Graphics Card Power Help

[Daltonv]

I am trying to upgrade a new computer's graphics card to provide me two DVI ports. The only card with two DVI ports available at my local store was the NVIDIA GeForce GTS450. I am trying to install it into an HP Z200 Workstation desktop. I noticed that the GTS requires a power adapter, which then splits into two separate connections. From what I can tell, the PSU in the Z200 only provides a single connection. Is there a configuration I am missing, or will this graphics card simply not work for this computer? Please help!

Your power supply is probably to small. I think your Z200 has a 320 watt power supply and the GTS450 requires a 400 watt power supply (with a minimum of 22 amps on the 12v rail.
