HX 750 Platinum

Corsair is one of the most popular suppliers of desktop PSUs in the world. It’s no surprise then that they also make some of the best units that are on the market today. Time and time again, we’ve reviewed their PSUs and they’ve walked away with our top awards. With a focus on premium build quality, high-end performance, and competitive prices, Corsair have done great in the past. Of course, with that in mind, we’ll be expecting nothing but the best today. Let’s jump in and take a look at what their new HX 750 80 Plus Platinum Fully Modular PSU has to offer!

Platinum efficiency, fully modular and virtually silent

CORSAIR HX series power supplies give you extremely tight voltage regulation, quiet operation, Platinum-certified efficiency, and a fully modular cable set. Built with all Japanese 105°C capacitors, they’re a great choice for high-performance PCs where reliability is essential.

In the very nicely designed box, you’ll find the PSU and cables each come in their own protective bags. There’s also a good bundle of documentation, cable ties, screws, and a power cable included; everything you’ll likely need.

This is a high-end PSU, so it comes with a fairly amount of modular cables. There’s a good number of SATA and Molex, which are all flat cables. The fatter braided cables offer up plenty of 6+2 and 4+4 connections, as well as the 24-pin motherboard connection.
