No you plug in the 4pin 12v connector, commonly called CPU power. Its the plug that goes somewhere between the CPU socket and the the top back corner of the motherboard, the one that's hard to reach a lot of the time in a tower . - - - Updated - - - Same chipset as my Precision M4400, so yes it will work but we are on a older PCIe bus so have less bandwidth to the card. Also if your running 4gb of ram be prepared for a Code 12 on the new card and having to either drop 1gb of ram or doing a DSDT override. Also I would recommend getting a AMD card, since our discrete nvidia gpus are based on the old architecture we no longer get driver updates so the newest driver your Nvidia eGPU card can have is the newest driver that will work for the discrete GPU, which is already a few months old.

Thanks Nando for the reply, I will have to think about the PE4H. The M4400 is my secondary system, my main system is a Toshiba S55-A5188 with a i7 4700mq and 12gb of DDR3 and HD 4600 graphics (which is better then the precision 1700m by a bit). I just decided to give this a go to see if I could get some games to run that the Toshiba and precisions graphics couldn't handle. I saw that banggood has the Mini PCIe cable for sale for $20 I might get that and try it in the Toshiba, any ideas what the system would be running? I would assume at least gen 2 PCIe? Also is the ac adapter that you can use with the Beast the Dell DA-2 220 watt adapter?

I know it's a bit of a older system but I was wondering if there's anything I can do to improve the eGPU performance. Imgur a few games in my testing have improved performance over the integrated, so I am not fully trusting the benchmark. I am assuming the express card only being PCIe 1.1 is bottlenecking the 750ti just wondering if there is anything I can do to improve that? Specs. Dell Precision M4400 Core 2 Extreme QX9300 @ 2.55 (stock speed undervolted) 3gb of ram DDR2 800 (if I run 4gb I get Code 12) discrete GPU Quadro FX 1700m eGPU is the EXP Beast over express card and the card is a GTX 750ti 2gb, PSU is a OCZ Fatality 550 watt

Thanks for all the info on this thread and the linked, Wikis and guides. My EXP Beast arrived yesterday, i bought it to see if I could liven up my old Precision M4400 so with this hopefully a 750ti and it's new QX 9300 it would stay pretty potent for another year or two since my newer laptop is more limited gpu wise. After wresting around with it I got the install but got the Code 12 when I was first testing with a GT 430, so dropped from 4gb to 3gb and walla it was working, was getting some strane issues, If I ran the GT 430 as the main and GPU and external display only I would lose either my Wifi or my audio. Luckily after getting the GTX 750ti installed that issue went away and its been relatively smooth sailing with that card other then a weird keyboard backlighting issue which i had to mess around with. I was worried after runnning 3dmark06 and the 750 ti barely outscored my discrete Quadro 1700m. I fired up The Crew, a game my 1700m can't play on lowest above 25FPS, and the game was running in 1080p at 30-60FPS so that was successful, BF4 was a disaster ( lots of FPS stutter and Frame lag) and GTA V was running a lot better until i tried to move then the FPS dropped like mad. I know to get the 4gb and the card I have to prob do the DSDT override but that is a bit over my head atm and the current OS is not staying because it has been acting weird for the last 5 months even though it says it should be fine. Again thanks for the thread I will be reading more and might have some questions here in a few days. [h=1][/h]
