To take a look at the 750w model, naturally we agreed. Being released at the same time as the HX850w an educated guess would tell us that both PSU’s are more or less identical probably barring some slightly uprated components in the 850w version. With this in mind we’re going to be skipping past a lot of the usual waffle regarding the packaging and appearance of the HX750w and concentrating more on the performance of the unit and any differences that present themselves along the way. Of course, if you haven’t yet already checked out our full and extremely detailed review of the HX850w, now is the time to do so! Well the corsair is more in the majority choice for people buying a new rig and pretty recommended by friends or other external influences, even the review right here, that the premium brands to have are one which is the corsair brand of their constant quality in bringing any light to a rig of a professional.
However one easily overlooked difference between the two is the number of hard-wired connectors on the unit. Whereas the HX850w has 2x PCI-E connectors along with the usual ATX and EPS12v connectors, the HX750w is void of any hard-wired PCI-E connectors. This brings the total number of hard-wired connectors down to 4 for the HX750w which is probably about right given the rated power output of the unit.
To cut a long story short, the HX750w is every bit as good as it’s bigger brother the HX850w. Throughout the testing the voltage and efficiency results were so uncannily similar that if not for the MAX load results topping out at 913w (vs 1084w on the HX850w), we would have happily put money on the HX750w simply being a HX850w with different stickers and less two of the hard-wired PCI-E connectors.
In effect, this positions the HX750w as THE BEST 750w PSU. For an extremely reasonable $168US you get a 750w PSU that not only looks awesome with its smooth powder coated finish and flat modular cables, but also performs among the best in its class. Efficiency levels rarely went below 90% even when running well above its rated output, and voltages refused to budge by any noteworthy amount no matter what kind of load we threw at it.
So, for the moment at least the choice is simple. If you’re looking to power a tri-sli system and need a full six PCI-E connectors, then the HX850w is the way to go. However, if you’re sitting on a small roll of $35US notes and are looking for an awesome PSU to power your single or dual GPU system, then you really should be looking no further than the HX750w.
