GT3-BH CaseFormer staff writer - December 27, 2007
The GT3 comes with a power supply installed inside. It is a good thing it is included for a couple of reasons. First, due to the unique size of the GT3, being so narrow, most power supplies will not fit. Secondly, GTR Tech has questioned how power is used in a PC. They wonder if the size recomendations from PC vendors is really necessary.
According to GTR Tech, "what’s most important is that the PSU provide a safe and reliable source of power for all the platform scenarios that are available for this case. The sticker on the side of the power supply is misleading as it references total combined output of a few of the power rails. GT3's power supply is rated at 350W at 95(35C) degrees F. Since the air intake on the GT3’s power supply is on top of the case, it is drawing in cooler air than 95(35C) degrees F, which will make the power supply run cooler, thus making it more efficient. So its real world output is greater than 350W."
"GTR contracted FSP to design GT3's power supply, the FSP350-60MB. GTR specified its power supply requirements with one premise: to support all PC components which would physically fit within the GT3 enclosure. To that end, GTR Tech has yet to find a GT3-compatible configuration that exceeds the power supply's capability."
All power supplies have one form or another of Power Factor Correction (PFC). What is PFC? Power Factor Correction (PFC) allows power distribution to operate at its maximum efficiency. There are two types of PFC, Active PFC and Passive PFC. The GT3’s power supply uses Active PFC. The preferable type of PFC is Active Power Factor Correction (Active PFC) since it provides more efficient power frequency. Because Active PFC uses a circuit to correct power factor, Active PFC is able to generate a theoretical power factor of over 95%. Active Power Factor Correction also markedly diminishes total harmonics, automatically corrects for AC input voltage, and is capable of a full range of input voltage. Since Active PFC is the more complex method of Power Factor Correction, it is more expensive to produce an Active PFC power supply.
I found the wires on the power supply to be plenty long enough to reach all areas of the case and they were neatly braided to help with organization and appearance inside the case.
On the bottom of the case, we have four feet. Now, these aren’t just any old feet. From inside the case, you can push on the center pin that holds the feet in place, and remove the feet all together. Big deal, huh? Well, actually it is here because once the feet are removed, you can lay the case on its side and use it as a home theater PC that would blend nicely with its highly polished black finish. Of course, this would also necessitate the removal of the Wingdle (handle) from the top of the case.
