Ok I ordered the corsair AX760W
Since you already ordered this, no harm done. It currently is on sell for a great price at
Newegg so I would be tempted too (if I needed a new PSU now). And being Platinum, it will still be very efficient even if barely tasked by a small load. And the advantage there is fan noise should be minimal, if not zero, most of the time.
I also feel you pay too much of a premium for Gold, and esp Platinum ratings, for what are mostly just pennies saved at the end of the year on your electric bill.
There is a lot of truth to this but I still recommend Gold when possible because they still "
generally speaking" (with exceptions of course) offer better regulation and ripple suppression than lessor rated (and non-certified) PSUs. At least get Bronze if the budget it tight. There really are not that many Silvers to recommend. But I agree the extra savings Platinum and now Titanium certified PSUs give you in efficiency would take a long time to recoup on your energy bill.
That said, if your conscious says to be a tree-hugger whenever you can, no harm in getting a Platinum.
If our motherboards, graphics cards, and other connected devices needed that sort of quality power, that would be different. But board makers have put a lot of effort to put good regulation on the boards themselves.
To some, "perfect" means just enough without being overkill, to others, it means 100w headroom for long term use, to others, 50% more than required for possible SLI/Crossfire later on.
I am, more or less, in the extra 100W headroom category because I don't know what I
might need 3 years from now. I might want to upgrade my computer with more power hungry components and spending a little extra $$$ today for 100 more watts will save me a lot of $$$ in 3 years by not needing a new PSU for my upgrades.
I think for most home users it is mistake to buy a PSU that is "just enough" today simply because it leaves no headroom for future additions or upgrades. Not all upgrades are planned. A graphics card can fail and need to be replaced, for example. Many may wish to upgrade it in the process and maybe add a couple more sticks of RAM too. That extra 100W "should" easily take care of that.
This is another reason to build your own so you can plan for future unknowns. Sadly, many factory built PCs have a power supply that is just barely adequate to support the existing HW with no room for upgrades.
