Power supply for lenovo Legion T730 (RTX2080 + i9 9900K)

2019-01-30, 18:03 PM

I just bought the  T730 but realized that it only comes with 500W power supply. I'm not an expert on this but I feel it is not sufficient to power both RTX2080 and i9, but I also feel Lenovo should not make a mistake like this. Do I need to get a more capable power supply? How many watts do I need? Also if I swap the PSU, will my warranty be void? Thanks!

Hello,

No idea if it voids the warranty, but otherwise you're absolutely right. Investing in a sufficient power supply is a must, i would suggest anything above 650w. 

Surely, if you would like to upgrade some hardware in the future, the bigger the power supply the better space you have for future upgrades.

Good luck

i also have the same question.. I'm about to upgrade from 500W to 650W+ PSU since my LEnovo T730 with the same specs is suffering a Power Throttling. is there an issue if i upgrade to 650W. Will the MObo able to handle higher PSU.

I don't think it voids the warranty, but the warranty is only on original parts; it likely wouldn't be good if your new PSU fried your GPU as Lenovo would not replace it. That's the risk you would take though and I would say you are less likely to do that by getting a decent PSU from a known supplier and at least an efficiency rating of Gold.

 

Also, in regards to "frying the motherboard", that's not exactly how it works. The power that is drawn from the PSU at 650W isn't always 650W, it just depends on what your individual components are drawing. So, your CPU only takes what it needs, your GPU etc.
