Seasonic S12-500 & S12-600 Power Supplies

PHYSICAL DETAILS

Opening up the either the S12-600 or S12-500, one is greeted with an impressively large pair of unique heatsinks. They are both dense and quite large, with a double row of fins. They resemble teeth on a coarse comb. The basic design originated in the Super Tornado; it is a clever way to maximize cooling surface area in the reduced height available to components due to the 1" depth of the 12cm fan.

Big HS fins reminiscent of teeth on a coarse comb.

Side view show components tucked under HS fins.

The other side is where the cables are terminated.

This 7-blade medium-speed ADDA fan has replaced a 5-blade Yate Loon 120mm fan used in earlier versions of the S12-500 & 600.

As with the S12-430, cabling on the 500 and 600 is twisted to minimize EMI.

All the output cables are twisted for reduced EMI.

There are a total of nine cable sets. The main ATX cable seems a bit on the short side at 16", but it should reach most motherboards in most cases.

• 16" cable for main 20+4 pin ATX connector.
• 26" cable with two 6-pin PCIe video / SLI connectors
• 18" auxiliary 12V connector
• 19" auxiliary 4x12V connector (for dual CPU boards)
• 33" cable with three 4-pin IDE drive connectors and one floppy drive power connector
• 27" cable with two 4-pin IDE drive connectors and one floppy drive power connector
• 2 x 24" cables with two SATA drive connectors each
• 21" cable with 3-pin PSU fan speed monitor connector for motherboard

Easy-off 4-pin connector.
