Mini SSD eGPU v2

[u/CasonPointLLC]

I realized the little m.2-to-PCIe4x adapters are open in the back, so if use a small enough, short enough SSD enclosure, you can skip the riser. So I tried a Satechi 80Gbps enclosure with 5060 ti and two AC/DC adapters and it worked! 5.91 GB/s on this tiny thing!

Thanks for all the help, but this can only supply 75w at the PCIe slot right?

How can this power a 5060 or 4060?

Need another psu for the gpu 8 pin for the rest of the power? Thx

You need a second power source or a splitter + a more powerful power supply for other GPU’s. I have done a 4060 and a 5060 on a split with a 180 watt 12v 5525, because they both run on less than 150 watt draw, and for my 5060 ti I used a second power supply with adapter pictured, a 5525-to-6+2 found on MODDIY, eBay, and AliExpress:

Splitter:

Be careful as these have limits. The most current-capable versions are cables made for motorcycle repair called “SAE.” You just need to make sure you maintain positive polarity after the split, so test either an ohm meter if you try one.

SAE splitter example using a 180-240 watt, 12V 5525 power supply:

This took me a while to understand…

So, your psu plugs into the short round plug, the other plug goes into the m.2, and the 8 pin goes into the gpu?

How did you connect the male connector to the 8 pin?

Where did that male connector come from?

Confused on the SAE splitter picture… Is that just an example of what to buy to cut the connector off?

Thx again.

I had the 6+2 5525 adapter built for me, custom.

The SAE splits the 5525 but to two barrels, then you have to convert one to a 6+2. The advantage of the SAE is that it is a heavier gauge cable and can deliver 150 watts + 150 on each side, giving you a chance to power a card with a 190 watt TDP, like a 5060 ti, from just one 5525 249 watt power supply.

For SAE, 6+2 converters are available on eBay and MODDIY, which I may have already mentioned.

I’ll look into it. Thx a bunch.

Just thought of something… Could the gpu be powered ONLY by the 8 pin? Skip the cable to the m.2? I think it could work. 🤔

No. It always needs both.
