- Some users have reported the 120mm fan can be 'a bit loud'.
- One user reported a unit failing after just over a month.
Dimension Scores
The 80 PLUS Gold certification means it achieves up to 90% energy efficiency, and its 750W capacity with ATX 3.1 and PCIe 5.1 compliance is current.
While advertised with a 'low-noise fan,' one user reported it being 'a bit loud,' indicating it might not be consistently quiet for all users.
It includes a full suite of protections (OCP, SCP, OVP, UVP, OTP, OPP) and uses all Taiwanese capacitors, but one user reported a unit failing quickly.
As a non-modular power supply, all cables are permanently attached, making cable management more challenging than with modular units.
Best For
- Budget-conscious PC builders needing ATX 3.1 and PCIe 5.1 compatibility.
- Systems with mid-range to high-end GPUs requiring a native 12V-2x6 connector.
- Builds where cable aesthetics are less critical due to the non-modular design.
Not Recommended For
- Users prioritizing a clean, minimalist build with fully modular cabling.
- Anyone needing a longer warranty period for peace of mind.
- Silence-focused builds where fan noise is a primary concern.
Watch Out For
- The non-modular design means you'll have extra cables to hide, even if unused, which can be a pain for smaller cases.
- A 3-year warranty is on the shorter side; some competitors offer 5 or even 10 years, so factor in potential replacement costs sooner.
- One user experienced a unit failing after just over a month, indicating potential reliability concerns for some units.
- Despite the 'low-noise fan' claim, at least one user found it 'a bit loud'.

What Buyers Say
This ASRock PRO 750G PSU pops up frequently in budget build discussions because of its price, but you're making some compromises. The non-modular cables are the biggest headache, forcing you to stash unused wires, which is a pain in smaller cases. While it's got the latest ATX 3.1 and PCIe 5.1 specs with a native 12V-2x6 connector, which is awesome for modern GPUs, that 3-year warranty feels short when other brands offer double or triple that. Plus, even though it claims a 'low-noise fan,' some folks have found it to be 'a bit loud'.
“Look, for the price, it's hard to complain about the non-modular cables, but seriously, a 3-year warranty? I'm already nervous about it dying on me after a year, especially with that one review saying it crapped out so fast. I just needed something cheap that wouldn't melt my new GPU.”
Common Praise
- Supports ATX 3.1 and PCIe 5.1 standards for current hardware.
- Native 12V-2x6 connector handles up to 450W for modern GPUs.
- 80 PLUS Gold certification provides good energy efficiency.
- The price point is very attractive for its wattage and features.
Common Complaints
- Non-modular design creates cable clutter.
- The 3-year warranty is considered short by many users.
- Some units are reported to be noisy despite the 'low-noise' claim.
- One user reported a unit failing after a month.
Ownership Tips
- The flat cables are easier to bend and route than traditional sleeved cables, which helps a bit with the non-modular mess.
- The dual-color design on the 12V-2x6 connector is actually useful for confirming it's seated correctly.
- You'll definitely need zip ties or Velcro straps to manage the unused cables effectively in your case.
- The fan noise isn't constant, but it can ramp up under load and become noticeable.

Yes, it is ATX 3.1 and PCIe 5.1 compliant and features a native 12V-2x6 connector that can deliver up to 450W to modern high-performance graphics cards.
Is the fan quiet?
ASRock advertises a 'low-noise 120mm fan,' but at least one user reported it being 'a bit loud'.

The dimensions are 140mm (L) x 150mm (W) x 86mm (H).
Buying Guide
When you're looking at a power supply, you're basically buying the heart of your PC. It needs to deliver stable power to all your components without frying them. You need enough wattage for your CPU and GPU, and modern standards like ATX 3.1 and PCIe 5.1 are crucial if you're running a newer graphics card. Don't cheap out too much, because a bad PSU can take other components with it.
Wattage (750W)
This is the total power your PSU can supply. If your components (especially your CPU and GPU) demand more than 750W, your system will be unstable or won't even turn on. Think of it like the engine size in a car – you need enough horsepower for what you're trying to do.
80 PLUS Gold Certified
This certification indicates how efficiently the PSU converts AC power from your wall outlet into DC power for your PC. Gold means it's at least 87% efficient at 20% load, 90% at 50% load, and 87% at 100% load. Higher efficiency means less wasted electricity as heat, saving you a little on your power bill and keeping your case cooler.
ATX 3.1 & PCIe 5.1 Ready
These are the latest power delivery standards. ATX 3.1 ensures better power stability and transient response, especially for sudden power spikes from modern GPUs. PCIe 5.1 means it has the proper native connector (like the 12V-2x6) for newer graphics cards, so you don't have to use clunky adapters that can be a fire hazard.
Non-Modular
This refers to the cables. Non-modular means all cables are permanently attached to the PSU. This is cheaper to manufacture but leaves you with a bundle of unused cables to hide in your case, making cable management a chore. Fully modular PSUs let you attach only the cables you need, resulting in a much cleaner build.
Alternatives
If this PSU doesn't fit, look for fully modular 750W-850W 80 Plus Gold or Platinum PSUs with a 5-10 year warranty if you want easier cable management and longer-term peace of mind.
