If you have been following the recent drama of GIGABYTE selling exploding power supplies, then you are aware of the happenings with GIGABYTE response, our PSU expert's response, and of course the massive backlash from customers. Today, according to a Reddit user u/Tinefol, GIGABYTE has refused to RMA the power supply that is eligible for the RMA program. The user is an owner of the GP-P750GM unit, which is part of the exploding units. He proceeded to open a ticket where he included the wordings from the company's press release, to which he got a response that "This press release is applicable only to the newer batches".

However, that is not the case. The press release states that GIGABYTE will offer RMA service on various models with the supported serial numbers. In the case of GP-P750GM PSUs, the RMA service is available for units with serial numbers ranging from SN20243G001301 to SN20453G025430. The customer that requested RMA has serial number SN20243G001306, which is eligible for return and exchange. The ticket response of "This press release is applicable only to the newer batches" holds no value as the press release does not refer to production time, but rather serial numbers of PSUs.

Cybenetics certification program's chief engineer, a renowned expert with switching power supplies, and TechPowerUp contributor, Dr Aris Mpitziopoulos, released detailed commentary on the recent statement released by GIGABYTE on the GP-P750/850 GM series PSU design flaw reportage in the press. The earliest of this was broken on TechPowerUp, with our December 2020 review of the GP-P750GM, which led with the headline "With an Explosive Attitude."

Mpitziopoulos dives into the technical details of the design flaw being not just a badly programmed Over-Power Protection (OPP) safety mechanism, but a flawed hardware design overall. Since he reviewed PSUs from this series for TechPowerUp and Hardware Busters, he shares his perspective on how the reviews went, more importantly, the back-and-forth with GIGABYTE when the flaws were discovered.The following is a statement by Aris Mpitziopoulos:

GIGABYTE is aware of certain media outfits casting doubt over the quality of Power Supply models GP-P850GM and GP-P750GM. GIGABYTE takes pride in the design and quality of our products and as such, takes reports of this manner extremely seriously and therefore would like to address the reported potential issues as follows:

For desktop PC systems, there can occasionally be instances where the peak wattage can exceed the intended usage range. During such instances, the GIGABYTE GP-P850GM / GP-P750GM model power supplies include the industry standard built-in safety feature "Over Power Protection" (OPP). The OPP safety feature is designed to shut down the unit when the power load exceeds the wattage the unit was designed to operate within. The OPP was set to 120% to 150%, 1020 W~1300 W for GP-P850GM, and 900 W~1125 W for the GP-P750GM.

Intel's upcoming Alder Lake family of processors, more specifically the desktop ALD-S SKUs, are supposedly going to require a higher peak current for the upcoming processors. In the table provided by the Chinese tech media outlet, FCPOWERUP, we are seeing that ALD-S processors have different power requirements for the ATX12V rails on their power supplies. The listed table shows the previous generation of Intel processors, the 10th and 11th generation, as available in 165 Watt variants. Even though there are no 165 Watt Comet Lake and Rocket Lake SKUs, this is only a placeholder for their PSU recommendations in case those SKUs were to be released.

According to the table, the peak current recommendation for the upcoming Alder Lake is higher at least 5 Amps across all SKUs. The 165 Watt SKUs have the requirement of 45 Amps (compared to the 40 A of Comet Lake and Rocket Lake), while the 125 Watt SKUs require 39 Amps, which is higher than the previous 34 Amp requirement. For 65 Watt models, the new peak recommendation is 38.5 Amps, a jump from the previous 30 Amp choice. The lowest rated 35 Watt SKUs are recommended to use 20.5 A, while the previous generations used 16.5 A current. It should be noted that the continuous rating has not been changed (new generation 35 Watt models actually use less current), which indicates that Alder Lake could have higher peak usages of power, meaning that PSU choice should be made with a 50-100 Watt higher rating.

GIGABYTE introduced its flagship power supply lineup, the AORUS P-series. Completing your collection of AORUS-branded motherboards, graphics card, memory, SSD, and cooler, the P-series is debuting with a 1200 W model, the AORUS P1200W, and its star attraction has nothing to do with power. The P1200W features a 4-inch true-color LCD display that puts out real-time power stats (input voltage, power-draw, temperature, etc.,) but can interface with software over USB (an internal USB header), and can be made to display just about anything.

As a PSU, the AORUS P1200W features a single +12 V rail design, 80 Plus Platinum efficiency, APFC, DC-to-DC switching, fully modular cabling, 100% Japanese capacitor design, and most common electrical protections. The unit is cooled by a 140 mm double ball bearing fan that stays completely off under 240 W load, maintains 20% speed up to 720 W, and only ramps up beyond that. Connectors include a 24-pin ATX, two 4+4 pin EPS, ten 6+2 pin PCIe, sixteen SATA power, and four Molex. The company didn't reveal pricing.

Intel's 12th Generation Core "Alder Lake-S" desktop processor will see a limited launch in 2021, according to an Igor's Lab report. This will be restricted to PC enthusiast-relevant SKUs bearing the -K and -KF brand extensions, and compatible Socket LGA1700 motherboards based only on the top Z690 (Z590-successor) chipset. The series will ramp up to other (locked) models, along with more affordable chipset models (B560-successor), only by Q1-2022, on the sidelines of the 2022 International CES. Sources tell Igor's Lab that these select few models could be launched between October 25 and November 19.

Intel is expected to make several technological leaps over AMD with "Alder Lake-S." To begin with, it has the first hybrid core technology that combines high-performance "Golden Cove" cores with high-efficiency "Gracemont" cores, in a heterogenous multi-core setup comparable to Arm big.LITTLE. Next up, it is expected to debut the PCI-Express Gen 5 I/O, and DDR5 memory support. While PCIe 5.0 GPUs remain under development, the first devices to take advantage of it are expected to be NVMe SSDs, benefiting from 128 Gbps bandwidth (Gen 5 x4). It is also learned that the next-gen motherboards will retain the current ATX 24-pin + EPS power interface, and Intel won't force adoption of ATX12VO. The new ATX12VO standard increases motherboard costs as it essentially transfers DC-to-DC switching components from the PSU to the motherboard (12 V to 5 V; 12 V to 3.3 V, etc), and adds output connectors.

In response to reports of the PCIe riser cable of its H1 case posing a fire hazard, NZXT in February 2021 instituted a recall of the case in the U.S. and Canada. The flaw in the component's design came to light in early-2020, but it was only by November that it responded to the issue. In its original design, the PCIe riser component was improperly grounded, and a short-circuit could result in a fire. NZXT's first response to this was sending out non-conductive Nylon screws for the users to replace the metal ones the part originally shipped with. This solution wasn't found to be effective, and resulted in a product recall this February. Regulators in the U.S. and Canada directed NZXT to send out free repair kits to existing owners of the H1, along with disposal instructions for the entire case, if the user wishes to discontinue use. We got our Repair Kit, and decided to go hands-on.

The NZXT Repair Kit, and replacement riser card appears to be one of the most solidly built PCIe risers in the market. Thanks to the crypto-mining boom, the market is flooded with PCIe risers of all shapes and sizes, and the NZXT riser looks to be among the better designed ones. What sets this apart from the original design is that now, the downstream (female end) of the riser comes with grounding rings around the mounting holes, similar to motherboards. These are bits of exposed copper that facilitate contact between the ground layer of the PCB, with the sheet-metal of the case. The original design lacked grounding pads on either side of the PCB, and when installed with metal screws, certain PCB traces could get shorted, causing them to heat up and start a fire. NZXT's first solution to this problem was non-conductive Nylon screws. End users with an H1 case, can request this riser cable from here.
