The majority of power supply units that sport 80+ certification only comply with the basic or Bronze requirements of that standard. The Silver certificate is downright unpopular. The number of 80+Silver products on the official list is only half of the 80+Gold ones and about one fifth of the 80+Bronze ones.
There is, however, one more category of 80+ products which are even rarer than the Silver-certified PSUs. They are referred to as Platinum. We, at X-bit labs, have never had any of them for us to test although they already number over half a hundred. This is not a big number, though, if you consider that the Platinum requirements were introduced over two years ago, in October 2009.
So, today I’m pleased to review one of the most expected Platinum-certified PSUs of this season: Seasonic SS-1000XP Active PFC F3. It is the more powerful model of the two Platinum-certified PSUs that Seasonic offers (its junior cousin has a wattage rating of 860 watts and provides only four 6+2-pin graphics card connectors; its +12V load capacity is lower by 12 amperes, too).
Click the following link for a description of our testing methodology and equipment and a brief explanation of what the specified and tested parameters of power supplies mean: X-bit Labs Presents: Power Supply Units Testing Methodology. If you feel overwhelmed with the numbers and terms this review abounds in, refer to the Methodology.
You can also go to our Cases/PSU section to check out reviews of all other PSU models we have tested in our labs.
We will mark the actual power consumption of three system configurations (discussed in our article PC Power Consumption: How Many Watts Do We Need?) in the cross-load diagrams. This will help you see if the tested PSU can meet the requirements of a real-life PC.
Closer Look at Seasonic SS-1000XP Active PFC F3
The most technologically advanced product in Seasonic’s line-up deserves special packaging.
The PSU is shipped in a bulky cardboard box with a shimmering holographic 80+Platinum logo. The shape and, in fact, the contents of the box are familiar to us after our tests of the Seasonic X Gold series.
Although it is still just a cardboard box rather than something completely original, it is certainly eye-catching. Unfortunately, it lacks a handle.
The PSU is wrapped up in protective material. The box also contains a pouch with a mains cord and power cables, a user manual and a pack with various small things.
The PSU is snugly packed into a black velvety pouch with manufacturer’s logo.
The cable pouch has two separate compartments that can be attached to each other with Velcro fasteners (there is a mains cord in between them in the photo).
The accessories include three cable straps with Seasonic logo, a few single-use plastic straps, a “Power by Seasonic” sticker, and a set of screws for fastening the PSU inside your system case.
