I’m writing this review after spending quality time with my ROG Thor 1200W Platinum II power supply, and I must say, I’m genuinely impressed. Right off the bat, one aspect that stands out is its incredibly smooth and linear power delivery. Being an avid gamer, I’ve got it hooked up to my graphics card that often operates at full throttle. What struck me was the unwavering consistency in the power supply, even under such demanding circumstances. It never misses a beat, ensuring my gaming sessions are uninterrupted and my equipment runs flawlessly. Aside from its reliable performance, this power supply comes with a few bells and whistles that I find very appealing. The OLED display, for one, is a neat feature. It adds a futuristic touch, providing useful information right at my fingertips. Moreover, the ROG Thor 1200W Platinum II is as stylish as it is functional. The sleeved cables and the Aura Sync compatibility give me the freedom to customize my setup’s aesthetics. And let’s not forget the 0dB mode - it’s so silent, you wouldn’t know it’s working hard to power up your rig. It’s also worth noting that the 10-year warranty brings an extra layer of reassurance, underscoring the quality and longevity of this power supply. All in all, the ROG Thor 1200W Platinum II power supply has not only met but exceeded my expectations. It’s a reliable powerhouse, delivering consistent performance while adding a touch of style to my rig. This is one investment I’m truly pleased with!

Wow - this is easily the best PSU I have ever owned. Top notch in every way and well engineered. It just looks great and having the live LED power draw showing on the side is really cool and useful. More high cables are include than you could ever need. I highly recommend this product.

The media could not be loaded. I recently upgraded to the **ASUS ROG Thor 1600W Titanium** for my high-end gaming/overclocking rig, and it’s been nothing short of impressive. This power supply is **an absolute beast** in terms of both specs and real-world performance. Here’s my detailed breakdown after a few weeks of use: - **Value & Target Audience:** This PSU isn’t cheap (around **$700**), but it’s clearly aimed at **enthusiasts, extreme overclockers, or gamers** running top-of-the-line gear. If you’re building an **overkill rig with multiple GPUs or an RTX 4090/5090-class card**, the Thor 1600W provides all the headroom you need. For a casual builder, it’s overkill; but for those who demand the best, the value is in the **peace of mind and performance** you get. It even comes with a new **PCIe 5.0 16-pin (12VHPWR) cable** for next-gen graphics – a nice future-proof bonus. Yes, the price is high, but considering the features and the 10-year warranty, I’d say it’s worth it for high-end builds. - **Build Quality & Design:** The build quality is outstanding – as soon as you unbox it, you can feel the heft and quality. It’s a **fully modular** design, so I only plugged in the cables I actually needed (no more unused cables cluttering the case). The included cables are premium **sleeved cables** which look fantastic and are easy to route (and ASUS even throws in a 20% CableMod discount for custom cables. Inside, ASUS has packed **ROG heatsinks** over key components (these heatsinks have **2X the volume of typical PSU heatsinks**, which leads to about *20% lower internal temperatures*. Even the switching transistors use fancy **GaN (Gallium Nitride) MOSFETs** instead of typical silicon – this allows the PSU to handle huge power with less energy loss. Overall, the unit has a sleek **ROG aesthetic** (black finish with subtle ROG cyber-text accents) and even a little **OLED display** on the side. The design is both **industrial and premium**, and it fits nicely in my full-tower case (note: it is a bit longer than standard PSUs, so check your case space if you have a mid-tower). - **Performance & Efficiency:** In terms of power delivery, this thing is rock solid. It’s **80+ Titanium rated**, which is the highest efficiency tier for PSUs – meaning it wastes very little power as heat (up to ~94% efficient at typical loads). They used high-end Japanese capacitors to achieve this level of efficiency and reliability. In practice, my system (with a power-hungry CPU and GPU) runs extremely stable even under full load. No random shutdowns or voltage drops – it’s clear the **digital power control** is working to keep the output steady. The PSU has a **digital controller that reacts instantly to load changes**, so when my GPU spikes power draw, the Thor handles it without breaking a sweat. I’ve also done some overclocking on my CPU/GPU, and the Thor 1600W delivers **clean, stable power** throughout. It’s honestly over-spec’d for my current needs, but that means the PSU is always in a comfortable range (which likely contributes to its longevity and stability). - **Noise & Cooling:** One of the big surprises is how **quiet** this PSU is, given its massive capacity. ASUS really focused on cooling – those oversized ROG heatsinks I mentioned help dissipate heat passively, and they make a noticeable difference. The unit stays cool to the touch. It has a **135mm “Axial-tech” PWM fan** that, according to ASUS, moves ~21% more air with lower RPM. In my experience, the fan rarely even spins up. There’s a **0dB mode** (fan stops completely) when load is under 50%, and since 50% of 1600W is **800W**, my system doesn’t trigger the fan at idle or low loads at all. Under gaming loads (~500-600W draw in my case), the fan sometimes *barely* comes on, but I can’t hear it over my case fans. This PSU actually earned a **Lambda A++ noise certification** (a very elite rating), which basically confirms how insanely quiet it is. Even when I stressed the system to pull ~1000W+, the fan ramped gently, still quieter than my GPU fans. For a 1600W PSU, the noise performance is superb. No coil whine issues so far either. - **Extra Features (OLED & RGB):** The **OLED power display** on the side is not just a gimmick – I’ve found it surprisingly useful and fun. It shows real-time wattage consumption of your system. During heavy gaming or benchmarking, I love glancing at it to see “wow, my system is drawing 750W right now.” It’s a great little **monitoring tool** when you have an open or windowed case, and it adds a bit of techy flair. The PSU also has **integrated RGB lighting** (the ROG logo and some accents), which supports **Aura Sync**. I synced it with the rest of my ASUS components so it matches my motherboard and GPU lighting – it’s a nice touch for a clean, unified look. If you’re not into RGB, you can disable or ignore it, but for RGB enthusiasts, it’s a plus. These extras (OLED, RGB) don’t improve performance, but they enhance the overall *cool factor* and customization of your build. It’s clear ASUS designed this not just as a power box but as a showcase piece for high-end rigs. - **Installation & Use:** Installing the ROG Thor 1600W was straightforward. Despite being larger than a typical PSU, the fully modular design meant I could wire up everything outside the case and then just slide the PSU in. **Ease of installation** was actually better than some smaller non-modular units I’ve dealt with, simply because you don’t have a fixed bundle of cables in the way. The cables provided are of ample length (I had no issue routing cables in a big tower case). One thing to note: this PSU is **heavy** – you’ll definitely want to screw it in securely, and support it while installing. Once in place, it’s rock solid. All connectors (24-pin, EPS, PCIe, etc.) are high quality and plugged into my components firmly. I also appreciated that **ASUS includes a 16-pin GPU cable** in the box for the latest video cards – no need for adapters or buying a cable separately. Using the PSU day-to-day is basically transparent: it powers on, runs quietly, and I haven’t had to think about it, which is exactly what you want from a PSU. The OLED defaults to showing wattage; I didn’t have to configure anything special (though you can turn off the display or change settings via Armoury Crate if you want). - **Drawbacks or Quirks:** It’s hard to find negatives, but I’ll list a couple of considerations. **First, the price** – it’s undeniably a premium product, and you pay for it. If you don’t need this much power or the extra features, there are much cheaper options out there. For me, the stability and features justified the cost, but it’s not an “average value” unit; it’s a **premium, no-compromise unit**. **Second, the size** – make sure your case can accommodate a PSU that’s about 20cm long. In a standard ATX case with a PSU shroud, you might have to remove any drive cages or plan your space. It fit fine in my case, but it is longer than a standard 750W unit, for example. **Third, the OLED placement** – depending on your mounting orientation, the OLED panel might face the wrong side or be hidden. In my setup (fan facing down, in a bottom PSU shroud), the OLED is actually visible through a cut-out, but not every case has that. If you mount the PSU fan-up, then the OLED would be upside down. *Minor nitpick:* the OLED’s usefulness is mostly when you’re actively looking into your case – you won’t see it if your case is closed/off to the side. Finally, one should consider that a 1600W PSU *at full tilt* will draw a lot of power from the wall (though that’s expected – and at least it’s efficient). For most of my use, it’s been in the sweet spot of efficiency. I really have no complaints in terms of performance or quality. No odd behaviors, no noises – it’s been **100% reliable** so far. **Overall:** The ROG Thor 1600W Titanium is an absolute unit of a PSU. 💪 It delivers **ultra-stable, efficient power** with practically **no noise**, and it’s packed with enthusiast features that make it a centerpiece of a build rather than an afterthought. It *is* expensive and overkill for many systems, but if you’re the target user (high-end enthusiast, or someone who just wants a “buy once, cry once” power supply), it’s hard to do better than this. The quality, performance, and extras put it in a league of its own. **9.5/10 from me!** I’m extremely satisfied with it – my rig feels ready for anything, and I have peace of mind that this PSU will handle upgrades and stress for years to come. Highly recommended for those who need **the best of the best** in a power supply. 👏🏼

Pros: Plenty of usable wattage for a gaming build. Currently powering an AMD 9800 X3D and FE 5090. Easy-to-read display showing current power draw Customizable RGB Nice and bright RGB with full spectrum color range REALLY QUIET even at full load. The GPU fans are louder than this PSU Cons -Not really a hit on the PSU, but syncing Armory Crate RGB isn't a bit of a chore. But once you get it right, it looks great -Depending on your case, you've got to be smart about cable management. Comes with a plethora of power cables, but they are long and will require some savvy tucking. I'm sure it's for full-size cases, and I use a test bench, so I had to invest in a lot of cable ties to keep it neat. You won't be disappointed. Lot's of headroom for upgrades.

OK let’s face it. You don’t know me. But I am a huge ASUS fan and I have been buying their products for years. However, I have only purchased motherboards, video cards, monitors, but I’ve never purchased a power supply of their brand. I did my research and I ended up getting this one because I needed 1000 W and I was looking for something add long-term and something that has had good reviews and most of all that had a really good rating. And this one delivered all that. Now I’ve been running this for a month now and I can tell you it’s very powerful and it runs cool and very quiet. All the bells and whistles are not a plus for me but it may be for you like the lights on the side and it’s cool mirror look, but mine will be hidden and not viable for the naked eye. So I needed something to add a good rating and a good warranty. My last power supply lasted nine years so, I chose this and I am so glad I did. If you look at all the specs, everything matches up and then some. They have had years of pros and cons to all their products in their brand, but I’m here to tell you this one delivers. But like anything, do your research, pay attention to what you need in your environment, but I honestly feel this would be a good fit for just about anybody that needs this much power.
