↪ Notes: Decent electrical performance but OTP is either not present or set too high (>200°C ) which is useless. See testing here. 2 year warranty.
Polaris ATX 3.0 PPS-FC-A3
DC-DC
High Power
NO-815
↪ Notes: Fundamentally a Polaris ATX 3.0 refresh. Load regulation is somewhat subpar on the 1050W model.
↪ Notes: Only basic voltage regulation and ripple data found here. Not recommendable due to age; only kept for legacy purposes (still on website.)
↪ Notes: Very similar to the GX III that superseded it.
↪ Notes: Not to be confused with the GX II Gold.
↪ Notes: Ripple suppression, while within the limits for tier A, isn't as good as other units in its class. The OCP trip points need to be reduced on all rails.
↪ Notes: >50mV ripple suppression on 12V.
↪ Notes: Overall performance is not that great despite a capable platform. Platform just needs to be tuned better.
↪ Notes: OTP either not present or set too high per Aris' review. Out-of-spec 3.3V transient response (7%).
↪ Notes: Only one 8-pin PCIe cable! Dual 12VHPWR. Good performance in pre-production sample, but needs fine-tuning. Semi-digital.
↪ Notes: 5V OCP malfunctioned under high temps; CSZ costdown with Chinese caps and inexpensive bridge rectifiers per Aris' testing.
↪ Notes: Not recommended since no proper testing exists, and numerous issues exist with other Segotep units that were tested.
↪ Notes: 5VSB OCP needs tuning (59mV ripple); An EPS cable can fit into a PCIe socket and vice versa, but they're not electrically compatible.
