Seasonic provides the platform, featuring a contemporary design with a full-bridge topology on the primary side and an LLC resonant converter for reduced energy losses. There is enough space between parts on the PCB to allow for good airflow. The primary heatsink is large enough; the same goes for the heatsinks handling the 12V FETs on the PCB’s business side. The interesting part of this design is that no components are installed on the PCB’s back side, not even the 12V FETs.
As already mentioned, on the primary side, in addition to the APFC converter, a full-bridge topology is used, supported by an LLC resonant converter to reduce energy losses. On the secondary side, eight FETs regulate the 12V rail, which feeds a pair of VRMs to generate the minor rails. Well-known Japanese manufacturers make the filtering caps, so the warranty is that long. Moreover, the cooling fan is by Hong Hua and uses a fluid-dynamic bearing for lower noise and increased reliability.

Here is a comparison between the PCCooler YS1200 PCB and the Seasonic Vertex GX-1200 PCB. As you can see, the platform is the same, only the PCB color is different, but that doesn’t play any role.
The transient filtering stage contains all the necessary components to block both incoming and outgoing EMI emissions. Typically, it starts at the AC receptacle and continues on the main PCB. It also includes a discharge IC for its X caps to provide a slight efficiency boost.
There is an MOV to protect from voltage surges and an NTC thermistor with a resistance of 5 ohms. Moreover, a bypass relay supports the NTC thermistor.
The parallel bridge rectifiers convert the incoming AC signal to a loosely regulated DC voltage.
The APFC converter uses two Toshiba TK31E60W FETs and one CREE C3D10060A boost diode. Nippon Chemi-Con manufactures the bulk capacitors. Their combined capacity is 1150 μF, and both are rated for 2,000 hours at 105 °C. The voltage rating is 420V, which is higher than the APFC’s DC bus voltage (approximately 380-400V DC).
The APFC controller is a Champion CM6500UNX.
Four Infineon IPA60R180P7 primary-switching FETs are used in a full-bridge topology, and an LLC resonant converter is employed for enhanced efficiency.
The LLC resonant controller is a Champion CU6901VPA.
The PSU’s main transformer. One of its main functions is to electrically isolate the primary and secondary sides.
Eight Nexperia PSMN1R0-40YLD FETs regulate the 12V rail.
Two DC-DC converters generate the minor rails. They use six Nexperia PSMN1R0-40YLD FETs. The PWM controller is an Anpec APW7159C.
Chemi-Con, Rubycon, and Nichicon provide the electrolytic capacitors. FPCAP and Rubycon make the polymer capacitors.
You can find more information about capacitor performance and other specs below:
The standby PWM controller is an Excelliance MOS EMB8569C.
Many polymer and several electrolytic caps on the face of the modular panel form an extra ripple-filtering layer.
The supervisor IC is a Weltrend WT7527 (OCP, OVP, UVP, SCP, PG).
The soldering quality is fine, but there is nothing else to see on this PCB side!
The cooling fan is a Hong Hua HA13525H12F-Z, utilizing a fluid dynamic bearing.
Will you doing a review for the YS1000W version as well?
Hello Aris, i saw something strange in my country psu market, The Gamdias Helios P2 1300g & 1000g has cybenetics gold certification in the units sold in my country, but there’s nothing in cybenetics database about this brand
I have to send another note to Gamdias, as it seems, because they keep on using Cybenetics ratings without having them! Thank you for letting us know!
I hope they sent units for real certification in cybenetics… I also hope Redragon and risemode send units for certification. I don’t buy psu without cybenetics certification
Look it . I saw it, I thought it strange

Hello Aris, it seems that your review of the NZXT C1200 and C1000 is not accurate. The specifications on the Cybenetics site for the NZXT C1000 are listed here https://www.cybenetics.com/evaluations/psus/2448/, but on HW Busters it looks different; that is the NZXT C1200 https://hwbusters.com/psus/nzxt-c1200-atx-v3-1-psu-review/. I hope you can revise it soon. I am also waiting for news on several pending Cybenetics certification, such as the MSI A1250GS and some Gamemax Lioncore PSUs.
Hi Alex, what is wrong? It is typical of me to do some typos in the specs, but please point out what is different to save me some time.
because on your review on hwbusters the part analysis it’s should be NZXT C1000, just rechecked that NZXT C1000 should using this : https://hwbusters.com/psus/nzxt-c1000-atx-v3-1-psu-review/3/

based on this data NZXT C1000 on the cybenetics web should use this data, and that NZXT C1000 parts description data on Cybenetics web should belong to NZXT C1200
it seems your just misconfigured the parts description NZXT C1000 on cybenetics and using NZXT C1200 data, i see that you also don’t put the parts description of NZXT C1200 on cybenetics web, maybe you can revised up later
thank you, fixed it!
Is the review for the Hxi 1500 further delayed? Could you give me a rough estimate of when it might be ready?
into next week most likely.
So until Friday?
