Product interior showcase
On the top side, we can see a 135 mm FDB Fan. It is a HA13525H12F-Z, made by Hong Hua, with revs up to 2000 rpm, and it’s 25 mm thick. Seasonic’s PSUs are built with 100% Japanese, 105℃ capacitors, providing the highest reliability, and that’s the reason why they offered a 10-year warranty. Without cables, the unit weighs 1.61 kg.
Inside, there are only high-end Japanese capacitors certified for 105°C. The interior looks more like a Focus series, not a Prime. The soldering quality is really nice. There is also an NTC thermistor and a corresponding bypass relay for enhanced inrush current protection. The APFC MOSFET is an Infineon IPA50R190CE, with a Champion CM6901T6X resonant controller. For the PFC, there is a Champion CM6500UNX controller.
On the secondary side, you’ll see a Weltrend WT7527V supervisor IC.
In the Connect module, you can see the PWM controller, an ANPEC APW7159C. Additionally, there’s an extra over-temperature protection circuit.
Seasonic company is known for its great power supplies, including the Focus (available both in ATX and factor), Prime (with the 80 Plus certificate up to Titanium), or Connect series. Speaking of the last one, they’ve gone further by introducing a chassis containing this piece of hardware – it’s a Seasonic SYNCRO Q704. But that’s not all – according to the marketing information, it really fits together, literally and figuratively.
