AI Verdict
This is a premium A-tier 750W power supply built on a modified Seasonic platform, perfect for mid-range gaming rigs where massive heatsinks and a 10-year warranty justify the Asus tax.
The A-tier reliability and oversized heatsinks provide excellent thermal headroom, but the stiff cables and 0dB mode fan noise frustrate many builders. You pay an extra $30 purely for the ROG heatsinks and aesthetic magnets compared to identical platforms.
If you want softer cables and a quieter fluid-dynamic fan for less money, look at the Corsair RM750x.

Chance this product isn't for you
Pros
- Built on the highly regarded Seasonic Focus Plus Gold platform with 100% Japanese capacitors
- Internal ROG heatsinks have twice the volume of standard designs, keeping temperatures low
- Scores an A-Tier rating on the Cultists Network PSU Tier List
- Includes a 10-year warranty covering core product operation
- Fully modular design includes two 4+4 pin CPU cables and four 6+2 pin PCIe cables for high-draw components
Cons
- The 0dB fan mode causes a loud spin-up noise when crossing the 40% load threshold
- In-line capacitors on the 24-pin and PCIe cables make the ends bulky and difficult to bend in tight cases
- Double ball-bearing fan produces a slightly higher baseline hum than fluid dynamic bearing alternatives
- Costs $20 to $35 more than competing 750W Gold units from Corsair and Seasonic
Dimension Scores
Easily handles 750W continuous loads with top-tier Japanese capacitors and an 80 Plus Gold certification.
Massive heatsinks keep it cool, but the double ball-bearing fan and 0dB spin-up noise drag down the acoustic performance.
Features a rock-solid Seasonic-built platform with oversized internal heatsinks and a 10-year warranty.
The fully modular design is great, but the thick in-line capacitors make the main cables stiff and hard to bend.
Best For
- Mid-range gaming builds running RTX 4070 or RX 7800 XT GPUs
- Systems housed in cases with poor airflow where the double ball-bearing fan's high-temperature tolerance is necessary
- Builders who want to customize their PSU shroud with the included magnetic ROG logos and stickers
Not Recommended For
- Ultra-compact ITX builds where stiff, capacitor-bulged cables won't fit behind the motherboard tray
- Absolute silence purists who will notice the dual ball-bearing fan motor noise
Watch Out For
- The 0dB fan mode creates a jarring revving sound every time the system hits 40% load — you need to press the physical button on the back to disable it for consistent acoustics.
- The included PCIe and 24-pin cables have thick embedded capacitors near the connectors, making them incredibly stiff and hard to route through standard case grommets.
- You pay a premium for the ROG branding and magnetic stickers, while the underlying Seasonic Focus GX-750 costs significantly less for identical power delivery.

What Buyers Say
The most recurring theme in user forums is the love-hate relationship with the 0dB fan mode. Buyers constantly report a strange, loud revving noise when the fan kicks on at 40% load, prompting most to permanently disable the feature via the rear button. Beyond the fan quirk, builders praise the rock-solid stability and the oversized internal heatsinks that keep the unit icy under heavy gaming loads. Cable management draws frequent frustration because the sleeved cables contain bulky in-line capacitors that resist bending near the motherboard.
“Great power supply but the 0db mode is a joke, it makes this awful grinding spin up noise every time I launch a game so I just leave the fan on 24/7 now.”
Common Praise
- Rock-solid power delivery with zero system crashes under heavy gaming loads
- Massive internal heatsinks keep the unit completely cool to the touch
- 10-year warranty provides massive peace of mind
- Magnetic ROG logos are a fun touch for cases with PSU cutouts
Common Complaints
- 0dB mode causes an annoying revving noise when the fan turns on
- In-line capacitors make the 24-pin and PCIe cables extremely stiff
- Double ball-bearing fan has a slight mechanical hum compared to FDB fans
- Overpriced compared to the Seasonic unit it is based on
Ownership Tips
- Disabling the 0dB button on the back permanently fixes the fan spin-up noise without affecting temperatures.
- The stiff cables require aggressive pre-bending before you try to plug them into your motherboard or GPU.
- The dual ball-bearing fan motor noise becomes slightly more noticeable after a few months of use, though it never gets loud.
Frequently Asked Questions
Why does the fan make a loud noise when I start a game?
That is the 0dB mode kicking off. When the PSU hits 40% load, the fan spins up aggressively. Press the 0dB button on the back of the unit to keep the fan spinning constantly and eliminate this revving sound.
Are the cables sleeved or flat?
It includes a mix. The main 24-pin, CPU, and PCIe cables are sleeved with thick black mesh, while the SATA and Molex cables are flat ribbon style.
Can I use this with an RTX 4080 or 4090?
No. This is a 750W unit with standard 6+2 pin PCIe cables. High-end 40-series cards require an ATX 3.0 power supply with a native 12VHPWR connector and at least 850W of headroom.
Who actually manufactures this power supply?
Seasonic builds the internal platform based on their Focus Plus Gold architecture. Asus adds their own custom PCB layout, oversized ROG heatsinks, and an Everflow Axial-tech fan.
Do I have to use the ROG stickers and magnets?
No. The power supply is plain black out of the box. The magnetic logos and stickers are completely optional.
Buying Guide
When buying a power supply, you pay for the internal components, the fan quality, and the cables. This Asus unit uses a top-tier internal platform built by Seasonic, meaning it safely delivers power to your expensive graphics card. You pay a premium for the ROG branding and oversized heatsinks. If you have a tight case, the stiff cables included in this box will fight you during installation.
80 Plus Gold
This is a measure of energy efficiency. A Gold rating means it wastes less power as heat compared to Bronze units, saving you a few bucks on your electric bill over its 10-year lifespan.
Fully Modular
You only plug in the cables you actually need for your specific build. It keeps the inside of your PC looking clean and improves airflow by eliminating a rat's nest of unused wires.
Double Ball-Bearing Fan
This fan type lasts significantly longer in hot environments than standard sleeve bearings, making it ideal if your PC sits in a warm room or a restrictive case.
Alternatives
If you want softer, capacitor-free cables and a quieter fluid-dynamic fan, search for an 80 Plus Gold 750W unit from Corsair or Seasonic.
