Anything less than Platinum or Titanium ratings shouldn't be allowed. Inefficient power supplies are uneconomical and the manufactures know this. Building, selling and promoting inefficient power supplies is unethical.

How unethical are we talking about here? The difference in efficiency between Gold and Titanium is only about 5%. A 750 watt PSU, even being inefficient, pulls less wattage than a toaster. But, also, the efficiency rating doesn't specifically dictate the quality of the PSU at face value.

Agreed, but one note: Titanium lowers the efficiency starting point from 20% to 10% load which is the important difference.

Cybenetics has much more in depth testing protocols than 80 Plus and is far more useful for picking a PSU than anything else aside from an in depth review like this one.

Yep, on Corsair's website they have it listed as Cybenetics gold certified with a noise level of A+ (15-20dba). Having that extra noise rating is kinda neat and Cybenetics certifications seem to be more strict/detailed than 80+ certifications. Honestly looking forward to more by Cybenetics.

They just launched their performance database: https://www.cybenetics.com/index.php?option=psu-performance-database

Thats honestly a pretty good start. I don't know if I just haven't been paying attention but I find it interesting that they have test reports from all the way back to 2017/2018. Speaking of reports, they seem to be pretty nicely layed out with decent charts/graphs.

I think it speaks to how long they've been working on their specifications and refining the process.

We could be reducing power consumption on a massive scale here with a simple and cost effective change

climate change is a real and pressing danger, people are suffering and dying

if you thought about it

You cannot call this review in depth. The review is missing the ATX 3.1 compliance test, no hold up time measurements, no comparisons to competitor models.

TH should go back to their testing methodology and update them for PSUs and follow them for their PSU testing. The currents testing methodology is a far cry from what TH did a few years back.

I'd argue there are likely more effective ways to reduce global power consumption than worrying about the small percentage difference of PSUs.

I say that because I thought about it, logically.

what about coilwhine on this 2024 units ? i had 3 corsair shift and all of them had this anoying constant high frequency whine.
