Today we are looking at the new flagship power supply from XFX – the new Pro 1250W Black Edition. This power supply is aimed at the highest level of enthusiast user who might be using a high end SLI or CrossfireX system. It ships with 80 Plus Gold Certification, is a full modular design and has a Hybrid Fan Control system for ultimate noise reduction.
XFX have had a strong relationship with Seasonic in 2011, having released many power supplies which have claimed our highest awards. Seasonic have a well earned reputation for producing high quality designs, so the partnership makes sense for XFX.
XFX are keen to focus on their trademarked ‘EasyRail' technology which they claim “enables you to maximize available power and make set-up easy. Stack numerous power-hungry components, such as your GPU, CPU and other components, without fear of crashing. It’s also a perfect solution for hardcore gamers. One Rail, One Setup”.
Hybrid Fan Control is an interesting new feature. When Hybrid mode is enabled the power supply will operate silently until it reaches 20% load, or 25c. Corsair have incorporated a similar system with some of their high end units, keeping noise to a minimum.
After 20% load (or internal temperatures of 25c) the fan will ramp up, pre-configured to ‘quiet' mode (rated at 16dBa). When 50% load is reached (625w) then the power supply will switch to ‘Cooling mode' which is only rated at ‘greater than' 16 dBa. We will look at this in detail, later in the review.
Another XFX trademark is the new ‘Solidlink' Technology which is said to maximise efficiency. Basically the new design minimises the wiring inside the unit – which subsequently is said to improve heat generation and overall product efficiency.
