Description

Digitally Controlled Power The fully modular Corsair AX1200i uses a Digital Signal Processor (DSP) for tighter voltage regulation, which improves overall system stability, and increases performance to 80 PLUS Platinum levels. Built-in Corsair Link gives you unprecedented monitoring and control. Quiet, Efficient Operation Upgrading to digital provides increased efficiency. The AX1200i is certified 80 PLUS Platinum, which results in lower heat generation and a quieter fan profile. The AX1200i is so efficient that the 140mm fan doesn't even spin at low loads for completely noiseless power delivery. Customer Service / Tech support: opt. 1 From the Manufacturer The fully modular cabling system allows you to use only the cables you need. The revolutionary AX1200i is the first desktop PC power supply to use digital (DSP) control and Corsair Link to bring you an unprecedented level of monitoring and performance customization. The DSP in the AX1200i makes on-the-fly adjustments for incredibly tight voltage regulation, 80 PLUS Platinum Efficiency, and clean, stable power. Real-time monitoring and control with Corsair Link Monitor and control your AX1200i with Corsair Link Dashboard (larger image) Put the AX1200i under your control by connecting it directly to a USB header on your motherboard with the included cable, or to a Corsair Link Commander (available separately). Then, download the free Corsair Link Dashboard software for unrivaled power supply monitoring and control options.Monitor power input and output, efficiency, fan speed, and internal temperature, directly from the Windows based application. Or, take it to the next level and set up and modify fan speed profiles, or even select from virtual “single rail” or “multi-rail” software modes, with selectable OCP points.Stable and Reliable Power DeliveryDSP-controlled, real-time voltage regulation helps ensure that your valuable components receive clean, stable power.Less Heat and Lower Operating Cost(larger image) (larger image) The extreme efficiency of the AX1200i earns it coveted 80 PLUS Platinum certification.

    • Corsair AX860i is the cleanest sine wave 860 Watt computer have tested in a long time.
The Corsair AX860i 80-Plus Platium certified DSP Power Factor Corrected power supply is the best clean power supply with power conditioning built in and tested at fifty degrees Celsius. Its consistent and reliable. Can support two Evga GeForce GTX 780 Titanium (3 GigaByte GDDR5 memory each) video controllers easily. If user is using two Evga GeForce GTX Titan-Z Hydro Copper (12 GigaByte GDDR5 memory each) video controllers, then best to purchase the Corsair AX1200i with 1200 Watts power supply instead. <Note if user really must have four Evga GeForce GTX Titan-Z Hydro Copper video controllers, then he shall surely need the Corsair AX1500i with 1500 Watts power supply to support all that and the six Corsair Hydro Series 110 required to cool.> Then the obligatory 48inch tower case is required just to prevent the excess heat inside from melting away the SATA data cables and fan cables. This is the cleanest sine wave operating 860 Watts power supply have tested in a long time. The fan only comes on when the processor is over 6 Giga Hertz. The 48inch tower case should have something to influence that result. Many folks actually believe that a large 1,200 Watts power supply is too much power. The truth is... a clean sinusoid is preferable to a raw brute force sine wave. A great computer power supply will provide "active" (be that analog or digital controlled) power factor corrected output. Meaning the user need not worry that the lessor (or questionable brand) power supply can add to, "color" the fine electrical characteristics that a digital circuitry requires. A perfect sinusoid for a user should keep up with the dips and rises while providing clean power. AX860i has such characteristics of a great computer power supply. The Corsair AX860i power supply has active conditioning keeping the power output Watts stable under all situations, and allowing the user to work without a doubt. Much engineering thought has gone into this product as its more of a hybrid power supply instead of the "me too" manufacturing of the typical computer power supply. Corsair AX860i is cooler operating than the CoolerMaster Silent Gold Series and Gold Series computer power supplies. There is no discernible hum and has clean electromagnetic harmonics contributing to a quiet room. Remember: Digital circuits (requires clean harmonics) eat what is fed, and transients cause permanent (non repairable) damage to computer components. Note: As with all modern, post A.D.2006 power supplies... Users please remember that quality equipment is very exciting on arrival, as one is assembling these precise products consider which connector goes to what. Because have heard and seen many products "done in" because all electrical cables are black or have similar type connectors. That mother board "auxiliary power" connector (8pins, some power supplies come with a 4pins + 4pins connector) should never be thought of as a PCI-E or PCI-X peripheral 8pins, or 6pins + 2pins connector (just because some connectors can be separated.) Check the main logicboard (mother board) assembly guide. And then read the power supply product sheet for clarity. User should compare both product information before any assembly. ... show more

    • The Best PSU for PC Money Can Buy!
Size: 1500W
This PSU is undoubtably the best PSU for your PC. Efficiency level of at least 94% even at 100% load. Far as PSU goes, the only other Titanium grade option is mainly for servers, not for PCs. So this PSU from Corsair will be the BEST you can possibly get for your money. You get an abundance of connectors and thank God for the backward capabilities of the connectors. Unlike EVGA Classified PSU, which comes in Generation 1 and 2 where connectors for either generation is not compatible with the other generation, you can use the braided connectors sold by Corsair if you happen to have a set from your AX1200i. So if you're looking to upgrade from AX1200i to AX1500i, you can migrate all the connectors without problems. However, the connectors for all other Corsair PSUs are not compatible. It's also important to note that the connectors are long which indicates this PSU can easily support the current models of supertower PC cases. To give you an idea, I have had no problem using connectors on my CaseLabs STH10 with pedestals, which the PC case is over 4 feet tall. The lengthiest connector had to be the CPU connector and the distance from the PSU to the connector on the motherboard is approximately 3 feet, but the provided connector was long enough to cover the distance. Compared to AX1200i, this PSU is about 10cm longer, so after installing all connectors you may face some cramped space in your PC case where PSU is located. Based on my experience, Corsair 900D case may run into this cramped space issue when you decide to install both 480mm AND 240mm radiators in the bottom chamber. In fact, you probably won't be able to fit 240mm radiator and this PSU on the same side because I struggled a bit when installing 240mm radiator and this PSU on the STH10 (it was tight, but I was able to get both components squeezed in while minimizing pressures on the connectors). So if I struggled with STH10, then my experience tells me that such an installation is not possible on Corsair 900D because the bottom chamber is smaller for this case when compared to that of STH10. But then again, this shouldn't be too much of a problem for people since the space issue can easily be resolved with smart build design modification. That being said, if you are building a PC anything less than a full ATX, no sli nor crossfire setup, maxed out RAM, extreme CPUs etc., you should probably go with other PSU models because this is clearly an overkill for anything less. My current build includes two R9 295X2. YES, TWO! And those who are aware, that VGA is power hungry. Yet, with this PSU there's still enough headroom. When my PC is on, the fan on the PSU does not even turn on. But the fan does kick in during heavy load, especially when gaming on 4k resolution and both VGAs are being fully utilized. Still, no shortage of power here. My only problem is not directed at this PSU, but the option it provides. Specifically, the Corsair Link. Corsair really need to fix that God awful device or completely scrap the concept in its entirety. The software for Corsair Link is still unbearable to use and trying to get it to work properly is like pulling teeth. But to cover all basis, this PSU does allow the option to tap the Corsair Link functionality for monitoring power usage purposes. But I doubt most will connect this PSU to the Link especially since an alternative option is available - you can monitor either via Corsair Link or via internal USB which connects directly to your motherboard. I think most users will opt for the latter and the necessary USB connector is included. Strangely, Corsair did not include a Link adapter with this PSU, unlike AX1200i which does include the Link adapter and the connector. ... show more

    • Top of the line - costly, very high quality with bells and whistles.
Review Image by Thermocouple Thermocouple
I have had this power supply, AX860i, for nearly 5 years. It has never let me down. I have it powering a system with two overclocked R9 290s, an overclocked i7 4790k, a water pump,8 fans, 2ssds, wifi card and of course mobo. The "i" series allows for unique and fun data collection not supported by nearly any other line of models. I never stressed the unit to hard. I stress test up to 800 Watts only so I have headrom. I wouldnt be afraid to push spec with this unit if I could. Using the logging capabilities I plotted my unit's efficiency and included it here. You can see it matches their claim well. I attribute low wattage inefficencies to start up and shut down. Otherwise, my results match their spec's claim with 93% max efficency at 414 Watts. The fan stays completly off at low heat, which is great. When it turns on it is very quiet. Finally note that this power supply may be the largest wattage available in the smaller, "regular", form factor size. I cant fit the larger supplies with my radiator, so I luckily ended up with this power supply. Pros: High quality build, heavy duty parts. Full watt spec on 12V rail. High wattage for small form factor. "i" series has unique data collection capabilities. Quiet, cool, and efficent operation. Zero fan speeds at low heat. Cons: Expensive. Thats all I can think of. Rarely goes on sale or has special deals. Edit - At this price point standard sleeved cables should be included. This is a very top line consumer power supply with extra cpabilities. If you can justify the cost, you will probably be very happy with the supply. I am. ... show more
