I will build a low end-system using a Celeron G9300, the pc will be used to watch movies in Netflix.
This PC will be a gift to someone.
I need this power supply to:

- the most reliable/durable possible over years of use
- lower the electricty bill the most possible (regardless if it's MUCH more expensive)

Will an 80 plus gold PSU help me achieve this?
I was thinking about EVGA GQ 650 (cheapest one), Or the supernova version for almost double the price in my country?

I know my system at load will ouput like 250 watts only, but there arent low wat PSU 80+ gold in my country.
Thank you!
Sorry for my bad english
 
Solution
your better foff going with a good seasonic unit that in your price range at 80 percent unit. as long as it a good tier product it going to be using jap caps not cheaper china ones rhat wont last.

Argentina. Thank you for the help! I am doing some research but I'm not good at it.
If I throw 200ish watts at a 650-850 80 plus gold psu; will that make its better efficency not to count? I don't know if I explained myself well
 


Let me make sure I've got this straight...

1) Your system is going to consume about 200W according to your math. I'll go ahead and trust that.

2) You're looking for the most efficient power supply you can find in your country so the electric bill stays low.

Is that right?
 
Better efficiency help you save power, rather than providing more overall power. For example, take your own case. Let's say your components need 200 W at one point of time. Now, if you have a Gold PSU, it may draw around 215 W power from the wall to provide 200 W to the components, while a Bronze PSU may draw around 230 W (these aren't calculated numbers - just using them for explanation), So, a more efficient PSU draws less power than a less efficient one, hence reducing power consumption and lowering power costs of running the computer - though whether you'll benefit from this depends on electricity costs in your area, and how long your PC runs. So if electricity is expensive in your area, getting a more efficient PSU may save you some money, but if electricity costs aren't too much, even a Bronze PSU is good.

Do note that higher efficiency PSUs may also have better build quality and longer warranties, so you might want to take that in consideration as well.

Do they only go with high quality components in the Gold tier PSUs? Wouldn't other tiers be suitable as well, the differences in efficiency are minimal?

At the low power draw, PSUs won't reach their full efficiency so you'll lose a bit. But it's quite a minimal loss as I recall, we're talking a loss of maybe 2% or so in efficiency.
 


Indeed that's correct - Gold efficiency is really overkill for a build that consumes so little power - Bronze is more suited for it.
However, OP seems to want to reduce the electricity bill as much as possible, so I guess Gold rating it is. Gold PSUs should last pretty long - just check the length of the warranty, and you can take a guess on how much the company trusts the PSU to last. If it's anything above 7 years, it's pretty top-notch.
