Bantam eGPU Enclosure (Enclosure & Assembly Screws)

READ THE DESCRIPTION CAREFULLY BEFORE MAKING YOUR PREORDER!
NEW!: THE BANTAM V2 & BANTAM LONG V2 SUPPORT BOTH OCULINK OR THUNDERBOLT ELECTRONICS NOW!

I believe the CButtersTech Bantam eGPU Enclosure is the smallest eGPU enclosure in the world that supports NVIDIA GPUs giving the most performance per volume in an ultra portable and compact size, outperforming all other recent mini eGPUs that use a RX 7600M Xt (mobile gpu). It's also the only mini egpu that can get you NVIDIA DLSS and Frame Generation.

Choose Bantam or Bantam Long

• The Bantam suports NVIDIA Workstation cards, giving you professional performance on the go.
• The Bantam long supports provides extreme value; adding your own RTX 4060 LP GPU gets you an NVIDIA eGPU solution for a bill of materials around ~$500!

Features:
-Thunderbolt4 (USB4) or Oculink eGPU
-85W Power Delivery Support (USB4)
-Requires LENOVO Thin Tip AC Adapter (options available at checkout)
-Built from durable High Temperature TPU

Q&A

Q: What sort of performance can I expect?
A: It will depend on which GPU you put in the enclosure, but with my own RTX 4000 SFF, and using Surface Pro 10 I have scored a 10755 GPU score in Timespy, 13508 in FFXV benchmark (1080P Standard) far surpassing even the GPD G1 egpu.

Q: What is this Bantam Casing made of?
A: While the casing IS 3D Printed, it is not printed from your common PLA 3D Print Material which would have a potential of melting. The Bantam is dual material printed using TPU and Carbon Fiber PETG. TPU has a softening point of 158C which is a temperature well beyond what the eGPU circuitry will reach. (I.e. It will not melt.)

Q: What GPU can I use with the Bantam?
A: The bantam is custom made to fit a single style of NVIDIA workstation card. Only Nvidia SFF style Cards (that usually operate at 70W) may be used, such as the RTX 4000 Ada Generation SFF 20GB, The RTX 2000 Ada Generation SFF 16GB, The RTX A2000 12GB or other cards that exist in this exact size / shape. If you purchase the "Bantam Long" parts, it will fit a Gigabyte 4060 LP.

Q: Can I power my notebook at the same time?
A: Yes the Batam has 85W Power Delivery built in on one of the two Thunderbolt USB-C ports, If you use the other USB-C Thunderbolt Port you should power your device with it's own Charger.

Q: What devices have you tested.
A: So far I've only tested on a Surface Pro 10, Legion Go, ROG Ally X and the Minisforum V3 Tablet; but I have high expectations it should work on any device that supports Thunderbolt4.

Q: Is there any coil whine?
A: This eGPU is very quiet; having no fans, which makes it mostly as quiet as your GPU you put in it alone, however there is a small amount of coil whine detectable.

Q: What size AC adapter do you recommend?
A: The AC adapter must be a thinkpad style thin plug. If you plan to power both your notebook (up to 85W) power delivery and your GPU (70W) I'd recommend a 170W AC adapter. If you plan on only powering the Gigabyte 4060 LP GPU, You need to use a 230W adapter or it would not initialize.

Q:I see you now have a V2 version. What is the difference?
A: Creating the V2 was necessary because the TH3P4GAN V2 and OCUP3GAN electronics boards switch to a newer PCIE plastic piece which pushed the GPU 5mm further away from the board, a revision was necessary to both support old and new electronics boards, new screw hole positions were also added to allow compatibility for an Oculink version of the Bantam  as well.
