80 PLUS Efficiency and What It Really Means

Recommended Posts

Posted · Original PosterOP

You seem to forget the fact that your CPU and GPU are not the only things with a tdp ratting it also has to account for your other components and the power draw of your fans.

Yes, and fans and hard drives use very little power. I'm just saying it's not really accurate. It also varies with different hardware.

 

In general I can say it's a good idea to get a PSU with more wattage than listed by PCPP but you shouldn't use it as the be-all and end-all of wattage calculation.

Praise the lord ! At this rate there will be no more threads asking for what PSU to choose !

The thing about Haswell Compatiblity and group regulation and whatnot that I said I'd include in mine

 

Your threads seem to be a lot more popular anyways <_<

I put this up in a hurry cuz I saw two people in one day say that you get better build quality in an 80+ Gold than in something lower so I got fed up and just made it. I might ask a mod if I can give you access to it to edit it though I'm not sure if that's possible.

 

For now just type up what you want me to add and I'll put it in there.

If you made a similar thread I have no doubt that it would be a high quality post which I would 100% reccomend.

I have a question. If i have EVGA G2 850W power supply with 80 plus Gold, how much watts do i get from 100% load? 

You are using around 850W? Or do you mean from the wall? The math is on the main page. A lot of people think that you're only getting the rated wattage from your PSU in a percentage of the 80+ rating - IE, a lot of people think an 80% efficient PSU of 500W means that you're only able to draw 400W from it. Incorrect. You are able to draw 500 but you're drawing more from the wall.

 

So. Math.

850 /.87 = Amount drawn from wall (977 watts)

Ooooooh, so i did my math wrong then. What i did earlier ago is 554 watts(total power consumption with two GTX 970)/.87(gold) = 663 watts LOL.

I remember I made a thread like this on pcpartpicker years ago and well I got hate messages of people who don't know what quality is... Just because it's a name brand doesn't mean it's good...

Eh you're probably not getting quite 554W with two 970s unless they are hyper overclocked. Still you should be good on a 650W PSU with two 970s.

Well, i think 850W power supply should last me a while or more  :) , because i'm planning to go with water cooling setup on next build so............

You'll still be good on a 750W PSU even if you watercool :)

I still don't know how much is going to consume on my next build, but i hope my 850W is sufficient for it.
