Review: A Tier rated PSU on the SPL charts at a great price. - Pros, 1. It's a 1200w 80+ Gold power of course. 2. It has the new ATX 3.1 and PCIE 3.1 standard. 3. It has the new 12v 2x6 connector fir the newest GPUs(especially from Nvidia). 4. Has pretty of connections for most PC components. 5. The fan isn't too loud and it's surprisingly cool(see cons). 6. It has an Eco switch(though I don't use it). 7. This PSU will handle a GPU like an RTX 5090. I'm currently running a RTX 5090 with no issue at the moment(only time will tell). 8. It's a sturdy PSU, yet smaller in size. This made routing the cables so much easier. 9. Lastly the price. For what you get and tge quality this would be extremely hard to beat even if it's competition was running a sale. It's not impossible to beat because some may need some better and/or different where the price isn't justified. Cons, 1. The intake area isn't the most ventilated. I'm actually surprised it stays as cool as it does. Perhaps because I'm not majorly pushing my PC's power limit. 2. The fan could be a little better, but it seems to do the job. 3. I wish some of the cables were braided rather than using flat plastic coated wire. The coated wire maybe easier to route, but I'm skeptical of it's durability and I was cautious when installing this PSU because of this. 4. If your PC is running something like a RTX 5090(especially with a last generation Intel I7s or I9s) I'd advise undervolting your GPU. I will put less risk on your 12v cable, reduce any coil whine and possibly make PSU and other components last longer.
Review: Best 1200w PSU you can get for this price - Best 1200w PSU you can get for the price, but has it's pros and cons + Delivers 1200w + Small and fits perfectly into Geometric Future M5 case + Best for the price - Cables are stiff and not braided - Loud under load It works for me, but you can spend x2 and x3 and get something quieter with better cables

### ⭐⭐⭐⭐⭐ Best 1200w PSU you can get for this price

Best 1200w PSU you can get for the price, but has it's pros and cons + Delivers 1200w + Small and fits perfectly into Geometric Future M5 case + Best for the price - Cables are stiff and not braided - Loud under load It works for me, but you can spend x2 and x3 and get something quieter with better cables

### ⭐⭐⭐⭐⭐ Powerful PSU for an excellent price
*by S***K on October 2, 2025*

I have no complaints at all about this PSU. Fits well in their Montech XR case and super easy to install. It simply slides right in the bottom and secures with screws. No noise that I can hear and it's also overkill for my build. Mainly bought this to support more demanding hardware in the future. Given it's price, I'd recommend it simply for the headroom and greater efficiency it'll have at lower loads. This sometimes can lead to a longer lifespan for the power supply as it'll run much more cool. Fully modular with plenty of extra cable ties and straps and all the cables you'll need. Remember to never reuse cables between power supplies. Keep them separated in their boxes if you build multiple computers.
