Corsair has upped their presence in the cooling field with the new 140mm fan-based additions to the Hydro Series™ CPU water cooler lineup. Corsair was kind enough to provide us with samples of their H90 and H110 series cooling units, both using 140mm fans. We put these coolers up against their H80i 120mm fan-based unit as well as our custom-built Swiftech Apogee HD cooling system to see how well these new Corsair units performed. Starting at a base price of $99.99 for the Corsair H90 cooler, you can't go wrong with either unit.

Corsair worked with Asetek to design their new 140mm-based line of coolers with the H90 and H110 introduced to enhance their current line of coolers. Both coolers are built using aluminum radiators capable of holding 140mm fans and copper cold plates. The rubber coated tubing used is low permeability 1/4 inch based tubing with multiple layers used to prevent liquid evaporation and to provide maximum tubing flexibility. Unlike their Corsair Link™ based coolers, the Corsair H90 and H110 units do not have integrated LEDs nor the Corsair Link™ based monitoring system.

Manufacturer: EVGA

Introduction and Features

EVGA was founded in 1999 with headquarters in Brea, California. They currently specialize in producing NVIDIA based graphics adapters and Intel based motherboards and they are continuing to expand their product line to include enthusiast grade power supplies, starting with the NEX1500 last year and now adding the SuperNOVA NEX750G and NEX650G models.

Back in September 2012 we reviewed the SuperNOVA NEX1500 digital power supply that delivered 1500 watts of power and came bundled with EVGA’s SuperNOVA software that allows monitoring all of the power supply’s functions in real-time from your desktop. We liked the NEX1500, especially the SuperNOVA monitoring software, so when EVGA asked us to review the new SuperNOVA NEX750G Gold, we said yes and assumed it would incorporate similar features to the flagship SuperNOVA NEX1500. While the NEX1500 PSU was targeted towards an elite few with deep pockets, the new NEX750G and NEX650G models are aimed at more mainstream, cost-conscious consumers. And to our disappointment, neither of the new power supplies feature digital control, so they can't be used with EVGA's SuperNOVA monitoring software.

2-PSUbanner.jpg

Here is what EVGA has to say about the new SuperNOVA NEX 750G Gold PSU: “The EVGA NEX750G Gold PSU is a premium quality power supply intended to meet the needs of the most demanding enthusiasts systems. Designed with enthusiast needs in mind the NEX series is the best choice to power next generation enthusiast computers. Combining 750W of continuous power with exceptional performance, stunning efficiency, and cutting-edge design and features, the NEX750G Gold is what you need to take your system to the next level.

You can also count on EVGA to provide the utmost reliability and performance, with 100% Japanese capacitors and a durable dual-ball bearing fan. The NEX750G Gold is designed from start to finish to be the best choice for today's most demanding enthusiast computers. Bring you’re a-game with the NEX750G Gold power supply!"

The Corsair Hydro Series™ H80i High Performance Liquid CPU Cooler is the middle tier cooler in Corsair's latest revision of the series. We decided to take the cooler apart to see what makes it tick and share insight on the components used in designing this award winning cooler.

03-h80i-flat.jpg

The Hydro Series™ H80i cooling system consists of an aluminum-based 120mm x 120mm x 38mm radiator capable of supporting two 120mm x 120mm fans, attached to a CPU copper-based cooling assembly via 3/8 inch rubber hoses. The CPU cooler contains embedded magnets to better hold the CPU clip to the body of the cooling assembly. The CPU cooler also includes an integrated LED in the top of the assembly as well as Corsair Link™ connection ports and fan connection ports. The cooling hoses are attached to the CPU assembly by rotating nozzles, capable of an almost full 360 degrees of rotation.

Corsair partnered with CoolIT Systems in the design and implementation of the H80i. While the CPU cooler assembly pictured is not exactly like the H80i, the CoolIT Systems designed ECO II is close enough to the H80i in design for comparison purposes. Notice how the top cap and cold plate sandwich the pump assembly in place with the pump and electronics sitting in an upper chamber and the barbs feeding into or fed from a lower chamber.

Quick look at a low cost Carbide

Corsair continues its push into the case markets with yet another option, the Carbide 200R, bringing the price of entry down to sub-$50.  Currently selling on Newegg.com for $45 with a coupon code, check out this quick video walkthrough of the latest case from Corsair!

Video Loading...

After spending a bit more time with the case I can tell that for the price, the 200R is a pretty solid option.  I am not a fan of the 2.5-in drive arrangement that puts the power and data cables out into the case rather than towards the back (like the 3.5-in drives have) just from a cleanliness point of view, but that's somewhat minor.  Also worth noting is that even though we have a $50, and very light chassis, there aren't any sharp edges to cut you; Corsair did a good job rounding off the edges and having the metal fold back for a safe environment. 

There are a TON of case options in the price range so it might be hard for the Carbide 200R to stand out with a simple Newegg/Amazon search, but I think the Corsair brand will help sift it to the top.

Thoughts about Interface Design in General

I have been in several situations where a variety of people claim the gamepad is superior for gaming because that is what it was designed for. No elaboration or further justification is given. The controller is designed for gaming and is therefore clearly better. End of – despite often being start to – discussion in their minds.

Really it is a compromise between the needs of popular games and the environment of a couch.

Interface design is complicated. When you design an interface you need to consider: the expected types of applications; the environment of the user; what you are permitted to use; what tolerances are allowed; what your audience is used to; and so on, so forth. There is a lot to consider when you design an application for a user and I could make an educated guess that it is at least as hard to design the input device itself.

The history of keyboard design is a great example of tradeoffs in input devices.

Sometimes it is better to be worse...

Dvorak.svg_.png

The first wave of keyboards were interfaces to the mechanical typewriter. These keyboards were laid out in alphabetical order because as long as each key is accessible and the user could find the letter they wanted – who cares, right? We already have an order for the alphabet that people understands so the users should not have too much difficulty in finding the letter they need.

Another constraint quickly game to light: typists were too fast and the machines jammed.

The engineers now needed to design an input method which could keep up with the typist. Correcting the machine itself was somewhat futile so the solution was to make the typist as slow as possible. The most common letters in the English language were spread all over the place and – while possibly by fluke – the left hand is favored, as in made do more work, over the often dominant right hand.

The problem required making the most aggravating keyboard layout engineers could imagine. QWERTY was born.

What has been designed to threaten QWERTY? Read on to find out.

Manufacturer: EVGA

Introduction and Features

EVGA might not be the first name that comes to mind when looking for a high-end power supply but they are about to change that with the introduction of the SuperNOVA NEX1500 Classified 1500W power supply. Not only is the SuperNOVA NEX1500 Classified the highest capacity power supply we have reviewed to date, it also comes bundled with EVGA’s SuperNOVA software that allows monitoring all of the power supply’s functions in real-time from your desktop.

EVGA was founded in 1999 with headquarters in Brea, California. They currently specialize in producing NVIDIA based graphics adapters and Intel based motherboards and they are now expanding their product line to include enthusiast grade power supplies, starting with the NEX1500. EVGA plans to add 750W and 650W models to follow.

The EVGA SuperNOVA NEX1500 Classified power supply can deliver up to 1500W combined load while operating on 120VAC mains and can be “overclocked” to 1650W if operated on 240 VAC mains.  It used to be that ~1200W DC output was about as high as you could go on 120VAC mains but as the overall PSU total efficiency has increased higher outputs are now possible. The NEX1500 supports either single or multiple +12V rail modes (DIP switch selectable) and can deliver up to 124A on the +12V rail (133A in OC mode). WOW – you can weld ½” steel plate with 120A!! (OK, I might have trouble keeping the arc stable at 12V, but that is still some serious current.) This bad-boy even comes with a handle and is backed by a 10-Year warranty. And just to tickle your interest, here are a few stats you might be wondering about:
• 1500W Continuous power output @50°C (1650W in OC mode)

Manufacturer: Corsair

Introduction and Features

Corsair continues to bring a full line of high quality power supplies, memory components, cases, cooling components, SSDs and accessories to market for the PC enthusiast and professional alike.  Corsair's updated Professional Series HX power supplies include four models; the HX650, HX750, HX850 and HX1050.  All of the power supplies in the Professional Series feature modular cables, premium quality components, an energy-efficient design (now 80 Plus Gold certified) and quiet operation; and they are backed by a 7-year warranty and lifetime access to Corsair's comprehensive technical support and customer service. The most obvious differences between the new models and the old Professional Series HX PSUs are the new 80 Plus Gold efficiency certification (upgraded from 80 Plus Silver) and the ability to operate in fanless-mode.

Here is what Corsair has to say about their new Professional Series HX PSUs:

"Legendary Performance and Reliability

Corsair Professional Series HX power supplies are designed for PC builders and upgraders who need a highly efficient, quiet, and supremely-reliable power supply, with a modular cable-set that makes installation a breeze.

Quiet Operation at Low Loads

Thanks to their highly-efficient design, Corsair Professional Series power supplies generate minimal heat, and are able to operate in a silent, fully-fanless mode at up to 20% of the PSU’s maximum load (170W for the HX850). This means that Professional Series HX PSUs will be completely silent when you’re performing less intensive tasks, such as web browsing or chatting in forums. And the thermally-controlled fan spins up gradually above 20% load, so that it still operates quietly during normal use and when gaming. Basic PC power supplies have fans that spin all the time your PC is on – whether you’re pushing your graphics card to the limit or just surfing the web – making them noisier and more intrusive.

Modular Cables for Easy Installation

Professional Series power supplies have a comprehensive modular cable set that allows you to use only the cables you need for your particular set of components. The benefits of this include a cleaner, neater installation, and that ‘professionally-built’ look, plus increased airflow through the case due to reduced cable clutter. The cables are also long enough to support full-tower cases.

80 PLUS Gold: High Efficiency – Low Heat

Efficiency is the measurement of how effectively a power supply converts AC power from your wall outlet to the DC power used by your PC’s components. If your power supply isn’t efficient, it will generate more heat, which requires more cooling and more fan noise. And, it might even affect your power bill.

Professional Series HX PSUs are among the most efficient on the market. Each model has 80 Plus Gold certification, which ensures up to 90% energy-efficiency. This helps to keep your PC cool and quiet, and it may even save you money too.

Reliable

Professional Series HX PSUs are built with premium components, such as 105°C capacitors, and are capable of continuous power delivery at a temperature rating of 50°C, ensuring maximum performance and reliability even in the most demanding and hot-running performance PCs.

The Corsair Advantage

Corsair Professional Series PSUs are backed by a reassuring 7-year warranty and comprehensive customer support via telephone, email, forum and the Tech Support Express helpdesk."
