Gigabyte’s GP-P850GM and GP-P750GM power supplies have been wandering around in the hardware circle for various unfavorable reasons. Obviously, the failure rate of these two models is very high, and it may be a time bomb of the car owner. Gigabyte issued a statement Introduce solutions to problems reported by users and news media in detail.
Consumers who made a successful purchase GeForce RTX 30 series In recent months, the (Ampere) graphics card from Newegg may have heard of or owned the GP-P850GM or GP-P750GM. The retailer paired Nvidia’s RTX 30 series graphics cards with one of the above-mentioned power supplies as part of the bundle, so Ampere adopters must purchase power supplies with graphics cards whether they need it or not.
Neither GP-P850GM nor GP-P750GM have a good reputation on Newegg. Among 92 consumers who purchased GP-P850GM, 39% of the user group left an egg score. The feedback from GP-P750GM is even more shocking. According to Newegg, 53% of 305 buyers left the lowest rating.The two most common complaints are defects and premature failures upon arrival, which in some cases will quickly die and take away other components
according to Player Nexus, 50% of the 10 power supplies failed during or after the over power protection (OPP) test. Some units failed at 60% load after the first pass. The publication also conducted a survey of its community, in which 16% of users claimed that their power supply had failed and was no longer operating.

|Last OPP trigger point||New OPP trigger point|
|GP-P850GM||120% ~ 150% (1,020W ~ 1,300W)||110% ~ 120% (950W ~ 1,050W)|
|GP-P750GM||120% ~ 150% (900W ~ 1,125W)||110% ~ 120% (825W ~ 925W)|
Aris Mpitziopoulos, our resident power expert, in his points Nemesis YouTube channel, his sample exploded in fireworks. Mpitziopoulos concluded that the OPP and OCP protections were set too high and the FET in question could not handle the load at all.
Gigabyte’s solution includes reducing the OPP trigger point of GP-P850GM and GP-P750GM. The manufacturer lowered the threshold from 120% to 150% to 110% and 120%. Gigabyte reiterated in its statement, “The reported potential problems seem to occur only after a long period of extreme load testing with DC electronic load equipment, and will not be typical of any real-world use.”
Gigabyte claims that the old and new OPP thresholds are suitable for daily use. Nevertheless, if the standard is met, the company is willing to provide the owner with a revised unit. GP-P850GM with serial numbers SN20343G031011 to SN20513G022635 and GP-P750GM with serial numbers SN20243G001301 to SN20453G025430 can be exchanged.
However, we do not believe that adjusting OPP protection is the answer to the problems of GP-P850GM and GP-P750GM. Most of Newegg’s user feedback involves DOA (Death On Arrival) units, so this may be a design issue, or the quality assurance department may fail due to a few issues, and a batch of bad batches may escape from the factory.
