One PSU, two RIGS?!

[Javier Ewe]

Hey, I'm upgrading my living room PC and allowing it to play games on it, previously it was a C2D E7500, pretty crap.

So, i plan on upgrading it with under 100USD, (live in SG so under 150SGD).

Here it is:

What do you think of it? The X5450 is a Core 2 Quad Q9650 equivalent but it is better binned with the highest quality silicon and thus better overclocks and it's cheap as well. LGA 771 to 775 mod.

Nice that the GTX 670 would come with a pre installed Arctic Accelero Twin Turbo!

Also is it possible to use the 6/8 pin connectors from my 24/7 mining rig (which is why there is such a overkill PSU). My mining rig is currently only using ~650W or so. My main PSU only has one 6 pin. Will anything detrimental to the parts happen if the mining rig suddenly shuts off while i am gaming, must i plug out the 6/8 pin connectors to the mining PSU every time i am done using this PC.

Thanks for your time.

 

TL;DR can i use a power supply from a mining 24/7 rig to power my graphics card in this rig?

I'm confused on what you're trying to do, also RIP night theme users. ATX power supplies are pretty dumb, as long as they are activated and you don't draw too much power from them, they supply constant clean voltage to all of the connectors. For example, I have a CX430 that I use for drone battery charging. I did this by desoldering all the wires and connectors from the board, then attaching my own wires to the 12v rail. One short between the green wire and ground later, and I have 12v 400W~ to use at my disposal. My point is as long as you can trick the power supply into thinking that it's plugged into a motherboard (the green wire thing) it will supply consistent current across all of the rails. So theoretically you could jump the green wire, plug in the GPU plugs, and run your GPU off a different supply.

 

I'm not sure how you would power two rigs off of one supply because ATX supplies only have one 24pin plug, which you need one per rig. I guess you could make a harness with a female 24pin connector that doubles each wire into two male 24pin connectors, or you could make a PCB that does the same thing with one 24pin in and two 24pin outs. However, I'm not sure how that would work if you wanted to run one machine and not the other. 

 

TLDR, just get a second power supply, they're not that expensive.

i meant using 6/8 pins from the power supply in my mining rig (Corsair RM 1050) to power the GTX 670 in my new rig (this xeon one) because the power supply i'm using it with only has one 6 pin and is just crap.

When you copy paste it, press "remove formatting"

 

Or go to color section and press "auto"

Wait color section? Never seen where is that before

Yeah I guess that would work, do you have any molex to 8 pin connectors?

yeh, i have some but i prefer not to overload my crap power supply because it has killed some hard drives presumably due to overloading the molex rails or what ever you call it. must i plug out the 6+2 pin from my RM1050 everytime i'm done? thanks
