| FEATURE & BRIEF |
COMMENT |
|
Universal Video Card Support
Support new PCI-E video card technologies
|
Compatibility is nice,
though power-guzzling PCIe graphics cards aren't exactly Green. |
Smart & Silent Fan
Control [ S²FC]
Smart thermal control to balance noise & cooling. |
The same fan controller
we've recommended for years. |
|
Super High Efficiency [up to 85%]
Optimal solution for low energy consumption, noise & heat.
|
Low power consumption
is certainly Green, though efficiency is less important than the consumption
of the overall system. |
Active Power Factor
Correction [99% PF]
Reduces line loss & power distortion. |
Reduced line losses benefit
the utility company and mean less power has to be generated at the power
station. |
|
Double Ball Bearing Fan
Increases airflow & lifetime and reduces rotation speed and noise.
|
The safe choice for a
high heat environment like a power supply. |
Universal AC Input [Full
Range]
Plug & run safely anywhere in the world. |
A small environmental
benefit in that less overstock is likely to be produced when there is a
single international model. |
5 Year Warranty
Our Commitments to superior quality. |
Pretty good if you like
warranties. |

EXTERNAL TOUR
The Eco Power conforms to the SFX12V form factor, so it is about half the size
of a standard ATX12V power supply. A steel adapter plate is included so that
it can be installed in regular ATX systems. Its small size lends credibility
to its Green claims — less volume means less overall materials went into
its construction, which in turns means a smaller environmental footprint.
A close look at the label reveals that Seasonic's internal model number is
SS-300SFD — the same model
that we tested with an efficiency above 85%. The differences between that
unit and the Eco Power 300 are minimal; it's most likely only the extras included
in the retail package that set them apart.
Smaller physical footprint = smaller environmental footprint.
An ATX adapter plate allows the Eco Power to be installed in standard cases.
The casing is unpainted steel.
This restrictive grill is typical of SFX12V power supplies. What does that
mean for airflow?
CABLES AND CONNECTORS
There are five cable sets and two adapters, all of which are quite short. Regular
ATX-style cases should be alright, but don't expect to do much in the way of
fancy cabling. The limited set of connectors is enough for a simple system,
but it's not really intended for use in high end or gaming rigs.
- 12" cable for main 20+4-pin ATX connector
- 13" cable for 4-pin AUX12V connector
- 1 x 25" cable with three 4-pin IDE drive connectors
- 1 x 19" cable with two 4-pin IDE drive connectors
- 1 x 16" cable with two SATA drive connectors
- 1 x 4" adapter from two 4-pin IDE connectors to one PCIe graphics connector
- 1 x 6" splitter from one 4-pin IDE connector to two floppy connectors
