Running power supply with just fans
Would it be safe to run a 500W power supply with the only load being 4
12V fans (and a few LED lights) or would this not be sufficient load to operate safely? If not, about how much load should I put on it? |

I don't know why you would want to do that, but a Google search such
as: minimum + load + power + supply - as is, should find links to the information. Eric, PC Buyer Beware! http://www.pcbuyerbeware.co.uk/ |

In article .com,
says... Would it be safe to run a 500W power supply with the only load being 4 12V fans (and a few LED lights) or would this not be sufficient load to operate safely? If not, about how much load should I put on it? AFAIR you need a load on the +5V rail as it is a Switch Mode PSU. -- Conor, Same ****, different day. |

If not, about how much load should I put on it? If you go to the power supply manufacturer's specification, you will see that it has minimum loads specified on outputs, as well as maximum loads. Here's an example: http://www.antec.com/specs/NeoHE380_spe.html In practice, some supply manufacturers build in loads that meet the minimum power requirement. Others only require that one output is loaded - but it may be the 12v, 5v or 3.3v. In general, a load of a few watts (say 5-10) is enough. So one hard disk will be fine as a minumum load. Doesn't even have to be connected to an IDE cable... If your fans are rated at .25A, 4 of them will take around 12W, which should be fine. If they are rated at 0.1A or less, then that is pushing the limit. But they need to be running at full speed, so no speed controller! -- Sue |
