Compatibility check before ordering

Verify that the original part number matches the SS-400ET exactly or confirm compatibility with the manufacturer. Ensure the system uses an AT-type power supply and that the motherboard accepts the ATX12V V2.2 connector layout.

商品問答

Does the Seasonic SS-400ET box include mounting screws and power cables?

The power supply is supplied as a standalone unit. Mounting screws and power cables are not included and must be sourced separately.

How does the 400W capacity relate to the 80 Plus Bronze rating?

The 400W figure is the maximum continuous output. The 80 Plus Bronze certification confirms at least 80% efficiency at typical loads, reducing waste heat.

What does the ATX12V V2.2 label mean for my motherboard?

ATX12V V2.2 indicates the unit provides a 24-pin main connector and the 12V rail distribution required by motherboards built to that specification.
