2 questions. First would be is there any fire hazard to this? Basicaly just the fact that the PSU is not attached inside a case and just hanging out. If say it was on the rug or something of that sort like your picture shows. Would that not be at risk of fire? The heat from the PSU to the carpet perhaps. Or say the 20 pin wire fell to the carpet with that jumper wire hanging out, it couldn't cause a fire?

My second question would be, what would be the best way to connect this PSU to your equipment inside the case? Stick the wires through an empty PCI slot? I would think that might hurt your air cooling flow. Though I don't see where else to put it, so it does not look like crap, and have a wire hanging out of some odd spot(FDD bay?) heh.

Well some cases actually have a spot for a second PSU. Most do not though. I personally had mine sitting in the location below my hard drives using your PCI slot method. Case temps were very high in that config. I am not running two PSUs at the moment, but I used the same method to create my UV pen mod FAQ. I needed it to run the UV lights to show off the pen mod. I think leaving it on the carpet would be fine. PSUs dont usuallu run too hot to touch. And as for the staple, I touched it and it wasn't even warm. I think it is very small amount of voltage.

I would suggest running it outside the case for better cooling. Maybe on top or under it?? Get creative. I am sure you can find a place for it.

Alright, so I got this 300 watt power supply hooked up along with a 500 watt power supply. I've got a Radeon 800xt that requires two power supplies, one from the AGP slot and one from the power supply. Was wondering if anyone would think its a bad idea to have both power supplies hooked up to it. . meaning one to the motherboard that supplies power to the AGP slot and the other PSU supplying power to the GPU via the power input? Can I fry my card?

**SpookedJunglist** · 12-27-05

I would recomend powering your GPU and CPU on the 500 watt. And all other peripherals off of the 300watt. That way they get clean power. And drives dont usually care about voltage fluctuation.

I must say this not only works on the intended application, but it makes a very cheap and powerfull power supply for a DC charger that I use on my Radio control hobby.

Yeah i have a little 250W rigged up to a knife switch works great i scraped the 20 pin connector tho

Thanks for this - I had a 450w PSU laying around and followed your guide now i have it powering my fans and my lighting.

I had 2 other psu before, but they were fried before i even tried to use them, i just used this guide to test them to see if they were really dead.

First I'll thank all you guys for all the good ideas!

I'm bilding a extremly compact DesktopPC based on the D.Vine5 case with a Athlon64 FX-60, 2x512MB OCZ PC5000, 2x WD Raptor 74GB, 8x 400GB, 1x DVD-Burner, 1x ATI X800XT, 1x ATI X1900XTX. The big issue here is the power, so I'm making a custom backside so I have 125mm (H) x 90mm (W) x 250mm (D) space for powersupplies, but does anybody have any good ideas how so solve this?

Anyone know how to do this with an AT-Style Power Supply???

The silverstone 7 is made for this purpose 2 psu slots are better than 1. I never much cared for redundant power myself, so it just made since to put something in the second slot just to power the quad sli. The Silverstone 7 even includes all the hardware nescessary to make the dual psu work. One problem some people my have with the siverstone 7 is if your psu has short wires you may not be able to connect to the mobo since the psu slots are in the bottom of the case.
