Gigabyte is a relatively new name in the PSU (Power Supply Unit) segment, however it has deep roots in the market with several offerings dating back to the early 2010s. The previous lineup was a mix of both high-end and generic offerings, but only recently has the brand has decided to streamline its offerings into various segments which include AORUS, UD and the more standard “P / G” offerings. While the AORUS offerings are the most premium designs, the UD line comes with some of the most affordable offerings. The UD brand stands for “Ultra Durable,” which has been Gigabyte’s design philosophy for generations. Today we’ll take a look at not one but two of Gigabyte’s latest UD series PSUs, the UD1000GM and UD750GM.

Gigabyte UD1000GM PG5 and UD750GM 80+ Gold power supply specifications

Coming straight to the specs, the Gigabyte UD1000GM PG5 is rated at 1000W while the UD750GM is rated at 750W. Top-notch, both of these PSUs feature similar specs, with an ultra-tough design consisting of Japanese main capacitors, an advanced thermal heatsink solution, 120mm intelligent hydraulic bearing fan (HYB) and a range of protection including OVP (over voltage protection) / OPP (over voltage protection) / SCP (short circuit protection) / UVP (undervoltage protection) / OCP (overcurrent protection) / OTP (overtemperature protection).

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 guarantees 90% efficiency at 50% load. The output current for the 1000W drive is rated at 83.3A (+ 12V) for a maximum combined power of 999.6W while the 750 unit is rated at 61A (+ 12V) for a 732W maximum combined power. Both drives are also compatible with Intel ATX 12V v2.31.

So, complementing the features we just stated above, Gigabyte UD power supplies offer:

  • Ultra resistant
    • Main Japanese capacitors
    • Enhanced thermal solution
    • 120mm Intelligent Hydraulic Bearing Fan (HYB)
    • OVP / OPP / SCP / UVP / OCP / OTP protection
  • 80 PLUS Gold certified
  • Fully modular design
  • Powerful single track + 12V
  • Compact design

As for the PSU design, they both have an ATX form factor and measure 150 x 140 x 86mm. Gigabyte calls it a compact design compared to standard power supply offerings that allow for easier installation in almost any PC chassis without worrying about space constraints. Moving on to cooling, the enclosure features a single 120mm Intelligent Hydraulic Bearing (HYB) fan, which offers 1.4 times longer life than standard sleeve bearing fans. As for the acoustics, the hydraulic fan automatically adjusts the fan speed according to the load of the power supply. If the power stays below 150W, the fan will enter idle mode and will not spin while automatically adjusting beyond 150W.

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

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

Gigabyte UD1000GM PG5 and UD750GM 80+ Gold PSU Unboxing and Close Up

The units we received come in a standard black and orange color package with a power supply image on the front. The front also lists several features such as its fully modular design, major Japanese capacitors, and intelligent fan technology infused into the 120mm HYB fan.

The back also offers a list of features that we detailed above and we’ll get to more details in our teardown shortly.

Inside the box, the PSU is held between foam packaging to protect it during shipping while the cables are supplied in their own separate plastic case. There are also four screws supplied with the power supply for installation inside the enclosure along with a power cord.

The power supply itself is packaged inside a top and bottom foam cover.

The power supply also has a lot of weight, which gives you an idea of ​​the quality components present within it.

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

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

The sides of the power supply have a nice Gigabyte Ultra-tough and Gold logo.

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

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

Final impressions of the Gigabyte UD1000GM PG5 and UD750GM 80+ Gold power supply

Coming to the final impressions, first, we need to indicate the price. The Gigabyte UD1000GM PG5 is currently listed on 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 drive that comes with PCIe Gen 5.0 compliance. Now the power supply is not a true ATX 3.0 design but is still ready for next generation graphics cards with power requirements up to 600 W. The UD750GM is priced decent but competes in a heavily saturated market where several units are currently priced closer to $ 100 US.

In terms of the features offered by Gigabyte, both UD GM series offer a comprehensive list of protection against voltage and power fluctuations. The main question on everyone’s mind would be that these power supplies will explode similar to Gigabyte’s previous P GM attempt? Well, the answer is that the problem is mostly rectified in the most recent revision and Gigabyte has learned a lot from its previous attempt and won’t want to repeat it. I will say that during my time testing both units, even under full load with an overclocked RTX 3090 Ti graphics card and an overclocked Core i9-12900K CPU, I encountered no power issues or random reboots, let alone the explosion of the CPU. ‘power supply on. So overall, Gigabyte has a decent offering that is very good in terms of price when it comes to 1000W Gen 5 designs. try it through some overclocking tests, but for now I find these drives perfect for your new PC builds.
