In The Box
This Tuniq model is a standard sized unit so fitting it into your existing enclosure should be no problem. It doesn't offer a modular design, but it does make sure to wrap all wiring harnesses in a mesh material to make cable management easier.
As far as power ratings are concerned, you get a very workable level across all rails. The 3.3v rail is rated at 24A and the 5v rail is rated at 30A with a maximum output from these two rails rated at 170 watts. There are four 12v rails rated at 20A each, so you also have a pretty hefty main power rail for your add-on cards and such. Maximum output from the 12v rails is rated at 810 watts.
Also included in this package is a supply of zip ties for cable management and two adapters that convert the PCI-E8 connectors to standard PCI-E. This allows those who may not be ready to upgrade to the newer video cards to still feed a multi-GPU setup.
Like most models hitting the market today, the exterior panel has very little in the way of features. This makes more room for cooling, a growing concern with modern power supplies. This mesh panel allows for large amounts of air to travel through the casing and keep the internal components cool.
Feeding that mesh exhaust area is a large 135mm fan. It is a variable speed fan that automatically increases speed (and airflow) when the unit warms up. While never very loud, when it is running at system idle speeds you simply cannot heat it. It is a very silent fan and will go well in a box with low sound as a primary concern. It is not totally silent under load, but it is not very loud at any time.
As noted above, this model is not a modular design. While it is a nice feature to have, it is not that important to many. To make certain that things run smoothly, you will notice that there is both a plastic grommet protecting the wiring harness as well as the mesh material going into the housing itself. This gives maximum protection to the wires and presents the least chance possible for wear to cause contact between the metal enclosure and any bare wires.
When it comes to hooking up your components to this new PSU, there is a good deal of flexibility and also a lot of room for future upgrades. The primary connector is the 20+4-pin variety so you won't be left out on the cold if you happen to have an older motherboard that still requires a 20-pin main port. It also includes both 4-pin and 8-pin auxiliary connectors allowing for even more flexibility. For peripherals you get six Molex, two FDD, six SATA, two PCI-E and two PCI-E8 connectors. And don't forget, if you have a multiple GPU system and need four PCI-E connectors, there are the two adapters noted earlier to let you give it all the power it needs.
