125 Watt Power Supply for Akitio Thunder2

Recommended Posts

No need to worry about the wattage. The system will provide as much as needed. Most important is a stable 12V rail and enough amps for loads. But that PSU is well suited for your setup.

 

Using the HDMI of the MacMini results in the Optimus mode, which will perform slower than connecting the monitor directly to the eGPUs I/O.

Ahh I see, so monitor directly to card and the reason monitor and cpu connect is because of thunderbolt cable connection. 

By the way, I have to boot with the hdmi in the Mac mini or I can't see the screen, once booted, then I can make the switch. 

Its seems to me that the graphics card would be faster if it only had to handle processing the current game I'm running while the internal gpu (no matter how weak) works on processing everything else. Meaning I'm surprised it's faster plugging it directly into the  monitor.

Yes, to have a boot screen you would have to use a GPU that is flashed with a Mac BIOS. But the isn't worth the hassle.

Also, would games run faster or smoother if I directly connected my display's HDMI cable into the graphics card rather than the back of the mac mini? I tried it and it worked but I couldn't tell if it was faster because there are a lot of variables going on that I'm trying to narrow down.

Thanks again! :)

 

It might work faster if you connect to the GPU itself rather than to the host. It reduces the need to send data back over the Thunderbolt cable. Not sure how much of an actual improvement you will see, though. But since it is a Mac Mini (and not, say a laptop where you want to use the internal screen) you lose nothing by connecting the screen to the eGPU directly.

Just the boot screen and by that the boot selection menu. ;)

That is actually a pretty good point I did not think of :)

Hey is there a way to hide all of these cables or like, just cut them off of the EVGA 400 watt psu? I'm only using the one modified barrel plug cord and there's like 100 other cables coming out. I'll never have a use for any of the other ones as I won't be building a pc ever. I only paid $10 for the psu so I really wouldn't mind just severing them if possible haha. I just don't want to fuck anything up. Thanks again!

Hiding the cables is kind of a non issue NOW. It seems like my card is crashing wayy more than it ever did with the other 60watt power supply...i was playing rainbow 6 siege a lot today, and couldn't really play for more than a few minutes at a time without having the card crash. I finally downloaded an app to monitor my cpu and gpu power etc, does this look right to you? (Note the column all the way to the right is the highest, the middle is the minimum and the left is the current) keep in mind I'm not running crazy settings within the game, everything is pretty much at medium and i'm getting 50-65fps at these settings too. I know that the cpu temperature does seem hot, but it's a mac mini and they run super hot, the doesn't even throttle until it reaches 221(f)/105(c) degrees believe it or not. So it's not the cpu getting too hot. Anyways, if you could take a look at the chart and give me your feedback I'd appreciate it.

Thank you!

Which 400W PSU is it? If you cut of cables, make sure they are isolated propperly so they can't short your circuit.

@Dschijn My gpu hasn't been stable since I switched to this evga 400watt psu. when I run hw monitor pro oit constantly says that my gpu voltage is .962 and hasn't changed. Even after flashing my bios so the card will read 65.5 watts. Is there a reason that you you can think of why my gpu would only be a consistent .962volts and never change whatsoever? You can see the table that i posed above...

 

Thanks!

No idea. Better ask in a hardware forum, where they might know the power behaviour of the 750Ti.

      i want to ask two favours and a question from this community ..
       
      1.) Can someone mod my 940 mx to increase the target temperature and allow higher overclocking than 135hzband voltage control
       
      2.) Allowing my i5 7200U to be undervolted to reduce overall heat 
       
      The question : I repasted my gpu and cpu cleaned it thoroughly, made sure twice everything is connected properly, use a cooling pad and yet the upper portion of my chasis above f1-f12 keys is so hot that i can roast peanuts on it. 
       
      (if i left out any info or missed something please reply i would really love to have a page that has everything for people who have this laptop specifically for light gaming.)

      Hi,
       
      I've recently got my hands on an M17x R4 Alienware Laptop from 2013 which I love. I've replaced the screen, keyboard, RAM, and hard drive to make it into a fully modern laptop. However, I'm currently waiting on a replacement for the 680m GPU with a 980m from ebay. My question for you all is, do I need to do anything with the BIOS to make this 980m work? Is there a way to prevent the laptop from using Intel HD Graphics with Optimus? I think the Intel HD Graphics on this laptop are currently broken as I see static-looking dots flash on the screen. (See image below for example). My theory is that because Intel HD Graphics with Optimus is still in-use while in-game, the dots are being caused by it.
       
      Thanks for any help in advance.

      We've had a stack of recurring questions from with problems getting a mPCIe eGPU working. This includes GPU-Z not reporting no clock details, error 10/43 or even not being detected at all. Overall it's more troublesome getting mPCIe working than say expresscard or Thunderbolt.
       
      Here's some common problems and some troubleshooting steps to correct them.
       
      Getting a black bootup screen, resolving error 10/43 or ACPI_BIOS_ERROR win bootup messages
       
      Here the BIOS doesn't know what to do when it sees an eGPU. So the solution is to not let the BIOS see it. Do that by setting the delays on the eGPU adapter (CTD/PTD - EXP GDC or CLKRUN/PERST# on PE4L/PE4C). Boot with eGPU adapter in the wifi slot into Setup 1.30 or Windows. Is the eGPU detected?
       
      I'll add that should error 43 continue AND you have a NVidia dGPU as well as NVidia eGPU then it's likely because of having the mobile NVidia and desktop NVidia drivers loaded simultaneously. Proceed to uninstall ALL your NVidia drivers, use "DDU" to clean NVidia registry entries and do a 'clean' install of the latest NVidia desktop driver.
       
      mPCIe port that hosted the wifi card disappears when connecting an eGPU in it's place
       
      Use the Setup1.30 PCIe Ports->enable to enable the missing port.
       
      eGPU does not get detected
       
      Overcome mPCIe whitelisting by booting with the wifi card and then hotswapping in the eGPU. That way the BIOS will enable the mPCIe port to work.
       
      1. Boot with wifi card into Windows, sleep system, swap wifi card for mPCIe eGPU adapter and ensure eGPU is powered on, resume system. Do a device manager scan in Windows. Is the eGPU detected?
       
      2. Boot with wifi card into Setup 1.30 *carefully* hotplug the eGPU adapter in place of wifi card. Hit F5 to rescan the PCIe bus. Is the eGPU detected?
       
      If this enables detection then avoid this tedious hotswapping by seeking a unwhitelisted modified BIOS for your system OR test the Setup 1.30's PCI ports->undo_whitesting feature.
       
      eGPU still not detected - set the PSU to be permanently on
       
      The latest EXP GDC and BPlus eGPU adapters try to manage the PSU to only power on after they detect a signal. This can cause a race condition where the eGPU isn't ready to go when the CLKRUN signal is asserted.
       
      Avoid this by jumpering the PSU so it's permanently on rather than being managed. Depending on the PSU you are using refer to the following doco on how to do that:

      http://forum.techinferno.com/enclosures-adapters/9426-220w-dell-da-2-ac-adapter-discussion.html
       
      eGPU still not detected - a non-standard mPCIe implementation by your vendor?
       
      PERST# mPCIe pin 22 may need to be isolated due to a non-standard implementation by your notebook vendor: http://forum.techinferno.com/enclosures-adapters/10812-pe4x-series-understanding-clkreq-perst-delay.html#post142689
       
      eGPU still not detected - faulty hardware?
       
      If you still don't get detection then test the video card and eGPU adapter in another machine to confirm neither is faulty.
       
      NVidia driver stops responding
       
      EXP GDC, PE4H 2.4 and PE4L 1.5 all use a socketted cable and therefore are not true Gen2 compatible device. This error indicates there was transmissions errors.
       
      The solution is either to get a better Gen2-compliant eGPU adapter such as PE4C V3.0 or PE4L 2.1b (both with soldered cable), or downgrade your link from Gen2 to Gen1 using BIOS options or Setup 1.30

      Required items:
      1.) Lenovo u310 (I have a Core i3 - Ivy Bridge, 8GB RAM)
      2.) 65CN99WW unwhitelisted.
      3.) eGPU (I used a EVGA GTX 750 Ti from another computer I had).
      4.) EXP GDC mPCIe Edition adapter (got from eBay - banggood seller).
      5.) ATX power supply (I used a 600W PSU from another computer I had).
      6.) USB wireless.
      7.) External monitor, keyboard, and mouse.
       
      Steps:
      1.) Obtain and install a unwhitelisted BIOS. If you are unable to obtain a unwhitelist BIOS, I think it might be possible to bypass it with Tech Inferno Fan's Setup 1.x (may need confirmation as I haven't used it myself yet.)
      2.) Shutdown computer and remove all USB devices, ethernet cables, power cables, card reader cards.
      3.) Remove mPCIe wireless card and detach antennas.
       
       
      4.) Attach EXP GDC external mPCIe cable to the former wireless slot and screw down.
       
       
      5.) Attach HDMI end of the mPCIe cable adapter to the EXP GDC device.
       
       
      6.) Attach graphics card to the EXP GDC device (I moved my laptop off the desk and onto the side shelf to make room on the desk for the monitor/keyboard/mouse).
       
       
      7.) Using the power cable adapters that came with the EXP GDC device, I hooked in my ATX power supply's 20 pin and CPU 4 pin cables. Then hooked the other end (8 pin) into the EXP GDC device. My EVGA 750 Ti also required that I use an additional PCIe power cable (6 pin) in the top of the card.
       
       
       
       
       
      8.) Then I attached my misc devices (HDMI monitor, USB keyboard/mouse/wireless adapter), and hooked in my PSU and powered it on (below is image of final product, also moved HDMI cable out of the way).
       

       
      9.) Power on your computer and let it install the standard VGA drivers and then install your drivers (I didn't have to go in the BIOS for any graphics settings, which it doesn't have anyways, nor did I have to disable iGPU in Device Manager before the card was added).
       
      Extra Info:
      I found that most games will play on med settings with about 45 FPS with this particular card.
      BDO: Upscale on - Anti Aliasing on - SSAO off - med settings.
      Skyrim: Med-High settings.
      Fallout 4: Med settings.

      Hello guys so i bought a used alienware m17x r3 with hd 6870m on it, so when i was trying to boot well it goes to the windows 7 loading screen that says starting windows after that the screen turns white and goes to bsod saying atikmpag.sys
       
      also i attempt to switch my integrated gpu to my discrete card ( hd6870m)  and i wont switch at all 
       
      Responses are highly appreciated 
      Thank you in advance
