In addition, the Corsair CX Series PSUs have an unmatched reputation for reliability. That has made them the clear choice for value-conscious PC builders. The 550M and others in the CX lineup are designed in response to users’ requests for a budget modular PSU. However, they’re built to high levels of quality with configurable cables that simplify installation and help PCs stay cool and uncluttered. Over-voltage can lead to unscheduled turn ON of the CX550M or its permanent destruction. Some factors responsible for such incidences are commutation and lightning.

Overcurrent is another aspect under the control of this Corsair power supply. They can be either external or internal. However, Corsair has adequate preparation for such events with built-in measures to curb the impact of excess electrical power, which is a good addition.This proven power supply employs some protection techniques. They include options for overcurrent, Undervoltage, overvoltage, and short-circuit protection. It would help if you operated the power supply within permissible temperature limits so that heat produced at the junctions gets dissipated. Heatsinks are appropriate for such instances. From the box, you get items that lead to a straightforward installation process, but the power supply has one eight-pin CPU power connector, which splits into four each way. If your older system doesn’t have an eight-pin connector, break it and use four of it. Furthermore, you get six Serial ATA power connectors, three Molex power connectors, and two 6 + 2 pin PCI Express power connectors. These are awesome for 1070, 1080, 1070Ti, or a Vega 56. The devices mentioned would work fine using that cable with two eight-pin power connectors. – Modular PSU Sleeved cables, over voltage protection, overpower protection, undervoltage protection, short-circuit protection, single 12V rail, temperature controlled fan, semi-modular Once you’ve installed a PSU, there’s no need to worry about it. At least, that is the case with many power supplies, so this one follows suit, thanks to the thermally controlled fan. It makes the CX Series Modular quieter at idle times, and the large diameter reduces noise even when pushing your system hard. – Overvoltage, Overcurrent, Undervoltage, and Short-circuit Protection

This is a great way to know that the product has been tested at different capacities and can withstand performing during great stress. You can rest assured that it has what it takes to perform at its best. – Thermal Fan

The TX550M is another good PSU by Corsair.

The CX Series features and appearance prove that it was subjected to careful testing by the best hands. The power supply cables are attached to let you connect only the cables you need to configure PCI-E cards and storage devices. The cables won’t add to any clutter or restrict airflow. Besides, the cables are hidden from view when you install the power supply.
