Modular Unit with plenty of good quality cables.

Easy to install setup and use. Works great. Simple yet uncomplicated.

Own multiple original SF750s and they have been the most amazing PSUs I ever used in SFF builds. With the ceiling constantly being raised on power draw for GPU's, 850-1000W are like slowly becoming the standard. As unfortunate as that is, if you're going to pick a PSU up that can deliver, then the SF850/SF1000 are the kings in that arena if you build a lot in ITX/SFF, Micro ATX builds. Sorry, but nothing else comes close in terms of sheer reliability, noise, thermal profiles, and quality.

Insane Deal!

Comes with all the cables that you need Fan knob on the back for user control Easy to understand where cables go

Its 80+ platinum, lots of powe, It has all connections fully modular, corsair control on psu

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.

Plenty of power Ease of installation Quiet under load Decent hold-up times

Awesome product and shipping really have no complaints. Runs silent in my new rig.

Very quiet, fan moves lots of air, does it's job power wise, the PS and the wires and connectors are all black which looks good inside my black case.

Installed this in my NZXT H9 case and it was very simple.
