If you are looking for a power supply in this wattage range the HX1200i is one of the best out there. The biggest thing that you want to look at when it comes to power supplies is voltage regulation and from our testing all of the rails were extremely solid, some of the best we have seen. On top of that the power delivery is going to be efficient as well. This unit is 80PLUS Platinum certified which means that it is 92% efficient at 50% load and 89% efficient at 100% load.
On top of being extremely stable the HX1200i is made with quality components. You can tell by just picking up the unit that it’s made well. Inside you will find Japanese-made 105°C capacitors, which means this unit is going to be extremely reliable. On top of the reliable components Corsair backs this power supply with a 7 year warranty. Typically we see 5 year warranties on power supplies, so having a 7 year warranty should put you at ease.
The 140mm cooling fan on this unit is a Zero RPM fan, which means that the fan will only spin up when the unit reaches a certain thermal load. This not only saves power, but it keeps things quieter too. Being part of the HXi series this unit is compatible with Corsair’s Link software which allows you to view and monitor efficiency, voltages, temperatures, fan speed, and even switch between multi-rail mode and single-rail mode.
The unit is 100% modular so you only use the cables that you need, which makes for less cable mess inside your system. Also the modular cables have a flat design, which makes them easy to work with.
I tried to find something wrong with this unit, but really it is flawless. Corsair has done everything right with this unit, great features, great performance, and one of the best warranties out there. Right now you can pick up the HX1200i at my favorite online retailer for around $282.
