Hyper Path, an exclusive hyper link between IC and the relative components, provides super efficient connection from the transformer to components. The signal can be transfer directly without any energy loss.

5 out of 5 eggsGreat Modular PSU

Pros: I really like this power supply. Simple design and easy to set up. Truly modular unlike many power supplies that have some modular and some cables non removable. Comes with a fan control unit. Cables were able to reach anything i needed them to in the very large cooler master cosmos II case.

Cons: no major cons. didnt really use the fan control unit part because it didnt seem to fit well on my cooler master cosmos II case. This i felt kind of strange since they both are cooler-master products....

Other Thoughts: great psu solid design truly modular and highly functional.

1 out of 5 eggsDay # 3 and still nothing.. ????

Pros: My pros will always be overshadowed by the fact cooler master can't fix this.

Pros The case is awesome except below.

Cons: Great Idea except the bottom 3.5" Bay is useless. Nothing will snap tight like in all the other bays... I cannot fit my fan controller in.

Cons- Cooler Master. ....Day # 3 and still nothing.. ???? Do I need to get a refund on all of this and go use thermaltake cases and power supplies and water coolers. I have never had an issue with any of their products in 10 years. Everything from calling and it ringing non stop for hours on end too delayed emails, and 20-30 minute response times with live chats, not to mention the case does not work...properly! Has made this one bad experience, yet amazingly the response time for selling the products and recomending this and that was lightning fast. It should not take this long to realize you case is defective, my fan controller is useless, and because of that and the long delays with everything else, I have zero faith or trust in the Seidon 240M water cooler you convinced me to put on my maximus V Gene and my i7 3770K you make Thanks for nothing!

Other Thoughts: I do not hold newegg at fault. This is a MFG defect. I can sy this. With the customer service, excuse me lack of, I will never own another cooler master product again. Between Case Cooler and Power Supply I spent almost $500. The fan controller is useless the case because of this really bothers me. Based on my experience I am very disappointed. I do give new egg 10 eggs Cooler Master.... Thumbs down....Back to Thermaltake...

5 out of 5 eggsGreat PSU

Pros: I bought this be cause its a CM product and well can't go wrong with CM. I also bought this for the fan controler, it's modular, and to CrossFire two 7850's. Fan control works really nice, love the modular aspect, and has plenty of power.

Cons: none that I can think of

5 out of 5 eggsFantastic Power Supply

Pros: Very quite operation. Power output is very stable from this unit even when under high load from an overclocked cpu with a GTX 570 that is overvolted.
Fan controller is a nice touch, has 3 headers you can connect to on the controller that are adjustable as well as 2 more that are set to 7volts on the psu itself.

Cons: If you do not like bright blue LEDs you may need to cover it up on the controller.

Other Thoughts: This unit finally fixed my crashing issues that were caused by an Ultra 800 unit that tested fine but could not provided correct amperage for the GTX 570.

4 out of 5 eggsreliable and quiet

Pros: comes with plenty of power cables, clean design, very stable and reliable PSU

Cons: the control panel for the drive bay was not the easiest to get into the system, but it does work at advertised.

Other Thoughts: I think it would have been nicer to use sliders instead of dials for the speed controls.
