How much of a difference does going from 80+ gold to 80+ titanium actually make for power usage?

[rippy4500]

I may be getting a high end 40 series card and theyre supposed to use tons of power (4080 is 420w) and if i do end up having to replace my evga 750 g5 to run it should i spend the extra on an 80+ titanum psu?

 

if i do end up replacing it im looking at 2 different units

evga 1000 gt 80+ gold (on a teir in psu teir list) around 140 usd

evga 1000 t2 80+ titanium (also on a teir) around 220 usd

 

is that extra cost worth it? how many watts will i actually save?

 

Theres 3 reasons im considering a more efficient psu

1: ill save money on my energy bill, energy is a little expensive in my area so i may actually save money over time

2: i only have a 15 amp breaker in my room and i dont want to trip it if i have other things running.

3: better components, ik 80+ doesnt equal quality but im pretty sure 80+ titanium requires higher end components to achieve so maybe.

 

I dont plan on replacing my psu if i dont need to, so this post is just in case i do so i want some advice.

You dont need that, get a good gold unit.

Define "a little expensive." Assuming a cost of 20c/kWh (slightly above average for the US), a full system load of 750W (high, even for the rumored 4080), and 8 hours a day of gaming, it would take 5 years to even break even. If you game a more average amount, it would take even more time to break even.

It's a difference of 50W at most, the odds of that saving you from a breaker tripping are very low.

How long is it going to take to pay off that $80 price difference, though? The target for Titanium is only about 3-5% more efficient than Gold, so it will probably take years just to break even.

Quick look at 80Plus ratings...

GT while outputting 203W, takes 222W from the wall. T2 when outputting 204W, takes 216W from the wall.
GT while outputting 506W, takes 546W from the wall. T2 when outputting 508W, takes 534W from the wall.

GT while outputting 1004W, takes 1127W from the wall. T2 when outputting 1012W, takes 1084W from the wall.

 

Difference of about 6W at 20% load, 12W at 50% load and difference of 43W at 100% load.

Let's say 1kWh is 10¢, even running at 100% all day, power usage bill difference would be that 10¢.

And mostly idling, difference is maybe 1¢/day.

My energy cost has been going up a little in recent years, used to be around 18-20, now its around 21-22. Also ill probably be using it for 10+ years assuming i dont need to upgrade it, so it may break even sometime during that period, especially if the price for the psu comes down, idk tho. Ill be selling my 750 g5 and my old gpu if i upgrade it.

I could look for platinum or find a cheaper titanium unit, but idk. Ill be using it until it breaks(or i need to upgrade) which could be 10+ years from now, so it will likely break even sometime during that period, even if it takes a long long time, especially if energy costs come up.

 

 

 

also the 850 t2 is 30-40 dollars less so i could consider getting that.

It'll still not be able to break even. Again, the numbers I did were entirely unrealistic (gaming for 8 hours a day, every day), if you up that to say 25c/kWh and game for 4 hours a day (still not realistic, but more realistic), it's a price difference of ~$15 a year. It'll take 6 years to break even if it jumped to 25c/kWh tomorrow, taking pricing increasing over the years you would be lucky to break even in 10 years.

That defeats half the reasoning for getting an titanium rated unit, since it's a bit past the efficiency curve. Plus it's very debatable whether the 4080 would run on an 850w

i think i saw the 1000 t2 go down to 210 or 205 one time but idk, i can check price history to see if it may go down at some point. If i get it when its low like that it might make more sense.

edit: it went down to 210 at a couple points and went down to 199 at one point after checking price history on pcpartpicker, i can wait for one of those price drops.

 

the 3090 ti which is 450w recommends a minimum of 850w.

4080 should be 420w, which is less. and the 850 t2 is high end so it is probably capable of it. And i think the efficiency curve doesnt change much unless the usage is really low or if its being pushed past its rated capacity.

It really sounds like you are trying hard to justify getting the titanium psu. If you like it and have the extra cash, just get it. Life is too short to fret about $40 price difference.

If you size it to run in the optimal range they have some gold PSUs with 91-92% efficiency.  They just tend to fall off a bit more than platinum at the lower and higher wattages.

I mostly want it because the t2 is high end so it probably has better quality power output than the gt i was looking at. And i like to overclock cpu and ram alot so it would probably help me there a little bit.

 

And also because i want something nice that will last probably 10+ years.

I was looking at the GT but since it is no longer on the TierA list I got a G6 which is 1000w, good price and still listed as TierA.  The only downside is I had to get online because they didn't have at MC.
