Any advantage using two power supplies? - Page 2

post #11 of 20
You could get away with one 30a 240v circuit + a serious PDU. I guess the costs to run one circuit is about the same as it is for two, though.

You figure 1 circuit can support 1 washing machine & 1 dryer so that's 2 1500w PSU's so 4 unless you really beef up the breaker + use a heavy duty Professional Power Strip to split the line the 4x 1500w may still overload it. Well.. when you run Tec's at least power hungry monsters those can be. LoL, once my dual system finally has all the ultimately intended hardware I've chosen I might even have to really consider installing the 2 lines::

Currently running dual PSU’s in my T10. Corsair AX1200 runs my MB, 2-GTX570’s, HD’s, and DVD drives. Corsair GX430 runs my 2 water pumps, fan controller, and 12 fans. Just wanted to keep all my water cooling on its own PSU.

What PSU topography does the GX430 use? Until you know, do NOT use the GX430 to power any real components. The mechanical devices are ok since they are more tolerance to ripple and poor regulation.

The reason is most PSUs have a cross-load characteristic that requires some load on the +5v/3.3v rails or the +12v will not run properly.
Once again...

This is useful to know, I've thought about adding a third psu in the tx10 build just for running all the high restriction cooling.

I've thought about doing this in my TH10, buying a small 500W or 600W PSU to run just my fans and WC equipment on. Makes bleading and testing a little easier. But, what I worry about is having my small PSU go out and my CPU not getting coooled when my pumps aren't running. Is there some way to daisy chain the PSU's so if one goes down they both do?

CPU will throttle before it damages itself.

If you are worried install a program to warn you if CPU temps exceed some threshold.

Depending on fans and pump, you might be able to get away with +12v power brick.

Yes they can be put in serial as opposed to standard parallel however to do so is difficult and voids most warranties I found the directions to do it several years ago on hardforum.com they still may be possible to find there. If you are so worried about it do as is stated in DuckieHo's post i would also add in a flow alarm though.
