I don't need SLI or Crossfire as I'm only rocking 1 videocard. However, I am using 12gb 3x4gb sticks and the 1090t 6core amd3 cpu. Will this power supply suffice? It's 30$ cheaper than the one I'm grabbing currently which is:
I am not a buyer for the Raidmax, for two reasons. I can't find a qualified review of that unit, and Raidmax does not have sufficient psu reputation to take the chance. It may turn out fine, or it may be the cause of flaky problems a few months down the line.
I'd rather see you with this 520W Seasonic for $60:
if you plan on upgrading in the near future id stick to a bigger psu. dont cut it close so u cant really add and any new upgrades. also go for a modular psu if u can (itll save the hassle of all the extra wires/plugs u dont need.
If you want to protect against going SLI, you will want at least a 650W for 2x460s. You don't need more power than that, but you do need a quality psu regardless (Seasonic, Corsair, Antec Earthwatts or other unit specifically reviewed by a qualified reviewer).
I can't see Obsidian's recommendation lol, but the other rec's are good quality psus.
You don't need more than the Seasonic 520W you posted. It's superior to the OCZ if for no other reason than it will run slightly cheaper and cooler (Bronze rating). Further, I can't find a qualified review of that specific OCZ unit, and without that OCZ is not a psu brand I would recommend. That doesn't mean it isn't fine, I just won't recommend it.
As for OCZ's "SLI rating", both psus will do fine IF the total load for whatever SLI you would use is within their range. They have identical PCIe cables, too.
