Pros: The package and presentation is great! A nice sturdy box within the decorative outer box contains a large bag full of power cables, a real, thick, multi-language manual, and soft foam that immobilizes the PSU, which comes wrapped in a satin bag. The little touches make this power supply stand out – The chamfered edges, the sturdy connectors that click smoothly and softly into the PSU, the oversized power switch on the back, and the tag that reminds you that it’s perfectly normal for…

Pros: Corsair really knows how to package a power supply. The power supply itself is encased in a felt bag while the modular power cables are kept in a separate Velcro bag reminiscent of a small battery drill bag. This came in handy to store the modular cables not used during the installation. Included in the box is even a baggy of zip ties. The HX1000i is a very quiet unit. The units fan doesn’t kick on till a little over 400 watts (the manual indicates 400 but during testing, this varied)….

Pros: Corsair was originally known for their outstanding PC memory, but about 6 years ago, they made a big splash in the PSU market. Their HX line caught the industry by storm a few years ago and they’re back at it now with their improved “I” series of super efficient, high performance power supplies. I am not going to try to give a professional review of this PSU with voltage and rail readings, because I simply do not have the requisite knowledge and equipment to provide this level of…

Pros: This Corsair unit is packaged exceptionally well in a large box. It is fully modular and it comes with an extended 7 year warranty. The black colored unit with Blue and white lettering looks good too! I have been using Corsair PSUs for the past 7 years. I have the Corsair 1200W and 1000W units powering my bench setup for the past few years and they perform flawlessly. I would have loved to match this PSU up with some enthusiast VGUs but currently I had none available. Therefore my…

Pros: Build: The overall build quality of this unit is very good. It’s heavy and ridged with a very solid fan grill. The plugs are all very sturdy. Fan: The fan is extremely quiet. Granted, in my system the only time it would spin was at bootup. It will only turn on when operating temps reach 40C. Even running a torture test with AIDA64 and OCCT it did not cause the fan to spin. It was only warm to the touch. (see specs below) I was not able to cause any game played to pull enough power to…

Pros: • Tight voltage regulation. • Fan doesn’t kick on until you use more than 400 watts, approximately, and when it does turn on, it’s about as quiet as any other PSU fan of today. Quieter than other fans in the system. • Switch for Single or Multi Rails. • Platinum rated efficiency. 1000 Watts is also a sweet spot if you care about efficiency. Idling you’ll remain above 84%, on average, and at any load above that you’ll easily be in the 90-95% range. • Quality cables. • Corsair continues…

Pros: * Plenty of connectors. Some online spec listings for this PSU are incorrect. It actually has 4 SATA Cables, each with 4 SATA Power connectors, for a total of 16 connectors. It also includes two 4+4 pin CPU power cables, and 4 6+2 PCI-E power connectors. There should be plenty of cables available, however if you plan on running TWO OR MORE HIGH-END video cards each with 3 power connectors, you will not have enough. This is the most cables I have ever seen on a 750W unit. * Cables are…

Pros: I have been a proponent of fully modular power supplies before corsair entered the PSU market. This is a great example of having complete control over cable management. The fully modular feature is worth any added cost. I was intrigued by the selectable 12v multi vs single raid feature. It makes sense if you’re going to try to run one large video card and potentially could be more efficient in multi rail configuration if running lower specs. In addition it has platinum rating, is…
