(1080P Standard). The RTX 5060 and OCUP4GAN combination has scored 13487 in timespy and 15,300 in FFXV Benchmark.

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.)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What GPU can I use with the Bantam?\u003c\/strong\u003e\u003cbr\u003eA: 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 PRO 4000 SFF Blackwell, 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. \u003cbr\u003e\u003cbr\u003eIf you purchase the \"Bantam Long\" parts, it will fit a Gigabyte 4060 LP or Gigabyte 5060 LP or even the NVIDIA SFF workstation cards, but it will have wasted space.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I power my notebook at the same time?\u003c\/strong\u003e\u003cbr\u003eA: Yes if your power circuitry you end up choosing supports it. For instance the TH3P4GAN has 85W Power Delivery built in on one of the two Thunderbolt USB-C ports; the TH5P4GAN has 100W Power Delivery. If you use the other USB-C Thunderbolt Port you should power your device with it's own Charger.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What devices have you tested.\u003c\/strong\u003e\u003cbr\u003eA: So far I've only tested on a Surface Pro 10, 11 (Intel), Legion Go, ROG Ally X and the Minisforum V3 Tablet; but I have high expectations it should work on any device that supports Thunderbolt4.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is there any coil whine?\u003c\/strong\u003e\u003cbr\u003eA: This eGPU is very quiet; some models 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What size AC adapter do you recommend?\u003c\/strong\u003e\u003cbr\u003eA: The AC adapter must be matched to the circuitry and GPU combo you end up buying. (TH3P4GAN, OCUP3GAN, etc...) I prefer buying the circuitry with 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 or 5060 LP GPU, You need to use a 230W adapter or it will not initialize. I  have had success with power tuning a 5060 GPU and using it with a 170W adapter, but this isn't recommended necessarily.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ:I see you now have a V2 version. What is the difference?\u003c\/strong\u003e\u003cbr\u003eA: 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.
