After pressing the power button on the PC case or on the mother board, the system does not boot up. No Dr Debug code, no fan starts spinning, and no beep sound. Only the mother board LED flashes in red color. I have tried to reconnect the 24pin ATX cable, 8pin cpu cable and 4pin cpu cable but nothing changed. CPU: 1950X MB: X399 Gaming PSU: Corsair RM850i and RM650x Memory: G.SKILL 4x8GB 3200 C14 Graphic Card: Asus 1050 Ti SSD: Samsung 960 Pro 512 GB |

" rel="nofollow - I noticed a similar issue has been reported before: http://forum.asrock.com/forum_posts.asp?TID=6211&PN=2&title=x399-taichi-wont-boot-up shlashly finally power up his system by changing his power supply to EVGA 750 G3. Initially I was using RM650x and I thought this is the same issue. But after I replaced it by RM850i, nothing changed at all.

I'd suggest you take out all of the components out. Check and re-seat all power cables. Take the mobo out of the case and lay it on a non-conductive material, e.g. wood, cardboard, etc. After all this, take out the CPU and check for bent pins in the socket. Re-seat the CPU, its cooler and 1 stick of RAM. Clear the CMOS by taking out the battery, PSU power cord and pressing power on button for 10s. Put the battery back, plug the PSU power cord in the wall socket. If you don't get any beeps or Dr.Debug codes during boot now, I'd say it's RMA time. ------------- 1700X ZP-B1 (stock); X370 Taichi (UEFI 3.10); 16GB F4-3200C14-8GFX XMP; 256GB 960 EVO; RX 580 NITRO+ 8GB |

" rel="nofollow - Bexley, I assume that RM850i means 850 Watts. I have a similar system and suggest you stick to the 850 Watt supply. Please get down to minimum by removing all but one stick of memory and video card-no SSD, no HDD, etc. Is this really all the storage you have? I would rather see your specifications in your signature as I have them. Make sure the 8-pin and 4-pin power cables plugged into the the CPU area of the board are CPU and not PCIe and the cables plugged into the video card are not CPU. Also make sure the 4-pin cables are not rotated 90 degrees. We have seen that more than once. You can also remove the video card and see if it will power up and POST. Thanks and enjoy, John. ------------- Fat1 X399 Pro Gaming, TR 1950X, RAID0 3xSamsung SSD 960 EVO, G.SKILL FlareX F4-3200C14Q-32GFX, Win 10 x64 Pro, Enermx Platimax 850, Enermx Liqtech TR4 CPU Cooler, Radeon RX580, BIOS 2.00, 2xHDDs WD |

" rel="nofollow - Will the mother board post with only one stick of memory? In the manual, it shows two sticks must be installed in A2 and B2 to activate dual channel.

You do not need dual channel enabled to boot so yes, you can post with one RAM module installed. -------------

to re post above advice this problem is usually a case of the power connectors being incorrect please triple check the board power connectors are ALL cpu/eps labelled and connected in correct orientation (its easier to look at the lip on the board connector and the clip on the power lead ) allthough the different shapes are the designed way to orientate the leads ------------- [url=https://valid.x86.fr/jpg250]  [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |

probably the board itself. test the other parts in a known good setup to rule in parts being good. putting parts in a bad board can kill the parts. ------------- MB: X399 Taichi, UEFI L3.32 VGA: EVGA 1080 Ti FTW3 PSU: Seasonic PRIME 1300 W PLATINUM CPU: AMD Ryzen Threadripper 2950X MEM: 4x16GB, 3600MHz G.Skill Trident Z F4-3600C17Q-64GTZKW |

" rel="nofollow - Surely these boards pass QC and startup post tests before they're shipped? Can we see a photo of your board with the power connectors attached? |

Just returned this mother board to the PC store this morning. A guy tested the board and also could not boot it up. He then swapped my CPU to a spare Taichi board and it worked straightway. I have filled in a form and will get a new pro gaming board next week since it is currently out stock. ------------- TR4 1950X, X399 Pro Gaming, G.SKILL Flare X F4-3200C14D-16GFX, Corsair RM850i, Samsung 960Pro M.2 512GB, ASUS GeForce 1050 Ti, Corsair H100i v2, Corsair Obsidian 750D, WD Red Nas 8TB |

I am also surprised this time. I have never seen that a brand new PC parts is faulty since 1999 when I started building up my PCs.
