Hi,
I am fine with my targeted GPU power consumption ranges OC'ed or not but not system parts in detail.
It seems that the overall systems are bound to consume between 150W-200W ? but what about each components separatly :
- 6/8 GPUs motherboard w/ 4 Gb DDR4
- G3930 Kaby Lake CPU
- 128Gb SSD
- USB risers, each
With that knowledge, I could eventually split the load between 2 PSUs instead of 1 when I'm short of power, but is it really recommended ?
Thanks for help
I'm finding your post a little difficult to understand. 150W-200W for an "overall system" with 6-8 GPUs is far too low of an estimate for power draw under load, unless your GPUs are super underpowered ones that probably aren't worth mining with.
It's typical to use the TDPs of each component when estimating overall power use in order to figure out how to best distribute load between two power supplies, and then making sure that the estimate for each PSU doesn't exceed about 70% of its respective rating.
Celeron G3930 TDP: Roughly 50W
128GB SSD: Small, essentially a rounding error.
USB risers: Small, essentially a rounding error. (The risers themselves do not use much power. The graphics cards draw some power through the risers, but the exact amount varies by card and is difficult to determine. Each card draws some power directly from the PSU via the onboard 6 and/or 8 pin PCIe connectors, and some power through the x16 slot.)
Graphics cards: What cards do you have?
Fudge factor about 50W extra for the primary PSU that will be powering the motherboard. (With the 24 pin connector and the 4 or 8 pin EPS12V connector.)
