Although it doesn't achieve ground-breaking performance, the TX650M is a solid choice thanks to its high build quality, quiet operation, and compact dimensions. Corsair didn't go cheap at the internals, trying to save money only with the pair of permanently attached cables, which are the essential ones (ATX and EPS). Moreover, this PSU comes with an adequate number of connectors, including two EPS and four PCIe connectors, supporting power-hungry CPUs, and a pair of mid-level GPUs. It would be great, of course, if all the cables were modular, but this would affect the cost and bring the TX650M close to the RM650x, creating internal competition. The TX650M would be close to the RM650x in average performance with improved transient response and even better ripple suppression.
If you don't mind the pair of non-removable cables, the Corsair TX650M is an excellent choice for a mid-level gaming system. It might not be on top of our performance charts, but users wanting something reliable and not expensive usually care most about performance-per-dollar, plus reliability. Another major asset of the TX650M is its quiet operation, rated as Cybenetics A- (25-30 dBA average noise output), even under harsh operating conditions. If you don't mind spending a little more though, you might want to take a look at the Corsair RM650x or the XPG Core Reactor 650W.
