AX1200 1200W ATX 80 Plus Gold Modular Power Supply (CMPSU-1200AXUK)

The Corsair Professional Series Gold power supply pushes the state of the art for reliable delivery of clean power under imperfect conditions. If you require mission-critical stability or you simply want one of the best power supplies available, the Professional Series Gold is for you. 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. 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.

There is something about Corsairs understated quality and aesthetics. They are on another level to anyone else. Great PSU, paired with my Corsair 650D and even splashed out on the braided cables. Just awesome

Just Suprerb!!

This is just the best, end-of. The size is really nice and small and has tons of power and tons of plenty of leads to power nearly everything you would want in a PC.

Corsair - The quality of their products is just out of this world.

Overclockers UK - You are a superb company. No wonder everyone comes to this website. From Support to Delivery to Prices, they are the best.

5/5 for Corsair & Overclockers UK hands down.

We canny do it captain

You won't hear Scotty saying we "just don't have the power" with this baby. I was going to get the 850W version but, decided to bite the bullet and go for this. I don't regret it, it has more than enough power for my system and then some. Its cool and very quiet.

Power to the people

Just bought this from you guys and have been running this for about 2 weeks and have to say its doing a sterling job. Its quiet and keeps my monsta of a computer juiced up. It powers an i7 920 at 4.0ghz, 590 quad sli setup unbelievably well. Its a steep price to pay but if you want the best quality power for your componants then look no further than Corsair. Their 7 year warranty is just a testament to how confident they are in their product, which is also a peace of mind to us consumers.

As for overclockers, very speedy delivery which we all know all too well.

Full 5 stars for OcUk service

Full 5 stars for Corsair and this unbelievable product.

Bought this for running overclocked 980x and 3 overclocked gtx580s it has never missed a beat and runs nice and quiet.

Worth every penny.

Great power supply. Running a Quad SLI with 8 hard drives and two CPUs required this beast. And I'm glad I got it. I've stuck with Corsair for years now and they are the best when it comes to customer care and their products are well made and meant to last. This is my 4th power supply from them and all were top quality. Bottom line it is worth the extra money as you'll not have to replace your PSU for a long time.
