Pros
- Supports ATX 3.1 and PCIe 5.1 standards, including a 12V-2x6 cable for modern GPUs.
- Boasts 80 Plus Gold and Cybenetics Platinum efficiency certifications, indicating high power efficiency.
- Includes a 10-year warranty, providing extended coverage for component failures.
- Features 100% Japanese capacitors, contributing to long-term stability and reliability.
- Equipped with a 135mm Fluid Dynamic Bearing fan with Smart Zero Fan mode for quiet operation under low loads.
- Delivers excellent voltage ripple suppression, with 12V rail ripple at 30 mV, well below ATX limits.
Cons
- Only includes one 12V-2x6 connector, which might be limiting for future dual high-end GPU setups.
- Six PCIe connectors share three cables in pairs, which could lead to less optimal cable routing or power delivery for multiple high-draw components.
- Voltage regulation is slightly above 1% across all rails (12V: 1.1%, 5V: 1.4%, 3.3V: 1.2%), which is not top-tier but still very good for its class.
- The 10-year warranty explicitly excludes power supplies used for cryptocurrency mining.
Dimension Scores
It holds both 80 Plus Gold and Cybenetics Platinum certifications, indicating very high efficiency across various load levels.
The 135mm FDB fan with Smart Zero Fan mode ensures quiet operation, with Cybenetics giving it an A- Noise rating.
The use of 100% Japanese capacitors and comprehensive protection features (OCP, OVP, UVP, SCP, OTP, OPP) points to a robust internal design.
Its fully modular design and flat cables aid in clean builds, though the single 12V-2x6 connector and shared PCIe cables are minor limitations.
Best For
- High-end gaming PCs with a single power-hungry GPU like an RTX 4080 or 4090.
- Future-proofing a build for upcoming ATX 3.1 and PCIe 5.1 components.
- Users prioritizing energy efficiency and a quiet system during light use.
Not Recommended For
- Workstations or mining rigs running multiple high-end GPUs that require more than one 12V-2x6 connector.
- Budget-constrained builds where a lower wattage or less efficient PSU would suffice.
Watch Out For
- You only get one 12V-2x6 cable, so if your future GPU setup needs two, you'll be out of luck without an adapter or a different PSU.
- The six 6+2 pin PCIe connectors are paired on three cables, which can make cable management a bit trickier if you have several components needing dedicated lines.
- The 10-year warranty doesn't cover use in cryptocurrency mining, so don't plan on using it for that.
- While compact at 140mm, some users have reported issues with noise or unit failure, though these appear to be isolated incidents.

What Buyers Say
What's really popping up in user feedback is how much bang for your buck this PSU offers, especially considering its ATX 3.1 and PCIe 5.1 readiness. People are consistently pointing out the quiet fan operation and the peace of mind from the 10-year warranty. While most agree on its performance, a few have mentioned wishing for more than one 12V-2x6 connector for really beefy setups.
“I was kinda nervous about a Montech PSU but this thing is a beast for the price, my 4080 is happy and it's so quiet I forget it's even on.”
Common Praise
- The 10-year warranty makes you feel really secure about the purchase.
- It's surprisingly quiet, especially with the fan not spinning up during light use.
- The price for a 1050W ATX 3.1 unit is really competitive.
- The fully modular design with flat cables makes building and cable routing much cleaner.
- It handles modern high-power GPUs without breaking a sweat.
Common Complaints
- Only having one 12V-2x6 connector feels a bit restrictive for a 1050W unit.
- The PCIe cables being paired on three lines can make things a bit messy if you have a lot of components.
- Some isolated reports of units being loud or failing, though these seem to be outliers.
- The warranty not covering crypto mining is a bummer for some.
Ownership Tips
- The fan really does stay off most of the time, keeping the system super quiet when just browsing or doing light work.
- Cable quality feels sturdy, and the flat design is a lifesaver for routing behind the motherboard tray.
- Even under heavy gaming loads, it stays cool and doesn't get noticeably loud.
- The single 12V-2x6 cable is long enough to reach the GPU comfortably in a mid-tower case.
Frequently Asked Questions
Does this PSU come with the new 12V-2x6 cable?
Yes, it includes one 12V-2x6 cable, making it compatible with the latest PCIe 5.1 graphics cards.
Is this power supply fully modular?
Absolutely, it's fully modular, meaning you only connect the cables you need, which helps keep your build tidy.
How quiet is this power supply?
It features a 135mm Fluid Dynamic Bearing fan with a Smart Zero Fan mode, so the fan won't spin up until a certain load, keeping it silent during lighter tasks.
What kind of warranty does it have?
Montech backs this PSU with a 10-year warranty, covering defects and issues for a long time.
Is it good for high-end gaming?
With 1050 watts, ATX 3.1 compliance, and a 12V-2x6 cable, it's designed to handle high-end gaming systems, especially those with powerful GPUs.
Buying Guide
When you're looking at a power supply, you're basically picking the heart of your PC. You need enough wattage to power all your components, especially your graphics card, and you want it to be efficient so it doesn't waste electricity and generate a ton of heat. Modern PSUs also need to keep up with new standards like ATX 3.1 and PCIe 5.1 to ensure compatibility with the latest GPUs. This Montech unit hits those marks.
Wattage (1050W)
This is how much power the PSU can deliver. Think of it like the horsepower of a car; more wattage means it can handle more demanding components, especially high-end graphics cards and CPUs, without struggling. 1050W is a lot, so it's ready for serious gaming rigs.
80 Plus Gold & Cybenetics Platinum
These are efficiency ratings. They tell you how much power the PSU draws from the wall versus how much it actually delivers to your components. Gold and Platinum are very high, meaning less wasted energy as heat and lower electricity bills over time.
ATX 3.1 & PCIe 5.1 Ready with 12V-2x6 Cable
This is crucial for modern systems. ATX 3.1 is the latest power supply standard, and PCIe 5.1 with the 12V-2x6 cable is specifically designed to provide stable, high power to the newest, most power-hungry graphics cards without needing clunky adapters. It's like having the right plug for the newest appliance.
Fully Modular
This means you only plug in the cables you actually need for your components. It's a huge win for cable management, making your PC build look much cleaner and improving airflow inside your case. No more tangled mess of unused cables.
Alternatives
If this wattage is overkill or you need more than one 12V-2x6 connector, look for PSUs with lower wattage (e.g., 850W) for less demanding systems, or higher-end units that explicitly state multiple 12V-2x6 outputs.
