Traditional Multi-Rail PSUs might claim to have higher wattages, but it’s achieved by combining multiple smaller, lower wattage rails. Each smaller rail isn’t capable of running multiple high-power devices (GPUs, CPUs) because the individual wattage caps are simply too low. Designed specifically for the performance and value-conscious gamer, the XFX Core Edition PRO850W power supply boasts EasyRail Technology to provides true total wattage to the latest multi-core CPUs and multiple high-end graphics cards. When you expect 200W, EasyRail gives you 200W. One Rail, One Setup.

Supporting the latest ATX12V and EPS12V standards, it is also NVIDIA SLI certified for reliable multi-GPU PC setups. High quality Japanese brand capacitors (105°C) ensure high reliability and long life. 80 Plus Bronze certified, this PSU brings you an exceptional efficiency at up to 85%. Giving more than just life to your PC, the XFX Core Edition PRO850W power supply also features an ultra silent ball bearing fan for quiet and superior cooling, tight voltage regulation (±5%) and fully sleeved cables.

1 out of 5 eggsDead in less than 2 months

Pros: Everything connected well, hooked up good, fit in my Antec twelve hundred easily.

Cons: The darn thing crapped out in less than 2 months. Now time to fight with manufacturer and try and get a replacement. I want my rig to run so I bought a Corsair (which I should of done in the first place) and I'll just use this for a future build if I get a RMA from XFX.

Other Thoughts: Just sucks that it crapped out.
