Just use a suitable power resistor (power resistor means it won't fry into a molten lump) on the +12V line. In the absence of info on the PS label, I'd go for loading the +12V line with about 10% of its maximum power/amps. Use V = IR and P = IV to do the algebra to get the right resistance (ohms).<br> <br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small;color:rgb(0,0,0)">Also, along the lines of Adam's reply, you might have to signal back to the PS (by closing a circuit?) that "this motherboard likes you" - otherwise the PS might cut out.<br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small;color:rgb(0,0,0)"> <br></div><div class="gmail_extra"><div><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><font size="2"><span style="font-family:verdana,sans-serif">Hartmut W Sager - Tel +1-204-339-8331, +1-204-515-1701, +1-204-515-1700, +1-810-471-4600, +1-909-361-6005<br></span></font><br></div></div></div></div></div></div></div></div></div>

I'm wondering if running a computer PS just for its 5v line might damage<br>
it somehow? There would be no load on the 12v (and other) lines.<br>
Anything I should worry about?<br>

Thanks!<br>
