Is my PSU Ok ?

[Dicehunter]

Just opened up Corsair link and after watching a review my numbers aren't looking right, The numbers the red arrows are pointing to in the pic *The amps not the volts* for the 12, 5 and 3v, Should they not be 12, 5 and 3 ?

Idle -

Load -

As you can see even with a full system load the lower 5v never touches 5v and the 3.3v never moves from 1.40 at all when in an OC3D review video the 5va was at 5 and the 3va was at 3.

Could it be a fault ? RMA time ? or is this normal ?

Do you have a multimeter to hand?

I never trust software readings, even if it from the manufacturer.

Sadly not, It's not the voltage readings though it's the amp readings that are bothering me, An example is this taken from the OC3D review video where Tom had a load of roughly 200watts on the PSU, A picture of mine beneath OC3D's review and mine was also around the 200w mark although the amp readings on the 5 and 3.3 look off on mine -

I wouldn't worry about these readings. I wouldn't be surprised if there's a good amount of result massaging going on here to ensure the efficiency remains a good number and reassures the user they made the right choice in purchase.

Why would the voltage need to match the current?

At load the current on the 5v sensor rises from 2.8A (14W) to 3.6W (18W), the current on the 12v rises from 8A (96W) to 26.5A (318W).

Seems sort of reasonable to me as almost all the extra energy is going to the CPU (12v) or the GPU (12v).

130W from the wall at idle seems a tad on the high side though. Are you running loads of drives or something?

Well I am running a 980 Ti which at idle consumes around 100w

Based on the OC3D image it just look like that system burns more 5v and 3.3v. It's not night and day stuff really. Even though Tom's is double yours it is still only 25W vs 13W or thereabouts. It's nothing, really. Add a few drives, maybe some more RAM, a different motherboard that favours 5v over buck converted 12v then you could find your 5v/3.3v is higher.
