With the release of the next generation Intel Core processors (codename Haswell), Intel will introduce technologies for reducing power consumption of the CPU in sleep mode. While Ivy Bridge CPUs had a minimum power consumption of 0.5 A in a C6 or C7 state, the Haswell processors would require only as little as 0.05 A. The problem is that a number of older power supplies are unable to deliver such low loads at stable voltages, meaning that the system could crash due to unstable voltages when in C6 or C7 state.
A number of manufacturers are already advertising power supplies that have perfectly stable voltages even down to 0 W, among which is Thermaltake, Enermax, and Seasonic.
The EVGA SuperNOVA 1000 G2 (120-G2-1000-XR) is the newest EVGA power supply. It offers 1,000 W of continuous power, is 80 Plus Gold rated, has a single +12 V rail, Japanese capacitors, a 140 mm double ball bearing fan, a modular cabling system, and the following protections:
OVP (Over Voltage Protection)
UVP (Under Voltage Protection)
OCP (Over Current Protection)
OPP (Over Power Protection)
SCP (Short Circuit Protection)
OTP (Over Temperature Protection)
This brand new unit from EVGA is priced at USD 199.99.
Seasonic’s power supplies listed below are already prepared for the upcoming Intel processors. They are equipped with a DC-to-DC converter which enables the so-called ZERO Load Design. These power supplies will deliver rock-stable voltages even at 0 W load.
Cooler Master has announced the entrance of the V Series Power Supply (PSU) line to North American markets.
Developed to be the highest quality, Cooler Master carefully sourced every aspect of the V Series PSU line to produce a high-efficiency and stable power supply. This operational stability includes being highly efficient even at low loads – far exceeding the parameters of the breadth of operational efficiency exhibited by a typical 80 Plus Gold PSU.
A single, powerful rail platform channels the full power of V Series PSUs with outstanding voltage stability, ripple suppression, and efficiency.
These higher quality components include the highest grade Japanese electrolyte and solid capacitors, a custom PCB interface, and high quality 42 mm transformers.
All of which are among a few of the integral parts that make the V Series a great power supply.
V Series PSUs include a 135 mm Fluid Dynamic Bearing (FDB) fan. This bearing type offers superior performance at lower noises while lasting far longer than the typical PSU fan. The real-world result is that V-series PSUs are extremely quiet, even under full load while still keeping cool.
When considering ease of use and ability to manage cables, fully modular flat ribbon cables are among the best. These give users the ability to compress and arrange their cables in clean and compact ways not possible with traditional and individually sleeved cabling - saving time and enabling builds with the best possible airflow.
It supports 4th Generation Intel Core Desktop Processor C6/C7 Power States allowing the processor to go from C0 (active) to C7 (Deep Power Down Mode) which helps provide maximum power savings.
The V Series will be available in 700 W, 850 W, and 1000 W models. Price and availability may vary based on region. This release is meant for the U.S. and Canada regions only.
Thermal Solutions specialist Gelid Solutions adds cable as a new product category to its GAMER product line.
To start, power supply cable adaptor such as 6-pin (PCI-E), 8-pin (EPS), and 24-pin (EPS) with precisely prepared high-end UV reactive single sleeve in black, white, red, and blue will be offered for the enthusiast. All cables have 18 AWG and a length of 30 cm.
6-Pin Single Sleeve (black, white, red, and blue): USD 6
8-Pin Single Sleeve (black, white, red, and blue): USD 8
24-Pin Single Sleeve (black, white, red, and blue): USD 10
Intel has just released more details about the new Haswell processors. It sets new benchmarks in terms of energy efficiency. The new C6 and C7 states are able to reduce the CPU power consumption to just 0.05 A while previous Ivy Bridge processors draw up to ten times more minimum current.
But the positive progress of the CPU technology is subject to certain restrictions, because only few power supplies will be able to deliver stable voltages at such low loads. End users are therefore groping in the dark with no clues if their own power supply will be compatible with the new energy functions of Intel Haswell CPUs. PSU manufacturers usually do not state the possible minimum load of their products.
Enermax makes a step forward and publishes a PSU compatibility list. All current high-end and mid-range models from Enermax are already prepared for the upcoming Intel processors. They are equipped with a DC-to-DC converter which enables the so-called ZERO Load Design. These power supplies will deliver rock-stable voltages even at 0 W load. Also the owners of older Enermax power supplies can be relieved: The manufacturer applies the ZERO Load Design already in all high-end power supplies since the Revolution85+ series which was launched in 2008.
Nexus has expanded its power supply offering with the launch of the RX-6500 model. This 650 W unit features a modular cabling system, an active PFC circuitry, a single +12V rail, efficiency over 85%, and a 135 mm ball-bearing fan.
This power supply has been treated with a special paint. This paint gives the power supply the appearance of being covered with fibers.
Huntkey has introduced its ES 90W Notebook Adapter – Ultra Edition. Compared to the traditional ES 90W Notebook Adapter, the ultra edition is mainly improved in five aspects:
The conversion efficiency is increased to 89%, 2% higher than ES 90W;
The stand-by power is lower than 0.2 W, whereas the stand-by power of ES 90W is lower than 0.3 W.
The size is reduced by 21.9%, compared to the traditional edition;
Bended tips save space, compared to the straight tips of the initial edition;
The output voltage of 19.5 V allows for applicability to more laptop computers, compared to the output voltage of 19 V adopted by the initial edition, as well as most traditional notebook adapters.
The ES 90W ultra edition is equipped with eight different tips. So if you buy an ES 90W ultra edition, you can use it on almost any brand of laptop.
Nexus has released an updated version of its NX-500 power supply. The improved NX-5000 unit changed its power from 530 W to 550 W and is now compatible with ErP2013 standard, which means the power supply is not using more than 0.5 W at standby mode.
Nexus also used better components to raise the efficiency level to a minimum of 85%.
