Morning all,

I'm going from a 3060ti founders edition to an EVGA FTW3 3090.

The 3060ti uses the proprietary PSU adaptor from the 8-pin PSU cable. The 3090 uses 3 8-pin connections. My PSU has "GPU1" and "GPU2", but this only gives me two out of the three necessary.

Would one of these work to give me the three? https://www.geewiz.co.za/cables-ada...mocab12-8-pin-female-to-2-x-6-2-pin-male.html

If so, I am worried about the length of that cable.

Any help would be appreciated. Thanks so much.

What power supply is it? Are you sure it has enough juice for the new card?
 
I was going to push my luck with my EVGA 650W.

I read that it shouldn't be an issue, but I think I will have to grudge buy a new PSU.
First you'd push your luck with it being 650, then you'd push it even further by splitting the plug.
If you didn't want a heater, you'd probably get one soon enough with that setup. Rather get a 800w up, as the 3090 has a recommend PSU that could deliver 650w, that would be just for the GPU

I don't know about pushing luck. That is taking a moerse chance even if the psu is highly rated and the rest of the system rather efficient.
 
I deserve this.

Thanks all.

This is a 3090 I sent to MSI Taiwan for a deep analysis on the root cause of failure. Two months later the report was back. It was a massive over-voltage - turns out the transient loads are so fast that the 650w PSU couldn't trigger OCP quickly enough.

I honestly wouldn't go below an 850w (preferably higher), high quality PSU for a 3090. Maybe something like this:


For those having a panic over the GBT recommendation, the exploding PSU issue only affected lower watter, lower end, older units.

If that's still not up your tree, there are plenty of alternatives from Corsair, Asus, etc that will do the job without you ending up with a paperweight.

 
Please donr split , just buy new psu

Yes I used the split cable that came from the psu and had constant restarts and crashing each 8 pin needs a dedicated cable to the psu so for two 8 pin gpus
“GPU 1” and “GPU 2 “ should be occupied on the psu
 

I really like this price point however I am worried about the infamous Gigabyte Coil whine.

It's a new range with little to nothing in common with the older models.

There are, of course, alternatives in the 1kw range:

General question - If your ram is hitting 75% during gameplay, would you upgrade from 16gb -> 32gb? Not necessarily needed but curious what you guys would do. (higher frequency as well).

The alternatives are way more expensive without the coil whine but then I guess you pay for the ATX 3.0 certification.

I am in two minds on this decision.

Anyone with the Gigabyte GP-Uxxx PSU have some feedback?

They are indeed quite a bit more which is why I didn't recommend them specifically. That said, I don't believe there's any known coil whine issue with them. The disti brought in 1k units and has just over 500 left, so they've had fairly rapid adoption and I don't know of anyone complaining.

Lemme ask Gigabyte quickly.

If that PSU were a problem child, I'm certain that customers would be complaining to retailers would be complaining to the disti whose PM would complain to Gigabyte, so I'm leaning towards it not having issues of past.
