Load regulation is tight enough on all rails. Moreover, this is among the few times I have seen a PSU with a load regulation within 1% at 5VSB!

Ripple suppression is good on all rails.

I see all your expensive testing equipment push to the limits but please no 30 pages ahah.
This PSU is gorgeous, look amazing for the people with a pc case showing it on the side/bottom. Some luxury sport car with the chrome look.
Breaded cables very nice. It’s a personnal pref but downside they are 60-75cm ! I built a few mid-tower pc and i never needed more than 50cm for the ATX and GPU. Big hassle to hide all this extra ;(
510€~ on Amazon for this monster, if i was not beyond the return window for my own PSU i would be tempted.
I snatched a MSI MEG AI1300P for 279€ with the MSI Cashback/Review. Decent for platinum 1300w. I like the fact that the fan control is possible with msi center and usb mobo. Plus it’s start running auto by default only when it’s 65°C i believe.
I highly recommend setting the PSU to the minimum fan RPM of 700. You don’t need the MSI software to keep running after you set it.
I have this PSU and in my opinion, the fan starts way too late. I don’t like the amount of heat the PSU puts out, so I left mine running like specified above, and the PSU never heats up past 48C even during intense gaming (4090 and 14900K).
I will replace it with this Seasonic Prime TX-1300 unit in a bit, though. Only reason I got this MSI was because Seasonic had no ATX 3.0 units at the time. I always feel more comfortable with Seasonic in my rig – not to say the MSI is bad, far from it. It’s a very high quality unit. I’m just a Seasonic kinda gal.
Thank u for your input.
Aris, have you noticed any weird noise when the PSU fan starts or stops? Or erratic fan behavior in this unit?
My Seasonic Prime PX-750 had the fan start up and stop constantly while I was gaming. The fan itself was quiet but I could hear a weird rattling noise for one second as the fan started or stopped. This also sometimes happened at idle.
Are u sure it was the fan?
100% sure. It would happen when I switched Hybrid mode on and off. There was nothing rattling around in the PSU, nothing was stuck in it.
Alright, update. No such noises coming from this PSU’s fan, just as advertised on this review, it is extremely silent. I was shocked at how silent it was. Normal behavior both in hybrid and always on mode. I keep my fan always running.
