As we mentioned earlier this board is definitely for the graphics and power hungry systems. We can see 3 PCI-E 6 pin connectors and 3 PCI-E 8 pin connectors which essentially means you could power 6 video cards or three dual plug heavy hitting cards. We are suprised to see manufacturers still including floppy power connectors on PSU’s these days. Can you even buy systems with a floppy drive any more?  For motherboard power you will be happy to see that the 1050 Ultra X4 has both a 4 and 8 pin power connector for modern and server systems which require these connectors. Those with a lot of hard drives are not let down either with a grand total of 11 SATA power connectors. Good luck finding ways to cram 11 hard drives into a case, a even better luck moving the heat generated by that many drives.

Now lets take a closer look at this power supply and see what you can expect inside the box.
