OCZ's newest power supplies are 80 Plus Gold certified.
OCZ on Monday announced that it has added 750W and 850W power supply models to its Silencer Mk III Series under the company's PC Power & Cooling brand. There are now half a dozen models to choose from in the Silencer Mk III Series, including 400W, 500W, 600W, 750W, 850W, and 1200W, all of which feature some form of 80 Plus certification (from Bronze on up to Platinum, depending on the specific model).
Corsair, a company best known for its range of memory products, has also built a reputation for high quality power supplies, namely the TX and HX series released a couple of years ago. On paper, Corsair's newly introduced Professional Series Gold units are even better.
The new line features a fully modular low-profile cable set and come rated at 750W (AX750), 850W (AX850), and 1200W (AX1200W). As the naming scheme suggests, these are all 80 Plus Gold certified, meaning they deliver over 90 percent efficiency at 50 percent load.
No easy task, Corsair said it incorporated a number of "sophisticated server-level technologies" to reach 80 Plus Gold status, including Zero Voltage Switching and Zero Current Switching tecnology to eliminate switching losses and reduce EMI, as well as individual DC-to-DC voltage regulation for the 3.3V, 5V, and 12V rails. In addition, Corsair claims its secondary-side synchronous rectification and 4-layer PCB design results in low levels of ripple and noise.
All three power supplies come with a single 20/24-pin ATX connector, two 8-pin CPU connectors, and a single floppy connector. The AX750 adds two 6+2-pin PCI-E, 12 SATA, and eight 4-pin connectors, while the AX850 ups the ante to four 6+2 pin connectors. The flagship AX1200 features six 6+2-pin, 16 SATA, and 12 4-pin connectors.
Each PSU also boasts a single +12V rail with 62A (744W), 70A (840W), and 100.4A (1204.8W) available on the AX750, AX850, and AX1200, respectively.
OCZ has been so busy pumping out SSDs as of late, it's easy to forget the company also churns out power supplies. OCZ hasn't forgotten, and coming soon, the company will add to its PSU lineup with a new Fatal1ty 750W unit.
Currently being shown at the CeBIT exhibition, the Fatal1ty sports an all new modular design fitted with low-profile modular cables. It also boasts a single +12V rail, a staple of PC Power & Cooling units, now a subsidiary of OCZ.
Other features include all Japanese made solid-state primary capacitors, a double ball bearing 135mm red LED fan, and 80+ Bronze certification with 85 percent efficiency.
