A power supply is normally a black box: you find out what yours has been doing at the moment it stops doing it. This one reports for duty instead — live draw, efficiency, temperature and per-rail figures, all of it into iCUE where you can watch it live or log it and look afterwards. That turns a machine that rebooted itself mid-game from a mystery into something with evidence attached to it. 1200W of Platinum-rated output on ATX 3.1 underneath the instrumentation.

What It Pairs With
A card at the top of the range with a Ryzen 9 or Core Ultra 9 is the load worth instrumenting, because that is where the numbers get interesting. It earns its place fastest if you tune anything: being able to see what a setting costs in watts turns overclocking from guesswork into something you can measure. If the rest of the build is Corsair, everything reports into one dashboard rather than three separate applications each wanting to start with Windows.
Who This Isn’t For
If you will install the software once, look at the readings twice out of curiosity and never open it again, the telemetry is the main thing you are paying for here and it will sit unused for the life of the machine. It also means one more application running in the background, which some people avoid on principle and with good reason. Neither is a criticism of the unit — it is simply worth knowing which half of that you are before you buy.
Common Questions
What can I actually see?
How much the machine is drawing at any moment, how efficiently the unit is converting it, its internal temperature, and the load on each rail separately. The per-rail view is the one that turns a vague fault into a specific one.
Do I have to run the software?
No. Without it the unit is a straightforward Platinum-rated 1200W supply and behaves perfectly well — you simply do not see the figures. Nothing about its protection or fan control depends on the application being installed.
Is 1200W more than my build needs?
Quite possibly, and we will say so. Send your graphics card and processor and we will work out the actual figure — buy this one for what it tells you, not for a wattage number your parts will never approach.
Send your graphics card, processor and case model with the enquiry and we will confirm the wattage bracket and the housing fit. This one is ordered in rather than held in stock, so ask us for the current lead time with the quote.
