Problem with startup on initial installation
I made some changes to your notes to improve clarity. The attached files are ready, and I clarified a few points about the PSU cables, connectors, and the motherboard components you mentioned.
there are three types of cables featuring 8 pins female—CPU/EPS and PCIE. The CPU/EPS can be divided into two sections, each with four pins. The PCIE can be split into a single 6-pin and another 2-pin version. On the PSU side, both connectors match the standard design and support eight pins, but they cannot be swapped. One side is labeled for CPU or EPS, while the other is for PCIE. Both versions are non-splittable, with distinct markings inside the connectors to prevent incorrect usage. The exception is the CPU itself, which uses an 8-pin connector that fits correctly regardless of orientation. Some users have placed a PCIe cable in the middle instead of using it properly. Always check the labeling on the contacts—indicating whether it's for CPU, EPS, or PSU. It’s crucial to follow the manual carefully; incorrect connections risk damaging components. The pin-out layout on the PSU side isn’t uniform, so mixing modular PSU cables between units can cause shorts, potentially harming your mainboard, GPU, or powered devices. In your case, there doesn’t appear to be a CPU/EPS cable visible in the images—look for it near the CPU and external ports instead.
I turned off and took apart most of the system to create space and double-check myself about the PSU cables. My PSU has two 8-pin CPU connectors: one labeled PCIe (6+2 to 8 pins) and another dual 6+2 to 8-pin. Which one should I use for connecting to the GPU? Also, thank you for your assistance.
Your GPU requires a PCIe cable while your CPU needs a CPU cable. Both will link to the same PCIe/CPU bank in your power supply, which appears identical but differs on the device side. Some motherboards offer two CPU connectors—either four or eight pins, sometimes mixing types. Certain models have one 6-pin or 8-pin connector, while others provide both. Some cards even feature three 8-pin connectors. It all hinges on the card's power draw and the PSU's capacity. A single PCIe 8-pin connector can supply around 150 watts, but a typical PSU might deliver about 250 watts. The 6-pin connector usually handles roughly 85 watts. Some cables include two 6+2 pin connectors at the end—known as pigtails. For cards with two 8-pin ports, one cable may not provide sufficient power since they can draw up to 300 watts, but the PSU is limited to around 250 watts. Lower-end cards like X050-X070 often work fine, featuring both 6+8 pin sockets on the GPU. If your GPU has two 8-pin connectors, it’s wise to use two separate cables from the PSU for optimal performance. You only have one 8-pin, but keeping this in mind is helpful for future upgrades.
Confirming the required 6+2 cable—does it have the PCI label? Also, is the absence of the inner housing on the 8-pin PSU side a concern?
The CPU cable likely has all its pins connected, while most PCIe cables don't. If you look at the ribbon cable, you might notice that certain PCIe cables have all eight pins filled in. I’d prefer those. I haven’t had time to verify, but the two-pin section is typically used for ground and power. Some manufacturers reduce it to just one ground side on the other side.
I cherish you deeply. I believe I've fixed my setup ten times over, mostly because of the wrong PSU cables I used—I'm glad I avoided any damage. It posted. You're truly a king. Where should contributions and presents be directed?
