Average Noise
The average noise output is low.
Fan Noise & Speed Maps @ 28-32 °C – 115V
The fan’s speed is low at up to 620W at 12V, so noise output is below 6 dBA up to that load level. The load on the minor rails generally affects the fan speed, but not significantly. The 30 dBA mark is passed at around 890W at 12V, and there are some small periods, under full load, where the PSU’s noise exceeds 35 dBA.

The fan speed profile at 230V is almost identical to that at 115V. The only slight difference is that the 6-10 dBA region is larger at 230V.

Hello,
In a previous article you’ve mentioned that “ATX v3.1 PSUs are NOT ATX v3.0 because of the lower hold-up time”. However from my research, most manufacturers describe that the new spec is backward compatible. Maybe they are referring to connector compatibility, but given the results for this PSU, which provides hold up time around 30 ms, do you think that it will be possible to pair it with existing ATX3.0 GPUS until upgrading to NVidia 50x series or similar?
Thanks in advance for your response.
I don’t know to what they refer, but the fact is that the ATX v3.0 spec is tougher in hold-up time. Also this PSU yes, you can use it with any upcoming GPU, since the cable remains exactly the same (12VHPWR or 12V-2×6)
Would this be a better choice than the Super Flower VII Gold?
Hi! Thanks for your reply! I appreciate it!
Very impressive work! Thank you very much! 🙂
I was wondering if you heard anything about the Straight Power 12 from be quiet? I have barely heard about this unit and I was hesitating between the Straight Power 12, a Corsair RMx/e or a NZXT C Gold for an RTX 4070 ti Super + i5-14600K system (850 – 1000W range).
Thank you againt!
I haven’t checked it so far, SP 12.
