With its 4th Generation Intel Core processors AKA "Haswell," Intel has introduced a new power saving feature that reduces consumption while the CPU sleeps. This new deep state sleep mode is called "C7" and is causing a lot of tech insiders to second guess if older power supplies will be able to function properly with Haswell.
This morning Fractal Design released a list of their PSUs that are Haswell friendly. With 12 models throughout its Newton R3, Tesla R2, Integra R2 PSU lines on the list, Fractal says that its customers can rest easily knowing that their PSU is compatible with the next generation of Intel processors.
The issues come from the new deepest sleep state, called C7, will be able to reduce the power consumption of the CPU to only 0.05A (0.6W). As this occurs in the deep sleep state, when most other 12V devices are either in low-power states or turned off, this can reduce the 12V load on the power supply significantly.
This morning high-end PC chassis manufacturer Fractal Design unveiled its newest chassis, the Node 304 in white. This sleek, and modular PC chassis continues to adhere to Fractal's "simplistic" design by keeping external features to a minimum.
The Node 304 features accommodations for up to six hard drives, comes equipped with three hydraulic bearing fans, and easy to clean filters on all the air intakes. The front of the chassis bears minimalist design cues with the dual USB 3.0 ports and audio jacks being placed on the right side of the case.
Also featured is a fan controller that is capable of adjusting fan speeds on all chassis fans. This makes the Node 304 the perfect solution for those in need of a refined HTPC chassis, or simply want a uniquely minimalist desktop PC. The Node 304 is capable of fitting Mini-ITX and DTX motherboards with the white version being available in July for about $90.
Corsair has posted up a new blog post that discusses power supply compatibility with Intel's upcoming Haswell microarchitecture. The general gist of the blog post is that most of Corsair's power supplies are compatible, but it also delves into why certain power supplies might not be compatible.
For those readers who are interested, the list above is all of Corsair's compatible power supplies. As you can see, a large portion of Corsair's power supplies are compatible. But why is this important? Haswell's C7 sleep state drops power consumption by so much--down to as little as 0.05a--that some power supplies aren't compatible.
This morning BitFenix announced not one, but two new chassis in their popular Prodigy case line. The two new cases are windowed versions of the company's Prodigy series and come in two new colors - Vivid Green and Cobalt Blue.
The Prodigy green and Prodigy blue both feature a SoftTouch finish that BitFenix is known for, and strong FyberFlex handles for easy portability. Unlike the four colors that came before it, the two new cases also feature a side panel window to enable users to show off their sick Mini-ITX setups.
The Prodigy chassis line has become famous for its spacious interiors, which is something we rarely see in Mini-ITX cases. There is even enough room in front of the drive cage to house a slim line 240mm radiator or you can remove the BitFenix FlexCage and fit much thicker 240mm radiators. Users will also find plenty of room for storage, with space for up to five 3.5-inch drives or 2.5" SSD's. The Prodigy is also capable of fitting video cards up to 320mm in length.
Last week the team over at NZXT released a microsite that teased of the upcoming arrival of a new PC chassis. Many, including myself, speculated that the new case would in fact be the NZXT H3, and we were right, but wrong at the same time. This morning NZXT announced the launch of the H630 silent PC chassis, the next generation in the H series of quiet PC cases.
The H630 is engineered to offer comprehensive liquid cooling support in a clean and silent package, the new H is capable of supporting 360mm radiators in both the top and front positions without any modifications. In addition, the H630 allows for maximum airflow without the removal of sound dampening material.
Alongside the launch of NZXT's H630, the company is also launching a completely redesigned website which will better showcase NZXT's products. The H630 will be available at major hardware retailers in the coming weeks for $149.99 and comes skinned in either white or black.
Enermax has confirmed that their power supplies have been tested and are ready for Intel's upcoming Haswell-based CPU. Some power supplies will be incompatible with Intel's new C6 and C7 power states, which are capable of reducing idle power draw to just 0.05 amps, an impressive feat for Intel.
Enermax says that all current high-end and mid-range models are compatible with the new C states. In fact, all high-end power supplies manufactured by Enermax since the Revolution85+ in 2008 are compatible with the so-called ZERO Load Design, meaning you won't have to upgrade. To make sure your PSU is compatible, check it against the list Enermax has published.
This morning Noctua released a new PWM version of its award winning NF-A14 140mm fan. The NF-A14 was originally released in 2012 alongside its round frame brother, the A15. Both of the fans took the custom PC community by storm with their revolutionary features, such as built-in sound dampening pads, and Advanced Acoustic Optimization features.
The new NF-A14 PWM fan is ideal for those who want automatic fan speed control through the use of PWM headers on the motherboard, or those who use aftermarket or completely custom fan controllers. Sporting a six year warranty, Noctua takes great pride in their integrated PWM electronics and reference class SSO2 bearings.
Roland Mossig, CEO of Noctua, had the following to say:
"Our NF-A15 and NF-A14 fans have been very well received by customers and hardware journalists alike, but we got many requests for a square frame PWM version for use as a case fan and on watercooling radiators. We can now meet this demand with the new NF-A14 PWM."
NZXT has a long history with silent PC cases. Late last night the crew at NZXT released a teaser page on its website that simply showed off a tight crop of a corner of a case, as well as a front I/O panel.
The webpage, titled simply "SHHH...", includes a countdown timer that alludes to an announcement or release of some sorts five days from now. I tried probing my contacts at NZXT, which included the company founder, and was unable to squeeze any more information out of them.
I really do hope that this is a new silent PC design as I own every silent design NZXT has released over the years. In fact, the very first PC case I ever reviewed was an NZXT Whisper way back in the day, and is the chassis that houses my home server at the moment.
Today Cooler Master announced the arrival of two new mid-tower PC chassis branded as the N series. This new series was designed with cooling performance in mind, most notably liquid cooling.
Sporting a sleek, compact design both cases can support up to a 240mm radiator, a full mesh front panel, and a good number of vents, strategically positioned on the case to improve airflow. The N300 has room for up to eight fans, 320mm long video cards, and eight hard drives with room for an additional SSD.
The N500 is capable of supporting up to nine fans total, video cards over 400mm long, and a dedicated SSD cage capable of housing three SSDs total. This comes in addition to the HDD and ODD bays. Both cases are available with or without side panel windows and feature USB 3.0 front ports.
Intel's fourth-generation Core processors are nearly here, otherwise known as Haswell. These processors feature C6/C7 low-power states, and are able to shift gears into a much more power efficient form of sleep.
Well, it looks like most power supplies aren't compatible with this new method, as they aren't able to deliver less than 0.05 amps across the 12V2 rail. The news comes from VR-Zone and has been backed up by The Tech Report, with some words from Corsair's Robert Pearce. Older power supplies, or cheaper models, won't get anywhere near the required low-power that the Haswell processors require, meaning that some systems will experience stability problems, or worse.
The problem worsens, as most power supply makers don't state their PSUs 12V2 rail specifications, making it hard for users to find out whether their PSU is capable of the low-power state or not. Corsair's Robert Pearce has said that he expects most motherboard vendors to disable C6/C7 by default in the BIOS as there are too many PSUs on the market that don't support the C6/C7 low-power state. Pearce said that Corsair is working on making sure that all of their PSU units are C6/C7 compliant.
