what would happen if you used 2 powersupplies?

[Zatrix]

Like say for example you connect your Motherboard, CPU, and graphics card with one psu and then your hardrive, cd rom, floppy, and fans with another psu??


what would happen. im curious.

[jcw122]

if i were to try something like that...id do it like this....1. mobo g-card HD 2. CPU floppy cd-rom fans ...that would equal it out a lil better....but even if u tried doing this u would run into the MAJOR problem of having the 2 PSU's turn on at THE EXACT same times so u dont screw up stuff....but with ur set up u gave above it might not be such a problem....but u would still need 2 on switches....and i donno how the hell ur gonna get 2 on switches to hook up to ur mobo.....but i get ur point...u wanta do stuff like hook up less stuff to a PSU so they can be more stabley powered stuff? good idea...but i doubt it will work EDIT: yeah thats alotta stuff lol

Nothing, except you'd have a lot of extra connectors and power for other devices

I run 2 PSUs in my system.

I do not recommend mixing the power of the PSUs since no two PSU have the exact same ground potential. You could end up with ground loops and other problems.

I run mine completely seperate. One for the System. The other is for cooling.

How do you do it?

OK here you go.

Buy 2 of THESE (http://www.quietpcusa.com/acb/showdetl.cfm?&DID=8&Product_ID=12&CATID=4)

Follow THIS (http://www.burningissues.net/how_to/power/adaptor.htm)

Which when you are done will look like This

Then mount your PSUs similar to This.

i run dual fortron 400W PSU (cost me $120 and i got more power then most all PSU's over that prive range) - connects in a CM stacker - which includes the connection to join them both - as said - you will end up with alot of power and lots of cables :) but if i go SLI i got no worries :D

i heard this is a very good psu?

it looks great and from the reviews it shows that its VERY GOOD.

[Mr.Guvernment]

thankx Zatrix - cant wait till the year i get it done ..lol :D -i am not sure where u can grab those specific PSU's from - but i will say Forton makes good ones - these 400w ones i got - i cant recall how i got it split i think

1 PSU - mobo / 2 x 120mm fans
1 PSU 2 HD's (1 raptor / 160g WD / cdrom )

i am about to mess with my abit AI7 and possibly throw in 2 more HD one 120g and one 80g - see how well the 12v rails hold then -


Right now my rails sit @ - accoriding to ABit EQ (not sure which PSU it is measuring)

3.3v @ 3.4v
5v @ 5.1 to 5.3
12v @ 12.2 upto 12.6

I gues if you can use 2 PSU's and have a case for it - i say go for it - you can buy 2 $50 PSU and get more power then 1 x $100 PSU - and also if one PSU's blows - u got another for back up time being :D
