About power supply

[PerfectCircle]

I have a question about using two  power supplies in one motherboard, to avoid any bad result is it always better to use same power supply? 2x Corsair power supply with exact same rating and watt? Or you can just match any power supplies and they will still work fine? Thanks

Which motherboard are you going to use?

But general rule, you don't need to have 2 identical power supplies, you can mix wattage and brand without any problem
You'll use a piece called add2psu to connect two PowerSupplies or you can improvise and use just a clip metal or a small cable to start the secondary PSU in the same time you power on your rig/pc.

Yes also do not forget NOT mix +12v. i mean connect same gpu and riser to same psu.

Any power supply will work, this isn't anything like SLI or Crossfire that needs same GPU in one motherboard, I've used Corsair with OCZ PSU before and it works, one is 750watts and the other is 600 watts
