System Power Draw
measures total system power draw (watts) with the aid of an Extech 380803 AC
Power Analyzer and A-PFC compliant Seasonic SS-760KM power supply. The meter is placed
between the 120V AC outlet and the PC power supply and the computer stressed.
Total system power draw is recorded and compared to the PC's idle state.

Given that that power efficiency
is one of the few remaining ways to differentiate a board, it's not surprising Gigabyte has put
a lot of effort into improving circuit board level build quality and
electrical efficiency. The GA-Z77X-UD4H motherboard adopts Ultra Durable 4 which makes use
of 'Driver MOSFETs' which combine the functions of a driver, high MOSFET and low
MOSFET into one board mounted component.
by the total
system power draw measurements (above), using CPU-IGP graphics is a good way to
save power! At idle the system draws 86W with videocard, 38W on IGP. Likewise, CPU
loaded power draw figures are 161W with VGA and just 109W with IGP! The
big difference in power draw is evident with a run of 3DMark...

A Change to PCSTATS Motherboard
Where-o-where are the benchmarks?
the benchmark system test specs?
assured that PCSTATS wouldn't post a hardware review without benchmarks for you
to look over, however in this review we're testing a different layout; the test
system specs and full benchmark report will follow the
conclusions. The full set of benchmarks are still included, but we're
not commenting on each chart since the majority of readers tell us
they prefer to interpret the data in the charts
themselves. Please drop us a line and let us know if you like, or
hate, this change to our review format?
Conclusion: A Great Everyday Workstation Motherboard
As we mentioned in the first paragraph of this motherboard
review, we really liked what the Gigabyte GA-Z77X-UD4H board brought to the table
- feature wise, build wise, layout wise - you name it, there was little we
weren't satisfied with. A bad button placement here and there and lack of
bundled in USB 3.0 brackets isn't a deal breaker. As you'll see in
the full set of benchmark charts which follow this conclusion on the
next page, the Gigabyte GA-Z77X-UD4H performed well and was easily able to
keep up with competing Intel Z77 platforms.
For example, in BAPCO Sysmark 2012 the GA-Z77X-UD4H achieved an overall score
of 185; the highest of any SNB test platform and just 12points behind the
GA-Z77X-UD5H-WB test platform. In PCMark Vantage the GA-Z77X-UD4H scored 18635.
On the integrated graphics front the Intel LGA1155 platform offers luke warm
3D gaming capabilities. For example, when running on the Intel integrated HD3000
graphics the platform scores just 1896 in 3DMark Vantage, a good
result for Intel graphics, but paltry next to AMDs APUs which repeatedly scored
in the low 5000's.
Overclocking results were acceptable, but not out of this world. This is
mainly due to the rather limited CPU used in PCSTATS' Intel
LGA1155 test platform - you may see better results, it all comes down to
the CPU. Gigabyte certainly outfit the BIOS and board with plenty of
overclocking features for those who want to push their hardware faster and
faster... there are hundreds of voltage settings to be tweaked, voltage
read points and more frequency controls than you can shake a stick at.
To sum up, the LGA1155 Gigabyte GA-Z77X-UD4H motherboard is built around
the Intel Z77 chipset and compatible with 22nm/32nm Intel 3rd/2nd
Generation Core i7/i5/i3 processors, it offers up a great set of
that'll run the mainstream focused user about $160 USD/CDN. If you're frustrated
by the slow PC you currently have and don't want to wait for Intel's
next CPU, 'Haswell', to drop, the Gigabyte GA-Z77X-UD4H is a wonderful
board to consider. Recommended.
