Corsair AX1500i
Digital ATX Power Supply — 1500 Watt Fully-Modular PSU


1500 Watts of continuous power, an incredible 94% efficiency rating, and CORSAIR iCUE desktop monitoring control make the incredible AX1500i the best enthusiast PC power supply you can own.


AX1500i defines the state of the art for enthusiast-grade PC power supplies. It provides 1500 Watts of continuous, digitally-controlled power on 15 Amp circuits of 115V or higher, and 80 PLUS certification with an incredible 94% efficiency rating.

Zero RPM Fan mode ensures silent operation at low and medium loads, and the fully modular, low profile cable set makes for easy installation and great-looking builds. CORSAIR iCUE integration lets you monitor power usage and efficiency and customize performance, directly from your Windows desktop. The AX1500i lets you have it all, and it’s the power supply you want for your ultra-high performance PC.


If you’re building ultra high-end performance systems or pushing world overclocking records, you know it when even 1200 Watts just isn’t enough. The AX1500i reliably delivers 1500 Watts of continuous – not peak – power on demand. And, you don’t need any special household wiring to make it happen… you’ll get 1500 Watts of clean, stable power on 15 Amp circuits of 115V or higher.



The AX1500i is designed around a DSP for increased efficiency, tighter voltage regulation, and superior electrical specifications. The elegant, DSP-based design reduces internal component count and allows for better control of electrical ripple and noise.



The AX1500i, simply put, approaches near-perfect efficiency like no other desktop PC power supply has ever done. Amazing efficiency has so many benefits – not only does it lower your operating costs, but it generates less heat, too. And that means that there’s less cooling required, which lowers noise.


In fact, most of the time, no active cooling is required. The fan simply doesn’t spin. And when you’re pushing it hard, the thermally controlled fan adjusts its speed to match demand. The custom-designed fan is extra large, with a diameter of 140mm for low noise even at full load, and it uses a fluid dynamic bearing for quiet, reliable operation.


Connect the AX1500i to a motherboard USB header with the included cable, and you can use CORSAIR iCUE to monitor power input, power output, efficiency, and internal temperature in real time. You can customize fan speed response, and set up your AX1500i to operate as a single-rail power supply, or with multiple virtual rails with customizable OCP points.


AX1500i is fully modular, which means that there are no permanently attached cables. This greatly simplifies installation and allows you to use only the cables you need, for a neater, cleaner build. This can also improve performance: fewer extraneous cables in your system can reduce airflow obstruction.

Power Supply Units [PSUs] are often overlooked during a PC build despite its crucial part in determining the reliability of the entire system. All your PC components depend on PSU for power. Even if you’re on a tight budget, you don’t want to make any compromises when it comes to the power supply. We’re here to discuss factors you need to consider before purchasing the PSU for your rig.

Factors need to be considered before purchasing a PSU -

Wattage Requirement: There is no point in buying a PSU with way more potential power than you’ll ever use. A PSU calculator web page or software can be handy in finding a rough estimation about the wattage requirement of your build. However, it is not recommended purchasing a PSU just above your system's power needs. A PSU delivers maximum efficiency with 40 to 60 percent load. Besides, the performance of a PSU declines with time. So, you better opt for a PSU capable of taking you through your next few upgrades for multiple years.

Physical Dimensions of the PC Case: You must buy a PSU that fits inside your PC case. Higher-wattage PSUs tend to be a bit longer [compared to typical 5.5 inch PSUs] to house the additional power components they need. This may create issues with cable routing or even with placing other internal components inside the case. So, it is a must to go for a PSU compatible with your PC case.

Type and Number of Connectors: Different PSUs come with different types of power connectors, including 20/24-pin power, 4-pin ATX12V, 4-pin Molex, floppy, SATA, 6-pin PCI-Express graphics and 8-pin PCI-Express graphics. You must get a power supply with connectors your PC components required. If you don’t find required connectors in a PSU within your budget, check what cable adaptors the PSU includes to extenuate the problem.

Modular or Non-Modular: If you have limited space in your case, it’s worth paying extra for a modular power supply. A modular PSU let you plug in the power cables you need and leave the extra ones. This facility will help reducing cable clutter that can hinder airflow and heat up the atmosphere inside the case.

Power Efficiency: PSUs convert voltages from wall outlets to lower levels as required by the PC. The power supply wastes some power as heat during the conversion. A PSU with higher efficiency means it can power the PC with minimum loss of electricity. Anything 80% and above is good. With a more efficient PSU, you can end up saving money as it will require less electricity to power your PC. The "80 Plus" Certification shows that the power supply has been tested to have 80% efficiency at every load. There are higher tiers of 80 Plus that show even higher efficiency such as 80+ Bronze or Silver. As the efficiency of the PSU gradually drops during the lifespan of the PSU, it is recommended to opt for a PSU with the maximum efficiency possible as long as it agrees with your budget.
