This is FUD at this stage.
I’ve been running Windows 10 in EFI mode on 3 different cMPs for years and years, with many rebuilds (I work in IT), and have not had a single issue.

I completely agree; I’m in the same position as you, and also work in IT

My Mac Pro though is on a much earlier firmware revision than discussed; the 2017 version when 10.13.0 was released to enable APFS boot support.

Just wondering how the two things correlated, as I was considering getting an RTX 2070 to replace my 1080.

I wonder if the new 1660 has the boot screen as well? It is in the same turing family, but the power draw is only 120W. Can run off the single mini 6 pin.

There’s only one “reference” model on NVIDIA’s website from INNO3D that shows an 8-pin connector and NVIDIA’s name on the board near PCIe.

Design is strikingly similar to a Sapphire Pulse RX 580 8GB.

That is strange as the specs say 120W power yet the connector is 8 pin. Here is another version:

and the price is very affordable.

The GTX 1660 Ti that AnandTech reviewed was *2.75 slots wide! Be careful in your choice. But, this is all speculation as there are no Nvidia drivers, yet. Sigh...

If they go on sale from retailer with gracious return policy, may be able to try in HS but cannot find that INNO3D model available in US.

Size and design on some looks very similar to NITRO+ RX 580 models. Even down to the backplate, blade heatsink below the fans, and even fans themselves. The GTX 1080 FE is a much better design/fit for MP5,1 machines but certainly seems like manufacturers prefer different style on some models now.

The dual fan one's looks like they might cool better, IMO-but also a Powerlink might block the Asus intake on the end port if the pin is setup too close to elbow of the Powerlink. It's hard to tell from the angle of most the photo's I can find. I get it's under-powered and not necessary, but I like CYA-and I like it, so I'm just happy there may be models that are compatible.

Just really, I like the dual fan better-better airflow is always good.

Have you seen the INNO3D model available in the US? Have seen a bunch of 1660 Ti options, but none are the "typical" reference design with the NVIDIA logo on the board near the PCIe connection. The ones with the brand logo on the board have been modified from reference in some fashion. Doubtful we'll see a true Founders Edition version of this GPU.

Yeah, I'm a little confused by this card since it's so closely priced with the RTX 2060, but maybe it's intended for more global markets or something (supposedly China is an emerging gaming market, depending on who you ask). But I did just take a look and there are five unverified GTX 1660 BIOS available for inspection by anyone that knows what they are looking for to see if they might have bootscreen:

Assuming that you have strong case fans.

The blower models have the advantage that they pull air from inside the case, blow it over the heatsinks, and exhaust it outside the back of the system.

The fan models just add heat to the inside of the case, and hope that the case has good enough ventilation that the heat will eventually be pushed outside the case.

As a DIY'er I fashioned an L shaped piece to pressurize the PCIe slot to keep air moving. I should have mentioned that-and my FE uses a blower and it assists. I also have one slot filler removed as a pressure relief though too, as CYA.

EDIT: CYA cooling an NVME on a riser-blowers could def use that airflow also but its always a balancing act.

If the "one slot filler" is a blank PCIe bulkhead on the back, this can be a problem.

You want front to back airflow - bring cool air in the front, blow hot air out the back.

If your case is positively pressurized (inlet fans stronger than outlet fans), then a missing blank will let the exhaust air bypass, resulting in less airflow through the blower card.

If your case is negatively pressurized (outlet fans stronger than inlet fans), then hot air from the back of the machine can be sucked into the case. This will be especially likely if the open slot is above the GPU/CPU/..., since hot air rises.

My servers are designed as positive pressure cases - all of the fans are in the front, and pressurize the case. All airflow is front to back, over the cards and components. Removing a PCIe blank would mean that air goes out the open hole, not over the cards.

"Being a dual-slot card, the NVIDIA GeForce GTX 1650 does not require any additional power connector, its power draw is not exactly known. This device has no display connectivity, as it is not designed to have monitors connected to it."
https://www.techpowerup.com/gpu-specs/geforce-gtx-1650.c3366

Sadface, LOL. Thanks, I didn't see anything over there. Still, even at high-end Kepler performance for only 75w is pretty good. The TechPowerUp says no output-but the first article says it's for gaming? eGPU application on a internal monitor? Maybe mining or more likely I'm missing something, LOL-but it also said no SLI. I'm guessing more advanced compute application if it is truly headless.

They might fit an external application-at a reasonable price for several.

Only Mining cards don't have display connectivity. I guess they are wrong.

Pretty sure there will be a GTX 1650 with display connectivity. Otherwise the GTX 1650 is DOA.

But if it is 75W card then it makes sense . If it is not connected to an output it does not need much power draw.

The outputs do not need much power. E.g. the GTX 750 Ti, which has connectivity, was designed for under 75 Watt.

https://www.geforce.com/hardware/desktop-gpus/geforce-gtx-750-ti/specifications

Not all were the same. Have a Gigabyte GTX750ti that needs a single 6 pin for power. Card worked fine, despite a cracked resistor that only allowed it to link at 8x and 2.5GT in slot 1. Also Dual DVI, and two HDMI which is not standard.

Likely reference cards were to have no power connectors...
