Newegg Shuffle apparently bundling "explosive" Gigabyte PSUs with GPUs

Newegg is apparently bundling the Gigabyte P750GM and the P850GM power supply units (PSUs) alongside the graphics cards that it is offering via its Newegg Shuffle drawing system for choosing potential buyers.

While this wouldn't be a cause for concern under general circumstances, the P750GM and the P850GM PSUs, however, have been found to perform rather poorly in multiple expert reviews, for example, by TechPowerUp via Hardware Busters (YouTube), and by Gamers Nexus (YouTube). So, with Newegg now apparently bundling these SMPS models with generally power-hungry high-end graphics cards during its Shuffle, it seems there couldn't be a better recipe for some disaster.

Gigabyte has stated that these PSUs feature all the standard protections that are expected in a well-made SMPS, namely:

  • OVP (Over Voltage Protection)
  • UVP (Under Voltage Protection)
  • OPP (Over Power Protection)
  • OCP (Over Current Protection)
  • OTP (Over Temperature Protection)
  • SCP (Short Circuit Protection)

However, it has been noted today by Gamers Nexus (GN) that at least some of these protective features would often fail to trigger in response to such incidents during the lab stress testing leading to several of the GP-P750GM and GP-P850GM units blowing up in the process. The image above demonstrates an example of such an instance where the protection wasn't triggered and the stressed PSU caught fire in GN's lab.

This notorious nature of the Gigabyte GP-P750GM was first brought to attention by YouTuber Hardware Busters via TechPowerUp, who reviewed the model last year and wasn't particularly impressed, referring to the model as "A Power Supply with an explosive attitude".

In the conclusion section of the review, the cons of the unit far outweighed the pros. Here are the points that were listed in its cons:

  • My sample ceased to work during OPP evaluation

  • Over power protection is not properly set

  • Lousy transient response at +12 V and 3.3 V

  • Low-quality FETs on the primary side

  • Unknown caps on the secondary side

  • They advertise an HDB fan, but I found a rifle bearing one instead

  • Very low efficiency with 2% load

  • Low efficiency at 5VSB

  • Hold up time below 17 ms

  • Power ok signal not accurate

  • EPS cable should at least be 650 mm long

  • Short distance between peripheral connectors

  • Not fully compatible with the newest ATX specification (v2.52)

And today nearly nine months later, it seems these issues still exist in the P750GM and P850GM, according to GN. Apparently, Gigabyte has done little to address these concerns. And while faulty PC components shouldn't surprise anyone, it really is worrisome in this instance since Newegg is apparently pushing these out to users as part of the Newegg Shuffle package.
