Seasonic
SS-1050XM (X-1050)
Although Seasonic’s XM sub-models appeared
earlier than the KM3 model discussed above, it is still being produced, so we
will go on following our traditional way of assessment to consider PSUs from
lower to higher wattages.
We will not rely on their packaging and
accessories because they are identical to the KM3 PSUs and their predecessors.
Product
packaging
We can only take notice that the packaging
is separate for each product model: the wattage rating is printed right on the
box.
Exterior design
The external differences from the
lower-wattage X series products are not limited to the larger sizes. Instead of
a conventional network of fans we can find a cut-out on the PSU case in which
is covered by a yellow-colored plastic piece attached to the fan. The plastic
sheet bends easily just by pressing with one finger. It has a network of
honeycomb vents that helps define Seasonic’s PSU, but is not comfortable in
terms of sound. It will create more engine noise at high speeds of the fan.

image
There is almost no empty space on the panel
with modular connectors because the increased wattage also means that the
expansion opportunities are wider.
The
image of the front product
Even the observed image of the back product
is different from the other X series models. The external case is surely longer
here while the Power button is also larger.
As a matter of fact, this PSU’s exterior
design, from the plastic details of the fan to the power button and large
modular connectors, is exactly the same as the Seasonic SS-1000XP. However, it
is unmistakable towards the overall style of the X series.
Exterior style
Circuit
design
The interior design is similar to the
Platinum-certified Seasonic we have tested before. Compared with the
Gold-certified models, the SS-1050XM (X-1050) appears to use the elements of
both newer (see above in this review) and older products on a bit of larger
main PCB.
Interior
design
The bottom and the left of the photo are
corresponsive to the new KM3 models: the layout of the heatsinks with a
sub-card in the middle, the filtering chokes, and the input capacitors.
The leftovers from the previously older KM
series PSUs can be found in the upper and right side of the photo: the
low-voltage with small separate heatsinks, and the power connectors.
Interior
design
Therefore, the overall circuit design
compared to the other X series products: the PFC operation and dedicated
voltage regulation based on DC-DC converters.
The
inner parts
As the PSUs have been discussed above, the
SS-1050XM (X-1050) uses an Infineon ICE2QR4765 chip for its standby source. A
Rubycon capacitor is able to be found nearby. The lower-wattage PSUs do not
have the components with such a brand.
The
capacitors
But as in the models discussed above, the
output capacitors are manufactured by United Chemi-Con.
Cables and connectors
All of the SS-1050XM (X-1050) modules are
equipped with the following connectors:
·
Connector for a mainboard power cable
·
One connector for a CPU power cable
·
Four connectors for PCIe power cables (one of which
can be used for a second CPU power cable)
·
Six peripheral power cables
Coming with the
PSU are:
·
A motherboard cable with a 20 +4- pin connector
(61 cm)
·
A CPU power cable with 4 +4- pin connector (65
cm)
·
A CPU power cable with a 8-pin connector (65 cm)
·
Three cables graphics card with two 6 +2- pin
connectors on each (60 cm)
·
Two cables with three PATA power connectors (55
+15 + 15 cm)
·
One cable with two PATA power connectors (35 +15
cm)
·
Three cables with three SATA power connectors on
each (55 +15 +15 cm)
·
One cable with two SATA power connectors (35 +15
cm)
·
An adapter for an electrical connection to a
port PATA floppy-drive (15 cm)
The cable system
is similar to the previous generation of the X series versions with their dual
graphics card cables and large number of PATA power connectors. As for SATA,
the X-1050 only has one more than such a connector compared to the
lower-wattage models mentioned above.
Even so, there is a significant difference
compared with the previous X series products. Their modular cables are mostly
similar (except for the 20 +4- pin motherboard cable and the dual graphics card
cables), but the high-wattage models mentioned above have more prominent
features with more normal round cables coated by nylon.
The selection of cables and connectors is
rather sufficient if considered that such PSUs are to aim to the target market
of the high-end computer configurations, the dual cables are also quite good.
Such computers may include a high-end graphics card with two power connectors,
so there will be no cables without being used inside the computer case.
Technical specifications
Technical
specifications
As for all of the other modern products
from Seasonic, the X-1050 can offer most of their power through the +12 V
voltage range while the load capacity of the other voltage ranges is fairly low
(150 watts is not much for a 1050W PSU).
It stands out with the feature of 80 PLUS
Gold certification.
Contrary to the latest products from
Seasonic, it comes with a 5-year warranty. That is quite long, but the 7-year
warranty period of the KM3 product models is even better.
