GPU Help

[codemanjack]

I bought a bare bones kit that came with everything but the graphics card. I am going with a gtx 550 to (costs only $110 on tiger direct.com) and was curious if my power supply will be able to support everything.
Power Supply: Thermaltake VM54521N2U V2 ATX Mid Tower Case - ATX, Micro ATX, 450W PSU, 3x Ext 5.25, 1x Ext 3.5, 6x Int 3.5, 2x Front USB 2.0 Ports at TigerDirect.com

Welcome to TechIMO!
Did you mean ti
The min requirements, are for 400watt.

Without knowing the brand power supply, at least, and better the 12volt amps, I couldn't guess if it has a real 450watt.

It will probably work, as a brand name 350watt would work, it may not have circuitry to protect your computer from a failure though.

Unless you have an unusual power demand, like 6 hard drives, in a RAID,, or plan to add a second video card, you size the power supply to the single video card.

must be a Ti, there are no plain 550's.

as to the PSU, since it was a Thermaltake Case, I'm assuming its a Thermaltake PSU, but as said above, we need to know the Brand, Model of the PSU in the case.

also it could help to know the rest of the systems specs as well, how many hard drives, motherboard, RAM, CPU, etc.
