Will this Graphic card work in my system

[heathscliff]

Hi!
I have a HP 6300 PRO SFF with 250 W PSU , i have been looking for a GPU for it for some time now, i found many Low profile GPUs, i was about to buy a R7 250, which i confirmed would work in my PC, but then i found these cards from "YESTON".This GPU requires 300W PSU power consumption is around 45-55W, So my question is will this card "FIT" in my SFF? and will run with that PSU? IF not, can i change PSU in this system? IF so which one i need to use this GPU

To be fair, if you have the budget, I would upgrade your whole system. Anyway never heard of ''Yeston'' plus if it says it needs 300W PUS then it may be safer getting a new PSU too.

Yes i know, i will make a new build after 2 months or something, for now i need to use some card for this PC, Yeston is a chinese company which makes same cards (nvidia/amd with SAME performance or even higher at points with comparatively LOW price and Low power consumption as well) So i was thinking of getting this if it can "Fit" in my case and be used with 250W PSU, but if i need a new PSU, i don`t know which one to get.
