Enermax is expanding its Modu87+ power supply (PSU) series with new 800W and 900W models. As the name suggests, Modu87+ PSUs feature modular cabling, and have over 87% efficiency at any given load. The 800W model will be released first, followed by the 900W model at a slightly later date. Both models boast of DHT (Dynamic Hybrid Transformer) technology, an array of solid-state (conductive-polymer) capacitors paired with Japanese electrolytic capacitors, dubbed "Hybrid Capacitor Array", which contribute to rated efficiency up to 92%, which stays over 87% at any load, earning it the coveted 80 Plus Gold rating.

Both models use four independent +12V rails, and are cooled by a 140 mm twister-bearing fan that keeps up with the "gold" theme. Cable modularity covers the 6 PCI-Express power cables, and a number of SATA power, 4-pin Molex, and 4-pin Floppy connectors, with the 24-pin ATX and CPU-power connector being sleeved and fixed. The Enermax Modu87+ 800W PSU will be priced at 174€, and backed by a 5-year warranty. The pricing of the 900W model will be known later.

Corsair's recently announced HX750W and HX850W modular power supply units have bagged the elusive 80 Plus Gold efficiency rating, a title enjoyed only by a few high-end enterprise-grade PSUs. To qualify for this rating, a PSU must provide an output efficiency of at least 87% at 20% load, 90% at 50% load, and 87% at 100% load. At these levels of load, the efficiency of HX750W was measured 88.04%, 90.02%, and 87.04% respectively, while those of the HX850W were 89.14%, 90.38%, and 87.06%. These are Corsair's first PSUs to get the 80 Plus Gold rating, above the 80 Plus Silver which were expected of them, when the two were announced.

Cooler Master proudly announces the 80 Plus Gold Certified high wattage power supply, the highest rated 80 Plus power supply to-date by achieving a typical efficiency of 90.05% .

Cooler Master has long built a strong reputation based on industry-leading designs in coolers and computer cases, while its power supplies have often been over-shadowed. Today, marks a new era in the company's foray into the market of power supplies. With the UCP reaching new 80 Plus Gold specifications, Cooler Master has put itself at the cutting edge of PSU design.

Details of the 80 Plus Gold qualifying certification can be viewed here.

Korean PC cooling specialist Zalman launched the ZM500-RS 500 W mainstream PSU. The PSU provides connectors most common to PSUs in its range, offering support for basic SLI or CrossFire setups, or powerful single graphics cards. Under its hood is the Resonant Switching Circuit Design (RSCD), which Zalman claims to be more efficient than dual-forward switching designs, in minimizing energy loss and heat output.

The PSU uses two 18 A +12V rails and Active PFC support. It has a rated efficiency of 87% and qualifies for the 80 Plus rating. On the connections front, apart from the 24-pin ATX and 8-pin CPU connectors, it provides four SATA, four Molex, one floppy, one PCI-Express 6+2 pin, and one PCI-Express 6-pin connectors. The unit is cooled by a silent 120 mm fan. Following the launch, the PSU should reach markets shortly.

SilverStone is going for the (over)kill with a 1500W enthusiast-grade PC power supply. The Strider Series 1500W (model: SST-ST1500) is one of the first 1000+ Watt PSUs to carry the 80 Plus Silver efficiency rating. This PSU made for an early-sighting at this year's CeBIT event, and is gearing up for launch very soon. It delivers 1500W of continuous, and 1600W of peak power. It features a 100% modular cable design, meaning that even the 24-pin ATX and EPS cables are modular unlike in most modular PSUs.

The unit measures 150 x 86 x 220 mm (WxHxD). Under the hood are eight +12V rails, that belt out up to 120A of current. Active PFC is available. The ATI CrossFireX and NVIDIA SLI certified PSU features four 6+2 pin, and eight 6-pin PCI-Express power connectors. High-grade Japanese capacitors are used. A 135 mm fan with a minimum noise-output of 19 dBA keeps this beast cool. Applications? Plenty: an enthusiast could run a highly-tweaked multi-GPU PC, and be able to directly power one or two thermo-electric coolers.

Memory specialist turned PSU specialist Corsair, has a new PSU up its sleeves. The Corsair HX750W modular PSU is an attempt by the company to fill the gap between the HX620W and the high-end HX1000W, in its HX series, a large one to begin with. There is a definite need for such a PSU since it ups the count of PCI-Express power cables from the PSU, over the relatively paltry two that HX620W offers. Cable modularity is enhanced with the flat-cables the company has been using. With the "750W" marking, we are to assume that is the continuous power rating, as with every other Corsair PSU. The model may fall in league with other ones by the manufacturer to come with a 5-year warranty. It is also indicated that the PSU will come with an 80 Plus efficiency rating. This PSU comes after the company's recent launch of the HX450W.

OCZ Technology Group, Inc., a worldwide leader in innovative, ultra-high performance and high reliability memory and PC components, is pleased to announce that their Z-Series line of PSUs have been certified at the highest efficiency levels by 80 Plus, making the power supplies an exceptional choice for power users demanding the ultimate in performance and efficiency. As one of the first consumer PSUs to meet the strict requirements of the 80 Plus Gold 90% efficiency standard, the Z1000 is now in production and is slated to be the first 1KW power supply available to end-users with the prestigious 80 Plus Gold rating. In addition to the 1000W configuration, two Silver 80 Plus rated power supplies are included in the series-the Z550 and Z650.
