★★★★★I am very happy and satisfied with this purchase.

I bought an RTX 5070 Ti and installed this power supply to support the card's power requirements. Apparently, the PSU has plenty of power to spare—which will allow for future upgrades. I am very happy and satisfied with this purchase.

★★★★★Best psu ever!

No need to buy fancy cables and it works beautifully.

★★★★★Great product, read the directions

No issues so far. It’s a power supply. Only weird feature is that you can control the fan speed via a physical dial on the power supply. I didn’t realize this so I had the fan off for the first few months of owning it and my PC got pretty hot
