you know that little bad you see in the quarter of almost every power supply box
that says 80 plus and then has some kind of a precious metal attached to it we're
going to tell you what you need to know about 80 plus as fast as possible the
original 80 plus was really simple 80 plus logo goes here the power supply at
20% of its maximum load 50% of its maximum load and 100% of its maximum
load had to be at least 80% efficient
converting power from AC wall power to the DC power that your computer uses
after a while it got to the point where it was becoming easier and cheaper to
build power supplies that were 80 plus efficient which is which is great I mean
power was being saved money was being saved trees were being saved it all good
things but consumers were looking for ways to continue to differentiate even
more efficient power supplies so over 2008 and 2009 80 plus bronze silver gold
and platinum were all introduced now some of these particularly 80 plus
Platinum is almost more like a 90 plus certification because it requires 90%
92% and 89% efficiency at 20% 50% and
100% loads but The Branding of 80 plus
remains power supplies that are extremely efficient but for example have
large voltage drops under load or exhibit a lot of Ripple can cause
long-term damage to your components even though they might be quite efficient
with that said most 80 plus gold and platinum power supplies these days do
tend to also be very very well built inside it just should be noted that you
got to watch out for those other things as well and it's important to still read
reviews for power supplies for those of you who were paying really close
attention before there's no 80 plus requirement for efficiency under 20%
load so that's why it's important to buy a power supply that is appropriate for
your system if you have a mid-range gaming rig that only draws 80 to 100
Watts from the wall at idle buying a 1200 wat power supply for it is
inappropriate because that's less than 10% of the overall power supplies
capacity that means this 80 plus Platinum power supply could be 90%
efficient at 20% load but it could drop all the way down to 70% efficient at a
5% load you don't know I'm not saying this one does in fact the ax1200i is one
of the best built power supplies on the market but as a general rule you want to
get something that is going to be somewhere near that sweet spot so you
want at least 20% load at idle and then under load you want it to be around 50
to 75% to take advantage of the most
efficient part of the efficiency curve which is not on this particular power
supplies box but I think you guys get the point thanks for watching this
