SolidLink™ Power Supplies
Less Wire, Less HeatSolidLink Full Modular PSUs don't have as many primary wires, instead we use pin lag that directly connect to the connector daughter board.
Traditional Full Modular PSUs tend to have a bundle of cables which are connected to the connector daughter board which generate heat causing Wattage loss.SolidLink™ Technology Difference
- Drastically reduces the lost Wattage
- Draw less wall power which save you money
- Replaces traditional wired connections with direct pin to port connections.
- Reduces heat generated by wires.
- Reduces lost Wattage giving you clean, consistent high quality voltage.
Hybrid Fan Control
Quieter, Saves PowerHybrid mode when activated, allows your fan to stay off when your computer is idle but turns on automatically when the PSU needs it.
- Operates Silently until it reaches 20% load or 77°F (25°C)
- Switches to Quiet Mode (only 16dBA)
- Reaching 50% load which Cooling Mode to cool the PSU appropriately

Not all wattages are the same. Traditional Multi-Rail PSUs might claim to have higher wattages, but they are 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. EasyRail Technology provides true total wattage – when you expect 200W, EasyRail gives you 200W. One Rail, One Setup.
XFX Core Edition Pro Series PSUs are designed to deliver tight DC voltage regulation (±5%) with minimal AC ripple, giving you safer, cleaner power which along with XFX’s new EasyRail Technology allows you to connect numerous devices without worrying about running out of power before reaching the maximum wattage. EasyRail optimizes it all for you. Available in 650W, 750W and 850W, XFX Core Edition Pro Series PSUs with EasyRail Technology give you one continuous rail of power covering the total maximum wattage.
