A tier on ZTT PSU tier list, great price, plenty og PCIe GPU connectors.
Great PSU so far. Great price and got A on ZTT/SPL's PSU tier list. Would buy again. If this is what you're looking for, it's great quality (apparently) for a great price. Buy it. Also love that it has enough PCIe GPU connectors for my soon-to-be multi-GPU home server.

Great PSU
Great quality well packed by scan and the manufacturer so arrived in perfect condition. All the cables are labeled nicely. No issues with installation, just a shame my case mostly hides the nice design 😀

Just read the professional reviews. Stellar unit. Incredible price to performance. Only possible caveat is it's longevity. We'll see...

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.

Good value, stable voltages, but LOUD under any type of load! Something is either wrong with the fan configuration or maybe with the fan itself, I just know that it is obscenely loud in comparison to the rest of my computer fans, if your GPU starts pulling ANYTHING over 220W, you WILL hear this PSU guaranteed (at least you'll know if it's working or not). I'm gonna keep it because outside of that, it was a pretty good deal, just a shame I have to mod it in order to have a silent PSU

The PSU IS GREAT! This psu provides great value for money, making budget builds perfect especially for its wattage it supplies power to everything perfectly with no issues whatsoever, it is very quiet and makes 0 noise at all, no coil whine or anything cables were also in perfect condition. Overall great psu i'd highly recommend buying it.

Got this one at sale for 63USD. a steal for a A tier PSU with full Japanese capacitors, 10y warranty, silent fan. I rcm this PSU especially at this sale price. you won't have any better option at this price point.
