    Lightbulb HP 2740p + MSI GTX670 overclocked version

    Hi! I'm a lurker who recently purchased some parts to start building it rather than reading stuff for hours and on. I've read ver 2.0 sticky as well as Agent 9's setup with 2730p laptop which is very similar. The information seems just so fast 900 + pages of Forum posts.... + archived 1000+ posts. I think I'll do much faster if I get some precise pin pointed answers regarding specific models to narrow the choice.

    So here's some specs.

    I have HP Elitebook 2740p
    I switched motherboard to corei7 620M 2.66GHz
    4GB RAM, going to upgrade to 8GB (will pci be ok or something?)
    Has expresscard slot just like any hp Elitebook series.

    I bought this thing off kijiji which is some Canadian site
    Apparently it's a PE4L v2.1b



    I bought GTX 670 MSI OC version
    you can see pictures and some specs here
    MSI N670GTX-PM2D2GD5/OC GeForce GTX 670 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card - Newegg.com

    I'm wondering though, will this card fit onto the picture shown above? It seems like the connector above seems too short to be able to connect the gpu on there.


    Another question is, how do I know what type of PSU do I need? It doesn't say on the box or in the manual what the wattage or Voltage is.

    Thanks for reading such a noob post... I was reading and reading and reading and I just kind of still had no idea what PE4H PE4L and what they were, I know PCIe is but not sure what those mean... Hopefully everything somehow comes together in the end...

    Going to play APB when I finish the set up

    Oh also, I want to use an external screen for this, Don't want to go through the hassle of reducing my performance. Do I need an HDMI cable for this? Or will normal screen not enough. I think I'd need to buy another monitor if it needs HDMI. Thanks.

    Hi, I'm afraid you bought the wrong video card. you should by a shorter interface version which is PCI Express 1x.

    "The PE4L is designed for Notebook PCs that converts PCI Express 1X add-on Card to ExpressCard or mPCIe connecter or PCI Express slot."

    Something like: "http://www.newegg.com/Product/Product.aspx?Item=N82E16814161398"

    by the way, is there more product on Kijiji, i'm in canada too.


    Nando>> above is incorrect, see message below.

    Please disregard saga25152's message above as is incorrect.

    A PE4L 2.1 uses an open ended x1 slot and so can accept a x1, x4 or x16 length card. There are plenty of examples of PE4L 2.1 units used in such a capacity. Eg:

    12.5" Dell E6230 + GTX660@x1.2Opt/HD7870@x1.2 (PE4L-EC060A 2.1b)

    It's the lowest cost Gen2-capable expresscard/mPCIe DIY eGPUsolution that's completely functional. While the 2740P doesn't need Gen2 capability it's certainly good to have if you were to upgrade to say a 2760P. The pricier PE4H 3.2 uses a x16 slot and has an enclosure option.

    MSI GTX670 has a 170W TDP rating. You need at least a 12V/15A PSU on the first rail. Better would be to aim for a 12V/18A one to give some overhead and with some higher quality components.

    Which is better? E6440 is 2.5+ times better at 70% the cost of the MBP making it 3.5+ times better value => MBP had to go

    wow THANK you!!!!! I couldn't ask for a better reply from nando himself

    So I can get any PSU without having to worry about overpowering?

    I would think that there's some regulator in place in case of overpowering maybe?

    Thanks for the link, I'll take a look at it today!

    I'll post results on how it goes! Thanks for everything HAHA

    Exclamation

    OK I got everything together except the PSU.

    So here's a very few questions I'm not too sure about.

    re01.jpg
    1. What Voltage, Ampage, and wattage do I need for my PSU? Will any old computer PSU make do? Does it have some ground that can leak excessive wattage and voltage? That blue connector is supposed to connect to a PSU I heard.

    2. What do I do with these wires????? Do I need to cut the GPU wires and make mods myself to fit to the power connector on the PCIe adapter?
    Here's the picture. re02.jpgre03.jpgre04.jpgre05.jpg

    I'm sorry if this is a basic knowledge but I was never taught how to connect where to where and I don't want to connect wires to wrong place and possibly short or blow up the gpu somehow.

    I think there's some numbering convention for the 24 pin connector and what those 3 pins from the GPU mean...

    So in conclusion: Need to know what PSU to get or if it's ok to use some random PC's PSU from an old computer
    Also, How do I power the GPU from that 24 pin connector? It doesn't seem like the power connector from the GPU doesn't fit there, perhaps I'm supposed to connect the GPU to PSU directly? Then what's that 24 pin connector for??

    Thaaaanks!!

    Pic 2, those are PCIe 6 pin connectors. You have 2 of them, you're supposed to plug them into the PSU's 6 pin PCIe connector. If you have only 1 PCIe 6 pin connector on the PSU, use the dual molex to PCIe (pic 3 cable) connector to convert it into a second PCI so you get 2 in total.

    Pic 3, power supply main connector - connect it to the power supply.

    Pic 5, I can't see what's there.

    Ok, Thanks for the reply. You know what though, what I'll do is just go out and buy like a random 400~500w PSU and see if they connect.

    It seems like I need to actually do things instead of keep asking questions this is bullpoop, not even advancing anywhere.
