labonator Posted September 25, 2013 Share Posted September 25, 2013 The 580m / 675m ( aka the same cards ) Have a TDP from 100watt each . Deppens on what line out of the first gen you have is it a i7 or i5 ? normaly people with a older spec laptop put an extreme cpu in it like a 920xm or higher up .So i can go along with some new graphics card, i dont know if 150 watts is enough for a first gen cpu ( since they take more power ) with a new gpu that consumes a fat 100watt. Which gpu do you have currently in it ? Quote Link to comment Share on other sites More sharing options...

Which gpu do you have currently in it ?its i5 cpu - 35Wcurrently HD5870m - 50Wstock acad was 120wI got 675m working fine in msi 1761 using 150w acad without issue, there was i7 2630qm = 45w.I mean the acad isnt problem at all, I can even plug in 300W acad, I'm worried about motherboard or if i5 is enough for it. I've heard somebody got hd7970m working in that machine, which is as well 100w gpu. - not sure what was the cpu in his machine.It's just I dont want to upgrade cpu to 920xm if I dont have to... this laptop is a present for a friend of mine, and I got some spare GPUs, trying to upgrade it as good as possible at very low cost. And I dont want to fry something. Quote Link to comment Share on other sites More sharing options...

And I dont want to fry something.The cards should work just fine, but I don't think the heatsink will work without modifications. Quote Link to comment Share on other sites More sharing options...
Bugii Posted September 26, 2013 Author Share Posted September 26, 2013 I got genuine gtx580m heatsink from my 1761 - that one should fit well I think."mechanical" part of installation looks ok, I was just worried about motherboard and CPU.I'll try it as soon as I got some time.Thank you guys.

Bugii Posted October 7, 2013 Author Share Posted October 7, 2013 just an FYI if anyone interested..it works, however the i5 460m seems to be bottleneck for this gpu.mostly around 70-90% gpu usage, framerates are okay-ish, still very good upgrade though...it could be better...I was surprised by the temperatures - maybe it's because of the usage - 43C idle, 75C load (Same card in msi 1761 i7/2630qm was 45C - 86C) Quote Link to comment Share on other sites More sharing options...
@t0mX Posted June 19, 2015 Share Posted June 19, 2015 Sorry to unearth this topic, a friend asked me to find out if you had done any hardmod on heatsink (original) or just used the 1761 heatsink with no mod? Quote Link to comment Share on other sites More sharing options...
Bloetschkopf Posted July 5, 2015 Share Posted July 5, 2015 The better Way to Upgrade the GPU in GX660 is to use a GTX 670MX or GTX 675MX.With OC Vbios You will get 5000 to 6000 Points in 3Dmark11.I tried both Cards in a GT660 ,i think a GTX 680M will also work in this Barebone.All Cards are Kepler GK104.
