a friend told me that my FX 750 W ) is bad for the pieces that im going to have , the new specs are:
I7 7700K
16 GB RAM (2400mhz)
GTX 1060 MSI 6G
Asus PRIME B250-PRO
I7 7700K
16 GB RAM (2400mhz)
GTX 1060 MSI 6G
Asus PRIME B250-PRO
The label says the 12V rail is rated for 60A, which is pretty decent. On the other hand, it only has 2 PCIe power connectors, which is kinda low for a 750W unit and might indicate it isn't quite capable of (safely) delivering all the power it promises.
I just wanna know if my computer is going to work good
It's impossible to say for sure. If you want to be sure it's safe, you'd have to buy another one that's actually been tested.
