At 850W it's the highest wattage PSU Seasonic has ever launched, where as everyone else has chased the four digit threshold that very few people care for, instead the new frontier in PSU technology is efficiency.

I also assumed that for a 50% efficiency (just using a low round number for easier comparison), if your system needed 300W, you would have to have at least a 600W PSU

But from what i read a while ago (don't remember the site exactly), i understood something like this: If you have a 500W with 50% efficiency, it DOES provide 500W, but it draws 1000W from the wall socket, therefore increasing your electric bill. Again, i`m exagerating with the percent, for easier comparison.
I am also puzzled about the fact that my PSU is 280W, and i used an HD4870 512MB and 2x HD4850 CrossFire on my EP45-DS3 with my trusty E2140, running at 3.2GHz (100% OC) and I didn't have any problems. No artefacts, no restarts. I also tested my system with a Gigabyte Superb 720W and i got the same results. By my calculations, my PC should've ran out of juice with my regular PSU :)
Can you explain pls?

I bet you did the load tests, while you can't publish them, was the PSU actually 80+ silver ?

If you need all the cables, why buy a modular PSU?
