Professional Series™ Gold AX1200 — 80 PLUS® Gold Certified Fully-Modular Power Supply

£290.98 GBP

The CORSAIR AX1200 provides the power level, reliability, and stability required for the ultimate SLI and CrossFire gaming PCs. It delivers more than 90% energy-efficiency, and is built to CORSAIR&rsquo,s renowned quality standards with one aim alone &mdash, to deliver the precise features and performance that enthusiasts demand.


A Fully Modular Cabling System

All cables detach from the power supply. During installation, this gives you the flexibility of using only the cables you need for a clean system build with optimal airflow. And, when it’s time to replace or upgrade your power supply, it can be removed from your system without interfering with your cabling — the cables stay in place and connect to your new fully-modular Corsair power supply.

Incredible Efficiency

With 90% efficiency at 50% load, the Corsair Professional Series Gold power supply runs quieter, generates minimal excess heat, and saves you money every month. It's earned the 80 Plus® Gold seal of approval, your guarantee that you're making the right choice for smart, efficient power delivery.

Corsair Professional Series Gold AX1200 features:

  • Supports the latest ATX12V v2.31 and EPS 2.92 standards and is backward compatible with ATX12V 2.2 and ATX12V 2.01 systems

Geeks 3D tests the AX1200

I have now the PSU that will help me to make FurMark more aggressive with our graphics cards. But AX1200 tests are not over. I have to play now with a 3-way SLI of GTX 480 and with overclocked GTX 480… in another article, because it’s getting hot in my lab…

AX1200W gets a 9.8 overall score and Jonny Guru Recommended Award

There is a whole lot to like about the new Corsair AX1200, and very little indeed to hate. Lots of power, lots of connectors, and all of those connectors come off if you want them to. And we can't forget about the efficiency, which easily outclasses everything else I've ever tested. I got 94% efficiency out of this thing at more than one point, folks! Do you need any other reason to buy one?

Corsair AX1200 wins Hardware Heaven Gold and Performance Awards

Finally we have the real world test results where we see the AX1200 handle a high end overclocked GTX 480 SLI / Core i7-980X system with ease. Not only this, it did so with lower noise levels, temperatures and power use than a similar model. All of these aspects benefit the end user with the most important being money saved through high efficiency and lower power draw at the wall. A near flawless product from Corsair which continues to enhance their reputation for producing the industry's best PSUs.

Corsair AX1200 Wins Must Have Award

The AX1200W power supply from Corsair isn’t just their best unit, its easily the best power supply on the market right now and we think it will be some time before we see results like these again. We were so surprised with some of the results that we reran them multiple times over a period of several days – just in case our eyes, and testing equipment were playing tricks with us.
