The major differences with the 1000W model are the primary FETs, which are stronger in the 1300W model, the larger bulk cap (800uF vs. 680uF), and the larger amount of FETs for the regulation of the 12V rail (6x Vishay vs. 8x Infineon). The electrolytic filtering capacitors are the same. The 1300W model uses the same brand of polymer caps with a slight difference in the number(26x vs. 25x). Lastly, SF used the same cooling fan in this unit, which is strong enough to meet the increased thermal loads. Overall, the build quality is high, and SF also used top-notch parts to ensure reliability through time. I don’t have any information on the FDB fan since I haven’t met it before in another PSU brand, but from the testing experience, it looks to be good enough, not as good, though, as Hong Hua fans with similar specs.

  1. 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

  2. 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.

  3. 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.

  4. 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
