Hello!
So I've been helping out a friend to put together a PC build. I recommended these components to him:
CPU: Core i7-8700K
CPU Cooler: be quiet! DARK ROCK TF
Motherboard: MSI Z370 TOMAHAWK
Memory: Patriot Viper 4 (2 x 8GB) DDR4-3400
SSD: MyDigitalSSD BPX 256GB M.2-2280
HDD: Western Digital Gold 1TB 3.5″
Video Card: Aorus GTX 1080 Ti Xtreme Edition 11G
Power Supply: Corsair RMx 650W 80+ Gold
We live in different countries, so I was instructing him to put everything together over e-mails. He already built a PC once before, but it was 10 years ago, so he was a bit rusty. He seemed to handle it fine, in the end.
However, he had issues starting his PC, quoting:
"The computer wasn’t starting up, so I took it to a repair shop. There is not nearly enough power to run that GPU and everything else. This was diagnosed by removing the GPU, which allowed for enough power to run the CPU. The repairman recommended at least a 1000 watt psu."
This sounds completely asinine to me. Before suggesting the build, I've checked reviews for Power Consumption:
Power Consumption shouldn't exceed 130 Watt for CPU and 330 Watt for GPU, and that's after overclocking, which he didn't even begin doing. When combined, a 650 Watt PSU still has 190 Watt left to handle the rest of the system and provide some headroom, if it's needed.
Even a Power Supply Calculator at BeQuiet's site says 440 Watt for that build, including overclocking, granted it uses FE as a reference so it's gonna say a bit lower.
So I still think "not enough Watts" is a complete nonsense, but the PC did fail to start. And it was able to start after GPU was removed, if we're to believe the repiarman.
So what could be the issue? Faulty GPU? Faulty Power Supply? Faulty Motherboard?
EDIT: I talked a bit with the friend, and he did say that PC was able to boot into BIOS after the Graphics Card was pulled out, which means he did properly connect the CPU Power to Motherboard, and he did confirm that he used two separate cables for PCI-Express Power.
