Why are Gigabyte Power Supplies Failing?


The power supply is used to provide power to all the parts inside a computer system. It converts a 220-230- or 110-115-volt AC current into a low-voltage steady DC current. It is usually situated at the top backside of your system. At the front of the fsp460-60glc – Sparkle 460-Watts, you can find a number of cables, which are connected to the computer’s motherboard and various other components. 

These days, we have been listening to news that Gigabytes power supplies are not reliable and are failing. The PSUs are failing, damaging PC components, and even exploding, after which the company is making some adjustments to fix their devices. Also, Gigabyte is offering an exchange and return program.

It had been supposed that the issue comes from OPP, OTP, or OCP all kinds of power supply protection. We were made aware of potential issues of the power supplies at high wattages when tested through DC Electronic Load for extended lengths close to 120 percent to 150 percent. This level of testing can brutally decrease the lifespan of the device and components of a Sparkle 460-Watts fsp460-60glc Power Supply.

OPP is basically the overpower protection, which is a way in which a power supply will defend itself from overloading if it exceeds its max-rated wattage. The trigger point is the value at which overpower protection will shut the power supply off, letting the power supply function at greater wattage.

In a statement, Gigabyte acknowledged all the issues in their PSUs. The company sets a limit at 120% to 150% of the advertised wattage — 900 to 1125Watts for the P750GM. One of the positive aspects is that the company is refunding the amount. But this does not justify all the issues customers and reviewers pointed out.

There have been reports that some customers pointed out that their power supply units were dead when they were delivered to them. A lot of them did not buy those self-sufficiently. Also, some of the customers only got 3000 RTX as part of a bundle.

How can you get your Refund?

The company has updated its website along with the guidance on how you can refund your payment. The guide involves step-by-step instructions on how to apply for the Refund. So, after seeing all the Gigabyte’s situation, one can question how to protect their computer from power surges and fluctuations?

  • To protect your computer system, you can use surge protectors as they are one of the easiest and quickest ways to protect electronics from power surges. Occasionally, these are known as power strips because they can protect your system from getting damaged due to a power strike. It helps by diverting power when there is a power surge, preventing electricity from being sent to electronic devices. These are required to be tested to make sure they are doing their job.
  • To protect your system from getting damaged, the best you can do is unplug your computer system if you feel there is a power surge. Computer users and IT professionals recommend this practice as the best way to protect yourself from the damage caused by a power surge. In case of severe weather, it is best to unplug all of your electronic devices, including computer systems.

Why Do Power Supplies Fail?

A power supply is a component that remains under the most stress because it is the power-conversion bridge among the main grid and the system’s components. It means that the Gateway 730 Watts DPS-730ab has to deal with all the abnormalities of the mains. In low-quality power supplies, the cooling fans and the electrolytic caps are the parts that tend to fail. But we will also discuss the reason behind the failure of a top-class power supply.

  • Multi-Layer Ceramic Capacitor Issues: The major reason behind the failure in quality PSUs is cracked MLCCs. In fact, a single broken MLCC can cause a power supply failure. The cracks can happen due to; improper PCB stacking, PCB bending during the solder-wave procedure, and careless soldering repairs.
  • MOSFET and IC Damages: If the applied heat is high and the manufacturing line is set at higher, then there can be minor or fatal damage to MOSFETS, and ICs, both of which can eventually cause the power supply failure.
  • Current Surges: High currents caused due to transient energy demands are known as inrush currents. Current surges and high voltage can be the cause of several component failures, counting rectifiers, fuses, and diodes.
  • Cracked PCBs: the PCB can be cracked during shipping, which ultimately results in PSU failure. This is the reason the protection of the unit inside the box is important. Packing foams are the best accessories to protect your exclusive power supplies while shipping.

To summarize, we can say that high-quality power supply units can fail due to the below-mentioned reasons

  • Cracked PCBs
  • Broken MLCC components
  • Damaged ICs and FETs
  • Long mounting PCB screws
  • Careless soldering jobs/repairs
  • High inrush currents
  • Cracked PCBs
  • High surge voltages
  • Creepy-crawlies

You should keep bugs away from the system and employ a UPS, and it can help protect the PSU from voltage sags, brownouts, and surge voltages. Also, the use of quality PSU is vital if you live in an area with an unstable main grid.
