Summary: I thought it was going to be completely modular and it wasn't but I have to say that it's been great so far. I was able to connect my GTX 770 SC Graphics Card but I'm going to need to upgrade to a different power supply in order to add a secondary graphics card for SLI.
Summary: Nice PSU, well built, comes in a beatiful package, backed up with good warranty, and priced fairly good, the only down side is its not fully modular, the CPU and Motherboard ATX power cables are connected, so if you are planning to use custom cables in your rig this is not for you, from the name "Enthusuast, you would think its buitl with that purpose in mind.
Summary: I purchased this for my new mid-range gaming system and it works perfectly. It has plenty of connectors for every possible installation. One thing to keep in mind, the fan on the power supply does not run until a specific load is being used. This worried me because I thought that the fan was not operational and that the power supply would overheat. After contacting support, they informed me that this is normal operation for their power supplies.
Summary: Although this is labeled as a modular power supply it mostly is not. The 20 + 4 pin, the 8 pin aux, a strand of molex, strand of ATA power and 2 PCI-E 4/6(cant remember which) are all run directly into the PSU and not removable at all. Other than that solid power, does have all the connectors I needed to do SLI on GTX 660TIs as well as my peripherals. I still like this purchase but really wish only the 20+4 and 8 pin aux were forced connectors.
