Dual PSU Configuration Question

Hello everyone!

I have a question about dual-PSU configuration. Currently I have Chieftec 620W PSU and I am planing to buy another 650W to make dual PSU configuraton.
You can see my PC's cureent configuration in my signature. But I'm plannig to do some upgrades sooner or later, starting with graphics card and then other stuff.

What you say about this configuration?

PSU 1:
Motherboard, Adaptec PCI SCSI controller card, Adaptec PCIe SAS controller card, Radeon 5870

PSU 2:
6 SATA HDD's, 2 SCSI 7200RPM HDD's, SSD drive, 3 SAS 10k RPM drives, ~8 case fans, Fan controller, DVD-RW drive, Radeon 5870
 
I say you should get rid of the crappy Chieftec PSU and just buy a good quality 750W or 850W PSU to run everything at once. You won't have to spend a whole lot more, and in the end, you'll benefit a lot more from having a better setup than you would from saving a few bucks.
 
get 1 high rated PSU instead, it will save you more $$ in the end due to less energy being used in the long run.
 
Yup, like these two said, ditch the POS PSU and grab a nice 750 or 850w Corsair PSU and you'll be set.
Dual PSU's tend to be inefficient and potentially hazardous to your setup as a whole, it's a good idea to just avoid that setup altogether.

The only disadvantage to a dual PSU setup is the inconvenience. It is not more dangerous or less reliable than using a single PSU.

Actually I want to agree with you about the fact, that it is not more dangerous or less reliable. Why do you think that it's inconvenient?

Probably because you'd have to find a case that fits two PSUs fine, have to use a special cable in order to use both PSUs at the same time, and probably all sorts of cable management issues.

But yeah I concur with Zero82z and recommend that you ditch that crappy PSU and go with a good quality Corsair 750W or 850W PSU.

Space is not a problem at all. I can almost fit another computer in my case. :D And getting that special dual-PSU cable is no problem too. And also I have no dubt that Corsair makes good PSU's, but I think that 850W won't be enough for my future plans but 1000W and more powerful are too expensive for me right now. But still thanks for your reply. :)
 
What kind of upgrades are you planning? A good 850 watt will handle any kind of dual GPU configuration besides an SR-2 build.

Currently I have 8 SATA HDD's and ther will be at least 3 15,000 or 10,000 RPM SAS HDD's more, 2x 5870 Radeons, Adaptec PCIe SAS controller card, DVD-RW, Blu-ray writer, ~8 fans. And sometimes I have to connect Adaptec SCSI card to add 2x SCSI HDD's from one server.

This is only the list of componets which I'm planning in near future. But there could be something more so I want to feel safe that my PSU will have enough juice and be future proof.

Danny answered correctly.

If a good 850W PSU isn't enough for your future plans, two crappy ~600W PSUs won't be either.

850W is plenty for that, and if you really want to be "future proof", wait until you can actually afford to upgrade to something decent and then just buy a good PSU.
