Dead Antec Neopower?

Greetings, I have the feeling after reading (belatedly) a number of posts that I may have made a Noobie mistake. I ordered and received a Antec Neopower 480 from ZipZoomFly. After excitedly opening and fondling my new toy, I discovered a dent in the grill work but no apparent damage to the box or packing materials. I plugged in the power supply to two different outlets and had the same result, no fan, hum or any other detectable sign of life. I RMA'd it back to ZipZoomFly. In my own defense, I contacted both Antec and ZipZoomFly prior to sending it back and specifically asked if it was necessary to plug in something to the power supply in order for it to work and was assured that the fan should come on immediately regardless. Antec did send a link to a site showing how to check the fan on a 20 pin connector. However, not wanting to spend money on a 24 to 20 pin adapter and not owning a multi-meter, I then sent it back. I'm in the early stages of building a new machine and have not yet ordered the motherboard so I convinced myself to return it for the dent if nothing else. My question is, why are there no warnings on any of the major power supply company sites or manuals that there must be a load on the power supplies for them to work? I'll be a little more diligent next time :( Comments?
 
All power supplies need to have a load on them to work properly. To be more precise, they need to recieve a "POWER GOOD" signal from the motherboard before powering up. If you just plug in your power supply and flip the switch, you'll have the +5VSB voltage flowing, but nothing else. You can't really conclude that the PSU is dead if you've never plugged anything into it. Manufacturers don't need to label for that, seeing how you didn't really provide all the necessary ingredients for things to work.

The dent isn't cool though, I'd RMA for that.
 
Probably because in most cases we assume you're going to be building a system with it right away. From the info we get, most people end up buying case/PSU last since prices for other products vary so much. ie people wait for prices to get down to a point they're comfortable with and buy. Once they do that then they order the case/PSU.

I'll let our manual writers know though. Shouldn't be too much of an issue to get in future revisions etc.

Thank you for the replies. I appreciate the future update to the manual AntecRep. While I have built a good many systems, I have not used a power supply with as many features as the Antec NeoPower or indeed any PS newer than 5 years old. I simply was unaware of the requirements for putting a load on the supply for it to work as it most definately was not the case for the units I have used in the past. I look forward to receiving the replacement from ZipZoomFly. I do think it strange that your research shows that most builders buy the case and power supply last for the very reasons you mentioned. The prices on most of the other components do fluctuate more rapidly so, I tend to collect the parts that change less frequently first so as to decrease the wait time for final assembly and testing once the other components hit my price point. My initial plan was to purchase the motherboard last but, I may change the sequence in light of this recent development and hopefully any similar problems. Thanks again.
