920xm + k5000m < 150W ?

Hi guys,

I`m thinking to upgrade my "space friend", currently i`m riding a 670mx, which unfortunately has only 1,5Gb of ram. And there is an opportunity for me to upgrade the video card to a Quadro K5000m which has a delightful 4Gb of ram. The primary use of my "space friend" is work, 3D rendering (on the video card) that`s why the quantity of vram is important to me.

Let` be clear i`m not overclocking. Will my 150W power adaptor work or I need to change it too ?

 

It will work fine but it may throttle a bit under load. Hard to say. If it's not going to be used for gaming it may be no problem at all

 

No gaming (99% of the time), but 100% load on video card for couple of hours at a time while rendering (no cpu load tho)...

Probably I should change the power adapter too but the weight and the hiccup with the battery not charging is holding me back.

Assuming I need to change the power brick too... which one go you guys recommend.. the 210W or the 240W? I`m discarding the 330W variant because I`m pretty sure is overkill.

 

No it won't throttle. It is basically a slightly downclocked 680M with even slower clocked vram. 150W will more than suffice even if you did OC which you ought to as it would help productivity. Stock clocks is 706mhz. You could easily set it to 900mhz without touching voltage and your temps and power consumption would remain largely the same.

 

Thank you guys.

I got the card, the hardware installation was a breeze, the (geforce) drivers from NVIDIA website worked without any modifications and there seems to be no throttling while full load while rendering (so the 150W powerbrick seems to handle it). The idle temp is ~45 celcius and the full load around 65 without any additional cooling.
