Hello guys i have laptop that i added external GPU to it using adapter, PSU and some few softwares and tweaks to make it work.. means that the PSU is only powering the gpu, the other system of the laptop like cpu and stuff have it own power from the laptop..
i had AMD 6950. and then upgraded to 960 gtx (which worked perfect), and now upgraded to R9 290, which is high end card, but i thought my Seasonic S12II 430W is enough for that.. (even some of u guys told me that its enoguh http://www.tomshardware.com/answers/id-3478147/430w-970-gtx.html)
i installed drivers, i plug 8 pin and 6 pin to the card... and also the extra power cable to the adapter..
when i launch a game like PUBG or Rust, it crashed after few seconds or few mints.. even now on desktop usage i sometimes have freezing for 2 seconds.. this means that the psu isnt strong enough? but how? how can it be? its a modern 430W seasonic PSU that suppose to power only this gpu..
is it possible that the gpu have problems? its a used card but its hard for me to belive that the guy sold me a broken card..

Well the 290 can use a max of 375w. What are it's temps? Also you could've just been sold a slightly broken card that still would boot into windows but actually breaks when under load. I've had a couple of used cards that were brought back from the dead with the oven trick and sold to me then. After about a month they just died.

Well unless you have someone to test the card for you I can't really help you further since it hangs. It could just be that it doesn't agree with the dock or it could be a broken card.

r u saying that the option of the "psu isnt strong enough" isnt option? like if i will upgrade to a 600w psu it wont do a change?
i dont really has a dekstop to check it so, im thinking about buying psu but, what do u say about 980gtx? im going to sell this card and get 980gtx and im wondering if the 980 is a high end card like this? or maybe its more like the 960gtx which worked perfect in my setup.. (and then i will not have to upgrade psu..)

The 980 is stronger and uses less power. However before you go with the 980 I would try out a new psu since I did some searching on the topic and found out that the seasonic cannot handle the load. It does output 430w but this is combining everything it can't deliver the 375w the card needs to the card alone according to my findings (got it from some forum about mining).

A few things to consider:
The R2xx series was very popular for bitcoin mining, meaning it could be a faulty card.
Even if the GPU is getting enough power, there could be other issues (such as the interface itself) preventing full performance.
The specs of the laptop matter too, if the processor is weak adding in a stronger graphics card can lower performance in CPU bound games (such as the games listed)
Insufficient PSU wattage would not cause games to crash.

My recommendation:
Stop trying to fix a problem that you made for yourself.
If you want real performance, get a proper PC.

i have a very good deal to upgrade to 980 in almost zero bucks on friday.. so buying a new psu is my last option cause it will be a waste of money.. im going to upgrade to 980 in this way or another on Friday so i think first i will test the 980 and only then decide if buying psu..




"Insufficient PSU wattage would not cause games to crash." - FALSE, big flase for that..
its very common to crash the game cause of gpu not getting enough power.. u can check it everywhere online..
i dont have money to get proper pc thank you for ur advice..

bro srsly why u talk if u dont know? i had 0 problems in my laptop. i had 70 fps in csgo and when i pluged the eGPU to my system i had 200 fps.. in rocket leauge i went from 10 fps to 90.. the performance are impressive and these days i started playing PUBG and i had a great deal upgrading to r9 290 and even earn moeny on that, so i didnt waste money on this.. and on friday im going to upgrade to 980gtx and waste about 10 bucks for that.. i dont want to buy pc right now cause my laptop is more then okay.. its not a temporary fix, im using this rn for more then half year and its working gr8..
the problem now is probably or because the psu isnt strong enoguh, or the gpu is broken. there is nothing to do with the laptop thing, i would have this problem in a dekstop pc also so please check what u r saying before u send it..
im here trying to fix a problem, no offence but i dont need ur advice..
