Gigabyte Teases New Power Supplies

Tagged: modular psu, gigabyte, ATX PSU

Gigabyte made an announcement teasing two new power supplies last week. The G750H and B700H are 80 PLUS rated models topping out at 750W and 700W respectively. A company most well-known for its motherboards, it was somewhat surprising to see it tease power supplies and to discover that these PSUs are not even the first to be sold by Gigabyte with its branding.

The G750H and B700H are ATX form factor and use a semi-modular design that leaves the 24-pin ATX and 8-pin CPU power cables permanently attached and uses modular cables for all other connections (see below). One neat thing is that Gigabyte is using all black flat individually sleeved cables which may make it easier to hide and route them behind the motherboard tray (which on some cases can be an especially narrow channel). Both models are rated for SLI and Crossfire multi-GPU setups, use at least some Japanese capacitors (the G750H uses all Japanese capacitors), have a MTBF of 100,000 hours, and five year warranties.

In addition to the motherboard and CPU power, users can install two eight pin PCI-E, five SATA power, three Molex, and one floppy power connector. The modular cable configuration is the same on both PSU models.

The G750H is up to 90% efficient (80+ Gold) and uses a 140mm temperature controlled fan to keep noise levels low and the internal components cool (and efficient). Gigabyte has opted for a single rail design that sees the 12V rail rated at up to 62 amps.

On the other hand, the B700H is up to 85% efficient (80+ Bronze) at typical loads. It has a smaller 120mm temperature controlled fan for cooling. This model also uses a single 12V rail, but it tops out at 54 amps.

Several sites around the Internet have indicated (including Maximum PC) that Gigabyte has made the G750H and B700H available now, but they do not seem to be for sale yet in the US. I have tried to unearth pricing as well as the identity of the ODM Gigabyte is using for these new units, but no such luck so far. From my research, it appears that Gigabyte has used a number of different ODM/OEMs of varying quality for their past power supplies. It seems that we will have to wait for reviews to know for sure how these new PSUs will perform. I hope that Gigabyte has stepped up its power supply game as it has quite a bit of competition these days!

Introduction and First Impressions

The Scythe Ninja 4 (SCNJ-4000) is the latest model in the Ninja series, and an imposing air cooler with dimensions similar to Noctua's massive NH-D14. But there's more to the story than size, as this is engineered for silence above all else. Read on to see just how quiet it is, and of course how well it's able to cope with CPU loads.

NINJA4-Side_View.jpg

"The Ninja 4 is the latest model in the Ninja CPU Cooler Series, developed for uncompromising performance. It features the new T-M.A.P.S technology, an optimized alignment of heatpipes, and the back-plate based Hyper Precision Mounting System (H.P.M.S) for firm mounting and easy installation procedure. These improvements and a special, adjustable Glide Stream 120mm PWM fan result in an increased cooling performance while reducing the weight compared to his predecessor. Also the design of the heat-sink allows fan mounting on all four sides. This enables the optimal integration of the Ninja 4 in the air flow of the pc-case and reduces turbulence and the emergence of hotspots."

The Ninja 4 is built around a very large, square heatsink, which allows the single 120 mm fan to be mounted on any side, and this PWM fan offers three speed settings to further control noise. And noise is really what the Ninja is all about, with some really low minimum speeds possible on what is a very quiet Scythe fan to begin with.

Will a single low-speed fan design affect the ability to keep a CPU cool under stress? Will the Ninja 4's fan spin up and become less quiet under full load? These questions will soon be answered.

The Azza Nova 8000 certainly stands out in the crowd

Tagged: azza, Nova 8000

You have to take a look at several pictures of the Azza Nova 8000 before you truly understand just how the orange and black case looks; to then decide if it is hot or not.  The swing out doors which allow you to access your drives are a unique feature but arguable one of limited usage. Leaving the aesthetics behind, the case supports up to E-ATX boards at 589x221x574mm (21.6x8.7x22.6") in size and supports up to four 120mm fans or up to a 360mm radiator at the top and a 240mm one on the bottom.  With up to 13 drives supported the case is certainly aimed towards the data pack rat and helps to explain the drive chambers somewhat, but not so much the colour scheme.  Check out the full review at Overclockers Club if the picture below doesn't immediately scare you off.

"The fit and finish of this case is top notch. All the panels lined up and fit together nicely. The top I/O panel gives you two USB 3.0 and two USB 2.0 ports, which is fairly standard on a case this size, and the colorful LEDs break up the monotony you find with many cases that use single-color LEDs. And while I am talking about LEDs, the gentle orange glow from the front fan adds a nice touch."

Introduction and Features

Introduction

2-Banner-1.jpg

Earlier this year we took a detailed look at the Silent Base 600 and found it to be a full-featured mid-tower enclosure that focuses on quiet, virtually silent operation, while at the same time delivering excellent cooling performance, usability and support for high-end hardware. Be Quiet! introduced the Silent Base 800 mid-tower case well over a year ago and later released the Silent Base 600 mid-tower case in 2015. The two cases are functionally very similar with only a few minor changes differentiating the two. Because the two cases are so similar, we are going to highlight the Silent Base 800’s features and specifications and then point out the main differences using the Silent Base 600 as a reference.

Be Quiet!’s Silent Base Series currently includes two cases; the Silent Base 800 and the Silent Base 600. As you might expect, the Silent Base Series is designed for very quiet operation while still offering excellent performance and cooling. Both cases are targeted towards users looking to build a quiet high-end gaming or multimedia system.

Fractal Design Introduces Define Nano S Mini-ITX Enclosure

Subject: Cases and Cooling | January 18, 2016 - 05:39 PM |
Tagged: small form factor, silent case, SFF, mini-itx, fractal design, enclosure, define s, define nano s, case

Fractal Design has introduced the Define Nano S enclosure; a new, mini-ITX version of their popular Define S mid-tower.

nano1.jpeg

The Fractal Design Define S was our pick for 2015 enclosure of the year (in our year-in-review podcast), and this new mini-ITX version retains the larger enclosure's design aesthetic - and its support for full-size components.

nano3.jpeg

"The Define Nano S is an ITX case that features compatibility with high end, full-size components, superior sound dampening, and an ATX-like layout."

Key features for the Define Nano S from Fractal Design:

  • A Define Series ITX case designed for silent computing with sound dampening and ModuVent™ technology
  • User-friendly construction with superior cable management and compatibility for full-size components
  • Flexible storage options with room for up to 4 drives
  • Accommodates a variety of radiator sizes and includes brackets for reservoir and pump mounting
  • Features two Dynamic Series fans — 1 GP-12 and 1 GP-14 — with an adapter included for motherboards with limited fan headers
  • Featuring an open interior allowing an unobstructed airflow path from the front of the case to the rear exhaust
  • Easy-to-clean filters on the top and bottom, spanning the PSU position, with the bottom filter ejecting from the front for easy-access.

nano2.jpeg

The Define Nano S offers a great deal of room for a mini-ITX enclosure (the Nano S is approximately 13.5 inches high, 8 inches wide, and 16.2 inches deep), with support for up to a 240/280 mm radiator on both top and front fan mounts, with 6 fan mounts overall (two of Fractal's Dynamic Series fans - 120 mm and 140 mm - are included). And an important detail; both the bottom and front fan mounts feature removable dust filters.

The enclosure offers the same "ModuVent" removable top vents, allowing more silent operation if the user doesn't need to use the upper fan mounts. There is sound dampening in place throughout, allowing for a quiet build. Storage mounts are behind the rear panel (as in the Define S) supporting two each 3.5-inch and 2.5-inch drives. GPUs up to 315 mm and CPU coolers up to 160 mm are supported along with ATX PSUs up to 160 mm deep.

Fatal1ty lends his Firepower to this 750W PSU

Subject: Cases and Cooling | January 14, 2016 - 08:44 PM |
Tagged: modular psu, firepower 750W, fatal1ty, 80 Plus Gold

Bear with us on this one as there is a long strange story behind the new PSU maker which calls themselves Firepower.  A long time ago was PSU maker that ruled the roost who called themselves PC Power & Cooling, charging a premium over the competition but being worth every penny.  As the markets changed PCP&P found themselves lagging and so an apparently successful company called OCZ purchased them wholesale and begat their own line of PSUs.  Sadly all was not as it seemed at OCZ, the deals they offered were indeed too good to be true and to survive they had to amputate some portions of themselves and sell them.  The PSU portion, including the patents, was sold in 2014 to a new company which called themselves Firepower Technology and so we come to the FirePower Fatal1ty 750W.

This PSU is rated as a 80 Plus Gold model with a 5 year warranty which speaks to the confidence of Firepower.  It uses a single 12V rail capable of delivering 62.5A and the modular cables include four 6+2 PCIe, six Molex , and eight SATA connectors, enough to power a dual GPU system. [H]ard|OCP cracked the PSU open and found it to be the same design as a SilverStone ST75F-GS V2 with a mix of components, none of which stood out as being top of the line.  In the end the design was good enough to pass every test [H] threw at it but with a relatively high price it did not come off with an award.

"The Fatal1ty Series PSUs by Firepower Technology may seem to be something new in the world of computer power supplies, but really it is not. That said, Firepower is somewhat new in the PSU world, so let's see where they are headed right now."

BitFenix Introduces Spectre Xtreme Fans for CPU Coolers

Subject: Cases and Cooling | January 14, 2016 - 06:59 PM |
Tagged: bitfenix, case fan, cpu fan, static pressure, air cooling, Spectre Xtreme

BitFenix has introduced a line of Spectre dual-frame fans based on the Pro series with their new Xtreme high static pressure fans. These are made with CPU cooling in mind, and are available in both black (without LEDs) and multiple color LED options.

SX-Blk-MasterImage.png

The Spectre Xtreme fans operate from 950 - 2000 RPM with newly-designed fan blades for airflow up to 66 CFM with "optimum static pressure", making them "an ideal choice for liquid cooling solutions". The fans use fluid dynamic bearings for reduced noise levels, as well as increased efficiency and life expectancy, according to BitFenix.

BFF-SXTR-12025K-RP (1).jpg

"With the introduction of dual frame design of the BitFenix Spectre Pro series we raised the standards of system fans to a new level. The new BitFenix Spectre Xtreme fans offer many features redefining the standards of cooling fans. Spectre Xtreme gives you the best performance and aesthetics using the latest in cooling fan technology and innovative designs.

Cooling fans used in liquid cooling systems not only need to have a high airflow but also they need to be optimized for static pressure. The newly designed blades of the Spectre Xtreme not only look good but also improve the airflow of the fan to 66CFM while maintaining optimum static pressure. This makes the Spectre Xtreme fans an ideal choice for liquid cooling solutions."

Visual differences between Revision 1.0 (left) and Revision 1.1 (right) (via EKWB)

EKWB is also taking responsibility for any component damage that may have resulted from any leaks, offering refunds for defective units (if a replacement is not desired) and affected components.

From EKWB:

"All Revision 1.0 units produced from October 2015 until end of December 2015 are potentially affected by the risk of leakage and in order to prevent any computer component damage, the units need to be replaced. The leakage may occur between copper cold plate and bracket on the water block after it is heated up and pressure rises. Current statistics show that 1 out of 10 units leaks.

We are warning all customers of EK XLC-Predator units to discontinue use of cooling device and contact EKWB for replacement unit or refund. EKWB is taking full responsibility for this issue and will be:

  • Replacing or refunding all returned units to the customers
  • Refunding the customer any computer component damage created by a leakage

EKWB has redesigned and released a new version of EK-XLC Predator (Revision 1.1) on the 4th of January 2016 that prevents any leakage under normal working modes. All customers with Revision 1.0 units will be offered a replacement R1.1 unit or a full refund. Revision 1.0 backplate is not compatible with Revision 1.1 backplate!"

SilverStone Displays Early Mini-STX Enclosure

Tagged: small form factor, Silverstone, SFF case, mini-stx, Intel 5x5, enclosure, CES 2016, CES

SilverStone had an early enclosure on display at CES for the upcoming Mini-STX standard, the tiny form-factor introduced with Intel's "5x5" motherboard (which we first reported on almost exactly one year ago).

DSC_0191.jpg

The simple black metal enclosure (as yet unnamed) looked and felt like a production unit, but we are still in the early stages with the first mini-STX motherboards being announced only this week. No details were given on when it would be available for purchase, or exactly how much it will cost.

DSC_0193.jpg

It is interesting to note the enclosure's I/O, which should indicate the standard for the new motherboards. On the front panel we had openings for a standard USB and Type-C port, and 3.5 mm audio; around back there were two more USB ports, LAN, DisplayPort, and HDMI. To the left of the HDMI port you can see the power input for the external power supply, as mini-STX will have a lot in common with the thin mini-ITX standard. (Thin mini-ITX optionally supported internal PSUs, but given the space constraints it looks like the mini-STX boards will be using a laptop style power supply.)

We will await any official announcement of this (and any other) upcoming mini-STX enclosure from SilverStone.

Tagged: workstation, standing desk, Lian Li, enclosure, DK-04, desk chassis, CES 2016, CES, aluminum case

Lian Li has introduced a new electronic sit/stand desk chassis, the DK-04, which holds a full system under its tempered glass surface and raises and lowers at the push of a button.

DSC_0312.jpg

On display at their booth at CES last week, the DK-04 offers a compelling option for someone interested in a standing workstation, with the added benefit of housing a powerful custom rig (and looking really cool in the process).

DSC_0316.jpg

There is room under the glass desktop (this model does not use a drawer) for up to an ATX motherboard with one dual-slot expansion card, which can be used with a GPU up to 320 mm in length. CPU coolers of up to 120 mm are supported, along with 120 mm width radiators up to 480 mm long.

DSC_0313.jpg

The front panel offers 4x USB 3.0 ports, RGB lighting controls, and a 5.25-inch optical drive bay; and there is internal storage support for up to 8x 3.5-inch or 2.5-inch hard drives. The entire unit is 47.24 inches wide, 29.53 inches deep, and can be adjusted from approximately 30 - 46 inches in height.

DSC_0314.jpg

The control panel for the electric height adjustment includes the option for up to 4 presets, allowing the desk to easily adjust to various pre-defined seated and standing positions.

Pricing and availability have yet to be announced, but expect this to come in higher than IKEA's popular solution (which doesn't offer a the functionality of a full PC enclosure inside, of course).
