So ive been reading some in the "DIY eGPU experiences [version 2.0]" thread. And i belive i have came to the point where i should order the equipment needed.
Im trying to keep it low budget.
Now i could use some input before i go ahead and order the parts needed.
Specs Lenovo B590
CPU: i5-3230m
GPU:Intel HD4000 and Nvidia GT 720m PCI-E 2.0
Ram:8gb (2x4gb)
External Monitor:22"Belinea
Win 8.1 64bit UEFI
I dont have slotcard so im forced to use the m-PCIe, where my current Wlan module is located.
Hence im forced to use:
PE4L V2.1b + PM3N +60cm PE4L-PM060A + SWEX, For GEN.2 PCI-E
Correct?
Regarding the GPU, im looking at something between GTX 4XX-GTX 5XX. Depending on what i can find in the 2nd hand market. Remember im trying to keep it low budget, and which ever i get of those card it will perform atleast twice as good as my GT 720m, correct ?
Regarding the PSU im pretty clueless.
I have an older PSU unit that used to be in a "HP Pavilion p6770sc", i belive its 300w, but im not sure about it having the 6-pin connector required to run some of the GPU:s. (HP machine had a HD6570 GPU). As ive understand it there are some of the GTX serie cards that doesnt need the 6-pin connector, correct? (The naming scheme of the cards are really confusing imo ).
Regarding the box to keep all the junk in, i will take it as it comes and probaly improvise, this is a secondary issue.
And then there is the question to get all of it to work, ive looked thru the lists and i havent found anyone implenting the diy eGPU solution to a Lenovo B590. Configuring everything software wise seems a bit complicated, and there seems to numerous errors that could occur. I guess ill come to that part later once ive ordered all the parts and trying to set it up.
Hoping for input from someone more experienced regarding all this.
Edit; Done some more research and it seems i gotta invest in a new PSU with 6-pin connector(s) aswell.
Edit2; I have found a Geforce GTX 550 Ti for a decent price. Would this be a decent card? It requires one 6-pin connection.
Edit3; Also found a Geforce 480 gtx for the same price, seems to be slightly better in terms of performance but alot more power consuming. (heat shouldnt be an issue due it being external).
Edit4: I found a MSI Gtx 650, its pci-e 3.0 version, are these cards backwards compatible with 2.0 and my future eGPU setup?
I had some issues with this before, namely the HP machine mentioned above couldnt run a 3.0 card, due the mb only supported 2.0-2.1, and it wasnt backwards compatible.
Edit5; More research done.. Would it possible to use the psu mentioned above (that most probaly doesnt have any 6-pin connector, i dont have the psu in my reach atm so i cant tell for sure), with a converter named something like "4 Pin PSU to PCI-E Power Supply Converter cable" ?
