Fry's Electronics Employee lied about merchandise, sold me an item he knew was not good enough quality, under the guise of "that should be plenty" dallas Texas

If you are advanced enough in computer knowledge that you are constructing your own computer, you need to be able to understand exactly what parts you need and what specifications you require.  Then, you shop for the power supply and other parts that you know will work together.  You don't take the word of and employee who may or may not have all the required spec requirements and may or may not even be qualified to advise you.

If you don't have that level of knowledge, you should just buy a name brand professionally engineered, off-the-shelf computer.

Amazing how you spend over $1000 in parts and don't do enough research to figure out what you may need for power...or you are just clueless.  Or did you just do tons of research for every other part and figured for the power supply you will just take what ever they say?

Did you tell the employee EXACTLY what you would be running, that is the exact specs of every piece of equipment so that they could be fully informed to give you a power supply with the correct wattage.  Or did you just go in and say, hey I have a computer and give me the cheapest one you got because I already spent $1000 and don't have much money left?

Since you were "advised" on-line and by friends did they tell you that the power supply rating is the MAXIMUM output you would get.  That unless it is certified for a certain minimum it is not uncommon to have it only output 75-80% of maximum. 

Nothing you have shown here shows that the employee lied, at least not intentionally.   It actually appears that the only one who may have lied is you.  Because in your title you stated that they did this and knowingly.  Yet the very last line you stated that it COULD be the problem.  So what if it turns out it wasn't?  The best you can do is come back here and post an update..you CAN NOT change the title of the report so anyone who comes and just looks at the title will think they did this.   Just something to think about before you go blasting companies on the Internet.

Oh and don't get me wrong.  I have no idea what your problem is.  It could be the power supply. But the Power supply could have been enough just a bad one..it happens.  It also could be something else...perhaps even an inexperienced DIY computer builder.
