I bought this for a recent build. I love the 80 Plus Gold rating! This thing looks great, isn't loud, and love the modular aspect of it! 850w is enough to handle most needs. This pushes a 3060, Ryzen 9, 6 case fans, and a ton of peripherals without skipping a beat! Super happy with my purchase!

Purchased back in July of 2023 for a 13900 + 4090 build which is... thirsty for power This thing is a tank, no issues whatsoever - notably and especially nothing to report during the whole 13th gen power draw debacle. I was hesitant to grab a PSU for such a premium build from a company that doesn't rhyme with Smorsair or Smeasonic but I'm pleased that I did! The literature and online information is adequate to get set up and the modularity is decent. The cables aren't quite what I'd call "premo", however one can find a myriad of solutions here on Amazon or elsewhere for sprucing up their aesthetic. At the end of the day you need clean, consistent power provided to your components and this PSU does the job! Highly Recommend

My old beloved Corsair850 blew in my old PC from a lighting storm, so I wasn't particularly looking forward to the cost of having to replace it. Came across this unit, read some reviews, and placed my order. First of all, I could care less about lights and stuff like that. Not my thing, but this was actually kind of cool and nifty. Unit installed like a charm, and once connected, everything worked perfectly and as it should. I was impressed the unit also came with a "dummy plug" for pre-testing the 24-pin connector. I had never seen that before. Changing colors is quite easy as well. There were PLENTY of cables for various connectivity options - whether you are using newer components or older 4-pin power cables. All in all, the unit is a great value for the money, and...it's QUIET!! No obtrusive fan noise! I would highly recommend this unit!

I've had this PSU since 2020 and I haven't had a single problem with it since!! Also the RGB is super cool :)

**UPDATE 2/22/2021 - I ended up disputing with my credit card servicer to get my money back. PSU is still a POS and doesn't even make a decent doorstop. Pulled the PSU apart and the filters are cheap Chinese garbage and are bulging from the bottom. Decided to use it for target practice instead. **UPDATE 12/30/2020 - I replaced this power supply with an ACTUAL 80+ Bronze Cooler Master PSU. Resolved all my issues i had with stability and random shutdowns. I looked into the chassis of the PSU and the caps are bulging. It smells horrid (like ammonia). The company is impossible to get ahold of and they have not responded to my emails nor my calls (they have a foreign number, and i used a Cantonese speaking friend to translate. No response. Only buy this if you're willing to risk damage to your components. I thought I would cut costs with a new build (Ryzen 7 2700 & RTX 2070 with 32GB 3600mhz RAM) since this power supply said it was 80 Plus certified. Worked great and noticed that it “almost” reached the same core clocks that my older TT power supply had. After a while the overclocks became more unstable and I kept pulling the frequency back for cpu and gpu. Now the power supply just cuts off randomly. It will drop voltage significantly to the CPU 8 pin and then cut off. Tested with multimeter and another power supply. Seems like the components used aren’t built to last. I will eventually pull it apart to see if I can see bulging filters. NOTE: I had this power supply pulling fresh air from the outside of the chassis from the bottom with ample space. I’m in a non-smoking house with pets. The power supply air intake is filters with a mesh filter I installed. There is no dust choking the intake (pertaining to this review) I would avoid this product. It was also disappointing it has two pci e spots for gpu/addl cpu but they only provide one cable for pcie power. Save yourself the trouble and spend a little more to get a way better deal. There isn’t even phone support in the United States. You have to call out to Asia. Installation was okay but the connectors are cheap and will chip ( happened to two of my sata connectors and had to tape them with electrical tape to prevent shorts). The clips to lock onto the female connector also are weak and you have to force them to close and ‘’marry”. The RGB effect isn’t controllable except for turning it off (you hold the ECO button for 5 seconds) but it won’t hold that setting after you turn off the pc. Same with the ECO mode. Please avoid this power supply.
