The PSUs themselves do not appear much different than the early samples or the S12-430 except for the dual 6-pin PCIe connectors and a few subtleties. The contents of the box are also the same.
Clockwise, from top left: S12-600, box, Dr. Cable kit, instruction
booklet, mounting screws, Seasonic sticker, 4-pin Molex to 3 fan headers adapter,
AC cable.
There are a few vents on two other sides
 |
 |
| Here's where some differences show up: The S12-600 (and
500) on the left has smaller and fewer vents all around compared to the
S12-430 on the right, and the output cables are positioned so that they
exit on the side closest to the motherboard when installed in a typical
ATX case. Most users would say this cable positioning is better for cable
management. |
For the record, here's the label from the S12-500. The one on the 600 is
identical except for the particulars.

Feature Highlights of the Seasonic S12-430
|
| FEATURE & BRIEF |
COMMENT |
|
Complies with Intel ATX12V v2.0
|
Supports the latest
motherboards and processors. |
|
S2FC Smart & Silent Fan Control
|
If it is unchanged from the Rev. A3 Super Tornado, it is about the best fan controller we've seen in a PSU. We'll see. |
|
Active PFC environment friendly technology
|
Almost every Seasonic we've looked at has had it for three years; now more common. |
| Universal Free Input:
100-240V |
As in previous Super series, can be useful. |
| Long-lived Aluminum Electrolytic Capacitor |
Not in first batches of the S12; this is part of the new & improved S12. If it means better reliablity, then great. |
|
Forward Converter: Advanced design
|
Instead of a half-bridge rectifier, apparently. |
| Dual 12V
rails for CPU and peripherals |
Specified by ATX12V v2.0 |
| 20+4 Pin Main Connector: Switches back and forth easily from 20 pin to 24 pin. |
One less bit of cable clutter, and reduced contact resistance as a 24-to-20 pin adapter is not used. |
| Short circuit, over voltage & over power protection |
Very nice. |
|
Supports SLI / PCI Express
|
Dual PCIe 6-pin for high power VGA. Earlier versions had just one. |
| Supports Dual CPU motherboard |
8-pin 12V cable |
| Safety / EMI Approvals: CE / TUV EN60950 / UL60950 / CSA / FCC / NEMKO
|
Generally,
the more the better. |

Note that the combined maximum power rating is the only significant difference between the the 500 and 600 models. The individual rail differences are almost insignificant ? just 36W more for the 12V lines. It may be interesting to closely examine the output specs for the S12-430. Here, the 12V lines are significantly lower, but while the +3.3 and +5V individual lines are the same 30A as in the bigger models, the combined maximum for those lines is significantly lower too.
