AI Verdict
An 850-watt ATX 3.1, PCIe 5.1 ready, 80 Plus Gold power supply with 105°C Japanese capacitors and a 150mm fan, aimed at budget-conscious PC builders.
This 850-watt ATX 3.1 power supply with 80 Plus Gold efficiency and native 12VHPWR cables is a strong contender for modern gaming builds, especially given its compact 150mm size. However, the brand's newer status in the PSU market means it might not be the first choice for users prioritizing established brand reputation over features and price.
If brand reputation is a primary concern, look for PSUs with similar wattage and ATX 3.1 compliance from more established manufacturers, often indicated by longer warranty periods.

What Buyers Say
User feedback on the darkFlash PMT850 is limited but points to a functional unit, with one Reddit user reporting it 'still working fineee' after a year of use. However, there's a noticeable undercurrent of skepticism on Reddit regarding darkFlash PSUs due to the brand's relative newness in the power supply market. While some sources list it as an 'A tier' PSU, this doesn't fully alleviate concerns about long-term reliability for some potential buyers.
“Look, I needed a new PSU for my 4070 Super and this thing had the 12VHPWR cable and was actually in stock for a decent price. It's been running my rig for a few months, no explosions yet, so I guess it's doing its job.”
Common Praise
- The fully modular design helps keep PC builds tidy and improves airflow.
- The inclusion of a native 12VHPWR cable is convenient for newer GPUs.
- Its compact 150mm size makes it easier to fit into various PC cases.
- The 80 Plus Gold efficiency rating is appreciated for reducing electricity costs.
Common Complaints
- Some users express general distrust or hesitation towards darkFlash as a PSU brand due to its newer market presence.
- Lack of extensive long-term user reviews makes it harder to gauge durability beyond the 5-year warranty period.
Ownership Tips
- The compact 150mm length really does make a difference in smaller cases, giving more room for cable routing behind the motherboard tray.
- The fan is indeed quiet, and I haven't noticed it spinning up aggressively even during gaming sessions.
- The modular cables are stiff initially, but they flatten out after being routed for a while.
- The 12VHPWR cable feels secure when plugged into the GPU, no wobbling or concerns about connection.

Buying Guide
When you're looking at a power supply, you're basically buying the heart of your PC. It needs to deliver enough juice to all your components, especially your graphics card, without breaking a sweat. You want to make sure it's efficient so you're not wasting electricity, and that it has the right connectors for your current and future parts.
Wattage (850 watts)
This is how much power the PSU can deliver. Think of it like the horsepower of a car; you need enough to run all your components smoothly, especially power-hungry graphics cards and CPUs. Too little, and your system can crash; too much, and you're just paying for unused capacity.
80 PLUS Gold Efficiency
This rating tells you how much power from the wall actually reaches your components, versus how much is lost as heat. Gold means 87-90% efficient, so less wasted electricity and less heat inside your case, which is like getting more miles per gallon in your car.
ATX 3.1 & PCIe 5.1 Ready
These are the latest standards for power supplies, designed to handle the power spikes of modern graphics cards. It's like having a modern electrical system in your house that can handle all your new appliances without blowing a fuse, ensuring your GPU gets stable power when it needs it most.
Fully Modular Design
This means you only plug in the cables you actually need for your components. It's like having custom-length cables for everything, making your PC build much cleaner, improving airflow, and making future upgrades or troubleshooting way easier than dealing with a tangled mess of unused wires.
Alternatives
If this PSU doesn't fit, consider looking for other 850W ATX 3.1 power supplies with 80 Plus Gold or Platinum efficiency, especially if you want a longer warranty or prefer a brand with a more established track record in the PSU market.
