![]() ![]() Part No: ECHO-EXP3FD Echo Express III-D Desktop Thunderbolt 2 Expansion Chassis for PCIe Cards(1)ĭimensions: (WxDxH) 3.8 x 16 x 10.2 in. Price? (inc Thunderbolt cable) : US$979 bhphotovideo-US | 898€ | 899€ Four workarounds can get around that power limitation (1) use a splitter to *safely* access at least another 75W as demonstrated at though it's suggest here that the III-D 6P PCIe connector cabling could provide the full extra 150W, (2) use an external PSU to supply more power as at (3) use EVGA Power Boost to draw an additional 75W from each of the 2 unused slots (max 150W) as discussed in the spoiler or (4) mod the PSU with additional PCIe connectors crimped onto the ring terminals as shown at. NOTE: This enclosure can host a dual-width and full length x16 video card but has it's 300W PSU limited by wiring to only supply 150W. ![]() Using these adapters along with a Sonnet III-D would give a full plug-and-play Thunderbolt eGPU implementation with up to 300W power. The EVGA powerboost product has a female molex end, so would need a gender converter + molex-to-6P (75W) or molex-to-8P (150W) adapter. You'd need 1圎VGA powerboost product to gain an additional 75W 6P connector or 2圎VGA powerboost products to gain access to an additional 150W 8P connector. In the case of the Sonnet III-D, it can be used to draw power from either of the extra 2 unused PCIe slot instead. Prices for this adapter vary from US$10 to US$15. EVGA - Products - EVGA Power Boost - 100-MB-PB01-BR. The EVGA power boost product is designed to draw power from a PSU to a gain systemboard slot stability. So how can you get an additional 6P (75W) or 8P (150W) PCIe power connector without resorting to any warranty-voiding modification or needing to use an external PSU? That then means only 150W (max) can be provided to a single PCIe card. Sonnet budgetting up to 75W per PCIe slot. My solution to this would be external power supply which wouldn't be a problem installing, however this would result in a big thing laying next to the computer etc.INFO: Using EVGA Powerboost product to draw 75W each from the Sonnet III-D's extra 2 unused PCIe slotsĪs you know, the III-D has a 300W rated PSU, has 3 PCIe slots but only comes with a single extra 75w 6P PCIe connector. Power: Apple says that the Mac Pro I have has " 300W combined maximum for all PCI Express slots" and the 295X2 requires 500W. are these solutions just very bad or is it actually possible? The AMD R9 295X2 is very powerful and requires a lot of power, cooling, and space, which is hard to achieve in my Mac Pro, I have done a lot of research and found solutions for these however. I thought of installing an AMD R9 295X2 into my Mac Pro, is this a really impossible and horrible idea? I have a 6 core Mac Pro, the 5.1 model I think, or Mid 2012 with pretty much bad graphics for my purposes (ATI HD5770). ![]()
