Hi,
i am going to get a GeForce GTX 550 Ti.
My question is: what is the best PSU I can get for it?
I currently have 450W and a Geforce 210 (it uses about 300) and i know my computer uses around 100W, the 550ti uses 400W.
My two options are:
Cooler master Power Supply 240-Pin 600 Power Supply RS600-PCARE3-US​

OR

Thermaltake Power Supply 240-Pin 600 Power Supply W0388RU

I would go with the thermaltike. It is cheaper and appears to have better reviews. It also seems quieter.

You might want to look around a bit more, though. $65 doesn't seem like a great deal to me.

nVIDIA states that the GeForce GTX 550 Ti has a Maximum Graphics Card Power of 116 Watts. I don't know where you got the 400 Watt value from.

Even if the GeForce GTX 550 Ti is manually overclocked and running Furmark stability testing it won't draw any more than 183 Watts (i.e. using a ZOTAC GeForce GTX 550 Ti AMP! Edition as the worse case power draw example).

For a system using a single GeForce GTX 550 Ti graphics card NVIDIA specifies a minimum of a 400 Watt or greater power supply that has a combined +12 Volt continuous current rating of 24 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

If your current 450 Watt PSU has a combined +12 Volt continuous current rating of 24 Amps or greater and has at least one 6-pin PCI Express supplementary power connector then you should have no problems.
