Hi,
I accidently stumbled upon diy egpu and I was instantly intrigued. I use several laptops, mostly small ones with igpus.
So I have pulled the trigger and decided to initially make a setup for my thinkpad x220. (hd3000 igpu, sandybridge chipset)
The idea is to make the setup as small and portable as possible, perfomance is of secundary concern.
I do some mild gaming, mostly blizzard games, which will run good on low/mid gpu's.
The components I have selected:
- PE4L 2.1b with express adapter and soldered cable ($58, already ordered and shipped)
- Low profile Zotac GTX650, this card only uses 64w and will be solely powered by the pci lane.(~$100, pending suggestions)
I will decapitate the vga part of the mounting bracket, lowering the height more. Very small and low power.
- Uknown enclosure of own making, as small as possible ofcourse, thinking black aluminium, small perf'd vent holes matching thinkpad look.
- Yet unselected ac power adapter, need some help with this.
About the power adapter, is there a goto proven ac power adapter for the PE4L? The 12v output is somewhat limiting. I have access to a large variety of laptop adapters at work (HP, toshiba, lenovo..etc) but all are in the 15-20v range.
I am hesitant to buy a "universal" adapter or import a "high quality replacement" from china. I think clean power is very important, bad psu is an underestimated cause of errors and issues.
Ideally I want, high efficiency, low ripple NR, proven brand in a small package. I assume a 90w quailty adapter would drive the 75w pci lane well, but more watt is no problem. Price is secunday concern. Ideally no soldering on the wires needed.
I have ofcourse googled but its kind of tricky, the 12v part results in lots of bad hits with car stuff and converters.
Am I going the right way?? Plz advice.
