Seasonic S12G-750 Power Supply Review

Rating: 9.0.

Today we look at the latest Seasonic S12G 750W power supply, a new 80 Plus Gold design using top grade Japanese components. This is the highest output model in the new Seasonic range, alongside a 450W, 550W and 650W unit. Seasonic are gunning for the mass market enthusiast audience, aiming at an estimated price around €100. The new S12G range isn’t modular, however Seasonic have achieved an 80 Plus Gold rating, and offer a substantial 5 year warranty with each unit. Is it worth the money?

Seasonic told us that ‘The S12G Series is the newest addition to Seasonic’s families of retail products. The S12G Series is designed to support Intel’s Haswell processors, features standard all in one cabling with more SATA cables and is an affordable solution for a wide range of applications.  It meets the demands of users who are looking for reliable 80 PLUS Gold performance for gaming and overall usage.”

    Nice review guys. However I always end up thinking that it would make for a much better test&review to go for the middle to low-wattage option of such series. To me it seems those in need of multiple 8-pins EPS and “dozens” of PCIe 8/6pins all to often would go for a modular power supply. Just my 2 cents but maybe something to convey over to the manufacturers supplying the goods?

    the only thing working against it is the fact it is not modular – good review, thanks.

    £99.99 for a 80 Plus Gold with those specs is impressive, always like seeing nippon chemi con – never had one of those capacitors fail on me in 20 years 🙂
