Anyone else feel wrong about buying >= 1000W PSU that is Gold rated?

I know this sounds weird but anyone else feel like this? As in something hard wired in your brain says to you "If you have 1000w it should be at minimum Titanium".

 

I first thought of this after reading the conclusion of the 2021 RM1000x by Tom's Hardware: "There is not much competition in the 1000W Gold category since most PSUs with similar capacity are Platinum or Titanium"

80+ is just a measure of efficiency. There is some benefit of having a more efficient PSU in high wattages because higher efficiency will result in less energy being wasted as heat, but as long as the PSU can properly dissipate that heat (proper heatsinks, fans, components rated for high temperatures) then it's not an issue.

 

There's probably not that much difference between an 80+ Gold and 80+ Platinum PSU anyway.

For example the new RM1000x you mentioned compared to the HX1000 Platinum there's barely any difference as far as the 80+ ratings which measure at 10%, 20%, 50%, and 100%. There's only 1% difference between them at 50% and 100% load. At 1000W load that's 10W difference, considering you're already pulling 1100W+ with 120-130W being wasted due to efficiency losses an extra 10W loss isn't particularly an issue.

 

80+ Titanium PSUs will have more of an improvement over the 80+ Gold units, and they're also required to hit efficiency targets at 10% load. They will generally be quite a bit more expensive though and unless you're running your system at full load constantly the higher upfront cost likely won't be paid off by the energy savings over the life of the PSU.

 

I guess the main reason would be "If I'm already spending $150+ on a power supply, why not spend an extra $20 to get the more efficient premium one?".

There might be other reasons to pick the 80+ Platinum or 80+ Titanium units like maybe the more expensive one also comes with extra cables, longer warranty, a better fan, or some other reason.

 

There's no right or wrong answer to whether or not you should buy an 80+ Gold or Platinum/Titanium PSU.

To you Titanium means high quality, right?
Let's think about that...
If you buy a 1000 W power supply for a PC, you probably don't care about the energy costs too much.

And a difference of around 5% in efficiency is not a lot.

High efficiency comes with high distortion, which requires filters, so at some point, it makes no sence to make it more efficient.
To me, it's much more important, how quiet the power supply will be and how long it will last, because these are the things you will notice.

No.

 

92% at 50% (500w) ... 92% = 500w => 100% = 500 * 100 / 92 = 543w 

95% at 50% (500w) ... 95% = 500w => 100% = 500 * 100 / 95 = 526w 

 

8h a day of gaming, 31 days in month => (543-526) x 8 x  31 = 4216 = 4 kWh  at ~ 0.2$ per kWh = 1$ a month extra on your power bill.

No there's really not a use of a 80+ titanium rated power supply until you are going to run the machine for so long continuously.

80+ gold is enough for what gamers need

[Hybris5112]

The efficiency standards the more I learn about them seem to matter less and less. The only thing that I would expect is assuming that a given PSU is honest in meeting 80+ Titanium or Platinum requirements that PSU is more likely to built with better quality parts in order to meet said standard.

 

Unless you are living in someplace where the price of power is vastly above average focus on getting a good quality, long lasting 1000w psu and you are set for the foreseeable future.

80+ is entirely irrelevant to most gamers' needs.
