How much more efficient will the gold label bring?

[amuffin]

Is there a chart or estimation of how much money will be saved between all of the 80 plus labelings? Such as plus, bronze, silver, gold, platinum, and titanium?

 

[esrever]

Very little improvement I would think.

gold is 87% while 80+ is 80.

the 7% would be like 10w on a computer. 8 hours a day over a year would probably be less than $10 at least in north america.

are you serious..... Then what is the point of gold labled psu's costing much more than an 80 plus bronze psu?

 

[esrever]

people like efficiency I guess, also the extra gold certified gives people something in terms of quality check I guess.

 

[delluser1]

The difference between80+ and 80+Gold is 10% at 50% load

Would equate to quite a bit more than 10 watts when a system like amuffin's is under load.

 

[esrever]

I guess since he is running sli 560 tis it would be more but generally a machine sits idle drawing less than 200w. which is generally below the 50% of a psu load.

There is another benefit from the gold rated psu's. Inefficiency is turned to heat. Heat is something that you don't want in your computer. Less heat also means the cooling system doesn't have to work as hard to cool your computer, so there is also a secondary efficiency, and less wear and tear on your components due to less heat generation.

Well I am thinking of switching over to a gold psu because it could lower the electricity bill...I guess that isn't really the case :lol:

Not by enough to be noticeable.
Best reason is the one tk laid out, cooler components last longer

Would this one be a good upgrade over my current antec one? http://www.newegg.com/Product/Product.aspx?Item=N82E16817151087 going to switch my antec one over to my hackintosh.

Only a 4% difference in average efficiency between the 2, not really worth it in my opinion, unless the other system really needs the Antec upgrade.

The other one was a rocketfish 700w psu which gave out like 3 days ago Is there a good psu that is cheap that can power an i5-2500k and a radeon 5450? It'd be nice if it was modular...

 

[esrever]

a earthwatt 380d should be able to power the hackintosh

 

[delluser1]

+1

Know of any good modular units though? Should I get this corsair unit? http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026 It is 17 dollars off of all discounts.

 

[esrever]

that should also work but to get a modular one is gonna cost you a bit more.

http://www.newegg.com/Product/Product.aspx?Item=N82E16817341016

that might be good.

Aren't ocz psu's bad? Actually I think i will go with the corsair one. Thanks for all of you guy's help!

saving depends on load
a 1000w 80+t will use ~1042w at full efficiency (if output is 1000w)
a 1000w 80++ will use 1250w at full efficiency (if output is 1000w)
thats equals to ~200w of savings per hour (equals ~10 tubelight of 20w)
runing these machiene for 10hours a day will make a difference of 2000w of power
if rate of electricity is X$ per unit (1kwh) then you will save 2X$ per day, equals 730X$ per year
if rate(X) is 25cents per unit then it will equals 182.5$ of savings per year
