it has it's best efficiency at approximately those loads, however running below 60% usage is not going to harm anything at all.

Usually, a PSU's efficiency is maximized when the power consumption is at 40-60%. So, if you only game for a few hours each day but the computer is mostly idling the rest of the time (like how my computer is idling while I'm typing or reading posts), then it's usually best to have your gaming power consumption be at around 80% or so of the PSU's capacity in order to maximize the PSU's average efficiency.

 

In other words, if it were possible to be gaming 24/7, then you'd want that power consumption to be at 40-60% of the PSU's capacity instead of like 80 or 85 or so.

And if you're like me you don't really give a crap about the efficiency rating knowing your PSU quality is good enough to handle anything you throw at it anyway. smile.gif

Yeah, I admit that I don't care about my PSU's efficiency because I don't pay for the electricity anyway. Well, I should say that I still care because my parents pay for it, but they can afford it whereas I would probably have to be a little more careful.

Where would one go to find PSU load, anyways?
Not that I care much outside of "will it handle two cards?" but I'm sort of curious now.

Unfortunately, it's not as easy as that. Some might tell you to look at a PSU calculator, but those are just really bad estimators. You can look at GPU reviews, but there are some things to know before walking away from the review going, "Ok, now I know". To teach these things would be a waste of time because it's not important enough. :)

Before I actually get this set up, though.
Would my external connections make any differences, power-wise? Such as my dual monitors (144Hz) or multiple keyboards, microphones, headsets, etc. A fairly large amount of gear.

No difference at all. 144HZ 1080P monitors should run fine off of dvi ports but if you're above that res you may have to use display port. Power supply wise it matters not.
