Dual PSU = More Stable Rails??????

Dual PSU??????

I apoligize for grammer and spelling. I have made a 'Y' cable to connect 2 power supples and I was just wondering if I will see more stable voltages coming out of my power supplies? As of right now I don't have a case that will house a second PSU but when I do, if I connect only the motherboard to the primary power supply, will my motherbaord get a stabler voltages? Will each of my 12V, 5V and 3.3V rails be more stable? Or will I just have more power?

I followed the guide here at Burning Issues;

In theory it should as long as both PSU's give good rail's... there won't be a ton of stress on either of the PSU's like there normally is so the rail's shoulden't crap out.

if you need a case


coolermaster stacker!!!! (i am getting dual 400w fortrons)

(no i do not work for coolermaster)

It "should help" but some PSU's just simply can not hold a stable rail.

So if the PSU's are crap, there just crap. But it should help things right? I'm custom building my own case. Basically going to a server style cude. 2 mid towers together. With the motherboard only on one side and everything else on the other. Construction almost complete then on to the painting.

ya, crap psu X 2 = 2X the crap. one good strong psu should be good..ie. 550W fortron, sparkle, antec, ect..if you need 2 then get 350w..name brands

That is definately correct here is the setup I'm currently building with dual antec PSUs. This is for a Full Tower Dragon Case. I made the Bracket out of 1/2" Lexan.

hmmmm, nifty!
hows that working out? i gotta junk 500, and an OEM dell 250... the 250 will actually do me on its own , and its supposed "quality" (i worry though) but its too noisy to mount on an outside wall (heat, heat, heat, i know) why 2 nice psu's? you gotta be Pelting or something, eh?

 

[CrashOveride]

Less load means less heat wich means more stable voltages, unless they are already stable (like a quality PSU). A crappy PSU still might not be great but less load should help.

Well my single Antec 430w Trupower was crapping out on me till I volt modded it. Saved me the space of not having to add a second PSU and only cost 5 bucks to boot.

Why 2 PSU's because I trying to see if I can put enough fans on this thing to levitate it off the ground. I'm still building the case I should have it done in the next week or so. when finished I will be moving in excess of 1000 CFM through the case. which should rival any watercooled system out there. The PSUs are a Antec 430 True Power and a Antec 450. I figure that should cover it.

1000cfm eh? someones not going to be able to sleep. with all that money into fans, im sure you could have built a wc system

Your probably right I could have. Why didn't I well I have had years of experience working in industrial automation. Using Pneumatics, Hydraulics, Air over oil systems compressed air cooling systems you name it. and sooner or later they always leak or condensate and something goes boom. that is the main reason why I did not go that route.

I have 9 fans and they total 410CFM. How many fans do you have and what are they? I'm going to be making 12V/5V switches for them or sticking them on rheostats so I can sleep at night.

OK here goes. I am still building my case but I already have all the fans and my design is complete.

EBM 150 MM 203 CFM
Delta 120mm 190 CFM (Ducted intake to CPU)
5 TT SF II 80mm 72.7 CFM X 5 (363.5) CFM
1 80 mm TT Smart Blue 72.5 CFM
1 92 mm TT Smart Blue 78.7 CFM
1 120 mm TT Smart Blue 93.7 CFM
1 80 X 15 Zalman thin fan 30 CFM

1031.4 CFM combined total.

Of couse this does not count the dual PSU fans and the PCI Slot fan and the fans on the removable drive bays. I will be controlling all of the fans through fan controllers or Rheostats. So it will have a sleep mode so to speak on it. This should keep it nice and frosty.

 

[ClarkKent]

That is a lot of CFM. I'd like to see you add up your dB(A)'s and see where they are at. How would you do that exactly cause you don't just add them? Too much math for me anyway. If any one knows how to o that it would crazy to see.

 

[anitract]

With that number of fans, might as well build a case-less system.

Back on subject, I recommend the Cooler Master Praetorian (in Silver or Black). I have the black version and absolutely love it. Very nice looking and very cool inside. 2 80mm intakes, 1 80mm rear exhaust and 1 80 mm blow hole.
