Average Noise
The PSU’s average noise output is high, above 30 dBA, at both voltage inputs. However, as shown in the respective charts, this is the case for most high-power units.
Fan Noise & Speed Maps @ 28-32 °C – 115V
The semi-passive mode lasts long enough with a moderate load on the minor rails. The PSU’s noise remains below 20 dBA at up to 640W (at 12V) without any load on the minor rails, which is unrealistic. With a 20-50W load on the minor rails, the PSU’s noise remains below 20 dBA at up to 790W at 12V. Generally, the fan speed profile has many steps, which is good, and it gets aggressive, meaning it is above 30 dBA noise at loads exceeding 780W (at 12V).
Fan Noise & Speed Maps @ 28-32 °C – 230V
The 230V fan noise profile has minor differences compared to the 115V one. The >45 dBA fan operation is restricted at 230V, helping achieve a lower average noise output.
What differences Leadex III and Leadex VII series have?
different platform
Do you think the 1000w version of this PSU is good? There’s no reviews on it
Should I buy Super Flower Leadex III 1300W ATX v3.1 or Cooler Master MWE gold v2 1250w to be on safe site about 2vsb rail?
SF told me that they will fix the 5VSB OCP.
thank you for replying! what about NZXT c1000 atx3.1 or Corsair RM1000e? NZXT c1000 atx3.1 is just few dollars more at my country
I got this PSU but I think mine is dead. Tried doing a BIOS flashback with just the motherboard and cpu power plugged in and nothing happened (yes the psu was switched on). I then did the paperclip test and the fan didnt spin but im not sure if it normally spins at startup. Does anyone know? I tried both with ECO on and ECO off.
with ECO off the PSU’s fan should start.
Thanks for your review. Any thoughts on what you’d pick between the 1000W version of this and the new (ATX 3.1) RM1000x that you reviewed in September?
I am also looking at the Leadex VII XP Platinum that you recommend in your guide. But I think this review is the first time anyone has looked at one of the new ATX 3.1 Leadex III models.
The difference in Wattage us huge between these two, 300W. If you need more power, the Leadex III.
Aris do you have any info for Asrock PSU ?
Yes. FSP and HEC OEMs.
