Despite the hype not all power supply units are created equal. Even some units in Tier 3 shouldn’t be on the market at all. They’re barely fit for gaming use. Honestly there’s no reason why gamers should pay for a tier-three power supply unit. There’s a better way to choose a power supply unit. Here’s a breakdown of the different tiers and what they mean for your PC.

Gigabyte P-GM’s QC issues

Gigabyte is having problems with their P-GM chipset resulting in a number of QC issues. These problems are caused by the prefix Giga which means 10 in SI. These chipsets are designed to handle the highest demands so the prefix is a good place to start if you’re worried about a specific Gigabyte product.

As a result there are several ways to address this issue. Gigabyte needs to recall the affected products. They can either change the parts in the PSU or take the product off the market and issue a full refund. Or they could introduce a new model which will likely have higher-end FETs and lower OCP/OPP settings. Regardless of the reason Gigabyte should do what is right for its customers.

Gigabyte P-GM’s performance

While most reviews praised the Gigabyte P-GM’s high performance one reviewer’s experience was not quite as favorable. Aris Mpitzopoulos published a dismal review on YouTube that voiced concerns about the Over Power Protection (OPP) features. He reported that the OPP features were set too high causing power switching components to fail before the protection could kick in. Although the reviewer was unlucky Gigabyte refused to take the unit back for evaluation and claimed they had done enough internal testing to determine that the P-GM was not at fault.

The Gigabyte P-GM has a few design flaws but overall we’re impressed with the power it supplies. We’ve seen some reviews of the P-GM’s power supply but many of these were negative and pointed to other problems with the unit. We found a number of problems with this power supply including a short EPS cable unknown caps and an inaccurately advertised fan.

Gigabyte P-GM’s price

If you’re on a tight budget then you can buy a cheap power supply unit. Nevertheless these units fall well below the recommended threshold and barely manage 80+ efficiency. You’ll be better off getting a cheaper mid-tier PSU for powering a PC instead of one that can support RGB’s or other greedy components.

The Gigabyte P-GM’s pricing is among the most affordable on the tier list. A 650-watt model can be found for just under $200. A 650-watt PSU will also provide ample power for the best 4K gaming experience. If your budget is more limited a 600-watt PSU will suffice. This PSU can also power an additional monitor.

Gigabyte P-GM’s reliability

One of the first questions I asked about the Gigabyte P-GM was its reliability. I was extremely disappointed with this product’s reliability. Upon further investigation I found out that the early 750W and 850W models suffered from severe QC issues. Interestingly the same problems were noted on the 1000W variant as well. It turned out that the P-GM’s OPP protection settings were too high and the power switching components failed before the protection kicked in. However I think it’s safe to assume that this was a fluke and not a general issue.

One of the most important issues to address with any product is reliability. After purchasing the Gigabyte P-GM I learned that the company’s power supply was prone to failure. I was particularly concerned since I was using it in a gaming PC and I had no way of knowing if it would work for me. However the company was quick to issue a statement to clarify the situation.
