Hi everyone, I haven't built a PC in many years and was just wondering on what you guys think of my following build. Case: Fractal Design S2 Power Supply: Corsair HX850i Motherboard: Gigabyte Z390 Aorus Pro WiFi CPU: Intel i9 9700k CPU Cooler: Corsair H150i Hard Drive: Samsung 970 Evo Plus 1TB GFX Card: Gigabyte Geforce RTX2060 6GB Windforce OC RAM: Corsair Vengeance RGB Pro 16GB DDR4 3200MHz C16 XMP2 I have yet to build this system but have all the parts. I have a couple of questions if any one can advise. 1, The Motherboard has 2 ATX Power Connectors 1, 8pin ATX and 1, 4 pin connectors, but my power supply does not have the 4 pin 12v connector, does this 4 pin connector have to be used or is this only for over clocking. 2, does this motherboard support the i9 9900k CPU if it come with an early Bios revision. 3, Anyone had any problems with this RAM.
