SilverStone is on course for releasing the Nightjar ST50NF this Thursday. The ST50NF is a 500W, fan-less (completely silent), 80 Plus Gold compliant, non-modular power supply (PSU). The PSU does away with the 120 mm fan, and replaces it with a large aluminum heatsink that draws heat from numerous smaller heatsinks below that in turn draw heat from the various hot components. To try and offset the weight it puts on with all those heatsinks, and to make the unit airy, the outer body is made of thin perforated aluminum sheets.

The Nightjar ST50NF delivers 500W of continuous power, it is standards-compliant with ATX 12 V2.3 & EPS 12V. It features active PFC (power factor correction), and uses a single +12V rail design. All its cables are fixed to the unit. There should be enough cabling for a performance PC with a single graphics card. The PSU carries an MTBF rating of 50,000 hours. SilverStone's Nightjar ST50NF will be priced at €129.

Enermax announced two new high power PSUs that are compliant with the 80 Plus Gold efficiency rating, under the MaxRevo series. It includes 1350W and 1500W models. The two are designed for gaming PCs with four graphics cards, a ton of hard drives, and possibly even a dual-socket workstation. The MaxRevo PSUs use Copper-Bridge Array transmission technology that is claimed to deliver a 'cleaner' DC output. The 12V circuit is spread across six rails, and is backed by eight kinds of protection circuitry.

The PSU makes use of high magnetic power density transformer, 105°C Japanese electrolytic capacitors, and is cooled by a 139 mm twister-bearing fan that spins between 900 and 2000 RPM. The receptacle features CordGuard, which firmly secures the AC cord, while the fan-controller features HeatGuard, a feature that keeps the fan spinning even after system shutdown, to cool components down. The MaxRevo 1350W is priced at €344.90, and the MaxRevo 1500W goes for €379.90.

OCZ displayed a new Fatal1ty-branded 1000W modular PSU at this year's Computex. The PSU bears 80 Plus Gold efficiency rating, and is fit for gaming PCs with up to three graphics cards, or "hardcore gamers", as the placard puts it. The PSU is partially modular, i.e., essential connectors such as 24-pin ATX and 8-pin EPS are fixed to the unit, while everything else, is detachable. OCZ is said to be using special cables that are flatter and a lot more flexible, to reach around tight spots in the case. The unit is cooled by a 130 mm fan that is red LED-illuminated. It is backed by a 5 year PowerSwap warranty by OCZ.

Thermaltake displayed some of the first PSUs in its new "Smart" series, which is designed to offer "just the right power", in other terms, cost-effective PSUs with proper connectivity. Some of these even feature modular cabling. Thermaltake Smart PSUs come in output capacities below 750W, we spotted a modular 550W model, fixed-cable 630W and 730W models. The Smart M550W is the modular box with 550W continuous power and 650W peak output, it is 80 Plus Bronze efficiency compliant.

The Smart 630W has peak output of 700W, and is designed for entry-level dual-GPU systems (two 6+2 pin PCI-E connectors), it is 80 Plus compliant. Leading the pack is the Smart 730W, with a peak output of 800W, and four 6+2 pin PCI-E connectors. All three models use single 12V rail designs, are standards compliant, and feature most protection mechanisms. Thermaltake is backing these value PSUs with 3 year warranties.

Thermaltake brought out its big guns in the field of PSUs at this year's Computex, with the Toughpower XT GOLD 1475W. As the name suggests, it's 80 Plus Gold efficiency rating compliant. Mind you, 1475W isn't its peak power, but continuous power guaranteed 24x7 @ 50°C. Further, the PSU uses a single massive 12V rail design to deliver that kind of power. The Toughpower XT GOLD 1475W is partially modular, with an angled 24-pin ATX connector and two 8-pin EPS connectors being fixed, and the rest let up for cable management. Thermaltake will back these beasts with 7 year warranty once released.

PSU maker AmacroX displayed Calmer 4, its new silent PSU for mid-range gaming PCs. The PSU is fan-less, and relies on passive convectional air-flow to cool components inside. It can deliver 500W of power, with an efficiency that earns it 80 Plus Gold efficiency rating. The Calmer 4 has fixed cabling, and provides all essential cables, including two PCI-E cables for a single high-end graphics card. It is backed by a 5 year warranty.

In Win's latest case is the Carlian IV, a fancy-looking ATX mid-tower that features a wacky slide-out drive bay design, a space-age white+black color scheme, and plenty of cooling. The company also showed MANA137, an airy new, all-black mid-tower. To top it off, there were 80 Plus Gold Compliant PSUs with 900W and 1200W outputs.

The EZCOOL booth had PSUs of various shell designs, some are fixed-cabled, others semi-modular. One thing common is they're all 80 Plus Gold certified. The run-up began with a compact 1000W fixed-cable PSU, the PS-1000. Next up, are a pair of PSUs with fancy air-intake grills that use acrylic-made designs. Maybe these structures are lit up. The 600W PS-600, and 900W PS-900 fall in this category. Moving on, there's a duo of mid-range, fixed-cable PSUs with fancy air-intakes. The PC-05 is 500W, 80 Plus Gold compliant, and has a gold-colored fan to "show" that. Next, there's the 690W PS-690, another fixed-cable box, but with a round, spirally-spoked grill. Lastly, there's a trio of familiar-looking PSUs, including the 700W PS-07, 650W PS-650, and 890W PS-890.

Strike-X showed off its groovy-looking performance-segment, semi-modular PSUs. Boasting of 80 Plus Silver and 80 Plus Bronze efficiency ratings, the Strike-X PSUs come in 500W, 600W, 800W, and 1100W models. The part that caught our eye was the red+black styling with the "X" cutout design at its air intake. The PSUs are cooled by large 140 mm fans. Essential cables like ATX, EPS, and one set of PCI-E, are fixed, with everything else detachable. Expect these PSUs to be relatively affordable in their segments.

An 80 Plus Platinum-compliant 1450W PSU? No, we're sober. Xigmatek is flexing its engineering muscle in the PSU department with a semi-modular PSU that has both high-power and high-efficiency. The Goliath GP-1451 from Xigmatek gives you all the connectors you'll ever need, and with 1450W, enough power for 4-way SLI, 4-way CrossFireX, dual-socket systems. What's to not to like? The Goliath uses an asymmetric double 12V rail design, the first rail can deliver 55A, and the second 75A. Apart from 24-pin ATX and EPS connectors, most connectors are detachable to improve cable management. The beast is cooled by a 130 mm fan.

If 80 Plus Gold was the order of the best PSUs shown at Computex 2010, this year, the trend is with even higher efficiency ratings, such as 80 Plus Platinum. For any PSU to be certified 80 Plus, it has to go though independent testing, a bad thing if you're rushing in new products. At the same time, having buyers discover that your 80 Plus certifications are fake would be a disaster for your brand. To tide over this dilemma, PSU major Cougar came out with an efficiency rating badge of its own for use on new models, 92% Platinum, denoting that the PSU offers efficiency on-par/close to 80 Plus Platinum. It's probable that these PSUs will get the actual 80 Plus Platinum rating later. Up on display at Cougar's booth were beautiful-looking Cougar PTX 500W and Cougar GX 500W two semi-modular high-efficiency boxes.
