Average Noise
The average noise is high, which is expected given the unit’s high capacity and compact dimensions. You can call it super-noisy, though.
Fan Noise & Speed Maps @ 28-32 °C
The semi-passive operation lasts up to 540W, with a minimal load on the minor rails, and with a mid load at 5V and 3.3V, it can go up to 700W, which is 100W higher than the 1000W model. With 780W or higher loads, noise exceeds 30 dBA; with more than 1000W, noise exceeds 40 dBA. Two small regions at high loads have noise output within 45-50 dBA.

Hi again Aris (I previously asked you about choice between this PSU and the NZXT C1200).
Do you know if this Super Flower PSU have a Fan Failure Protection ?
Also, regarding the Power-on time (T1), I understand that the problem resulting from it being above 100ms is that ALPM might not work ? Is that correct ?
Should I be worried about it being 114 ms on this one ?
I found on the Intel documentation for ATX 3.0 that T1 is recommended below 150ms. Did this value changed since then ? maybe with ATX 3.1 ? The only place i found it recommended below 100ms was for the ATX12VO standard.
Or maybe 100ms is symply your recommended value, coming from your experience ?
T1 above 100ms is still ALPM.
It depends on the mainboard about T1, I usually prefer below 100ms but I don’t believe 114ms will be a huge issue.
Fan failure protection, please check the protection features table of the review
Ok, thank you for the explanation. I guess that any problem with such timing can’t be predicted until tried with the specific motherboard I would like to power ?
Do you know of any specific model of MB or brand where a T1 like this could be a problem ?
Regarding the Fan Failure Protection, sure I have beem looking for it in your “Protection feature” part of the review, but this detail is actually missing. Maybe your were not yet trying this feature at the time of this review ?
Thanks again for you great help.
Am I missing smth? I got 2 of this PSUs 1300w and 1000w on 230v. Both got 12v rail dips to 11.704v under 800-900w load while ur test show no dips at all.
and how you found out of this volt dip? Mainboard sensor? Ignore it.
Hey, is this PSU actually compatible with ATX 3.1? They say it is on their home page but the one the box it still says ATX 3.0
Yes. It is. Old marketing material.
Thank you 🙂
no case is included on the current release of this PSU. I think all PSU’s should come with a case/bag. Feels very cheap to see it in this review but not in the retail release.
Not a reason to avoid but something to note. The cables felt a lot less substantial than a msi 1000w unit I was pulling out (DOA unit being returned). The MSI MPG also had nice sleeved cables while this one had more standard ones with very poor QC on the rubber tape/band wrapped around the 12VHPWR. Glue was allowed to seep and dry from the tape and just made everything look sloppy. Not what someone wants to put in their 3-4k PC.
Hm will talk to Super Flower about the missing case.
I needed a high wattage PSU and decided to buy this on Newegg for 185 USD largely based on this review. Many of the 1000W PSU featured on this site was priced 140 USD and often more according to PCpartpickers, so it wasn’t that hard of decision to pay a little extra for this instead.
This is a very goood PSU and the price you got it is also good!
Hi Crmaris,
When will this psu be released in eu?
I cant find a good 1200 watt ATX 3.0 psu in europe.
Nothing comes close to this cpu as far as i know. What should i do or buy tom come close to this psu? Im lost. Biggest factor for me is noise and coilwhine.
Kind regards,
Sam
Casecom used to import SF PSUs in Europe. You could send them an email to check.
For a 4090 build do you recommend this or the 1000w version?
It depends on the CPU that you will use. If you go for a power-hungry CPU, I suggest the 1300W for extra headroom.
When will the 1300W version be released?
Yes, but I don’t have a schedule from SF on this.
Why does it say 12VHPWR connector support but i cant see anyone on the pictures?
It uses 2x 8 pin on the modular panel for the 12VHPWR, which is safer.
