XFX Pro Series Core Edition Power Supply Review

XFX is telling us that its new Pro Series Core Edition power supplies are focused on providing high efficiencies and tight voltage regulation. Today we review its 650 watt, 750 watt, and 850 watt PSUs and tell you whether or not this new series of XFX power supply is worth your hard earned money.


XFX is a division of PINE Technology Holdings Limited (along with Samtack) which was founded in 1989 and is headquartered in Hong Kong. The XFX division is a leading AIC partner of NVIDIA based video cards and motherboards as well as AMD video cards. Recently however, XFX has taken to expanding its product portfolio to include AMD based video solutions and now computer power supplies. With PINE's worldwide distribution network, XFX could be poised to become one of the next big brands in the consumer power supply market. Indeed, its initial Black Edition power supplies made a significant splash and XFX is back with a new line of power supplies, the "Pro Series Core Edition.". Today, we are going to be looking at all three current members of the Core Edition series ranging from 650W up to 850W (P1650SNLB9) (P1750SNLB9) (P1850SNLB9) and these units are once more produced in conjunction with Seasonic.

Seasonic is one of the older companies producing consumer power supplies having been founded in 1975 and entering the PC power supply production market in 1980. During that more than 30 years as a company Seasonic has cultivated lines of power supplies that are today some of the standard bearers for efficiency and quiet computing. This focus, and their reputation for quality, has lead to a real explosion in production as Seasonic can be found providing OEM services on various model lines for Antec, Corsair, PC Power and Cooling, XFX, and of course under its own Seasonic brand.

Dig Down a Little Deeper

The Core Edition power supplies from XFX represent its second foray into the power supply realm that we have reviewed, following its successful Black Edition series. In terms of output, the Core Edition power supplies don’t really break any new ground for XFX as they are currently ranging from just 650W to 850W just as the Black Edition units do. However, this output range represents perhaps one of the largest in terms of sales in the enthusiast market so covering it well will certainly help raise XFX's stock in this particular product category. Since the Black Edition and the Core Edition do overlap in output capacity, how is XFX positioning these units such that they differ from the Black Edition units?

EasyRailآ™ PSUs Get Maximum Power

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. EasyRailآ™ Technology provides true total wattage آ– when you expect 200W, EasyRailآ™ gives you 200W. One Rail, One Setup


آ• Tight voltage regulation (آ±5%)

آ• High power efficiency rating

آ• High quality Japanese brand capacitors (105آ°C)

آ• Ultra silent ball bearing fan provides quiet and superior cooling

آ• Supports multiple high-end graphic adapters in NVIDIA SLI or ATI CrossFire

آ• Supports the latest ATX12V and EPS12V standards

Since that bit of copy from the Core Edition webpage doesn’t actually tell us how they are different (really the majority of what we can tell from all of this is that these are fixed cable units) let’s move on and see what we can expect when a user purchases the Core Edition series of power supplies in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
