Both of the Demons (both the 480W and 580W) offer the same amount of each type of connector. There are 2 chains of 3 Molex
connectors and they each terminate with a 4-pin floppy connector. A nice bonus for those who have jumped on the
Serial ATA bandwagon is that these PSUs include 2 Serial ATA power connectors. Unfortunately, only the 20-pin ATX connector
was sleeved in a nylon mesh. Each of the connector chains however, have been tied off at an interval with cable ties which
does neaten the cables slightly.

I found the amount of Molex connectors on the power supplies were inadequate. In my main computer, I ran out
of plugs before I had connected all my drives and fans, even with a fanbus controlling 4 of the 5 fans! I resorted to digging
up y-splitters to power all of my drives.
Another small issue was the process of removing the power supplies. Though this is a relatively minor issue
unless you swap power supplies often, the 4-pin connectors held death grips on my Radeon 9700 and my floppy drive.
It required a heated struggle between my hand, the sharp edges in my case, and the connector to loosen its grip on the 4 pins.
Normally this would not be much of an issue for me, except that my Radeon's 4-pin connector actually started to shift left
and right as I struggled to loosen it from the PSU's grip.
Both of the power supplies look identical. In fact, from the outside, the only thing that differentiates
the two are the color of the case (480W is silver while the 580W is black), the color of the clear fan (blue versus red)
and the sleeves on the ATX connector (blue versus black). Both units sport and 80mm and 120mm fans, both exhausting air
from the rear of the case.

What I find odd is that Powmax decided to stick the 80mm fan on the outside of the power supply,
putting it within the case rather than the more common placement of the fan on the inside towards the back.
When the cases of the units wered up, there was plenty of room for the fan on the interior. While this may
not cause a problem for most, be aware that it adds an extra inch to the length of the power supply and might be a
tight fit for those with smaller cases. On the plus side however, both fans are LED fans, emitting a blue or red
glow (depending if it's the 480W or the 580W model) inside the case.

Furthermore, both ran quietly, nothing loud enough to distract you from doing work with no other sound in the room.
They were much quieter than the previous power supplies I had in use. It did not feel like there was a lot of
airflow exhausting from the units though this may be a side effect of having a grill that encompasses the
entire back side of the units.

The power supplies also offer a switch to change the voltage from 115V to 230V. I once again question the
placement of this switch as it ends up on the inside of the case, while the norm is to place this switch in a more
accessible spot such as on the outside by the power switch and electrical plug. On the back facing the outside of course,
are the power switch (which nicely lights up when it is receiving power) and a power inlet. On the 480W power supply, this
inlet is green, which contrasts with the rest of the PSU's color scheme (which is blue). Again, a minor issue, though
I did find it odd for Powmax to break the color scheme on the 480W while it kept to the black/red scheme for the 580W.
One problem encountered while handling the physical aspect of the PSU was that though
the 480W fit easily into my Lian-Li PC60, the 580W would not. It seems that though they look to be identical
in size, the 580W is actually a millimeter or two taller, making it unable to fit inside my PC60. As a result I ran
it outside of the case. It did however, fit fine in my cheap beige case (go figure).

I have to say that if I judge purely on this, both of the Demon's would fall horribly low on the food chain. Though
they are high wattage, they feel like the cheap no-name brand 150W power supplies from the days of the PII. Whend up,
both power supplies continue to look like twins on the inside. In fact, if placed side to side, they look identical. Though
that is not necessarily a bad thing (though it begs the question what makes one a 580W PSU versus a 480W PSU), what is
disconcerting is the lack of innards that are contained within the PSU. The heat sinks, line conditioners, and capacitors
look like the bare minimum needed to run a computer, let alone push out the high-end wattages that it claims to offer.
