The Corsair HX750 retails for around $150 in the US while in the UK market is sold for £159.95 including VAT from Overclockers UK.
This is definitely not a bargain 750W unit, however it has high overall performance with very good transient response, which is what matters the most in real life conditions. On top of that it is supported by a hefty ten-year warranty.
Compared to the popular RM750x 2018 edition, the HX750 is equipped with more SATA connectors, but on the other hand it has less 4-pin Molex ones. Both models have the same number of EPS and PCIe connectors (please do note that the previous RM750x only had one EPS). Another difference between those two units is the cooling fan: the HX750 uses a fluid dynamic bearing fan while in the RM750x a rifle bearing one is incorporated.
If you can afford it and you want one of the best 750W units, then the HX750 is a solid choice. However there are more affordable options if you don't want to spend so much including the RM750x, and the Seasonic Focus Gold and Platinum Plus models. All afore mentioned PSUs besides much more affordable also have compact dimensions, which will definitely make the installation process easier. 
With the only exception being the not top-notch load regulation, the HX750 offers exceptional performance, however it carries a high price tag and from the moment someone can get the similar capacity Seasonic Focus Plus Platinum, featuring an even more silent operation, higher performance and smaller dimensions, it is probably high time for Corsair to upgrade the HX family. Meanwhile, a generous price cut would surely encourage more users to include this product into their buy lists.
In the UK you can buy the Corsair HX750 from Overclockers UK for £159.95 inc VAT HERE.

KitGuru says: A high performance quality power supply facing stiff competition in 2018. Corsair should lower the price, get rid of the bulky cables and provide an option to deactivate the semi-passive operation – which is not ideal if you plan to install the PSU with the fan facing downwards.
