I had intended to write a separate conclusion for each power supply but the XFX Pro Series Core Edition power supplies have performed similarly throughout testing so I don’t think it necessary.
XFX place great importance (throughout the packaging and their literature) on the EasyRail technology used in the Pro Series power supplies. What is EasyRail technology? It’s marketing speak for a single 12V rail and the added benefits of no load balancing and the possibility of locked in or lost power that can sometimes result on multi-12V railed power supplies.
The XFX Pro Series Core Edition power supplies performed very well across the range. The DC voltage load regulation was excellent from 20% to 100% DC loading and in combination with very low AC ripple/noise levels means excellent DC quality on all rails on all three power supplies. The 3V3 and 5V0 rails dipped a little lower than I would have liked but they still remained well within the limits set down by the ATX12V V2.2 specification and won’t prove to be a problem when the biggest dip below ideal rail voltage was only 0.09V. Efficiency levels across the range are acceptable with the PRO850W proving marginally more efficient than the others and efficiencies in the low to middle eighties are on a par with other units in this class.
The only difference across the range is an extra three SATA connectors on the PRO850W so power supply selection at the build stage is important and is really graphic card dependent although any of the three power supplies could power a dual graphics configuration on a fairly standard PC. If the intended build involves powerful graphics cards, multiple hard disk drives, cooling fans, etc and a certain amount of overclocking, the PRO750W or PRO850W would be a more sensible choice.
The XFX Pro series power supplies are, as you’d expect, physically alike across the range and with good build quality and their unique styling will probably appeal to many enthusiasts. If you are in the market for a high quality wired power supply, at a fair price, then I highly recommend any of the XFX Pro Series Core Edition units. I have no hesitation in awarding all three XFX Pro Series Core Edition power supplies the OCC Gold award.
Excellent DC quality
80 Plus Bronze certification
5 year warranty
Plenty of connectors
Fan noise at full load maybe a problem for some?
Just like the 650W model, there is really nothing bad about the performance of the Pro 750W Core Edition. Once again, the only major flaws I can find are in the packaging and the barrage of "single 12V is better" marketing hooey. Look past the annoying packaging, and you find a very well performing, very stable power supply that I wouldn't hesitate to put in any of my computers and run all day long. These are just good units here, people. Go buy one.
more efficient overall than the 650W
extremely stable regulation
better value than the 650W model
could do with a second EPS12V connector
