I have just bought a new ultra-quiet 400W PSU (Power Supply Unit) from [quietpc.com](http://www.quietpc.com) for my PC.

Being a lazy useless waste of life and space I haven’t investigated whether there are any issues about replacing the PSU. I just bought the thing on a whim.

My question is - will it run everything fine? I ask because I have a vague recollection of powerful bits (like my geforce 3) needing a certain voltage from the PSU.

Also, is there anything important I need to know before I swap the PSUs?  
thanks.

So long as it meets the systems power needs and fits in the space and the connectors are correct (I assume ATX) you should be good to go.

Sure some of you might think this was a posting error, but in truth nothing goes with power supplies like poutine! Nothing!
