Zalman is ready with its newest high-end power supply unit (PSU), the ZM1250 Platinum. It can deliver 1250W of continuous power, and boasts of 80 Plus Platinum efficiency rating (89-93% at 20-100% load). It features full bridge and LLC resonant circuitry, with DC-DC switching between the various voltage domains. It uses a dual +12V rail design, with two dissimilar capacity rails. It is compliant with ATX v2.3, SSI-EPS v2.92, and ErP LOT6.

The PSU is partially modular, when it comes to its cabling. The first +12V can deliver 45A of current; the 24-pin ATX, 8-pin EPS, and the various peripheral power connectors (SATA, Molex, Berg) are connected to this rail. The second +12V rail can deliver 65A, and to it, a total of eight 6+2 pin PCI-Express power connectors are wired, of which two are fixed, and six are modular.The ZM1250 Platinum uses high-grade Japanese-made capacitors, a dual transformer design, APFC, and a protection IC on the secondary stage, which protects against over/under voltage, current, over-temperature, and short-circuit. A temperature-controlled 140 mm fan cools the unit. The 1250W 80 Plus Platinum modular PSU calls for a US $320 price.
