well to answer your question yes this unit has 2 cables and 4x 6+2 pcie connectors
which is plenty for any graphics card using this type of cable/connector ,
it also has the new 12VHPWR standard for latest nvidia video cards .
(although this particular model is limited to 450w via this single connector and not the full 600w of power -
which if you ask me is actually a good thing on such a unit with older and less fail safe
revision of this connector ,
it may prevent you from running rtx 4090/5090 on it in the future but it is a fair trade in this case)
bottom line - this unit is solid , although it would not be my first pick
when shoppping for a new 850w/1kW power supply
(of course it largely depends on your location and
what your other options may be and also on the pricing of course)
