★★★★★PC Power Supply
This PC power supply is stable, efficient, and runs quietly. It delivers consistent power with good cable management options. Easy to install and reliable for both everyday use and gaming setups. A dependable choice for any build.

★★★★★Great purchase
I've read a few of the reviews here, pretty much after I had already bought it. I seen the price, checked the psu tier list and this was rated good on there so I purchased it. It's been like half a year in a build and is doing great. The cables aren't as beefy as my NZXT 1000w psu, but the awg is sufficient for the wattage and quite frankly much easier to route for cable management. Granted it's probably right at half load as it's build consists of a 10700 and rx580. All in all I recommend this psu.

★★★★★Rock-solid stable
I’m running this power supply with a system built around an AMD Ryzen 7 9700X and Radeon RX 9070 XT. During stress testing with Prime95 and FurMark, a Kill-A-Watt confirmed that my system draws up to 446 watts from the wall. The cable lengths work perfectly for my compact white Jonsbo/Jonsplus Z20 micro ATX case. Every cable reaches its target neatly, allowing for clean, organized routing. Additionally, the embossed cables mimic the look of braided sleeving without any added bulk, which is ideal for cases with limited cable management space. Installation was easy. My Z20 case has 140mm fans installed up top, and this power supply is compact enough to fit above a long video card. Each of the two PCIe cables comes with an additional connector daisy-chained at the end—something I typically avoid. However, the extra length provided by this design means the connector can be routed out of sight effortlessly. The unit is exceptionally quiet. There are no unusual electrical noises, and even with my fans tuned for low noise, the power-supply fan remains undetectable. Having never used a darkFlash power supply before, I chose this model based on other customer reviews and its modern feature set. After days of stress testing, its build quality and rock-solid stability have truly impressed me. I’m very happy with my decision to pick this one, along with the value price.
