Dimension Scores
The 1000-watt output combined with 80 PLUS Gold and Cybenetics Gold certifications demonstrates high efficiency and ample power delivery.
The 135mm fluid dynamic bearing fan with Zero Fan Mode for loads under 50% and a Cybenetics A Noise Level rating indicate very low noise during typical use.
The use of 100% premium Japanese capacitors, which improve hold-up time and minimize ripple noise, points to a high-quality internal construction.
It's fully modular, which is great for reducing clutter, but user reports of 'notoriously stiff' cables slightly detract from perfect cable routing ease.
Best For
- New PC builds featuring high-end NVIDIA RTX 40 or 50 Series GPUs.
- Users upgrading to power-hungry components who need ATX 3.1 compliance and a 12V-2x6 connector.
- Anyone prioritizing quiet operation during light to moderate system loads.
Not Recommended For
- Budget-focused builds where 1000 watts and ATX 3.1 features are overkill.
- Compact Small Form Factor (SFF) cases where the ATX form factor might be too large or cable stiffness becomes a major issue.
- Users who frequently swap out cables and prefer broad third-party cable compatibility.
Watch Out For
- The included cables are 'notoriously stiff,' which can make routing and tidying them up a real pain, especially in smaller cases.
- Inserting the 12VHPWR cable can be tricky; users have reported it's hard to get it fully seated, risking damage to the PSU if not done perfectly.
- While it has a Zero Fan Mode, some users found it gets 'a bit noisy' when the system is under heavy load, which might bother you if you're chasing a truly silent rig.
- Despite a 10-year warranty, some buyers have found NZXT's customer service 'lacking' when issues arise.
- There's a reported 'blip in efficiency' around 50W on Cybenetics graphs, though its real-world impact is debated among users.

What Buyers Say
What really stands out is the ATX 3.1 compliance and the dedicated 12V-2x6 connector, which means this PSU is ready for the latest power-hungry GPUs, delivering up to 600 watts directly. However, a recurring theme in user feedback is the stiffness of the cables, which can turn cable management into a wrestling match. Some folks also mentioned that while it's silent at low loads, it can get a bit noisy when your system is really pushing it. The 10-year warranty is a big plus, though a few users wished for better customer service when they actually needed it.
“Man, this thing powers my 4090 like a champ, but seriously, the cables are like trying to bend rebar, my fingers hurt after routing them.”
Common Praise
- The 12V-2x6 cable is a lifesaver for new RTX 40/50 series cards, no more adapters.
- Zero Fan Mode keeps things dead silent when I'm just browsing or doing light work.
- The fully modular design makes building so much cleaner, only plug in what you need.
- Feels really well-built, the Japanese capacitors give me peace of mind about longevity.
- Handles power spikes from my GPU without a hitch, very stable power delivery.
Common Complaints
- These cables are so stiff, trying to bend them for a clean look was a nightmare.
- Had a tough time getting the 12VHPWR cable to click in all the way, felt like I was going to break it.
- It gets pretty loud when my GPU is under full load, definitely not 'low-noise' then.
- Tried to use custom cables but the proprietary connectors made it impossible.
- The customer support wasn't super helpful when I had a question about a minor issue.
Ownership Tips
- The Zero Fan Mode is legit, my PC is completely silent until I fire up a game.
- Cable combs are a must-have if you want any semblance of neatness with these stiff cables.
- The 12V-2x6 connector is super convenient, but double-check that it's fully seated every time.
- Even though it's 1000W, it's not overly huge, fits fine in my mid-tower.
- The matte black finish looks really clean and blends into my build.
Frequently Asked Questions
Does this PSU come with the new 12V-2x6 cable for RTX 40 Series GPUs?
Yes, it includes a durable, heat-resistant 12V-2x6 connector that can deliver up to 600 watts, specifically designed for NVIDIA GeForce RTX 40 and 50 Series graphics cards.
Is this power supply quiet during normal use?
It features a 135mm fluid dynamic bearing fan with Zero Fan Mode, meaning the fan stops spinning completely when the power supply is under 50% load, making it silent during light to moderate use.
What does 'ATX 3.1 compliant' mean for my PC?
ATX 3.1 compliance ensures the power supply can handle the transient power spikes of modern high-performance components, especially GPUs, providing better stability and efficiency for your system.
What kind of warranty does this power supply have?
NZXT backs this power supply with a 10-year warranty, which is standard for high-quality PSUs in this category.
Are the cables flexible for easy routing?
User feedback indicates the cables are 'notoriously stiff,' which might make cable management a bit challenging, especially in compact cases.
Buying Guide
When you're looking at a power supply, you're essentially picking the heart of your PC. You need enough wattage to feed all your components, especially your graphics card and CPU. The efficiency rating, like 80 PLUS Gold, tells you how much power is wasted as heat; higher efficiency means less wasted electricity and less heat inside your case. For modern high-end GPUs, ATX 3.1 compliance and a 12V-2x6 connector are crucial for stable power delivery and to avoid using clunky adapters.
Wattage (1000 watts)
This is the total power your PSU can supply. Think of it like the engine size in a car; you need enough horsepower to move everything you're carrying. For a high-end gaming PC with a powerful GPU and CPU, 1000 watts provides plenty of headroom and stability.
80 PLUS Gold
This certification means the PSU is at least 87% efficient at 20% load, 90% at 50% load, and 87% at 100% load. It's like getting better gas mileage; less power is wasted as heat, saving you a tiny bit on your electricity bill and keeping your PC cooler.
ATX 3.1 & 12V-2x6 Connector
This is the latest standard for power supplies, specifically designed to handle the massive, sudden power draws (transient spikes) of modern graphics cards like the RTX 40 and 50 series. The 12V-2x6 connector is the direct cable for these new GPUs, eliminating the need for multiple 8-pin adapters and ensuring stable power delivery up to 600 watts.
Fully Modular
This means all the cables detach from the power supply. It's like having a custom-built wardrobe where you only put in the shelves and drawers you need. You only connect the cables your components require, which makes for a much cleaner build with better airflow inside your PC case.
Alternatives
If this PSU doesn't quite fit, look for other ATX 3.1 compliant power supplies with an 80 PLUS Gold or Platinum rating, and adjust the wattage based on your specific GPU and CPU power requirements. If cable flexibility is a top priority, search for reviews that specifically mention soft, pliable cables.
