Best For
- Gaming PC builds requiring ATX 3.0 and PCIe Gen 5.0 power delivery for modern GPUs.
- Systems where quiet operation during light loads is a priority due to 0dB Technology and Lambda A++ certification.
- Users building an ASUS ROG-themed PC who want integrated Aura Sync RGB lighting.
- Mid-range gaming setups with a single high-end graphics card.
Not Recommended For
- Budget-focused PC builds where the premium for RGB and extreme quietness is not justified.
- High-end systems with multiple power-hungry GPUs that might exceed 750W requirements.
- Users who are indifferent to RGB lighting and prefer a more understated aesthetic.
Watch Out For
- Coil whine has been reported by users, particularly when the system is at idle, which can be distracting despite the PSU's quiet certifications.
- The Aura Sync RGB lighting may not retain its last setting when the system is powered off, defaulting to a rainbow effect if the connector cable is not used or if there are software glitches.
- Some users have experienced issues with Aura Sync not controlling the PSU's RGB, requiring troubleshooting with Armoury Crate software or specific motherboard compatibility.
- A Reddit user reported their ROG Strix 750W Gold Power Supply 'went BANG' after some time, indicating a rare but severe failure.

What Buyers Say
The biggest takeaway from user feedback is the recurring issue of coil whine, which some users experience at idle, directly contradicting the PSU's quiet certifications. Despite this, many users praise its robust build quality and the inclusion of ATX 3.0 and PCIe Gen 5.0 support, making it future-ready for new GPUs. The Aura Sync RGB, while a selling point, can be finicky, with reports of it not remembering settings or requiring specific ASUS motherboard/GPU combinations for full functionality. The 0dB fan mode is generally appreciated for silent operation during low loads, but some older ROG Strix models have had fan noise complaints.
“Man, this PSU is super quiet when it's supposed to be, but then it just starts whining at idle and it drives me nuts, especially after paying extra for the 'Aura Edition' and the RGB doesn't even always work right.”
Common Praise
- The 0dB fan mode keeps the system completely silent during web browsing or light tasks.
- The ATX 3.0 and PCIe Gen 5.0 compatibility with the included 16-pin cable is appreciated for modern GPU support.
- The aluminum case and ROG heatsinks contribute to lower operating temperatures.
- The 10-year warranty provides significant peace of mind for long-term use.
- The fully modular cables make for a clean and organized build.
Common Complaints
- Noticeable coil whine, especially when the PC is idle, which is frustrating for a 'silent' PSU.
- Aura Sync RGB lighting sometimes defaults to rainbow or doesn't sync properly with other components.
- The RGB settings may not persist after a shutdown, requiring re-synchronization.
- Some users find the price too high compared to other 750W 80+ Gold PSUs without the RGB features.
Ownership Tips
- The coil whine is often most apparent when the system is at idle, not under load.
- Getting the Aura Sync RGB to consistently work and remember settings can require troubleshooting with Armoury Crate.
- The 0dB fan mode works as advertised, but when the fan does spin up, some users report a slight grinding or whining noise.
- The included cables are braided and of good quality, but some users might find the Molex connector spacing a bit tight.
Frequently Asked Questions
What does 'ATX 3.0' mean for this power supply?
ATX 3.0 is a new power supply standard that ensures better power delivery and transient response for modern, high-power components, especially graphics cards. It's designed to handle power spikes more effectively.
Is this power supply truly silent?
It features 0dB Technology, meaning the fan completely stops when the PSU load is 60% or below, making it silent during light use. It also has a Cybenetics Lambda A++ certification, indicating it averages less than 15 dB of noise.
Does it come with the new 12VHPWR cable for RTX 40-series GPUs?
Yes, it is PCIe Gen 5.0 ready and includes a 16-pin PCIe cable capable of delivering up to 600W, which is compatible with current generation graphics cards.
How does the Aura Sync RGB lighting work?
The PSU has addressable RGB lighting built-in that can integrate with the Aura Sync ecosystem. For full control and synchronization, you'll need a compatible ASUS or ROG motherboard.
What is the warranty period for this power supply?
ASUS provides a 10-year warranty for this power supply, covering potential defects and ensuring long-term peace of mind.
Buying Guide
When you're picking a power supply, you're basically choosing the heart of your PC. It needs to deliver enough juice to all your components reliably, especially your graphics card and CPU. Don't just look at the wattage; efficiency, noise, and future-proofing matter a lot. A higher efficiency rating means less wasted energy and less heat, which is always a win. Also, consider if you're going to upgrade your GPU soon, as newer cards have different power requirements.
Wattage (750W)
This is the maximum power your PSU can supply. For most mid-range gaming PCs with one high-end GPU, 750W is usually enough, but very powerful CPUs or multiple GPUs will need more. Think of it like the engine size in a car – you need enough horsepower for what you're trying to do.
80+ Gold Certified
This certification indicates the power supply's efficiency. 'Gold' means it's at least 87% efficient at 100% load, 90% at 50% load, and 87% at 20% load. Higher efficiency means less electricity wasted as heat, saving you a tiny bit on your power bill and keeping your PC cooler. It's like getting better gas mileage.
ATX 3.0 & PCIe Gen 5.0 Ready
These are the latest standards for power supplies, crucial for newer graphics cards. ATX 3.0 ensures the PSU can handle sudden power spikes from modern GPUs, preventing system crashes. PCIe Gen 5.0 readiness means it has the dedicated 16-pin cable (12VHPWR) needed for cards like NVIDIA's RTX 40-series, which can draw up to 600W through a single cable. It's like having the right adapter for a new, powerful appliance.
Fully Modular
This means all cables detach from the power supply. You only plug in the cables you need, which makes building your PC much cleaner and improves airflow inside your case. It's like having custom-length cables instead of a tangled mess.
Alternatives
If this PSU doesn't fit, look for a higher wattage (850W or 1000W) ATX 3.0 80+ Gold or Platinum certified unit if you need more power, or a non-RGB 80+ Gold unit if aesthetics aren't a priority and you want to save some cash.
