ATX 3.0, which was finalized back in February, is Intel's latest power supply standard. The new standard notably supports the brand-new 16-pin 12VHPWR power connector, which allows for up to 600W of power consumption from a single cable. ATX 3.0 also introduces a number of new power specifications, with improved efficiency and reliability ratings and a much higher tolerance for power spikes. 

MSI's new MEG Ai1300P PCIE5 features higher quality components compared to previous designs. MSI says the unit can handle up to double its power, or 2,600W, and is designed to counteract the large power spikes expected on next-gen GPU hardware.

It may be able to handle 2600w power spikes, but my 120v 20a circuit most certainly can't. I don't see how that matters to the average consumer. 2000w max, fine that works for me, but not 2600w. This MUST be being marketed at EU/Asia customers.

Yeah this is the first thing I thought of as well. There are other problems if I spike that much power.

They're just saying it has a lot of headroom.  It's a 1300w power supply that can handle double it's rating for short periods.

So it can do it independent from the AC input from the wall? I get that they are addressing transient spikes. I just didn't think it was possible to sustain even 1ms without matching input.

It's just marketing, that it can handle more than it's rating.  Also the most common breakers are thermal-magnetic breakers, they don't trip instantly.  I've seen in rush currents exceed a breakers rating many times.

Power supply have Capacitor. They have enough power to stay on even after power is shutdown.  Hold Up time is tested in some review.

 

That probably what they mean by 2600w.

lol,that makes everyone feel much more secure using 1 of these. Plug your new build in with your monitor on 1 line and the wires in the wall catch fire because the breaker doesn't trip in time....

Not really. Romex, used in houses is rated at 90 degree's so if we look at the 90 degree column we see that 14AWG can handle 25 Amps and 12AWG can handle 30 Amps, but by code the sizes with the ** can only be breakered at the 60 degree rating.

Yea but like a said power supply have capacitor. The 2600w peak come from them not from the grid. I think? No?

 

Ive seen 2000w on my kill a watt and a melted 120volt wall plug. No fire

2000W is 16.6 Amps, unless you're plugged into a 20 Amp outlet on a 20 Amp circuit, you might want to unplug something.  The breaker and the outlet can handle spikes above it's rating, but it shouldn't be continuous.

At this rate i guess ill just future proof my house and install ACB's. At least they sound nice when they arc.
