Can anyone suggest a video card or the specifications I should look for to support 3 displays?

I have a client who wants their workstations to work with three displays with VGA and DVI connections. This is a business setting not a high resolution/graphics requirements.

The systems have PCI, PCIE and PCIx, PCIXE and X1, X16 slots.. the systems vary based on the model (all Dells).

I don't want to change out the power supply but may need to ....

Most video cards will only support 2 outputs.

As a result we ended up going with this:

It's a usb video card that supports a DVI connection, and runs 3 monitors just fine.  Fine for business.

get  2 displayport to DVI (active) adapters and you should be able to get 3 off a card like this

PS, according to reviews you need the adapters to be active, and the included one is mistakenly listed as active when it's in-fact passive.

Radeon R5 230, supports 3 monitors, has DVI, VGA and HDMI so you need just one converter from HDMI to VGA or DVI
and it only needs 20 watts at max load, but this card has no good performance for 3D but if you only need to display default 2D-Desktop its perfect for your needs. Doesnt need a extra cabling from PSU, although Dell Precision should have it already, power over PCI-E is enough.

We use the AMD FirePro 2450 cards, which support 4 monitors on our trader desks.  Bit old now, but still available.  Card has 2 ports on it, which split to 2 DVI connectors each, giving up to 4 screens, and you can fit VGA adaptors too.  

Cards are passively cooled, helping quiet running and long lifespans.  Cards are low profile, easy to fit in smaller cases.

The new version is the 2460, giving DisplayPort and DVI outputs, which presumably you could convert back to VGA with adaptors too.  Not played with that myself though.
