Well my old PSU has been a bit unstable recently, so I thought I'd take some of the load off it by hooking up a second PSU with the same spec to run 3 fans off.<br />
<br />
Now it seems to be more stable, but my question is, will running this PSU cause a large rise in the electricity bill, even though it only powering 3 fans?<br />
<br />
Sorry for the really crap picture quality, they're taken from my really crap camera phone. <br />
<br />
I'm not worried about cable management either. All these cables are on the outside of the case so it's not a problem for aireflow.<br />
<br />
Also, dunno if you can see it in the picture but I've put my "side" intake on top of a desk tidy. This gives it the added height to cool my passive graphics heatsink and passive northbridge heatsink.<br />
<br />
When I turn the fans power supply off, my NB temp goes up pretty quickly from 20 to 30. I only turn the PSU on when I think I need some cooling <img src="/images/smilies/tongue.gif" border="0" alt="" title="Stick out tounge caps" class="inlineimg" />.<br />
<br />
However, this shouldn't be very often because I rarely play games any more.<br />
<br />
Anyway, if my question could be answered, it'd be nice!<br><a href="http://assets.overclock.net.s3.amazonaws.com/c/c0/c0b6d2f9_vbattach33334.jpeg"><img src="http://www.overclock.net/image/id/616973/width/525/height/525/flags/LL"></a><br><a href="http://assets.overclock.net.s3.amazonaws.com/e/e7/e7952eb1_vbattach33335.jpeg"><img src="http://www.overclock.net/image/id/616972/width/525/height/525/flags/LL"></a><br><a href="http://assets.overclock.net.s3.amazonaws.com/c/cd/cdd62b3d_vbattach33336.jpeg"><img src="http://www.overclock.net/image/id/616971/width/525/height/525/flags/LL"></a>

a PSU will only produce the power it needs.<br />
<br />
say your computer draws 485w and you have a psu rated to produce 750w. your psu will only provide what your computer needs and thus only give out 485w.<br />
<br />
as for electricity bills go... generic PSU's tend to be verry inefficient which means a lot of the current they draw from the wall turns to heat instead of power for yoru PC. You would probably have a lower bill with one high power, high efficiency psu (80% or higher) then you will with the 2 generic, lower power psus
