While the C1500 uses the more advanced and semi-digital CTT platform, the lower-capacity members of the same line use the analog CXT platform. The design is contemporary, with a half-bridge topology on the primary side and an LLC resonant converter. On the secondary side, a synchronous scheme rectifies the 12V rail through eight Infineon FETs, and a pair of DC-DC converters generate the minor rails.
All parts are of high quality, and the soldering quality is also good. The cooling fan is by Hong Hua, which dominates the PSU market because of its fair prices, good quality, and performance. The fan uses a fluid dynamic bearing for lower noise and increased longevity.
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.
