As you can tell from the cable summary, the ProSeries 1250W unit is fully modular. XFX includes a very comprehensive list of cables and connectors to cover you in just about any situation that you could come across. The only real complaint is that all four of the PCI-E cables are of the same length and this was the same complaint that we had with the 1000W model. XFX was smart enough to take care of this with the SATA and Molex cables as they have several different lengths, but not with the PCI-E cables. A few inches of variance in them would have been nice.
XFX keeps the rail distribution sweet and simple with a single 12V rail. This is the "EasyRail Technology" that they bombard you with on the front. It is just a marketing ploy to make you think it is something new when in reality it is something that we have been enjoying in high end power supplies for quite some time.
A Look Inside
Once we open up the case, we find that it is built just like the 1000W model with the fan being mounted to a plate separate of the bottom of the power supply like we are accustomed to seeing. Once we pull the fan from the unit, we find that the unit looks like it is identical to the ProSeries 1000W.
The same trio of capacitors adorns the primary side of the 1250W ProSeries power supply.
Nippon Chemi-Con capacitors were present on the secondary side as well.
Cooling the 1000W ProSeries power supply is the Protechnic Magic MGA13512YF-O25 135mm fan.
