Bottom Line:
This power supply does what it's supposed to do although it's a shame it's not more efficient. All and all, it's a really nice unit. And at $150 it is expensive, but delivers on performance and minimal noise.

Specifications
Let's take a look at the label on the side of the power
supply and see what they're trying to sell us here...

2.5A |
| Max Combined Peak Wattage |
220W |
336W |
12W |
4W |
15W |
| 450W |
With 45A on the 5V, this power supply obviously
isn't trying to be ATX12V2.01, but that OK. 28A on the 12V is more
than enough for most of us out there. Now let's look at what connectors
we get and the quantity of each...
| Fanless 450 LION |
QUANTITY OF CONNECTORS |
| ATX connector |
20-pin |
| 2 x 2 12V connectors |
1 |
| 2 x 3 PCIe |
0 |
| 6-pin Xeon/AUX connector |
1 |
| 5.25" Drive connectors |
7* |
| 3.5" Drive connectors |
2 |
| SATA Drive power connectors |
2 |
| Fan only connectors (Thermostatically controlled 12V
only connectors) |
6 |
* One of the cables have EMI filters for use specifically with hard
drives.
I'm rather disappointed that the power supply didn't have a 24-pin ATX
connector. Not that using an adapter is a big deal as the loss
I've recorded is barely over 1%, I just think it makes more sense for
someone to adapt a 24 to a 20-pin connector, if need be, rather than
the other way around. There's no PCI-e connector, but there is
a filtered drive Molex, so if I were to use this with a PCI-e card, I
would just use an adapter on that connector since 99% of the time I have
more than one hard drive and would be hard pressed to determine which
hard drive I'm going to use the filtered power connector on (sort of
like picking a favorite child or favorite Tampa Bay Lightning defenseman.)
After the power supply ran for another 15 minutes with
the fan spinning, the temps were back down to 42C as per my Compu-Nurse. I
hit the power button for the fan and proceeded with the tests. Since
this power supply is "only" a 450W and my Test Three runs the 12V 2A over
spec as it is, for a grand total of 479W, I didn't do a "full load" test.
