Why you can trust Tom's Hardware
Performance Rating
The flagship MSI PSU achieves top performance, meeting the Seasonic 1000 Prime Platinum and the EVGA 1000 P6 eye-to-eye.
Noise Rating
The graph below depicts the cooling fan's average noise over the PSU's operating range, with an ambient temperature between 30 to 32 degrees Celsius (86 to 89.6 degrees Fahrenheit).
The average noise output is increased, because the fan has to spin at high speeds at higher loads.
Efficiency Rating
The following graph shows the PSU's average efficiency throughout its operating range with an ambient temperature close to 30 degrees Celsius.
The average efficiency is high enough.
Power Factor Rating
The following graphs show the PSU's average power factor reading throughout its operating range with an ambient temperature close to 30 degrees Celsius and 115V/230V voltage input.
The APFC converter could be tuned for higher PF readings with 230V input.

tummybunny Thanks for a fantastic and very detailed review. Something that isn't mentioned though is one of the really interesting new features of ATX 3.0.Reply

"The 12VHPWR connector has 12 electrical pins and 4 side-band pins, for a total of 16 pins. The side-band pins enable low-fi communication between the power-supply and the graphics card, and two of these pins, labeled "SENSE0" and "SENSE1," let the graphics card know what kind of connector is plugged in, so it can accordingly adjust its power-management."
What difference does this make to GPU performance? Perhaps you could argue it's something better discussed in a GPU review but I would like to hear about it one way or another. -
Hresna Great PSU coverage… although the standard formula I think misses some aspects of a complete review…Reply
For instance this model offers an MSI feature they all “gaming intelligence” via the USB connector… no mention of this in the article or how it works, what it does.
I’ve been a longtime fan of Corsairs ‘i’ series which also use USB as the enabler, for the simple fact that it gives power output readings in hwinfo64 which is a fanstastic tool for dialing in power budgets, overclocks/undervolts, or just… those of us who like numbers and data. I can do without the iCUe software, which thankfully isn’t needed for this.
Does MSI’s GI do that also?
It’s extremely difficult to find PSU models with these sorts of features. At least the ‘i’ thing seems to be catching on and might serve as a semi-reliable indicator between manufacturers. -

What's this on the first page then?
"there is compatibility with the MSI Gaming Intelligence application, through which you can adjust several settings, like the fan's speed and toggle on/off the single +12V mode while monitoring the PSU's vital functions and power delivery. " Also google exists. -

Considering Aris is one of the top experts/reviewers in PSUs and he did a teardown. I'd believe him over the advertised specs any day.CheckYourFacts said:The Author asserts: "The four main FETs are installed into a full-bridge topology.

This is not about the authors reputation, which i know nothing about. It is about journalistic work ethics, his claim is in clear contradiction to the vendor claims. -

He opened it up and wrote what he found. If anything that would put the companies ethics in question not the reviewers.CheckYourFacts said:This is not about the authors reputation, which i know nothing about.

You might want to do a bit of digging and see what Kingston did within the last decade. If you can't find it, I'll help you;CheckYourFacts said:This is not about the authors reputation, which i know nothing about. It is about journalistic work ethics, his claim is in clear contradiction to the vendor claims.
Kingston sent out SSD's to practically every reviewer known to the (tech)community and once sales drove up to remove practically all units off the shelves, people all stated how the speeds weren't the same as seen by reviewers in spite of the advertised material stating otherwise. A further digging by TekSyndicate/Level1 found out about how cherry picked samples were handed out to help garner a better image.
That being said, please stop with the needless jabbing, the question falls onto the brand that sent the review sample out, not the person who opened up the unit to report what he'd seen. You're also talking about Aris, here. You're sneezing towards the wind.
If you believe everything that the brand's marketing material states, then AIO coolers MSI released were the best coolers in the world, not the market, the world. -

Okay so I missed that brief description.halfcharlie said:What's this on the first page then?
"there is compatibility with the MSI Gaming Intelligence application, through which you can adjust several settings, like the fan's speed and toggle on/off the single +12V mode while monitoring the PSU's vital functions and power delivery. " Also google exists.
And yes google exists, but my point was, in a review for something, if you’re going to mention a unique feature - something that sets it apart from its competition - might be worthwhile including a fulsome description and reviewing its functionality.
So I retract that it wasn’t described at all.
