Setting up an AI computer is safe. Maybe you trip a circut. Maybe you interfere with something else running on your hobby computer. But nothing bad can really happen.&lt;p&gt;Residential electrical is dangerous. Maybe you electrocute yourself. Maybe you cause a fire 5 years down the line. Maybe you cause a fire for the next owner because you didn&amp;#x27;t know to protect the wire with a metal plate so they drill into it.&lt;p&gt;Having said that, 2 4090s will run you aroud $5,000, not counting any of the surrounding system. At that cost point, hireing an electritian would not be that big of an expense relativly speaking.&lt;p&gt;Also, if you are at the point where you need to add a circut for power, you might need to seriously consider cooling, which could potentially be another side quest.</text><parent_chain><item><author>tcdent</author><text>I can&amp;#x27;t believe a group of engineers are so afraid of residential power.&lt;p&gt;It is not expensive, nor is it highly technical.

Read a quick howto, cruise into Home Depot and grab some legos off the shelf. Far easier to figure out than executing &amp;quot;hello world&amp;quot; without domain expertise.&lt;p&gt;The instinct to not touch something that you don&amp;#x27;t yet deeply understand is very much an engineer&amp;#x27;s instinct. Any engineer worthy of the title has often spent weeks carefully designing a system to take care of the hundreds of edge cases that weren&amp;#x27;t apparent at a quick glance. Once you&amp;#x27;ve done that once (much less dozens of times) you have a healthy respect for the complexity that usually lurks below the surface, and you&amp;#x27;re loathe to confidently insert yourself confidently into an unfamiliar domain that has a whole engineering discipline dedicated to it. You understand that those engineers are employed full time for a reason.&lt;p&gt;The attitude you describe is one that&amp;#x27;s useful in a lot of cases and may even be correct for this particular application (though I&amp;#x27;m personally leery of it), but if confidently injecting yourself into territory you don&amp;#x27;t know well is what being an &amp;quot;engineer&amp;quot; means to you, that&amp;#x27;s a sad commentary on the state of software engineering today.</text><parent_chain><item><author>tcdent</author><text>I can&amp;#x27;t believe a group of engineers are so afraid of residential power.&lt;p&gt;It is not expensive, nor is it highly technical.
