Introduction and Features
Introducing Cyonic – the latest player in the global PSU arena
Introducing Cyonic, a new player in the global PC power supply arena. Founded in 2013, Cyonic’s goal is to become a global brand of high performance computer parts and accessories. The business is starting off by selling power supplies and Cyonic will soon have three product lines: the AU Series (fixed cables), AUx Series (all modular cables), and the Arise Series (sold exclusively in Japan). The AU and AUx Series will both contain three models, ranging in output capacities of 450W, 550W, and 650W. In this review we will take a detailed look at the AU-450x we received for evaluation.
The new Cyonic AUx Series power supplies feature fully modular cables, quiet operation and high efficiency. And they are housed in a compact chassis that measures only 140mm (5.5”) deep. Cyonic suggests the AUx Series power supplies are “the ideal choice for office use, casual gaming, and Home Theater PCs”. Getting into the PC power supply market might seem a rather daunting task, but Cyonic has partnered with Seasonic as their OEM, which is certainly a good start.

• 450W, 550W and 650W models
• Fully modular cables design
• Compact ATX chassis: only 140mm (5.5”) deep
• 80 PLUS Gold certified, at least 90% efficiency under 50% load
• 120mm Fluid Dynamic Bearing fan for long life and quiet operation
• Intelligent Fan Manager for very quiet operation
• High quality components including 105°C Japanese electrolytic capacitors
• Compatibility with Intel's 4th Generation Core processors
• Safety Protections: OPP, OVP, UVP and SCP
• Conforms to ATX12V v2.31 and EPS 2.92 standards
• 5-Year warranty
PSU Testing Methodology
Establishing an accurate load is critical to testing and evaluating a PC power supply. PCPerspective’s power supply test bench can place a precise DC load on the PSU under test. Each power supply is tested under controlled, real-world conditions up to its maximum rated load (at 40ºC), using both 115 VAC and 240 VAC line voltage. Our current suite of tests includes:
• DC Load Regulation
• AC Ripple and Noise
• Differential Temperature
The Cyonic AU-450x power supply was evaluated on both features and performance. A full range of equipment was used to test the power supply under controlled load conditions.
• (2) CSI3710A Programmable DC load (+3.3V and +5V outputs)
• (4) CSI3711A Programmable DC load (+12V)
• (3) 218W Precision resistor load bank (+12V)
• Switchable precision resistor load bank (-12V and +5VSB)
• Agilent 34401A digital multimeter (Accuracy ±0.0035% vDC)
• Extech 380803 Power Analyzer (Accuracy ±0.5% of full scale)
• DS1M12 "StingRay" digital oscilloscope (20M S/s with 12 Bit ADC)
• Powerstat Variable Autotransformer, 1.4 KVA, 0-140 VAC
• Extech Model 407738 digital sound level meter (Accuracy ±1.5 dB)
The following cables/connectors were used to connect the AU-450x to the PCPerspective power supply test equipment.
• (1) 20+4 pin ATX
• (1) 8-pin EPS/ATX12V
• (2) 6-pin PCI-E
• (2) SATA
• (2) Molex
Its always nice to see
Its always nice to see Seasonic being rebranded over some junk brand.
The problem is, like the article says, you can buy a Seasonic branded PSU or even an Antec thats also a rebranded Seasonic(some of them have lit fans to differentiate them from Seasonics standard models) for about the same price.
If they want to charge a lot, they should have Seasonic build their with differentiating features. Custom paints, cable sleeves, monitoring sensors or software like Corsairs Flextronics rebrands, or something to entice people to buy it.
Someone informed enough to know its good BECAUSE its a rebranded Seasonic probably wont buy it over a standard Seasonic without some incentive like that.
I use Antecs Seasonics since they go on sale a lot. Thatd be a good reason for this PSU too.
“The more the
“The more the merrier”, I guess. I just hope that more competition brings prices further down across the globe.
Since it is a rebranded
Since it is a rebranded Seasonic PSU and is 20mm shorter (quite cool actually) I would probably buy one, but it NEEDS to come in cheaper than a ‘known’ brand to sell any units.
As long as more competitors
As long as more competitors on the market outright FORCE Corsair to cut down prices for their GODLIKE RM, HX, and AX PSUs, I’ll be absolutely fine with this.
I hope you realize that a lot
I hope you realize that a lot of the decent Corsairs are just REBRANDED SEASONICS too. The AXi is rebranded Flextronics.
Most Corsairs are rebranded CWT junk and they DONT MANUFACTURE ANY PSUs. They just rebrand.
I know a lot of people trust Corsair since some of their older PSUs were rebrands of good stuff but i usually tell people to stay away from them. Its like G.Skill with memory. No reason to use them and theyre kind of a ripoff since theyre just rebrands of other companies stuff lol.
It’s not “rebranding”, it’s
It’s not “rebranding”, it’s just OEM’ing. These are not same thing. “Rebranding” is when a company either makes a “new” line of products which is essentially re-badged older line (in other words – AMD), OR gets a batch of reference units from some party by default (in example – reference video cards) so that it can sell it under it’s name. Corsair’s relationship with SeaSonic is nothing like that, because Corsair DIRECTLY OEMs from SeaSonic under the long-=term contract. It’s a very well known fact that Corsair OEMs from SeaSonic, and been doing so for many years, this really can’t be called “rebranding” simply because SeaSonic makes units DIRECTLY for Corsair, under Corsair’s supervision and with Corsair’s specific vision on PSUs. This could’ve been called “rebranding” only in the case if SeaSonic was making ABSOLUTELY THE SAME PSUs for EVERYONE out there to whom it OEMs, but they’r NOT doing it in regards to Corsair because they’re working DIRECTLY for Corsair under the long-term contract, so this is not “rebranding” in all actuality. Also, no, Corsair doesn’t OEM 100% of all of their PSU units. Only AX, HX, RM, CS and CX lines. If my memory is correct, TX/VS/VX were in-house products.
Corsair VS is made by Channel
Corsair VS is made by Channel Well Technology.
TX and VX were discontinued, so I have no info on those.
But I am fairly certain that Corsair has never made their own power supplies. Even the Corsair CX that is currently made by Channel Well Technology started out in 2009 as a Seasonic made unit.
AX / AXi series 760w – 1200w Seasonic (AX) / Flextronics (AXi)
HXi Channel Well Technology
RMi 750w Channel Well Technology
RM 850w Channel Well Technology
CS Great Wall
RM Channel Well Technology (450w – 650w, 1000w) / Chicony (750w)
VS Channel Well Technology
Corsair CX / CXM Channel Well Technology
Corsair SF600 (unknown manufacturer)
So based on that info, only the AX series is now made by Seasonic.
I just bought these PSU and my fan is constantly working in around 1000 RPM. I bought because of silence and quality, but l am not sure now, it seems to be something is not OK, can you please help. I thought fan just start in 50%+ usage and can be regulated by own sensors with silence in mind, but that is not the case here, how come is that? My complete PC at full load need 250-300W ( not gaming, its business build, graphic card is R5 230 2gb with passive cooling), daily use is probably 150max, and l bought this AU450 version? What could be the case here? Thank you very much
I don’t know why the author thinks this is a Seasonic manufactured power supply, is it because of the similarity in shape?
Because this is DEFINITELY not made by Seasonic. It features a crappy group regulated design whereas Seasonic Focus series have DC-DC topology (you can’t spot the dual 5V converter coils here). Also the daughter board for the modular connections is connected via internal wires and not wire-free like in a real Seasonic Focus power supply.
I hight doubt that the test results are accurate too.
Seems like a well-made fake product and fake review to boot. Readers beware!
Lee didn’t write “fake” reviews, and he knew what he was doing with the test equipment. Also, when we ask the company “who was the OEM for this” and get a reply, we don’t have to guess who made it. You’re also commenting on a review posted 7 years ago. Keep trying to make a name for yourself in comment sections, “CapsnSpace”.
