Power Jitter Observations -
Voltage jitter is read by
accessing the power options displayed in the motherboard BIOS, with the system obviously in an unloaded state. *All
voltages were read from the BIOS of an MSI K8N Neo4 Platinum SLI
The voltage readings from
the motherboard are very solid indeed and the Seasonic S12 600 does very well
Power Jitter Observations -
Voltage jitter was read by a Mastech MS8230B Multimeter with the system in an
unloaded state. During testing the power supply is was still connected to a full
computer and voltage values.
It's funny to see the voltage differences between a
multimeter and BIOS readings. The voltages as read through the multimeter were
solid and did not move one bit during testing.
When looking at the Seasonic Power Supply test results we see two values,
wattage and volt-amps. Since it might not be clear what they measure, here's a
volt-amp (VA) value is how much real power is being consumed by the power supply
being tested to provide the wattage (W) value. The higher the VA value is, the
more electricity is being used by the power supply. Because no electrical device
is 100% efficient, there will always be some loss when converting AC to DC. The
closer the volt-amps and wattage figures are to each other, the more efficient a
power supply is. This is called the Power Factor: wattage / volt-amps =
Since we're testing with a 120W dummy load, the
load on the power supply (wattage) should be as close to this figure as
possible. Anything above this load in apparent power describes the overhead and
wasted energy (given off as heat) for the particular power supply being tested.
For the unloaded tests, the wattage and volt-amp figures should be as close as
possible to one another. The lower the figures are, the less power is being
Measurements were taken with the Extech 380803 Power Analyzer.

Seasonic S12 600 is definitely very efficient in converting AC to DC and does
not waste much power as heat requiring only 164W of energy to power the
120W dummy power load.
Hello Mr. Efficient
With power requirements of
high end systems climbing ever higher, enthusiasts and manufacturers have been putting more emphasis on higher quality power supplies. While this has increased prices slightly, consumers are equipping PCs with better power supplies now and that is a good thing.
There are a lot of expensive power supplies on the market but unfortunately most are expensive due to gimmicks like flashy LED fans, see through PSU containers and detachable cables. What you should look for instead is for a power supply that has passed industry certification (like nVIDIA's SLI certified PSUs) and do your homework by posting in computer forums asking the more experienced users what they think of certain models. This way you can get yourself a truly reliable power supply, not some pretty piece of junk.
Seasonic has swept through the enthusiast community pretty quickly and for good reasons too. Its 30 years of experience manufacturing power supplies means Seasonic knows how to deliver the goods and that's exactly what has made the brand so popular. Simply put, Seasonic power supplies are rock solid and give even the most hardcore users great peace of mind.
The new flagship Seasonic S12 600 has a high standard to live up to but as you saw it had no problems. While reading the specs listed on the Seasonic power supply might not seem as impressive as other models available, please keep in mind that they are sustained which means the Seasonic S12 600 can deliver a true 600W of power while under load and not just during peak times.
The performance of the Seasonic S12 600 was excellent as
expected from a Seasonic power supply. With a retail price of $171 CDN ($155 US, £83 GBP) , the Seasonic S12 600 is expensive but compared to other power supply's in that price range offers you better value.
If you're looking for a new power supply for that hot rod system of yours, make sure you check out what Seasonic and the S12 600 has to offer. You'll definitely be impressed as has everyone who has used a Seasonic power supply.
