Got any more pics? Also what was the deal with the 5v having the same load as the 12v? I just used one 430watt psu today to power a Pioneer DEH-P7300 and it was working great at full volume... But we also have access to a crap load of old 230watt psu I was thinking of mounting in a box and replacing all the small guage wires with 8ga and then out to a bananna plug setup... </font>[/QUOTE]You dont want to put the same load on the 5v line as the 12v line.. you'll want to put the max load that the ps is rated for on the 5v line. you can find this on the label. just remember that 1 ohm at 1 volt draws 1 amp. so 1 ohm at 5 volts draws 5 amps, .5 ohm 10 amps, and so on.. and make sure to use resistors of 10 watts or higher. i use 25 watt ones, but the 10 watt will do the job fine, just a little warmer. You dont want to replace all the little wires with an 8 gauge.. i doubt you'll find a spot big enough on the board to drill a hole big enough for the 8 gauge and still have enough left of the circuit board to carry the current. I've just used all of the little wires, soldered them together at the end, and attached them to 2 pairs of huge binding posts on the front of my case. I then run 8 gauge from there to the amps. You dont have to worry about fusing your wires with the computer power supplies, if there's a short circuit, or too much current draw, it will automatically shut off until power is shut off and then turned back on.

So you have 160A @ 12V? Plus ontop of that you have your 5V lines current maxed out which is probably close to 300A (most comp power supplies i've seen the 5V line can use twice'ish the current as the 12V line)

How do you have this wired into you house?

Only reason I ask is:

(160*12) + (5*300ish) = 3500Watts
3500/110 = 30A'ish


So the only reason i'm asking is do you have yours hooked up too a 220V outlet or do you have extension cords running to different breakers throughout your house?

Not trying to sound like a dink, just curious how you have everything wired up.

my room is wired up with 4 circuits for the outlets, that's the beauty of finishing you own basement [img]smile.gif[/img] there's 2 outlets per wall, and each wall shares a circuit with one outlet of the next wall around the room. anywho, there's 2 power cords coming out the back.. i can plug one in, or two in, depending on what i need. most of the time, i only use 1, and the loads are switchable on some of the power supplies, so i'm only drawing what current i need [img]smile.gif[/img] it all makes sense in my head, but i'm not sure i'm doing a very good job of explaining it :)The power supply i built is total overkill [img]smile.gif[/img] i'm thinking maybe i should size down [img]smile.gif[/img] project for this weekend i guess.

Ok, I guess I do not understand why you want to do this to the 5v line? Gonna e-mail enermax and see what they say..

well without a load on the 5v line, the voltage on the 12v side is around 10 or 11 volts [img]smile.gif[/img]

What about using something like this?

Power Supply Load Resistor

you could.. but you'd waste alot of money. look on ebay, you can get 5 ohm 10 watt resistors in packs of 25 for a couple of dollars. i got 1 ohm 25 watt ones off ebay, in a pack of 50 for $6+ shipping :)thoose load resistors you had the link for there only draw 1 amp each [img]smile.gif[/img]

But I really only need to hit the minimal 5v load to make it work... that will keep the voltage regulated I do not need it to go crazy...

OH my god.. You guys are going to start a fire.

First off, an old receiver from a pawn shop for $100 is going to have less noise and sound better than what you need to spend on a power supply.

The little Pyramid supply is an OK unit, and it's nice that you can crank up the voltage.

If you are going to beat on the system, then you are going to need a real power supply like the ones I use:
The Cascade Audio APS-90.

You can use a car battery, just find a way to vent the explosive and dangerous gases out of your room so you don't die...

You can also pick up an inexpensive stand-alone 120V amp like these if you want to save yourself the potential house-fire and insurance headaches...

YES, someone addressed my question.

i use this exact same power supply on the test bench at work.

i ran a Phoenix Gold M100 on a pair of cerwin tens and the little power supply did quite nicely.

i think it will do quite well for my application, and it is definately much safer and more attractive that some f those pics..lol.

if only i could debadge it.
