I have a Lenovo h430. It's a really cheap computer bought it for $250. It has Lenovo mahobay motherboard. I have. A600w psu, question is does my motherboard have a pcie x-16 slot? If so will this support a radeon 7850?
According to the manual for the H430 is has 1 PCIe 16x slot. Should be the slot closest to the CPU out of the 4 slots (PCI on bottom, PCIex1, PCIex1, then PCIe-x16.
The 7850 requires 125w max so you're pSU should also work.
Please don't continue to open duplicate/near duplicate threads, again Yes, you have one, and for a 7850 you will need a decent 480 to 500 watt PSU, look for at least 21 AMPs on the 12 volt, might look at:
