</span>The typical failure mode of these POS bricks is the cap<br>
fails after a few years (heat related, usually), and you<br>
get extremely high ripple voltages. Random stuff then<br>
happens (well, not random, predicable based on the<br>
internal components and design) Observed/Reported<br>
symptoms include (random) resets, and signal lock/quality<br>
issues. If one opens the black POS adapter, you can<br>
usually observe the bulging cap, and even replace it,<br>
if one desires, but obtaining a high quality replacement<br>
even for the cap can sometimes be hard. Easier to<br>
just replace the adapter.<br>
<br>
Personally I automatically replace all my provided POS<br>
supplies with high quality switching supplies from OEMs<br>
such as Delta within days of purchase just because I<br>
like reliable power, but I have an advantage that I can<br>
walk to a local surplus store (and 10 minute drive to<br>
another) that sells them at huge discounts, so I do<br>
not pay the manufacturers retail prices.<br>
<br>
Note that I do not know what availablity you have, but<br>
the D-Link JTA0302B reportedly works (based on<br>
reports of others).<br>
<br>
As I recall, these are the same supplies as used for<br>
BeagleBone Blacks, so you might be able to find a<br>
match based on that.<br>

</blockquote></div><br></div><div class="gmail_extra">Bowing down to those of you with more electrical knowledge, I see that the JTA0302B is a 2A power supply while Silicondust says it needs a 1A. But I do recall seeing people mention the JTA0302B in the 'dust forums.<br><br></div><div class="gmail_extra">Going back to high school science I seem to remember amps are the "amount", while volts are the "presuure" of the power. So what exactly happens if I use 2A on something that calls for 1A?<br><br></div><div class="gmail_extra">Also...going to the D-Link Canada site I can't see power adapters listed at all, while Amazon seems to be selling JTA0302B "compatible" adapters. Any suggestions where I could get the real deal if the 1A/2A thing isn't a deal-breaker?<br><br></div><div class="gmail_extra">Side-note I love how people selling these things will list the V's and the A's but not type the additional characters to tell me if the connector is a 2.1mm inner-diameter connector, center positive.</div><div class="gmail_extra"><br></div><div class="gmail_extra">And finally, thanks, and wow, what did we do before the internet? Now we can tap into the hive mind and in a matter of hours have advice and education from all over North America, Europe and beyond and not just the spoon-fed info from companies.<br></div></div>
