Since it was introduced in early 2005, Seasonic's S12 series has been recommended
on SPCR more than any other power supply. We consider it a quiet reference,
against which other power supplies can be measured. Even so, the S12 is not
perfect — there are too many variations in individual circumstances for
one power supply to work for all users. For example, many potential users have
been disappointed to learn that the lower capacity S12's did not come with a
PCI Express connector — despite the fact that they are more than capable
of supplying enough power.
The special status of the S12 warrants a little bit of special attention. We've
looked at three S12 models previously, the
430 watt model and the
500 and 600 watt models, but a new revision that addresses the lack
of PCIe connector makes the S12 worth another look. This time, we're looking
at the baby of the bunch: The S12-330. 330 watts is enough power for almost
any desktop machine with the exception of dual-video card gaming rigs, but there may be differences in addition to capacity.
Unlike the changes made in the last revision, the new changes are concerned
with cosmetics and usability, not the internal design. This means that the newly revised S12's are quite easy to identify, not least because they sport a new,
more colorful and slightly smaller retail box. At the same time, some changes
have been made to the accessories bundled with the S12:
- Dr. Cable (a system for cable management) has been dropped in favor of simple
cable sleeving.
- The IDE to 5 volt / 12 volt fan-header adapter is no longer included
- A new IDE to 2 x Floppy adapter is included, as there are no longer any floppy
connectors on the base cables
The new box on the right is smaller but brighter and more visible.
Some other changes were summarized quite succinctly by forum user dhanson865:
- 6 HDD connectors (previously 5) - 330 & 380W models
- 6 HDD connectors (no change) - 430W model
- 9 HDD connectors (previously 6) - 500 & 600W models
- 4 SATA connectors (previously 2) - 330, 380 & 430W models
- 6 SATA connectors (previously 2 or 3 depending on US version or not) - 500W
model
- 6 SATA connectors (previously 4) - 600W model
- 1 PCIe power connector (previously 0) - 330, 380 & 430W models
- Longer (black) sleeved cables - All
- RoHS compliant - All
One final change is that the Fan RPM monitor cable has been removed. It is
no longer possible to monitor the speed of the internal fan. Most likely, it
was dropped because so many motherboards have trouble detecting an RPM signal
at the slow speed that the fan spins.
