This power supply is extremely quiet and cool running. This one utilize the latest technology for better efficiency and performance.
None so far other than being a little pricey

Unlike most computer power supply, this one generates only 12 volt on the main transformer and then utilizing DC to DC voltage regulator modules to generate 5 V and 3.3 V similarly to what a motherboard that does to generate power for the CPU and computer memories. 's done this way to get greater efficiency. At medium load, the power conversion efficiency is as high as 87%. The permanently attached cables on this unit is all I needed and did not need to use the modular plugs for additional cables. On the back of this unit there are four terminals. The two red ones are actually for video cards and are wired on rails three and four. The two black ones are connected to rail one.
The outputs from this power supply is extremely stable. I've practically do not notice any voltage jittery on any of the three outputs when subjected to heavy loads. The 12 V output is rated close to the maximum power supply output at 45 amperes which equals to 540 W. With this kind of rating, this unit should be able to power practically any single video card PC out there. All of the connecting cables are neatly braided and nice and long. The length should be more than enough to accommodate mid-tower computer.
I am extremely happy with the performance of this power supply. I do not actually buy this unit directly but got it as a warranty replacement to replace my earlier failed unit of the same capacity from Antec. To obtain warranty service, I went online and request an RMA from Antec. As soon as I received an e-mail from them with the RMA number and instructions, I mailed via parcel post the defective unit to them paying for postage about $10. In about a week and a half, I've received postage paid the better replacement power supply. Luckily I did not need to use additional cables to install because they did not supply me with any of the modular connection cables. This could have been a problem for those of you who has two video cards instead of one. Since this is a warranty replacement, Antec assumes that I still have the modular cables. In my case, the previous power supply doesn't have modular outputs. This power supply is actually built by Seasonic for Antec.
