Since introducing the HX520W and HX620W units a few years ago, Corsair's PSU range has been widely praised for its consistent high quality. Launching today is the HX650W, which now becomes the successor of the popular HX620W. Being part of Corsair's "professional" series of power supplies, it offers up flat modular cables, 80 PLUS Bronze certification and a single 12V rail that delivers up to 52A (624W, or 96% of the total power output of the the PSU). It also guaranteed to deliver 100% of its rated power up to an ambient temperature of 50c. With four PCI Express power connectors, it should provide a good option for those looking to run SLI or Crossfire configurations without opting for one of the more monstrously rated units we see available on the market. It slips into the HX range a peg below the HX750W, which when reviewed here at OCC managed to earn an editors choice award. If it can match the performance of its bigger brothers then Corsair should be on to another winner. The HX650W is listed on Newegg now for $139.99.

SilverStone Power Supplies Behind World Record Benchmarks

Author: Dale Shuck

One common recurrent theme here at OCC when people seek out advice on system builds is to make sure your build includes a good quality power supply. SilverStone has long had several units on the OCC Recommended Power Supplies List and Kingpin and Shamino, two world-class overclockers, recently depended on a pair of SilverStone power supplies to help them set new 3DMark world records.

The duo used liquid helium to cool an Intel Xeon W3540 CPU down to around -240°C on their way to achieving a top speed of 5.0969GHz. Also involved were a pair of NVIDIA GeForce GTX 295 videocards all backed by SilverStone OP1200 and Strider ST1500 power supplies to handle the extra power requirements. The newly released Strider ST1500 is a beast itself with eight +12V rails delivering 25A each through all modular cables. The PSU is rated at 1500W continuous power at 40°C and comes with active PFC and an 80 PLUS Silver certification. That means the ST1500 can deliver 85-88% efficiency over a full 20-100% of its rated load.

Not everyone needs that much power, but its pretty impressive that SilverStone can offer that much capacity for enthusiasts and overclockers who need reliable, steady power at high efficiency levels. You can read more about the record setting run here.

Many manufacturers showcase their upcoming products at Computex and among the wave of new products spotted is the SilverStone Strider ST1500 PSU. The ST1500 has an extraordinary power rating of 1500W although it can rise to 1600W under optimal conditions. The Strider is modular and includes four 8 pin PCIe connectors, eight 6 pin PCIe connectors, 12 SATA connectors, a 24 pin and 8 pin motherboard and CPU connector respectively and a handful of molex connectors. Eight 12V rails (25A each) provide plenty of power for hungry systems. It is worthy to note that the Strider has attained the 80PLUS Silver Certification according to SilverStone. One 135mm fan cools the unit, although that seems under-done to me. The ST1500 measures 8.7" x 5.9" x 3.4" or 220mm x 150mm x 86mm (WxHxD). The Strider will retail for around $US450, although I'm not sure who would actually need 1500W of power from an in-case PSU.

Energizer will be unveiling a new battery during CES 2009, which they claim will provide up to three times more runtime than similarly sized alkaline or lithium-ion batteries. Zinc Air Prismatic batteries apparently offer high energy density along with a thin form factor. Those qualities should allow greater flexibility in design for those companies interested in using them, as well as enabling small devices. It all sounds very promising at the moment, but we only have Energizers word to go on. Hopefully we'll get time during CES in January to get a look and see if they really are that impressive.

Cooler Master has been selling its Silent Pro Modular power supplies outside of the U.S. already, but due to patents held by Ultra with regards to modular PSUs it has taken some negotiation to allow the new PSUs to be sold stateside. Models sold elsewhere range from 500W - 700W (you can view them here), though it seems the top end 700W model (with a single 50A rated 12v rail) will be the first to appear through Cooler Master USA. As you may have guessed from the name, Cooler Master are claiming near silence from the 135mm fan cooled unit, along with quality Japanese sourced capacitors and a couple of PCIe connectors that should handle SLI setups comfortably. As is usual with these things, pricing and availability isn't specified.

Panasonic is set to show off a new prototype of its direct methanol fuel cell (DMFC) this week at a show in Japan. Panasonic engineers have succeeded in reducing the size of the fuel cell to about half of the previous version. At 270cc the new cell can deliver up to 20 hours of power on a single 200cc charge of methanol. A simple refill of the unit can bring it back to full power. In addition to the fast recharge time, DMFCs often longer life and are more environmentally friendly than current lithium-ion batteries. Panasonic is also working on a separate DMFC charging station with USB ports to allow users to refresh batteries on other electronic devices such as cell phones and multimedia players. Panasonic has been working on developing fuel-cell technology for the last eight years but has not committed to firm plans to bring the device to market until the end of 2012.

I missed this earlier on in the week, but I think it still warrants attention. It would seem that Enermax has been preparing the succesor to its well received Galaxy series of power supplies, though hasn't been proudly displaying them at Computex, but rather giving sneak peeks behind closed doors. If you remember a week or so ago, we reported on Coolermaster announcing the first high wattage supply to achieve the 80 Plus Silver certification, well it seems that both of these new Enermax supplies (1050W and 850W) also hit this target. To achieve this a power supply must return certain efficiency figures at different load levels: 85% @ 20% load, 88% @ 50% load and 85% @ 100% load. Higher efficiency not only means lower electricity bills but also generally means cooler (and therfore quieter) operation. The Revolution supplies, and their respective test reports can be found among the list of Enermax models on the 80 Plus website. Release dates likely to be late July / early August.

Cooler Master announced it has achieved 80 Plus Silver certification for its UCP 900W power supply, the first ever for a power supply at this power rating. The 80 Plus certification program is designed to encourage power supply manufacturers to design units to achieve an operating efficiency of 80% or greater. Their UCP 900W unit reached this goal and then some by scoring an efficiency rating of 88% at rated loads of 50% which earned it a Silver level certification. Overall, the UCP 900W achieved an average 86.5% efficiency rating. Until now, no other manufacturer has been able to achieve this goal with a power supply of this rating. Certification is awarded at four different levels - Standard(80-82% efficiency), Bronze (82-85% efficiency), Silver (85-90% efficiency) and Gold (>90% efficiency). To put this achievement into perspective, according to the 80 Plus organization, only two other manufacturers have achieved a Silver certificate - Dell with two 255W PSUs and NXP Semiconductors with a 270W unit. No manufacturers have reached the Gold level to date.

Update on the Ultra modular power supply lawsuit

After the recent News Post about the lawsuit Ultra Products filed at the Florida Middle District Court against 22 power supply manufacturers, I received further information about the lawsuit. It is in fact about the US Patent No. 7,133,293, submitted in November 2006 and owned by Ultra Products. There is a long list of the specific models in question by each manufacturer, but I will not bore you with it at this point. The most interesting point about this is the fact that Ultra wants to ban all the 22 power supply manufacturers from any "further infringement of the '293 patent", which suggests that Ultra wants to establish a monopoly in modular power supplies, as well as seeking a little monetary compensation for the 'losses' Ultra had to suffer by the other manufacturers using their patent. We will see how this will unravel.

Corsair is a brand that has been known for memory modules for a long time now, but has successfully entered the power supply market not too long ago. The HX, TX and VX series of power supplies have quickly become known as decent units amongst enthusiasts, but have just now been 80PLUS certified. To get an 80PLUS certification, the power supply unit in questions must be 80% efficient at 20%, 50% and 100% load. The higher efficiency leads to less power consumption, which causes less heat to be generated by the unit, ultimately minimizing the need for loud, high-RPM fans. Most enthusiasts are out for a quiet computer, so that is definitely a plus. Also, lower electricity consumption will keep the wallets of users just as happy as the users themselves.
