No idea where to buy a graphics card at

I am not too sure which cards do not require the upgraded power supply. The only one I know for sure would be the GTX 460m. My personal thought on upgrading is if you are gonna do it, get something top of the line, which I believe most will require the 240 watt power supply. Hell they are not that expensive to buy. I definitely recommend getting the GTX 680m though if you have the money. I am very happy with my decision. I would also recommend changing out the thermal pads as well. I did not because I didn't realize it at the time, but the ones from my GTX 260 m are kinda crappy. I don't think it is a huge issue if you don't, as my card works great with the old ones, but they are inexpensive and if you are in there upgrading might as well get the better pads. I also love the cooling pad that I got as well.

 

Get 240W one as it is cheapest and most powerful before the enormous 330W brick. Then center pin mod it so it can deliver it:s max power output.

 

Center pin mod?

 

Ok. I'm gonna look for the power supply and gtx680. One question though, I cannot find anything called x-bracket in Europe. Any idea how it might be called other than x-bracket?

 

Many come with the x-Bracket, just ask to be sure. You can look on ebay for one, it can be named GPU spreader or GPU heat sink spreader.

 

Here is the X bracket I purchased. They still have more available.

I just want to add a little something the upgraded power is not required but ADVISED, getting a bigger power supply will only help if your 150watt psu is constantly over heating and tripping and thats more likely to happen when overclocking. so even if you install a higher card like the 680m, the 150 psu will still work. it might be better to get the 210watt psu that King of Interns has, im not a big fan of nvidia card in the M15x as they seem to throttle way more than the amd cards, for some reason the cpu and nvidia gpu to get along

 

With a 210W, 230W or 240W PSU you won:t have throttle anymore. Must disable the middle pin though which in turn will not let the PSU charge the battery. Keep the 150W PSU around therefore for this purpose at night for example.

 

My m15x is always connected as it's a desktop replacement, so basically I don't even need to charge battery. I'll grab some bigger PSU, it's cheap compared to other things.

As for the x-bracket, I saw that auction, but the shipping cost is more than the part cost...

I will probably grab this GTX-680M , and unfortunately this one is without bracket.

 

Never heard back from you. How'd it go? Installed and running well?
