AX1500i efficiency

You're using less than a 1/10th of the wattage it can dole out. Platinum has no standard efficiency rating for 10% output so you're likely to fall below the 92% (I believe it's 92% for Platinum at 20% output) since they can fall below their rating anywhere that isn't measured.

You're only using 122W of power.

It's not 94% efficiency from 0W ~ 1500W.

PSUs are usually most efficient (very close to advertised) in the 20% ~ 85% load range.

Don't buy stupidly large wattage PSUs...

LOL I though I need it for two titan x pascal and HTC vive.

when I play shadow of the tomb raider sli at max settings it will only consume 600w, 1500watt psu is way overkill.

No one shows us how much pc games consumes watts they only care about fps …. so I bought the …. best thing available.

It's a bit worse with 110v AC mains voltage.  From : https://www.techpowerup.com/reviews/Corsair/AX1500i/6.html

 

86% is a good efficiency for 120w (less than 10% of its maximum output)

 

so my psu is broken or faulty.

Yeah, you needed a 750W supply, not a 1500W supply...

 

Anandtech does a very good job at showing system power draw in their reviews, so you mustn't looked very hard...

No, you are just using fuck all power (look at the graph), and PSUs just CANNOT be really efficient at really low wattage. A lower wattage PSU would be wayyy more efficient.

shouldn't it be more than 86% or is it normal?

Most PSUs aren't that efficient < 7% load.  Hell... most aren't even 70% efficient at 7% load.

 

Use the logging feature and see what your efficiency is during a game.
