For the average computer owner, that measly 220W power supply is more than enough to power their system. For the enthusiast, it's all about power, and demand for power can be double or even triple that of the average owner. Not only do we have to run our highly over clocked computer, we have to power other items such as Cold Cathode Lights, Fan Buses, LCD displays, a dozen fans, a water cooling setup, and maybe even a TEC/Pelt, and the more items we add, the more power we need. Yet, the enthusiast also needs to keep looks in mind. Well, thanks to companies like MGE, you have a supplier for your demanding needs.

Packaging and Contents
The Vigor 450 power supply comes nicely packaged in a black and red themed cardboard box that lists all the features in handy, eye catching yellow boxes. You can see exactly what you've purchased through the big clear window in the front of the box.
Inside the package you'll find the PSU, a power cord, two plugs to convert a standard molex to SATA and four mounting screws.
The back of the XG Vigor 450 is different than most power supplies on the Market. Since this is a two fanned power supply, there is no fan in the back, instead there is honeycomb mesh. The honeycomb mesh pattern helps maintain the structural strength of the panel and offers very little resistance to airflow. A very thoughtful inclusion is the manual adjustment knob to raise and lower the speed of the fan. If you are looking for "quiet computing" adjustable fans in your PSU are a huge benefit. Yet, one downside to this is that the lower the speed, the dimmer the blue LEDS are. It would be great to see the LEDS powered by the power supply itself in future revisions, yet it’s not that important.
For a performance based, enthusiast level machine, the 350 watt power supply is no longer considered adequate. The product description in the lineup of some newer graphics cards recommend a 450+ watt power supply. While this certainly is important, don't base your purchase decision strictly on the amount of power a unit can generate. The difference between a clean and dirty power supply can be the difference between a stable gaming rig and a constant headache. The most typically sought-after power supply specification deals with the units Power Filtering Circuitry or PFC. PFC comes in three basic forms; active, passive or none. Simply put an Active PFC is better than passive and passive is better than having none at all. The difference between active and passive is in the makeup of the filtering circuits themselves. Active relies on solid-state electronics to monitor the voltage and current levels and reacts within milliseconds to a change in either parameter. Passive filtering is generally less accurate and has a longer correction time than active filtering to changing line levels. With no PFC system in place on your power supply, you're basically at the mercy of the utility voltage coming out of the wall. In all of these cases, a good Uninterruptible Power Supply (UPS) can help with 99% of bad line-voltage problems before they get to your PC power supply.
Serial ATA is here to stay and more power supplies are coming, like this one, with Serial ATA drive connectors. The Serial ATA connectors are offered, yet are not built into the power supply. This is a nice feature to have, as not everyone has a SATA, yet it would have been nice to see these wires sleeved.

The rest of the accessory power connectors are arranged as such; there are a total of eight four pin "Molex" connectors and two four pin "floppy" connectors on a total of two strands. The Molex connectors are pre-fitted with an "easy grip" system to facilitate the removal and installation of the connector. This makes hard drives and CD-ROM drives very easy to attach the connector to, but if your video card requires a four-pin Molex connector, then there could be issues. To prevent damaging the easy grip tabs on the connectors, use the "Y cord" that should have come bundled with your video card.
The XG Vigor 450 includes a feature that is slowly becoming common in all top of the line powersupplies on the market, a window. The window in the XG Vigor 450 is tinted blue, to match the LED fans and the sleeving. There are two windows on the XG Vigor 450, on opposite sides.
The Vigor 450 is a two fan power supply. On the bottom there is a 120mm blue LED fan, and on the front, an 80mm blue LED fan. The front fan is mounted on the outside of the PSU housing, this is an oddity for sure, yet it has an advantage it, since there is also no rear exhaust fan this PSU has a smaller foot print and will fit into smaller cases that a full sized 3 fan PSU wont fit into.
Installation of the XG Vigor 450 went as easy as any other power supply, unit we got to the video card. As I mentioned about the Molex connector, the easy grip tab will require some manipulation, or you can just use the "Y" cord that came bundled with your video card. The cable length and connector arrangement is very stylishly designed so there are not miles of unused wires.
The XG Vigor 450 has a lot going for it. The easy grip Molex kits built-in are a very nice touch, the sleeved wires make airflow much better in anyone’s case and the chrome housing with two blue windows makes this one hell of a power supply. Solid power performance that, given the power meter readings, still has plenty in reserve. The power is obviously clean enough to keep an overclocked Pentium-4 chugging along. It’s is also great to see the inclusion of power a manual adjustment knob to raise and lower the speed of the fan. Given the quality of the XG Vigor 450, VelocityReviews awards it the ISH award!
