This is the same platform as the Seasonic Vertex PX-1200 I reviewed a while ago.
Seasonic is the OEM, and the platform’s design is contemporary. It has a full-bridge topology on the primary side and an LLC resonant converter for lossless switching and increased efficiency. Eight Nexperia FETs regulate the 12V rail on the secondary side, with the same rail powering a pair of DC-DC converters, which generate the minor rails. The PCB is not densely populated, leaving enough space between parts for good airflow. The heatsinks on the primary side are relatively small, as in most high-efficiency PSUs, and tiny on the secondary side.
There aren’t any components on the PCB’s solder side since all of them are installed on the other side, including the 12V FETs. Seasonic used quality parts in this platform, including Toshiba, Infineon, and Nexperia FETs, Chemi-Con and Rybycon caps, and a Hong Hua fan featuring a fluid dynamic bearing. Seasonic also installed many polymer and electrolytic caps on the modular board to improve ripple suppression and transient response. It is always good to see increased capacity on the secondary side because it plays a crucial role in transient response, which the PSU will have to deal with in real-life scenarios where the loads are not steady but constantly change.
Hola cual me recomiendas más la nzxt C1200w o la lian li edge 1200w o esta montech titan pla 1200w?
NZXT C1200
What be better?
Monotech titan pla 1200w or lian li edge 1300w?
Would you consider reviewing some of the sama psus like black diamond, black hole, XP, and even the new upcoming GT series? When they’re in stock they’re at incredible prices, and my buddy who’s working on a psu database says some of their electrical performance is debatably a tier.
Sure why not!
Are there any notable safety concerns when using this as compared to a better reviewed 1200W-1300W PSU with a MSI RTX 5090 SUPRIM SOC?
I already purchased this PSU (felt it was good as it is a Seasonic OEM and there are also very few white PSUs at >1200W)
However I am now concerned after reading the cons listed in this review, and might switch to the [ASRock Taichi TC-1300T] or [Lian Li Edge Gold/Plat 1200W/1300W] if it would improve safety levels
Look at the protection features table, everything you need to know is on this page.
I liked the Taichi units, FSP is trying hard to make them highly competitive.
Thanks for the review crmaris!
Thank you for taking the time to review this unit!
anytime!
