Seasonic Focus SPX (2021) 80 PLUS Platinum SFX

Seasonic hat sein Portfolio an kompakten Netzteilen im SFX-Formfaktor um ein weitere Modellreihe erweitert. Die Focus SPX Series mit 80 PLUS Platinum ergänzt die Focus SGX mit 80 PLUS Gold um zwei effizientere Alternativen. Zur Ausstattung gehören wieder ein voll-modulares Kabelmanagement und eine semi-passive Lüftersteuerung. Ob das Seasonic Focus SPX 750W das Potenzial hat, sich mit Corsairs Platzhirsch "SF Series" anzulegen, haben wir uns natürlich einmal näher angeschaut.

After the SFX-L form factor SGX units, Seasonic updated its small form factor offerings with the new SPX and SGX lines following the SFX form factor. The first includes two models with 750 W and 650 W maximum output, while the latter has three members with capacities ranging from 550 W to 750 W maximum output. In today's review, I evaluated the flagship Seasonic SFX offering. I compared it with the best SFX units available today, including the Corsair SF750 Platinum, which holds the performance crown in this category. Despite Seasonic's experience in designing PSUs, the SF750 Platinum created by Great Wall in cooperation with Corsair is the far better overall performer. That said, the SPX-750 has better transient response at +12 V, which is of immense importance, and a longer warranty. It also registers much higher efficiency with 2% load since the SF750 is based on an older design, so the SF750 isn't compatible with the newer ATX requirements.
