Can I Install in PS Capacitors With A Slightly Different Rating?

Recently, my monitor died. It refused to turn on, and after some research, I traced the problem to capacitors in the power supply. I bought a replacement kit on eBay, and installed most of it, and realized that it didn't come with all the right capacitors. One of the capacitors that I need to replace is rated at 220uF-25V, yet I recieved capacitors that are rated at 220uF-35V. Now my question is, can I install the 220uF-35V caps in place of the 220uF-25V's, or will I have to drive to RadioShack in a foot of snow and buy the right ones for 10X the price? The seller will not accept items that are opened, and since I installed about 1/2 of them, I don't think that will help either.
