX motherboards.

The chassis has 16 heat pipes connected from the case, which acts as a heatsink, to the internal components -- eight pipes to the CPU and eight to the discrete GPU (if installed). This makes it an effective home theater PC case, accepting CPUs up to the Intel Core i7-6700K (which is 95W). The same number of heat pipes go to the GPU, but that TDP is not listed. If it is similar to the CPU's 95W limit, that doesn't go too far in GPU land. Don't expect to passively cool a 980 Ti or anything. Still a discrete GPU of any magnitude is a nice addition to a fanless PC.

One minor point before we close out, HDPLEX will apparently support custom aluminum power buttons and face plates. It's a small novelty but it could be nice if the system is in a visible location.
The HDPLEX H5 doesn't have a release date yet, but its price will apparently be under $300.
