number of PCIe lanes required to drive four 4K 60Hz monitors with NVIDIA Quadro P600

[AvatarComputer]

I plan to purchase a NVIDIA Quadro P600 GPU to drive four 4k 60Hz monitors. This GPU has PCIe 3.0 x 16 as its mechanical interface, but how many PCIe lanes it will actually use? My motherboard has a PCIe 3x16 (wired 4) slot, will it be okay?

it doesn't matter, card will always use the same amount of pci lanes

16 lines

Probably 16.

Well if the slot is wired for 4 then it will use 4 lanes

It will use as many electrical pci-e lanes are in the slot.

 

The card should run in x16 physical , x4 electrical.  It will run in x16 physical x8 electrical (for example if you install two cards and the motherboard has two x16 slots that auto-switch to 2x8 when two cards are inserted)

 

There may be some performance drop when running the card in x4 electrical, but depends on what you'll use the card ...  windows , browsing, movies etc won't matter that much, gaming there will be some noticeable (but not very big) effect

If you have a 1X slot that's open at one end, you can put it in that and it will only use 1 lane. Imagine the savings!

Depends on what the slot is wired for. If it's x16 and that's what's available, then it will use all 16 lanes.

Technically, but if the CPU only has a certain number of lanes left(if a card is occupying another slot connected to the CPU's controller), then the card can only use what's left.
