Dimension Scores
It boasts 80 PLUS Gold (90%+) and Cybenetics Platinum efficiency, supporting 750W continuous output and 220% power excursion for transient loads.
Equipped with a 135mm FDB fan and Cybenetics LAMBDA A acoustic certification, it's designed for quiet operation.
It uses 100% Japanese capacitors and comes with a 10-year warranty, indicating a focus on long-term durability and reliability.
As a fully modular power supply with individually braided cables, it offers superior flexibility for routing and airflow compared to non-modular or semi-modular units.
Best For
- PC builders using high-end GPUs that require a native 12V-2x6 connector.
- Gamers seeking a power supply compliant with the latest ATX 3.1 and PCIe 5.1 standards.
- Users prioritizing energy efficiency with 80 PLUS Gold and Cybenetics Platinum ratings.
- Enthusiasts who value a clean build with fully modular, individually braided cables.
Not Recommended For
- Budget-conscious builders who don't need ATX 3.1 or PCIe 5.1 compliance.
- Users in regions where the NEMA 5-15P power cord is incompatible without an adapter or replacement cable.
- Systems with low power demands, as 750W might be overkill.
Watch Out For
- One user experienced the PSU shutting off randomly, and reported difficulties with the support website.
- The power cord included is a C13 to NEMA 5-15P, which means users in countries like Ireland (using BS 1363) will need to source a compatible cable separately.
- While fully modular, the individual braided cables can be stiffer than ribbon cables, potentially making routing in compact cases more challenging.

What Buyers Say
While the ASRock Phantom Gaming PG-750G generally receives positive feedback for its modern features and quiet operation, one user reported a critical issue of random shutdowns and unresponsive support. Many users appreciate the fully modular design and the inclusion of the native 12V-2x6 cable, making it suitable for current high-performance builds. The 10-year warranty is a recurring point of confidence, but the regional power cord compatibility is a minor inconvenience for some.
“My PC kept shutting off randomly, and when I tried to get help, the support site was just broken. Not what I expected for a new PSU.”
Common Praise
- Easy installation with standard mounting holes.
- Provides stable power delivery, especially for high-performance GPUs.
- Operates quietly at moderate usage levels.
- Includes quality cables with built-in safety features for GPUs.
- Modular design significantly helps with cable management, reducing clutter.
- The 10-year warranty enhances the perceived value and reliability.
Common Complaints
- One user experienced random PSU shutdowns and reported issues with the support website.
- The included power cord (C13 to NEMA 5-15P) is not universally compatible, requiring users in some regions to buy a different one.
- The individual braided cables, while aesthetically pleasing, can be less flexible than ribbon cables, making tight cable routing difficult.
Ownership Tips
- The dual-color 12V-2x6 connector is actually pretty helpful for making sure it's fully seated, especially with how much power those new GPUs draw.
- The individually braided cables look slick, but they're a bit stiff, so plan your cable runs carefully in smaller cases.
- The fan is genuinely quiet under normal gaming loads; you'll hear your GPU fans before this PSU.
- The 5V BOOST switch is there, but honestly, I haven't found a reason to use it or even notice a difference with my peripherals.
Frequently Asked Questions
Is this power supply compatible with older motherboards?
Yes, this power supply is backward compatible with older ATX standards, but it's specifically designed to meet the newer ATX 3.1 and PCIe 5.1 standards for modern components.
Does this PSU come with all the necessary cables?
Yes, it's fully modular and includes all standard cables, including a native 12V-2x6 cable for PCIe 5.1 GPUs, with an individual braided pattern.
How quiet is this power supply?
It features a 135mm Fluid Dynamic Bearing fan with iCOOL Intelligent Fan Control and has a Cybenetics LAMBDA A acoustic certification, indicating quiet operation.
What does the 10-year warranty cover?
The 10-year warranty typically covers defects in materials and workmanship, providing long-term assurance for the product's reliability.
What is the purpose of the NTC sensor on the 12V-2x6 cable?

Buying Guide
When you're looking at a power supply, you're basically buying the heart of your PC. It needs to deliver consistent, clean power to all your expensive components. You want enough wattage for your current setup and a little headroom for future upgrades. Efficiency ratings tell you how much power is wasted as heat, and modern standards like ATX 3.1 and PCIe 5.1 are crucial if you're building with the latest graphics cards, as they handle power spikes much better.
Wattage (750W)
This is the total power your PSU can deliver. Think of it like the horsepower of a car; 750W is enough for most mid-to-high-end gaming PCs, especially with a single powerful GPU.
80 PLUS Gold & Cybenetics Platinum
These are efficiency ratings. Gold means at least 87% efficient at 100% load, and Platinum is even higher. Higher efficiency means less wasted electricity (lower power bills) and less heat generated by the PSU itself.
ATX 3.1 & PCIe 5.1
These are the latest industry standards. ATX 3.1 ensures the PSU can handle rapid power draw changes from modern CPUs, and PCIe 5.1 means it has the new 12V-2x6 connector and can deliver up to 600W to a single graphics card, preventing issues with high-power GPUs.
Fully Modular
This means you only plug in the cables you need. It's like having custom-length cables for your PC, making cable management much cleaner, improving airflow, and making your build look tidier.
Alternatives
If this wattage isn't enough, look for PSUs with 850W or 1000W, maintaining ATX 3.1 and PCIe 5.1 compliance. If you're on a tighter budget and don't need the absolute latest standards, an 80 PLUS Bronze or Gold ATX 2.x PSU might suffice, but ensure it has the necessary connectors for your GPU.
