- Japanese capacitors rated for 100 000 hours MTBF
850W ATX 3.0 power supply for servers
This 850 watt unit meets the ATX 3.0 and PCIe 5.0 specifications and includes a native 12VHPWR connector for modern graphics cards. It delivers 80 PLUS Gold efficiency and uses all Japanese electrolytic capacitors for reliable 24/7 operation in server chassis. The fully modular design keeps cabling tidy in dense builds.
12VHPWR connector supports up to 2X power excursion
The single 12+4-pin 12VHPWR cable handles the transient spikes allowed by the PCIe 5.0 standard without adapters. Combined +12V output reaches 846 watts while the minor rails share 110 watts. Active PFC maintains a power factor above 0.9 at full load across the 90 to 264 volt input range.
Check chassis depth and EPS connector count
The power supply measures 140 millimetres deep so verify the case clearance before ordering. Two 8/4-pin EPS connectors are provided for dual-CPU motherboards; boards needing more will require additional cables. Operating temperature is rated 0 to 40 degrees Celsius with a 120mm FDB fan rated at 18 dBA minimum.

商品問答
Should I pick the 850 W model or a different capacity for a dual-GPU build?
This unit delivers 850 W total with 846 W on the +12 V rail, two EPS connectors and four 8/6-pin PCIe plugs plus one 12VHPWR connector, so it fits dual-GPU systems that stay within those limits.
What does the 850 W rating mean when the PSU is inside a hot server chassis?
The 850 W rating is guaranteed for continuous 24/7 operation at up to 40 °C ambient, with 87–89 % typical efficiency and 80 PLUS Gold certification.
How does the ATX 3.0 and PCIe 5.0 12VHPWR connector affect real-world power delivery?
The native 12VHPWR plug supports the PCIe 5.0 2× power excursion spec, letting a compatible GPU draw brief spikes up to twice its base power without an adapter.
