Silicon Memories Silicon Memories · channel Exactly 10 months after buying this Power Supply (PSU) "Gigabyte P750GM 80 Plus Gold" the unit gave a loud band sound and burned off. Was a bit late in recording, initially entire room was filled with smoke. I immediately shut the power supply took my kids out the room, then opened windows and let the smoke clear. Then I looked, the power supply burnt, the fan in it broke with oil in it seeping outside, dripping from itself and into the cabinet.Watch G

Avoid budget power supplies that lack proper certifications and protection features, particularly some Gigabyte models like the GP-P750GM which experienced 50% failure rates and catastrophic malfunctions.

The Gigabyte GP-P750GM and GP-P850GM power supplies were flagged after reports of units failing under extended high load testing. Gigabyte lowered the Over Power Protection trigger point and offered a return and exchange for affected serial numbers, though they say it wouldn’t occur in typical real-world use. Many users now recommend Corsair or Seasonic instead.View post
