AI Verdict
This 1650W ATX3.1 PCIe5.1 Titanium PSU is for extreme builds running multiple power-hungry GPUs, offering dual 12V-2x6 cables and a 10-year warranty.
This 1650W Titanium-rated PSU with ATX 3.1 and PCIe 5.1 support is a strong contender for very specific, high-power builds. Its dual 12V-2x6 cables are perfect for multiple next-gen GPUs, but the reported early failures are a concern for a product in this price band. It's not a general-purpose PSU.
If you don't need 1650W or dual 12V-2x6 connectors, look for a lower wattage ATX 3.1 PSU with a Cybenetics Platinum or Gold rating to save money and potentially reduce the risk of early failure.

Dimension Scores
Achieves 80 PLUS Titanium and Cybenetics Titanium/Lambda A+ certifications, indicating top-tier efficiency, especially at 230V.
Features a 135mm FDB fan and iCOOL Intelligent Fan Control, allowing for silent operation at low to medium loads.
Uses 100% Japanese capacitors and has a 10-year warranty, but multiple user reports of early capacitor failure are concerning.
Fully modular design with individual braided pattern cables and two native dual-color 12V-2x6 cables for clean routing and modern GPU support.
Best For
- Systems with dual RTX 4090s or similar power-intensive GPU configurations
- Enthusiast PC builds requiring ATX 3.1 and PCIe 5.1 compliance for future-proofing
- Workstations or gaming rigs with peak power draw exceeding 1400 watts
Not Recommended For
- Budget-conscious builds where 1650W is excessive and less efficient units are sufficient
- Compact ITX cases due to its 180mm length
- Users prioritizing absolute silence at all loads, as the fan runs continuously in iCOOL Off mode
Watch Out For
- Multiple reports of capacitor failure causing a loud bang and system shutdown, even under idle conditions
- The product description states it's "Not compatible with all built-in computers or systems," which is vague and could lead to compatibility issues.
- Absence of fan failure protection, meaning you won't get an alert if the fan stops spinning

What Buyers Say
This ASRock Taichi 1650W PSU is a beast for power delivery, especially with its dual 12V-2x6 cables for hungry GPUs. However, there are recurring complaints about early capacitor failures, with users reporting loud pops and the unit dying, sometimes under idle conditions. While many users are running dual RTX 4090s without issue, the failure reports are a significant red flag for a premium product. The 10-year warranty is reassuring, but dealing with an RMA for a brand new PSU is a hassle.
“Man, this thing died on me after like 3 days, just a loud pop and black bits everywhere, and I wasn't even gaming, just downloading stuff. What a joke for a 'flagship' PSU.”
Common Praise
- Provides two native 12V-2x6 cables, ideal for dual high-end GPUs
- Handles significant power draw, with users running systems pulling ~1400 watts from the wall
- Fully modular cabling simplifies system building and cable routing
- Meets ATX 3.1 and PCIe 5.1 standards, making it future-proof for upcoming hardware
Common Complaints
- Capacitor failure leading to a loud bang and PSU death reported by multiple users
- PSU dying within days of installation, even under light load
- Lack of fan failure protection, a feature expected in a high-end unit
- The 180mm depth can make fitting into some cases challenging
Ownership Tips
- The 5V BOOST switch is a unique feature, but its practical impact on stability isn't widely discussed by users.
- The dual-color 12V-2x6 cables are a nice touch for aesthetics and identifying the correct connector.
- The iCOOL fan mode does keep it quiet during normal desktop use, but some users prefer the fan running constantly for peace of mind.
- The sheer number of connectors provided is extensive, accommodating complex builds.
Frequently Asked Questions
Does this PSU support the latest graphics cards?
Yes, it's fully compliant with ATX 3.1 and PCIe 5.1 standards, and includes two native 12V-2x6 cables with TempGuard for next-gen GPUs.
How quiet is the fan?
It uses a 135mm Fluid Dynamic Bearing fan with iCOOL Intelligent Fan Control. In iCOOL Mode ON, the fan stays off during low to medium loads, reducing noise. It only activates when load or temperature increases.
What does the 5V BOOST mode do?
The 5V BOOST mode increases the voltage level of the 5-volt rail to help it cope with increased loads, maintaining optimal performance. If no voltage drop occurs, it regulates the 5V rail to approximately 5.15V.
Is this power supply physically large?
Yes, it has dimensions of 180mm x 150mm x 86mm. The 180mm depth is larger than many standard PSUs, so check your case compatibility.
What kind of capacitors does it use?
It uses 100% highly reliable Japanese capacitors.
Buying Guide
When you're looking at a power supply, you're essentially buying the heart of your PC. It converts wall power into the specific voltages your components need. A higher wattage means it can supply more power, crucial for powerful CPUs and multiple graphics cards. Efficiency ratings like 80 PLUS Titanium tell you how much power is wasted as heat; Titanium is the best, meaning less waste and potentially lower electricity bills. ATX 3.1 and PCIe 5.1 compliance are critical for compatibility with the newest, most power-hungry GPUs, ensuring they get stable power without issues like power excursions.
Wattage (1650W)
This is the maximum power your PSU can deliver. Think of it like the horsepower of a car; more horsepower means it can handle heavier loads. 1650W is overkill for most systems, but essential for extreme setups with multiple high-end GPUs that can draw hundreds of watts each.
80 PLUS Titanium / Cybenetics Titanium
These are efficiency certifications. Titanium is the highest rating, meaning the PSU converts over 94% of AC power into usable DC power at typical loads. Less wasted energy means less heat generated by the PSU and potentially lower electricity costs over time, like a fuel-efficient engine.
ATX 3.1 & PCIe 5.1
These are the latest industry standards for power supplies. ATX 3.1 ensures better handling of transient power spikes (sudden, brief increases in power draw), which modern GPUs are known for. PCIe 5.1 refers to the new 12V-2x6 power connector, which delivers more power directly to graphics cards, preventing the need for multiple older 8-pin cables.
Fully Modular
This means you only plug in the cables you need. It's like having custom-length cables for your car's engine; it keeps the inside of your PC much tidier, improves airflow, and makes building or upgrading easier compared to having a spaghetti mess of unused, permanently attached cables.
Alternatives
If you don't need 1650W, look for ATX 3.1 and PCIe 5.1 PSUs in the 850W-1200W range with 80 PLUS Platinum or Gold efficiency, ensuring you still get modern features without the extreme wattage.
