Review: Efficient and reliable power - Used this on another build before. I bought it for the high efficiency rating which helps improve thermals and generally indicates good build quality. Happy with the performance and have not run into any issues or overly loud fans. It would be nice if there were some PCI power cables that did not include a second power head but it does make it easier to run just 1 cable instead of 2. Plenty of power ports to support most builds. The dimensions should work for most ATX builds.
Review: Very quiet, was recommended by Tom's Hardware - This review is for: XPG Core Reactor Modular PSU: 80 Plus Gold - ATX - Fully Modular Power Supply - 10 Year Warranty - 650 Watt. Overall: Quiet. Stable power. Tom's Hardware recommended. Due to the CPU line's length, would probably recommend another power supply if you want/need to route through a backplane. Otherwise won't be an issue. Review: A Tom's Hardware PSU review had this listed as a recommendation, so I bought it. Technically it was my second choice but seems to be good quality. My previous power supply was quite loud with a 30% load, but this one is very quiet. I do wish the CPU power cable was longer though. The non modular cables are also pretty stiff. I ended up having to route the CPU cable over the mother board instead using the backplane. My system hasn't had any stability issues. I mention this because the PSU is one component to not skimp on. Even decent brands can have problems with power dips, consistency on the various rails, or ripple. If I had to go back, I would probably choose another power supply with a longer CPU line. However, if you don't need to route cables on a backplane, it won't be an issue for you.

### ⭐⭐⭐⭐⭐ Awesome PSU at reasonable price point. Modular goodness and quiet.
*by R***C on March 1, 2025*

Used in a new build with Ryzen 5 4500 and other assorted goodies. Have no complaints about this PSU. Have been running the new system about a month now and it is quiet and delivers the power without issues. The cables can be stiff so be aware of that. I really like the modular hookups and the carrying bag for unused cables. It's a great Power Supply so far.
