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.

(Idel @ desktop)
GA-A75-UD4H requires very little power while operating with the AMD A8-3850's
integrated Radeon HD 6550D graphics core. At idle, the system sips a little as
38W! Under CPU-load conditions this figure jumps to 159W. With the IGP stressed
by 3DMark the total power consumption is a modest 133W. Adding a Geforce GTX470
videocard into the mix introduces a significant power overhead, pushing total
system power draw up across the board.
A Flagship Entry Level Motherboard?
If PCSTATS compares the Gigabyte GA-A75-UD4H only against the other AMD
A75 boards we've tested, there's a lot to like... particularly if you have a
need for many USB 3.0 devices. If not, the microATX Gigabyte GA-A75M-UD2H motherboard is $30 cheaper and a
better buy given the performance restrictions inherent with an AMD Fusion CPU.
In any case, the Gigabyte GA-A75-UD4H offers up strong mix
of features the typical computer user will need. The AMD A75 platform proves
itself well suited to media-center and HTPC tasks; making it very simple to
output movies via HDMI cable to an HDTV for example. The Radeon HD 6550D IGP at
the heart of the AMD A8-3850 CPU supports light DX11 gaming at modest
resolutions, HDMI 1.3 output and typical media playback with ease.
Since there is no support for Nvidia SLI or AMD
Crossfire, this motherboard is best used in standard office computers or family
PCs where budgets are limited and applications aren't too intensive (ie. email,
web surfing, Word, Photoshop, etc.). Given that the GA-A75-UD4H retails for
about $130 CDN ($130 USD, £55 GBP), it just goes to show you how economical an
AMD A75 platform can be.
In the motherboard and IGP benchmarks PCSTATS has shown
you what to expect from the AMD A75 platform and the Radeon HD 6550D integrated
graphics core. As you've seen, it's adequate but anemic. Considered within the
class of entry-level motherboards the Gigabyte GA-A75-UD4H is a very well
equipped motherboard. It comes packed with plenty of connectivity and a strong
focus on build quality. If you really need all that USB 3.0, go for it! If not,
save a few dollars and look towards the Gigabyte GA-A75M-UD2H motherboard instead.
