I would recommend this item.

### ⭐⭐⭐⭐ Good
*by S***R on 16 July 2025*

Only comes with one 6+2 pcie cable and another Another 8 pin but 4 go to the power for the cpu depending on your motherboard . In my case 4 pins went to the cpu which left me with a 8 pin and a 4 pin which left me with no cable to power my 14 pin gtx 980ti. Although this psu is highly recommended and performs good it lacks some cables depending on your situation.
