Tsunami Extreme AX400-PN (350W) and AX450-PN (400W)
The model names indicate a relation to the above-discussed Tsunami Hercules AX400-PN.
Indeed, they only differ externally with the color of the paint. The Hercules is gray while the Extreme is black.
The internal design is identical. That’s the well-known FSP ATX-xxxPN series. Tsunami declares the peak output power in the model name while FSP, the continuous one. Thus, the Extreme AX450-PN is based on the FSP ATX-400PN while the Extreme AX400-PN is based on the FSP ATX-350PN.
These two PSUs being identical in most of their parameters and internal design, I will be discussing them both together here.
They comply with the ATX12V 2.0 standard, their labels specifying not only the peak but also the top continuous output power. The PSU can yield just half a hundred watts less on the +12V rail (split into two “virtual” output lines) than its total output power.
The PSUs have the following cables and connectors:
- Mainboard cable with a 20+4 connector (35cm in the AX400-PN and 40cm in the AX450-PN)
- CPU cable with a 4-pin connector (31cm)
- Graphics card cable with a 6-pin connector (36cm)
- Cable with two Molex connectors and one mini-plug for a floppy drive (27+15+14cm)
- One cable with two Molex connectors (41+15cm)
- (In the AX450-PN only) one cable with two Molex connectors (26+14cm)
- (In the AX400-PN only) one cable with one SATA power connector (41cm)
- (In the AX450-Pn only) one cable with two SATA power connectors (31+10cm)
It’s easy to guess my criticism here. There are too few SATA connectors (only one in the junior model and two on the same cable in the senior one). The cables are also rather short.
