Seasonic AI Replacement Unit

This power supply serves as a direct replacement for Seasonic AI series units rated at 1000W and 850W. It fits standard ATX bays and targets builders or technicians who need a compatible spare for those specific models. The new condition ensures full service life from first installation.

80 PLUS Gold Efficiency

The unit carries 80 PLUS Gold certification, confirming high efficiency across typical load ranges. Lower energy waste translates into reduced heat output and quieter cooling behaviour. This specification is the primary indicator that the part meets modern efficiency expectations for a replacement PSU.

1000W and 850W Headroom

Rated outputs of 1000W and 850W give ample headroom for high-end graphics cards and multi-drive arrays under sustained load. Zero RPM fan mode keeps the system near-silent at low and medium loads, while the resonant LLC topology with DC-to-DC conversion maintains clean power delivery. Builds requiring higher peak wattage or non-Seasonic form factors will need a different unit.

Questions about this item

What does the 1000W rating actually deliver inside a built PC?

The unit can supply up to 1000 watts of continuous power to components through its ATX connectors, with 80 PLUS Gold efficiency reducing waste heat.

Which ATX standard does the SSP-1000RS follow and what limits does that set?

It uses the ATX form factor, so it fits standard ATX cases and provides the usual 24-pin, EPS and PCIe connectors defined by that specification.

What clearance and mounting points does the PSU need in the chassis?

The ATX dimensions mean it mounts with four rear screws in any standard ATX bay and requires typical depth clearance for cables.
