Corsair HX750i Power Supply Review

Corsair has become known as a quality supplier of quite a few different products over the past few years, one of those being power supplies. Power Supplies have become a big part of their business and their professional HX series has been out for the past few years, being updated every so often. Just recently Corsair updated the line with the HXi series giving the units an 80PLUS Platinum certification, which means the unit will be 89% efficient at 100% load and 92% efficient at 50% load. The HXi series units also feature a fully modular design so you only use the cables that you need, have a Zero RPM mode which means the cooling fan will only spin up during high load and HXi series is Corsair Link ready so you can monitor and log fan speed, voltages, efficiency and more. Will this be the perfect power supply for your next build? Read on as we find out.

Special thanks to Corsair for providing us with the HX750i Power Supply to review.

Packaging
The HX750i comes in Corsair’s typical retail packaging. On the front there is a photo of the unit and it lets us know some of the main features which include a 7 year warranty, zero RPM fan mode, Corsair Link ready, 80PLUS Platinum certification, and ultra low noise design.

Opening the box up inside you will find the HX750i power supply inside a nice protective bag, a bag of modular cables, zip ties, mounting screws, warranty guide, a case sticker and the user’s manual.

    I have an H100i cooler, and I have always had major issues with the Corsair Link software. You say here that it is a great piece of software. What version did you use, and where did you get it?

  • Dan it worked just fine on my system. The version was 2.7.5339 and I downloaded it from Corsair’s website: http://www.corsair.com/en-us/support/downloads

  • Dan Gingerich

    Thanks. I think the last one I had was 2.5, and that had horrible issues with Win8.1.

    I don’t get it (I really don’t); all these company’s are coming out with newer – more efficient and digital to boot – PSU’s, yet still include an ancient floppy drive connector…why?

  • I get what you are saying, although with the power supply other devices do use that connector like fan controllers and hard drive enclosures.

  • Dan Gingerich

    Well, some people still do use floppy drives, as mysterious as that may be. My dad still uses his LS-120 drive.

    As for that Z97-K/CSM, the CSM portion stands for “Corporate Stable Model.” Many corporate workstations still use PCI devices, and their business relies on that PCI device. So, Asus putting out a motherboard that will be around a while (the CSM part) and has PCI slots means those corporations can rely on having the support they need. Back when PCIe first came out, when most mainstream motherboards had one AGP connector and 5 or 6 PCI connectors, and ISA had been gone for more than three years, I knew of a couple corporate systems that still used ISA and EISA cards, and those businesses relied on those systems. A significant portion of their business would be significantly impaired if those systems went down for any reason.

    I remember one system in particular that was hooked to a high speed document scanner through an EISA card to a motherboard with a Pentium III Xeon. This system would scan the documents into a system where the customers service department could call them up to confirm a transaction took place, and the circumstances around it. If that system had gone down for any reason, they would have in excess of 10,000 documents per day stacking up that they needed to store. Eventually, they did add a second system for redundancy, but that one system performed on its own for over three years. It wasn’t smart, but it was what they did. These days, they’ve replaced that with databases and computerized interfaces, but back then it had to take place on paper before it could be computerized.

    psu manufacturers should provide means to run water pump without power on the motherboard, so its possible to fill the tubes without overheating the cpu. also would be nice to provide powering of fans when motherboard has been switched off, but components are still hot. and you should measure voltage ripple amplitude and voltage spikes when powering on and off the psu hard at the back. i know, it takes an osciloscope to read millisecond x millivolt scale. but at least do tell if the psu is noisy (air outtake) and how cool/warm is it at 80% (or more) power draw.
