Outdated Product
An advanced computer power supply with high energy distribution rates (90% efficiency), 80+ Gold quality certificate and a stylish snow-white case, which is ideal for the popular white computer assemblies. It is a modern version of the original Zalman TeraMax PSU with an updated design and support for all the latest power standards. It is positioned by the manufacturer as an advanced solution for powering powerful gaming PCs, sharpened for high graphics settings and 2K/4K resolution. In terms of power reserve, this 850-watt one will be the best option for near-top-end assemblies with a modern Intel Core/AMD Ryzen 7-series processor and a NVIDIA GeForce RTX 4070/4080-level video card. But for powering a conditional RTX 4090, the flagship modification of the Zalman TeraMax II at 1100-1200 W...is more suitable. Compared to the first version of Zalman TeraMax, the second generation ZM850-TMX2 is equipped with a 16-pin 12VHPWR connector for powering video cards with support for the PCI-E 5.0 bus and the ATX 3.0 power standard. Previously, this would require an additional adapter. As is customary among high-end power supplies, the circuitry of the device is built using reliable high-temperature Japanese capacitors, active PFC, EMI filters and DC-DC converters. This approach ensures high efficiency of energy distribution with a low pulsation level and the ability to briefly exceed peak power, as well as high reliability of the device (there is support for OVP, SCP, OPP, OTP, OCP and UVP).
