The Corsair HX1000i is an excellent power supply for any new build, in fact, the 1000 watts of power it provides is likely well beyond what even the most demanding gaming rigs should require. The 80+ Platinum efficiency rating is also a top notch rating, and is what attracted me to this power supply. These efficiency differences can seem small, but can really add up over time, especially if youre leaving the computer running frequently. The power supply is fully modular, making cable management simpler since you dont need to connect the power cables you do not need, and you dont have a big wad of cables coming out of the power supply together. This power supply is fully modular for every connector, including the motherboard and CPU connectors, not just the component connectors. The power supply is very generous with connectors, as is to be expected from a unit with such a high wattage. The 6 PCI express connectors it offers is a good indication that this PSU can handle even multiple graphics card workloads. Its also generous with SATA connectors and traditional molex connectors, it offered many more connections than I needed for my build, and thanks to the modularity, I was able to not plug in the cables I didnt need. The fan only engages when absolutely necessary for cooling the unit, so it can operate silently in a majority of conditions. In my build, it basically hasnt engaged at all. Im not going to be pushing this unit to its limit.

Quiet Great looking cables with integrated cable combs make for easy cable routing and a great atheistic Powerful, no problem delivering the power for all my components at the maximum efficiency (I buy PSU based on the top of the efficiency curve being at the likely high load power consumption as the computer is likely off if not in full use)

The psu looks, feels, and weighs like it's high quality

- Ample power (wanted a good amount of wiggle room over 700W estimated TPD) - Fully modular for easy setup - Build quality seems good


Easy to install, no components missing, nice and quiet on idle loads, comes with zip ties for cable management. Very satisfied with my product

Quiet. Easy to setup.


Claims ATX 3.1 compliance Says PCe 5.1 ready Modular cables No issues

- connectors feel high quality - cannot hear it in operation - on par with a Corsair CX power supply in terms of build quality and noise level - velcro baggie storing spare connectors is cute

plenty of cables to hook up what you need. has a switch on the back to make the fan only turn on when its under load but i have that turned off and i dont hear the fan at all it is also very quiet.

Have only had it for a month but this is the best power supply. It is overkill but dont cheap out on the psu. Everything feels high quality.

1. Quite 2. Powerful 3. Great quality

It works and trusted brand


Super compact PSU (STX) FULLY modular BRAIDED CABLES... THATS RIGHT, BRAIDED CABLES.
