Korean company Zalman is on the verge of launching its Goldrock series mid-capacity PSUs. Available in capacities of 550W, 650W, and 750W; the PSUs are 80 Plus Gold compliant, with 87% to 92% efficiency at 20% to 100% load. The Goldrock series PSUs strike a cost-performance sweetspot by providing high-end PSU features, and making up for it with fixed cabling.

The Goldrock series PSUs from Zalman pack high-grade Japanese capacitors, active PFC, LLC resonant circuit, DC-DC switching. A single +12V rail design is implemented, which can deliver 45A of current on the 550W variant, 54A on the 650W, and 62A on the 750W variants. A 5VSB green IC gives the PSU ErP Lot 6 compliance. A secondary protection IC gives it protection against over/under voltage/current, overload, and short-circuit. The 550W, 650W, and 750W variants are expected to be priced at US $134, $145, and $158, respectively.

What happens when you send a PC cooling expert such as Zalman into the field of PSUs? You get PSUs with genuine innovation in cooling, which translates to quieter PSUs. Such is the case of the ZM750-HP Plus, an upper-mid range 750W PSU from Zalman. The PSU replaces aluminum cooling plates with copper heat pipes that draw heat away from hot parts (such as FETs), and onto aluminum fin stacks, which are ventilated by a large 140 mm fan. Since a lot of heat is dissipated passively by these large heatsinks, the fan has very little work to do, and so it spins at low speeds, resulting in very quiet operation.

The ZM750-HP Plus features modular cabling, enough to wire out a gaming PC with two graphics cards. The PSU is 80 Plus Silver-rated. It uses a quad 12V rail design, among which two deliver 28A each (for graphics cards), one delivers 25A (motherboard and SATA), one delivers 20A (CPU, dedicated to the EPS connector). It uses a dual forward-switching design, with active PFC. A secondary protection IC governs various safety features such as OCP, OVP, SCP, UVP, and OTP. The ZM750-HP Plus from Zalman, is expected to be priced at US $189,50.

EVGA is readying a new line of high performance power supply units (PSUs) for gaming PCs and overclocking bench setups, under the NEX Series. The company isn't new to PSUs, as it had rolled out a SuperRecord-branded 1200W PSU in the past. The NEX Series, however, is more spread out, into various price points. At least four models are confirmed, 650W and 750W models for gaming PCs, a 1000W model for overclocked gaming PCs with 2~3 graphics cards, and a bleeding-edge 1500W model for overclocking bench setups.

The EVGA NEX 1500W will include "customizable" +12V rails, we're hearing. It will probably be a mechanism with which a number of smaller 12V rails can be combined to make a larger one. It will feature a "Dummy Mode" for multiple/redundant PSU operations, an "OC Mode" that clubs all 12V rails to a single 133A one, and a very special kind of cabling. The PSU will qualify for 80 Plus Gold certification. The 650W, 750W, and 1000W models in the NEX Series will have more standard feature-sets, including modular cabling, all three of these will be 80 Plus Gold certified.

Platimax continues the row of path-breaking power supplies from Enermax. It is based on the proved, high-performance technologies of predecessor power supply series, the so-called Dynamic Hybrid Transformer (DHT) Topology and Full-Zone Magnetic Quadrant Transformer (FMQ) Design. Enermax engineers successfully improved the cooling performance by applying innovative solutions and equipped the PSU with hand-picked, premium-quality components. That way, Platimax breaks down the barriers of the highest efficiency class, 80 PLUS Platinum.

With 89 to 94 per cent efficiency between 20 and 100 per cent load, Enermax shows the way into the future of power supply. Due to its first-class components, the flexible modular or full-modular cable management and numerous connectors, the new series is designed for long-during and reliable operation. According to that, the manufacturer grants 5 years warranty on all Platimax PSU.

ADATA Technology Co., Ltd., a worldwide leader in high performance memory and flash products, has announced the launch of the HM Series power supply for personal computers. The HM Series has a PF (Power Factor) of 0.9 up and energy efficiency up to 82%, and is designed for the gamer, high-performance, and overclocker markets.

Available in a range of wattages (550, 650, 750, 850 and 1,200 watts), the HM Series delivers reliability and protection for all types of hardware configurations. In particular, the units are equipped with an intelligent dual ball bearing LED fan with a tri-color output power display. The power consumption status is indicated by the color of the display (green for low load; blue for normal load; red for full load). The HM Series is constructed with all Japan-made capacitors for voltage regulation, filtering, and buffering functions, resulting in long-term power output stability, with MTBF (Mean time between failures) of over 100,000 hours. The high ratio of output to input power has earned the HM Series the 80 Plus Bronze certification for energy efficiency.

Be Quiet! (brand name) announced a major expansion of its power supply lineup, with two new product lines: the 80 Plus Silver certified Straight Power E8 series, and 80 Plus Gold certified Dark Power Pro P9 series. The Straight Power E8 series includes 400W, 450W, 500W, 550W, 600W, and 700W models that have completely fixed cabling, and 480W, 580W and 680W models with modular cabling. The Dark Power Pro P9 series, on the other hand, includes 550W, 650W, 750W, 850W, 1000W and 1200W models, all of which have modular cabling.

The Straight Power E8 series models are ATX V2.3 and EPS 12V V2.92 compliant, use a more compact chassis, and are cooled by a 120 mm Silent Wings fan, and use four 12V rail design (with the exception of the 400W model that has a three rail design), prices for this series start at €69.90, and go all the way up to €149.90. The Dark Power Pro P9 uses a slightly longer chassis, also cooled by a 120 mm fan, it uses highly durable capacitors, and a four 12V rail design. These are priced between €149.90 and €269.90.

XFX announced its new, more affordable, high-wattage PSU series, the Pro Series Core Edition. These are non-modular, single 12V rail design PSUs which feature what XFX refers to as "EasyRail" technology, that ensures all components get to draw their required amount of power since a single-rail design is more accommodating compared to a multi-rail design. It is available in 650W, 750W, and 850W models. The company did not detail the connector layout of each model in detail, but we can tell that all models are SLI and CrossFire certified, and going from bottom up, support 2-way and 3-way multi-GPU configurations.

Renowned overclocker Chew* set a speed record for AMD's new value dual-core processor, the Athlon II X2 255. Based on the Regor core, the X2 255 is a monolithic dual-core chip, with just two physical cores on die, and additional L2 cache, with no L3 cache. This cuts the TDP of the chip to 65W. On the bench built by Chew*, the X2 255 reached 4800.1 MHz, with a BClk of 320.01 MHz, multiplied by 15.0. The chip's natural multiplier value is 15.5x, its stock speed is 3.10 GHz. A VCore of 1.696 Volts was set.

The processor was cooled using a Mach 1 phase cooler. The bench consisted of an Athlon II X2 255, Gigabyte GA-MA785GPMT-UD2H motherboard - another mainstream component which proved its mettle, OCZ DDR3 1600 MHz Black Edition certified memory, PC Power & Cooling 1200W PSU, and ATI Radeon HD 4890 graphics. The CPU-Z validation for this feat can be found here. In the same occasion, Chew* could overclock the chip to 4050 MHz using a reference AMD CPU cooler (which comes bundled with higher-end AMD chips). More pictures at the source.

Here are some last minute pictures of the CM 690 II chassis along with the Cooler Master GX line of PSUs and V6 CPU cooler. There has been a lot of buzz around the new case and it lives up to the hype. Upon first inspection, the case does seem to be a valid successor of the original 690. The most obvious and certainly very nice feature is the top SATA port, which allows you to plug in drives without any extra casing or the need to open the chassis up (Ed. note: no the hot girl does not ship with the chassis). Next up we have the GX series of power supplies, which will be available at 650 and 750W soon.

Last, but not least we have the V6 and V6GT CPU coolers. They differ only in the number of supplied fans and look of the top cover. The V6 holds a single fan, with the possibility of adding a second one, while the GT already ships with a pair along with an LED light on top of the cooler, which may be turned on or off. These coolers have a V shaped arrangement of heatpipes so that each of them has direct access to the air flow of the coolers.
