<p dir="ltr">I've never used the 5v rail on its own, but I've used the 12v rail for various things. They do make great high amperage supplies. You have to short the green wire in the main 24 pin connector with one of the many black ground wires and then it'll turn on. </p>

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><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 <a href="tel:%2B1-204-339-8331" value="+12043398331" target="_blank">+1-204-339-8331</a>, <a href="tel:%2B1-204-515-1701" value="+12045151701" target="_blank">+1-204-515-1701</a>, <a href="tel:%2B1-204-515-1700" value="+12045151700" target="_blank">+1-204-515-1700</a>, <a href="tel:%2B1-810-471-4600" value="+18104714600" target="_blank">+1-810-471-4600</a>, <a href="tel:%2B1-909-361-6005" value="+19093616005" target="_blank">+1-909-361-6005</a><br></span></font><br></div></div></div></div></div></div></div></div></div>

for its +5v out? I have a project and I just need 5v with a beefy amount<br>
of amps, and I have lots of AT PS's around that would fit the bill, but<br>
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>
