Gigabyte UD1000GM PG5 & UD750GM 80+ Gold Power Supply Impressions – Solid Solutions For Your New Gaming PC

Gigabyte is a name that is relatively new heard in the PSU (Power Supply Unit) segment however they have deep roots within the market with several offerings dating back to the early 2010s. The previous lineup has been a mix of both high-end and generic offerings but only recently has the brand decided to streamline its offerings into various segments which include AORUS, UD, & the more standard ‘P/G’ offerings. While AORUS offerings are the more premium designs, the UD line comes with some of the more cost-effective offerings. The UD branding stands for ‘Ultra Durable’ which has been Gigabyte’s design philosophy for generations now. Today, we will be taking a look at not one but two of the latest UD series PSUs from Gigabyte, the UD1000GM, and the UD750GM.

Gigabyte UD1000GM PG5 & UD750GM 80+ Gold PSU’s Specifications

Coming straight to the specifications, the Gigabyte UD1000GM PG5 is rated at 1000W while the UD750GM is rated at 750W. On the high level, both of these PSUs feature similar specs, featuring an Ultra Durable design that is composed of Main Japanese capacitors, an enhanced thermal heat sink solution, a 120mm smart hydraulic bearing (HYB) fan, and a range of protection that includes OVP (Over Voltage Protection) /OPP (Over Power Protection) /SCP (Short Circuit Protection) / UVP (Under Voltage Protection) / OCP (Over Current Protection) / OTP (Over Temperature Protection).

Once again, both PSUs are based on the 80+ Gold standard and offer a fully modular design, and a powerful single +12V rail, all in a compact design that is backed by a ten-year warranty. The 80 Plus Gold rating ensures delivering 90% efficiency at 50% load. The output current for the 1000W unit is rated at 83.3A (+12V) for a maximum combined wattage of 999.6W while the 750 unit is rated at 61 Amps (+12V) for a maximum combined wattage of 732W. Both units are also Intel ATX 12V v2.31 compliant.

So rounding up the features we just stated above, the Gigabyte UD PSUs offer:

  • Ultra Durable
    •  Main Japanese capacitors
    •  Enhanced thermal solution
    •  120mm smart hydraulic bearing (HYB) fan
    •  OVP/OPP/SCP/UVP/OCP/OTP protection

As for the design of the PSU unit, both come in an ATX form factor and measures 150 x 140 x 86mm. Gigabyte calls this a compact design than standard PSU offerings which allows easier installation in almost any PC chassis without worrying about space constraints. Moving over to cooling, the compartment is outfitted with a single 120mm smart hydraulic bearing (HYB) fan, offering a 1.4x longer lifetime compared to standard sleeve bearing fans. As for acoustics, the hydraulic fan automatically adjusts the fan RPM based on PSU load. If the power stays below 150Watts, the fan will go into idle mode and not spin while automatically adjusting over 150W.

There are also heatsinks used within the PSU compartment which feature 200% larger volume and more fins for optimized airflow. Gigabyte claims that they have increased the heat dissipation by 10 percent on their new UDGM series PSUs. The 10% figure is obtained by measuring different PSU components such as the PFC MOS temp which sees a temperature reduction of 6%, 13% decrease on the LLC MOS, and 14.5% on the SR MOS.

As for the UD1000GM PG5, it comes with the latest PCIe Gen 5.0 (16-pin) connector which outputs 600W native power. This will allow the GPU to be fully compatible with next-gen PCIe Gen 5.0 compliant graphics cards.

Gigabyte UD1000GM PG5 & UD750GM 80+ Gold PSU’s  Unboxing & Close Up

The units we received come in a standard black and orange colored package with a picture of the PSU on the front. The front also lists down several features such as its fully modular design, main Japanese capacitors, and the smart fan technology infused within the 120mm HYB fan.

The backside also offers a list of features which we have detailed above and we will get to more details in our tear-down in a bit.

Within the package, the PSU unit is held between foam packaging to protect it during shipping while the cables are supplied in their own separate plastic pouch. There are also four screws supplied with the PSU for installation within your casing along with a power cord.

The PSU itself is packaged within a top and bottom foam cover.

The PSU also has a lot of weight to it which gives you a hint of the quality components featured within it.

On the back, you can see the power plug, the power switch, and a large mesh panel that acts as an exhaust vent.

Now depending on how you use the PSU, the bottom panel reads the specifications and power ratings.

The sides of the PSU have a nice Gigabyte Ultra-durable and Gold rating logo.

Coming to the connectors, there are two 8-Pin CPU connectors, an ATX 24-pin (14+10 pin) ATX connector, and three 5-pin connectors for peripherals. The UD1000GM PG5 comes with a single CPU/PCIe 8-pin connector that outputs two 8-pin connectors and a 16-pin Gen 5 connector while the UD750GM comes with a triple 8-pin PCIe connector configuration.

The cables within the packaging pouch include the ATX 20+4 pin, two  4+4 pin CPU connectors, 4 PCIe 6+2 connectors, 8 SATA connectors, 3 MOLEX connectors, and a single floppy connector. The UD1000GM comes with a single PCIe Gen 5 cable.

Gigabyte UD1000GM PG5 & UD750GM 80+ Gold PSU’s Final Impressions

Coming to the final impressions, first, we have to state the pricing. The Gigabyte UD1000GM PG5 is currently listed over at Newegg for $159.99 US while the UD750GM is listed for $129.99 US. These are really good prices, especially when you consider the 1000W unit which comes with PCIe Gen 5.0 compliancy. Now the PSU isn’t a true ATX 3.0 design but it still is ready for next-gen graphics cards with up to 600W of power requirements. The UD750GM is a decent price but it is competing in a heavily saturated market where several units are currently priced closer to $100 US.

In terms of features that Gigabyte is offering, both UD GM series offers a complete list of protection against voltage and power fluctuations. The main question on everyone’s mind would be will these PSUs blow up in a similar fashion as Gigabyte’s previous P GM attempt? Well, the answer is that the issue is mostly rectified in the newer revision and Gigabyte learned a lot from its previous attempt and won’t want to repeat that. I will say that through my time testing both units, even under a full load of an RTX 3090 Ti overclocked graphics card and an overclocked Core i9-12900K CPU, I didn’t face any power issues or random restarts, let alone the PSU blowing up. So overall, Gigabyte has a decent offering that’s very good in terms of price when it comes to 1000W Gen 5 designs. I will be testing them more in the months ahead to see how they respond to different kinds of hardware & putting more strain on them through some overclocking tests but for now, I find these units to be a great fit for your new PC builds.
