The question is, can it be possible to use 2 w. Joined Mar 15, Messages 3, 1. Joined Jun 7, Messages 0. Joined Apr 12, Messages 1, 0. I highly recommend experimenting with this for the sake of learning about electronics remember, smoke is bad.
If you just want more juice for your computer, I suggest you keep both power supplies isolated, or even simpler, get a more powerful unit. I've been using 2 power supplies on more than one computer for over 4 years. One runs fans, optical drives and half or more of my HDD's, the other runs mobo and graphics.
Neither one ever breaks a sweat. Multiple power supplies will mean that there are two ground connections. This may increase the risk of creating ground loops in various circuits of the power supply units. Ground loops could also become a problem if you power different parts of the PC with different power supplies, as these circuits would need a common ground or voltage rail in order to talk although, not if optical transfer or DC-DC isolating converters are used.
Find a comfortable spot to safely mount it if possible. Run your extra power to the devices you want extra power for, hook up your power to both PSU's and turn on PC.

Asked 7 years, 11 months ago. How would I set that up? Also, yes, I know it's sketchy, and no, I can't do anything about it. May 31, 1 10, But nothing - and I mean nothing - should be connected to both PSUs. Rogue Leader It's a trap!

To make it even sketchier and cheaper, you could just bridge the green conector with a black one on the second PSU, which will force a permanent ON state.
Then, just switch off the PSU from its own switch. Cheap generic PSUs are a great cheap source of stable, high current 5V energy. Oct 30, 32, 9 99, 4, Two small PSUs is not wise as small size usually indicates low quality.
I've already looked at add2psu and I'm kind of on a tight budget, so it isn't really an option. But the power supply is only w, so I need to upgrade it. Here's the catch: I must use the old PSU as well because all of the connectors on the motherboard are proprietary. Well then any type pre-made device is outta the question. You'd need a circuit diagram to work out what two wires you'd have to tap to relay the ON signal to the 2nd PSU The only catch is that you would have to turn on and off the second psu manually.
But I guess that the HK cheap part is even less safe than my method. I insist with the bridge method not because it is the best, of course it isn't. But given the choice between a cheap unknown part and in the bridge method where you know exactly what is going on and there are no 'hidden' risks, I'll choose the bridge.
It's only a high impedance control signal 5v , negligible current. Just isolate the bridge so that it doesn't short anywhere. Do you know some electronics, or know a friend who does?
Unfortunately not, however I found a UK based guy who makes them for a tenner on eBay. I think I'll go for that. When it senses power is applied, a relay engages the power pins on the second power supply. This is incredibly handy for use with three or more power supplies in much larger rigs 12 GPU rigs. You can plug as many of these into your main power supply as you have SATA ports available, and then plug the rest of the power supplies into the ATX headers on the the sync modules.
Pretty sweet idea! These modules are safe and effective, but be sure to read our risk section below before using them! You can pick these up here for cheap! Using dual power supplies for mining is not without some risks. But they can be completely mitigated if wire them correctly. All it takes is a little learning. The problem is that the power between the to power supplies is not isolated. This can be very problematic for circuitry in your computer, especially if the power is out of phase.
If you have dual power supplies plugged into different outlets in your house, they may be on a different phasing from your breaker panel. To safely wire dual power supplies in a mining rig you need to wire them such that the components are electrically isolated and that only signalling is passing between the two. To solve for this you need to make sure components only receive power from one power supply.
On power supply two, make sure the VGA power connector and riser power both come form the same power supply. Never plug the riser into power supply one, and the GPU into power supply two. Try as much as possible to spread the load across both power supplies evenly. Mike is the founder of The Geek Pub.
