Thinkpads Forum

I bought a used T430 that didn't come with a power supply. This model has discrete graphics, so I assume the OEM power supply is 90W.

I don't have a 90W PSU, but I do have a 135W PSU from my Thinkpad W510. Would it be safe to use this 135W PSU with the T430? This would be temporary as I'll get a 90W PSU and sell the W510 along with the 135W PSU.

Yes. The computer is only going to draw as much current as it needs to satisfy its needs. The higher power PSU simply has a higher maximum current - the voltage is the same.

Thank you.
