Power supplies, are not usually the most exciting thing to look for when you are building a new PC. The basics that you usually look at are the rating, can it run my CPU and GPU, the form factor, will it fit my case, and the price. That is what most people consider when they are PSU shopping.
Gigabyte, the name is synonymous with durability and reliability, with traits like that it makes only sense that they bring us the ULTRA DURABLE (UD) range of power supplies. We are looking at the 750W Gold-rated variant. Let’s see what they are all about.
Design
Instead of going for an extreme and eye-catching design, the Gigabyte UD750GM power supply prefers to go for a more understated look and focus on the internals rather than the exterior. Not that the exterior is ugly by any means. The Gigabyte UD750GM power supply sizes up at 150mm x 140mm x 86mm making sure it will fit basically any case you could want to put it in.
On the outside there is nothing significant to note, it is a black power supply with white and grey accents in the way of writing and labels. A normal installation will see the 120mm fan that features smart hydraulic bearings, to be downwards facing allowing it to suck cold air over the components. Thanks to its fully modular design every single cable can be removed giving it a very clean look straight out of the box.
Key Features
The Gigabyte UD750GM power supply does not bare the UD letters for no reason. UD stands for ULTRA DURABLE and the reason for this is because Gigabyte has taken every possible precaution and step to ensure that their UD range of PSUs is fitted with the best components possible. Some of the main features are as follows:
- Main Japenese Capacitors
- Enhanced thermal Solutions
- 120mm smart Hydraulic bearing fan
- OVP/OPP/SCP/UVP/OCP/OTP protection
- 80 Plus Gold certified
- Fully Modular design
- Powerful Single 12V+ rail
- Compact size
- 5 Year warranty
Gigabyte has done the research and they have found that using Japanese capacitors as the main capacitors in their Power supplies can significantly extend the lifespan of the components. In fact, in ideal conditions, the capacitors can last up to 4x longer than conventional capacitors.
Thanks to the 120mm Smart Hydraulic bearing fan as well as reworked thermal solutions the Gigabyte UD750GM power supply is able to work harder for longer without damaging its components. Heat dissipation performance has increased by more than 21% which can mean the difference between failure and an extended lifespan. The other advantage of the above-mentioned features is that the Gigabyte UD750GM power supply is able to keep the fan silent during low load (less than 20% load).
The Gigabyte UD750GM power supply is also fitted with plenty of protection to ensure that your PC is protected from unwanted power spikes. The Gigabyte UD750GM power supply is fitted with OCP (overcurrent protection), OTP(over-temperature protection), OVP (over Voltage Protection), OPP (Over Power Protection), UVP (under-voltage protection), SCP (short circuit protection).
For those who have never been sure what the 80 plus gold certified means, The 80 Plus Gold rating means that the PSU is rated for at least 87% efficiency at 20% load, 90% at 50% load, and 87% at 100% load.
Gigabyte UD750GM is also a fully modular power supply, this means that you only have to install the cables you need. The cables are all packed into a flat side-by-side layout. The Gigabyte UD750GM has plenty of cable options:
- 1 x MB (20+4 Pins)
- 2 x CPU (4+4 pins)
- 4 x PCI-E (6 + 2 Pins)
- 8 x SATA
- 3 x Peripheral
- 1 x Floppy
The Gigabyte UD750GM also features a single 12V+ Rail. This means that the 12V line is not simply tapped from elsewhere, or the 5V rails are not tapped from a 12V rail. This gives the best power delivery and stability while also allowing for more specific cable usage.

Verdict
While PSUs are typical an overlooked component, they do play a pivotal role in the longevity of your build. Not only that they could mean the difference between a stable system and not. Thanks to Gigabyte deciding to NOT cut corners and use good quality parts, the ULTRA DURABLE range blends quality with affordability without skimping out on either of the two.
We popped the Gigabyte UD750GM into our rig, Gigabyte Z690 Gaming X, fitted with a 12700k i7, cooled by the beauty that is the Aorus Waterforce 360, running 32Gb of RAM, and an RTX2080. Pushing these components to their limits does come close to what the Gigabyte UD750GM can do but it did not falter once!
Using a Corsair 4000D case did mean that cable routing needed to be exact, and the flat black cables used in the Gigabyte UD750GM worked effortlessly and felt like they had a bit of extra length compared to our usual PSU that we use. That is a massive plus for those who use larger cases.
We cannot fault the Gigabyte UD750GM in any way, shape, or form. if the 750W variant is a bit light for your liking there are 850W and 1000W variants as well.
Nothing in this world is perfect however, the Gigabyte UD750GM is aimed at mid-to-high tier users, and with that in mind, there could have been a few additions to really make it great. Sleeved cables are something that really does give a build that extra wow factor.
Another nice addition would be something that many other cheaper brands do, which is to provide you with a bag for both the PSU and cables, which makes it great for storing and keeping everything together. This is not something major but little things like that do make the difference
