1  Alternate cryptocurrencies / Mining (Altcoins) / Re: Gigabyte GTX 1070 ITX - Problems? on: August 04, 2020, 12:41:37 PM
Here we go...



Any idea on the full spec of that fuse?
I'm thinking of just soldering an external fuse holder.

This is the exact issue 2 cards have had already and shipping it back for RMA just to replace the fuse seems ridiculous. Rather not waste my money on shipping since fuses are much cheaper.

No exact spec sorry. My educated guess would be a fast blow 10A ceramic fuse in a 1206 SMT package. Something like this should work just fine: https://www.digikey.com/product-detail/en/bel-fuse-inc/0685H9100-01/507-1942-1-ND/5466714

I'll probably order ten or so since they're cheap...

My only 1070 ITX with this issue (out of 8 total) is still going strong and i still have that cheap multimeter acting as a fuse on it because I have other things to do. It's also fun to watch current readings fluctuate around 6.0A Smiley

So I guess this was not the same issue on mine.
The fuse is blown, but there seems to be a more serious underlying cause. The PSU instantly went into a protect mode if I shorted across the fuse.
Wouldn't doubt if I made things worse.

Well, looks like they had a reason to put the fuse in there after all. And I will repeat myself by saying that I've never seen a regular fuse on any of the other 1070's where I can actually see the parts, i.e. open back. Sounds like an afterthought on Gigabyte part and a cheap choice of fuse to boot.
I bought a card that turns out to be dead (no signal, no fan). so pretty likely it is this exact issue. See this Ghetto repair, looks promising: https://www.reddit.com/r/pcmasterrace/comments/9wlcse/ghetto_fuse_repair_on_gigabyte_gtx_1070_mini_itx/

I am looking for a more refined fix though Wink I am not an electrics expert, but why not replace this with the same parts that you mention for other 1070s?

- Polyfuse like your other (Gigabyte Mini?) 1070s seem to have?
- Low ohm current sensing resistor? 

Or does this not fit into the rest of the Gigabytes 1070 Mini circuitry?
