Re: PSU advice for a mini ITX Asus-H87I-Plus + i5 4590T + 2

It is hard to find anything 80+ rated lower than 300 watts. pico's are good if you can find a good brick to feed them. I picked up a Seasonic SS-300TGW last time I needed a power supply for a low power system. 80+ gold rated not that the extra efficiency of gold over bronze will matter much on a 60 ...

Unfortunately what you ask for isn't cheap. You can abandon your 6 watt limit and go itx with something like ...

The concern with the 7v trick is that you are sinking current into a circuit that is designed to source current.

However, as long as the rest of your system is drawing more current off the 5V rail than your fans, you are likely to be fine.

Your supply has more than enough "watts". My only concern is shared above about the capacity of your 12V rail as your am2 system will be drawing most of the 120ish watts that system will draw at peak from its 12v line. I would suggest you check the label and see if the 12v rail is rated at 10 amps. ...

Your basic home pc draws between 80 and 120 watts. A 17 inch crt monitor about the same. A LCD a fraction of that.
