Enermax expanded its Revolution85+ power supply series lineup with new 920W SLI and 1020W SLI variants. These PSUs feature modular cabling, and bear the 80 Plus Silver efficiency rating along with NVIDIA SLI-Ready certification. What sets the 1020W SLI apart from the older 1050W SLI or the 1050W CrossFireX is the redesigned 12V DC circuitry. The 1020W SLI uses four 35A rails compared to five 30A rails on the 1050W SLI/CrossFireX variants, which increases efficiency, and power-delivery per rail to cope with multiple high-end NVIDIA GeForce GTX 400 series graphics cards in SLI. Cables included besides the ATX 24-pin, and 8-pin CPU are: another 4+4-pin CPU power connector (ideal for dual-socket motherboards), two fixed 6+2-pin PCIe power along with four detachable 6+2 pin PCIe power cables, 12 SATA power, 6 Molex, and 1 FDD. Also featured are Active PFC, "SafeGuard" (an umbrella term for OCP, OVP, AC UVP, DC UVP, OPP, OTP, SCP, and SIP power conditioning features), HeatGuard (that cools down the PSU even after shutdown), guaranteed 24/7 @ 50 degrees Celsius uptime, and Silent Ready (temperature-based fan acoustic management). The PSUs are cooled by a 139 mm twister-bearing (long-life) fan. The new Revolution85+ 920W SLI is expected to be priced around the 200 EUR mark, with the 1020W SLI going for around 235 EUR.
