Did I do the math on my psu right?

[SammyGoad]

So I got a thermaltake smart series 650watt psu and my system with a 2500 and crazy windforce gpu draw plus three fans, hdd, and others draw 300+ watts under load. The 80 plus Bronze rating of my PSU states that it will be most efficient at 50% load. Does this mean my system will be running the most efficiently while playing games?

the efficiency doesnt matter enough for you to care about the specific percentage under load.

 

if you're that worried about efficiency, get a modern processor

That PSU will work fine for that rig. Even though I think you would be fine with Almost any power supply with 2 6 pin PCIe connectors, its always good to aim a little high on the wattage.

(I say that knowing what it can be like to just be on the edge of your power supply's limit. You don't want to do that.)

It means your PSU will be most efficient while playing games.

In addition to the above, there may be a point, such as 50% load, where the PSU is "most" efficient, but that usually means something like 81.5% efficient as opposed to 80% (your results may vary). That 1.5% difference would only add up to about 50 cents extra electricity cost over a year. So don't worry about it.
