Introduction

Earlier this month we took a look at the new 1000W ProSeries power supply from XFX. The new unit sported lots of power, Platinum efficiency and a ton of connectors, but it came at a hefty price. XFX also added a few more power supplies to their lineup and today we are going to be taking a look at the highest wattage unit that they offer.

This is the 1250W ProSeries power supply. It doesn't offer Platinum efficiency, but it offers the same set of features and an extra set of PCI-E connectors with very little additional cost and a mild drop in efficiency. Keep reading on to find out how well the ProSeries 1250W performs and if it is worth your hard earned money.

Specifications, Availability and Pricing

XFX kept the single 12V rail on the ProSeries 1250W power supply and upped the amperage to 104A of power. That is quite a lot of power to be pushing through a single rail, but it has been many times without issue. Both the 3.3V and 5V rails are rated for 25A each with a combined max output of 150W. We feel this is a tad on the low side for a 1250W power supply. It would be nicer to see the minor rails rated for about 30A each with a combined total output of 175W or more.

XFX's ProSeries 1250W power supply has nearly a full set of features and almost gets a green check across the board. All of the protections are there, including the Over Temperature Protection. The unit has an 80Plus Gold certification but isn't rated for 100% continuous output at 50C. This should be a must in a power supply of this caliber as it is almost certainly going to be put under extreme loads for extended periods of time. All of the cables are modular and fully sleeved on the unit.

We were able to find the new ProSeries 1250W power supply readily available at a very wide variety of places and the power supply has an MSRP of $269.99. We couldn't find anyone that could beat Newegg's price on the unit, coming in at $269.99 with free shipping. XFX backs the ProSeries 1250W with a five year warranty.
