Seasonic SSR-360GP (G-360)
Package and Accessories
The packaging of this PSU was somewhat spoiled by an accident in our test labs, but the product itself survived.
Compared to Seasonic’s top-end PSU series, the packaging looks plain, lacking gold elements or shiny logotypes. You can make out a stylized letter G on the front of the box. That’s the letter Seasonic has decided to use to refer to its newest Gold-certified PSUs.
The numerous advantages of the product the manufacturer wants us to be aware of are listed on the back. We’d single out the following: DC-DC converters, tight voltage regulation (the output voltages only vary within 3% of the required levels), and a 5-year warranty. Coupled with the Gold-certified efficiency, that’s quite a lot of advantages for a PSU cheaper than $100 and produced under a leading brand.
The accessories are the same as included with more advanced Seasonic PSUs except that the user manual is designed and printed in a simpler way.
Of course, the affordable series is not decorated as gorgeously as its more expensive counterpart. For example, we can see paper labels here instead of painting. However, we can easily identify the manufacturer by the PSU’s external features. The sunken fan grid with large honeycomb-shaped cells is exactly like the one you can see in Seasonic’s more expensive Gold- and Platinum-certified series, even though this grid covers an ordinary-looking fan rather than a characteristically shaped and individually balanced Sanyo Denki.
There’s no difference from top-end products on the back except for the color of the sticker with manufacturer logo.
The PSU housing consists of two parts: the bottom panel together with front and back panels and the cover with side panels. The more intricate design of the top-end PSUs is not implemented in this inexpensive product for the sake of lower cost.
It is a new platform indeed. We haven’t yet seen a PSU with such an interior.
On the other hand, the overall circuit design is quite typical for a modern PSU. The Seasonic SSR-360GP features active power factor correction, uses DC-DC converters to produce +3.3 and +5 volts, and has very small heatsinks.
The main PCB only carries a standby source chip Infineon ICE2QR4765. Its PWM/PFC controller and supervisor chips are located on a long daughter card near the front panel of the case.
The DC-DC converters reside on another daughter card you can see near the output circuitry and capacitors.
There are United Chemi-Con capacitors at the output.
The Seasonic SSR-360GP also uses Rubycon capacitors elsewhere and has a large blue Hitachi AIC, rated for temperatures up to 105°C, at the input. So, the promise of all-Japanese capacitors is true.
Cables and Connectors
The Seasonic SSR-360GP is equipped with the following cables and connectors:
- One mainboard cable with a 24-pin connector (54 cm)
- One CPU cable with a 4+4-pin connector (57 cm)
- One graphics card cable with a 6-pin connector (60 cm)
- One cable with three PATA power connectors (45+12+12 cm)
- One cable with two SATA power connectors (44+15 cm)
- One cable with two SATA power connectors (36+15 cm)
Included with the PSU is a 15cm Y-shaped adapter from one PATA power connector to two floppy-drive plugs.
The number of connectors is impressive for a PSU of such a modest wattage. The 4+4-pin CPU plug is quite a rare thing to see in products of this class, let alone the dedicated graphics card connector.
We can only find fault with the SATA power connectors which may turn out to be too few for some PC configurations. You cannot connect more than two HDDs (if you’ve got an optical drive) unless you use power adapters. Most users won’t notice this problem, but anyway.
The relatively short CPU power cable is hardly a downside since this PSU is likely to be used in a mATX or ATX case where that cable will be long enough to be hidden behind the mainboard.
