Zalman Unveils 1250W 80 Plus Platinum PSU

Zalman unveiled its newest premium power supply, the ZM1250 Platinum. Its name gives away a big chunk of its chops: 1250W capacity and 80 Plus Platinum efficiency rating conformance. It also features modular cabling, and a large, quiet 140 mm fan. The ZM1250 even has an interesting power-distribution chart.

Korean company Zalman, which specializes in cooling, power, and case-modding products, with ties to the PC enthusiast community that go a long way back, unveiled its latest high-end power supply, the ZM1250 Platinum. The model was made available to select markets outside Korea late last week, and its fact-sheet was scored by Overclockers Ukraine.

The ZM1250 Platinum delivers 1,250W continuous power, its efficiency is backed by the coveted 80 Plus Platinum badge. Up to 93 percent conversion efficiency is guaranteed by its designers, at a load-range that spans across 20 to 100 percent (no "50 percent" rider for maximum efficiency). Other equally important compliances include ATX v2.3, SSI-EPS v2.93, and ErP Lot6 2010. 

The ZM1250 Platinum uses a dual forward switching topology, with a full-bridge and LLC resonance circuit, DC-DC module. It uses a dual asymmetric +12V rail design, with a 45A rail powering the 24 pin ATX, CPU/EPS, which are fixed to the unit, and and a large number of SATA, Molex, and Berg (floppy) connectors through five peripheral power hubs; all of which are modular connectors. The larger 65A rail drives the eight 6+2 pin PCIe power connectors, of which two are fixed, and six modular. 

Our informed guess about the OEM of the ZM1250 Platinum, looking at some of the pictures below, is Channel Well Technology (CWT), certainly a new platform. One can find CWT regulars (for PSUs in this range), such as dual-transformer design, a protection IC governing the secondary stage, APFC and LLC resonant circuitry, and higher efficiency DC-DC switching (for the various voltage domains). The protection IC shields against over/under voltage/current and short-circuit. Another IC handles cooling, care of a large 140 mm temperature-controlled fan. 

Designed for the high-end market segment, the ZM1250 Platninum from Zalman is expected to be priced at US $320 (about S $410).
