Nixeus is not a household name by any means but they could heat up competition in the mechanical keyboard market as a new player using relatively new Kailh Brown switches.  Like many ten-keyless gaming boards it has extra blue key caps to make your board more interesting, gold plated USB connectors, a 1000Hz Poll Rate and 6 Key Roll-over.  The Kailh Brown switches are clones of Cherry MX Brown switches and felt almost the same when Legit Reviews tested them.  The keyboard is similar to many already on the market but should appeal to those who prefer simplicity over media buttons and LEDs.

"Founded in California of 2009, Nixeus is still a bit of a newcomer to the PC hardware industry looking to build up a bigger name in the world of monitors and peripherals. Their aggressively priced 1440p monitors which carry the same LG panels found in the iMac displays have been their mainstay for much of that time, but recently Nixeus is expanding to the PC gaming market including the Moda mechanical keyboard being reviewed here on Legit Reviews. Read on to see how this keyboard performs!"

Manufacturer: Seasonic

Introduction and Features

2-Banner.jpg

Seasonic is a well known and highly respected OEM that produces some of the best PC power supplies on the market today. In addition to supplying power supplies to many big-name companies who re-brand the units with their own name, Seasonic also sells a full line of power supplies under the Seasonic name. The new XM2-1250 is the latest addition to the X-Series and features an improved Hybrid Fan control circuit and upgraded copper conduction bars on the main PCB, which together increase efficiency and performance.

The new XM2-1250 is a second generation X-Series power supply that comes with fully modular cables and a 120mm Sanyo Denki cooling fan. It is designed to provide ultra-tight voltage regulation along with high efficiency (80 Plus Gold certified).

Seasonic X-Series XM2-1250 Special Features

Ultra Tight Voltage Regulation Improved load voltage regulation keeps the voltage fluctuations on the 12V output within +2% and -0% (no negative tolerance), and on the 3.3V and 5V outputs between +1% and -1%, which (under 80 Plus load conditions) results in smooth and stable operation.

Seasonic Hybrid Silent Fan Control The industry first, advanced three-phased thermal control balances between silence and cooling. The Hybrid Silent Fan Control provides three operational stages: Fanless, Silent and Cooling Mode.  In addition, a selector switch is provided to allow for manual selection between the Seasonic S2FC (fan control without Fanless Mode) or S3FC (fan control including Fanless Mode).

Reduced Cooling Fan Hysteresis is achieved by a new fan control IC, which optimizes how frequently the fan switches on and off. At 25°C ambient temperature the fan turns on when the load rises above 30% (±5%) and turns off when the load drops below 20% % (±5%). Due to this lag in response the fan switches on and off less frequently, which reduces power loss in Fanless and Silent Mode.

Dual Copper Conduction Bars on the power supply PCB help reduce impedance and minimize voltage drop, which further improves efficiency and performance.

80Plus Gold The XM2-1250 power supply is certified in accordance to the 80PLUS organization's Gold standards, offering performance and energy savings with up to =90% efficiency and a true power factor of greater than 0.9 PF.

Full Modular Design (DC to DC) The Seasonic X-Series power supplies feature an integrated DC connector panel with onboard VRM (Voltage Regulator Module) that enables not only near perfect DC-to-DC conversion with reduction of current loss/impedance and increase of efficiency but also a fully modular DC cabling that enables maximum flexibility of integration and forward compatibility.

BioStar's Hi-Fi Z97WE motherboard

Tagged: biostar, z97, Hi-Fi Z97WE

BioStar's Hi-Fi Z97WE is so named for the EMI shield over the Realtek ALC892 audio codec though on the board The Tech Report tested it was less than effective at blocking noise from interfering with the headphone out when the GPU was under heavy load.  On the other hand the Digital S/PDIF audio out is rare to see on a lower priced motherboard and will be attractive to some users, even with the lack of digital encoding. The two PCIe 16x slots can handle dual GPUs at 8x speeds but perhaps the most attractive feature is the M.2 slot for an SSD to be inserted.  Check out how well it overclocks and the overall stability of this $124 motherboard in the full review.

"Biostar's latest Haswell motherboard sells for only $125, but it's specced like pricier alternatives. You get an overclocking-friendly Z97 chipset, PCIe slots primed for multi-GPU configs, an M.2 slot for next-gen SSDs, and upgraded audio hardware. We spent some quality time with the Hi-Fi Z97WE to see what it's really like, and you might be surprised by what we learned."

HGST Announces 12 Gbps SAS, Enterprise SSDs

Subject: General Tech, Storage | July 29, 2014 - 07:24 PM |
Tagged:

You might remember Allyn say that Samsung's 850 Pro is the closest to total saturation of SATA 6Gbps. The other option that we have seen is the bunch of SSDs that are attached to a PCI Express bus. HGST, formerly Hitachi Global Storage Technologies, has just SAS'd back (that was a terrible pun... which I refuse to apologize for) with a Serial Attached SCSI 12 Gbps model (pdf link). They claim a maximum read throughput of 1100 MB/s, with 64K chunks, and 130,000 IOPS, with 4K random accesses.

HGST-12gb-SSD.jpg

The drives will be based on Intel 20nm enterprise-grade NAND with two bits per memory cell (MLC). Its durability is rated at 25 full driver writes per day for 5 years. Models will range from 100GB, all the way up to 1600GB (1.6TB).

While I am limited to Google Translate, there does not appear to be any price or availability information provided. They are enterprise drives, however, so I expect it to be above typical consumer drives.

Introduction, Specifications and Packaging

Introduction:

A few months back, we took a look at the ADATA Premier Pro SP920 series of SSDs. Those came equipped with the Marvell 88SS9189 controller. Marvell SSD controllers have always done a good job, and they were among the first to support SATA 6Gbit speeds. Crucial was one of the first to adopt the Marvell controller into their SATA SSD products, so it seems fitting that we revisit the 88SS9189 controller in the form of Micron's Crucial M550 Series of SSDs:

Being one of the big manufacturers of SSDs, Micron has some cool production videos. Here's one of their videos covering the production of flash all the way through to the assembly of an SSD. We actually toured one of these plants a few years back. Good stuff:

Oculus Rift Dev Kit 2 is starting to arrive, more pixels and less screen door

Subject: General Tech | July 28, 2014 - 02:37 PM |
Tagged: oculus rift, DK2, oled, kick ass

The two top improvements in the second Oculus rift are aimed to reduce the screen door effect by changing the display to a full 1080p OLED screen and the inclusion of Valve's low persistence of vision feature to reduce the image smearing that DK1 users reported.  There is a brand new way of tracking your heads position in 3D with the DK2, a camera tracks the motion of hidden onboard IR LEDs to track translational movement in addition to the rotational tracking existent on the DK1.  You will need 2 free USB ports and it connects to an HDMI or DVI port on your GPU, wireless video streaming is still a hurdle for many applications let alone the Oculus Rift.  Check out the comments on Slashdot and follow the link for a full preview.

"The hotly anticipated Oculus Rift DK2 has begun arriving at doorsteps. The DK2s enhancements include optical positional tracking and a higher resolution panel, up from 1280×800 to 1920×1080 (1080p) and moved to a pentile-matrix OLED panel for display duties. This means higher levels of resolvable detail and a much reduced screen door effect."

Two drives are competing for the budget segments money on Legit Reviews, the $250 Corsair Force LX 512GB and the $240 ADATA SP610 512GB SSD.  512GB should be enough for most budget users to store their needed software on and save them the cost of an HDD but which will offer the most value for the money?  Both drives have Silicon Motion's SM2246EN controller and 20nm Micron MLC NAND, the same 3 year warranty and the same physical measurements.  Does one stand out over the other?  Read the full review to see.

adata-sp610-corsaid-force-lx-645x320.jpg

"Solid-State Drive (SSD) have been steadily growing in capacity and thanks to improvements to the manufacturing processes the price of NAND and SSD controllers has been falling at an impressive rate. This means that fairly large SSDs are now fairly affordable and something the for the average consumer can justify purchasing."
