i am building a new rig for video editing and cg animation Here are my hardwere :
intel 4th gen core i7 4770 Haswell processor
Gigabyte G1 sniper m3 motherbord
8gb (4+4) 1600 bus speed crossair vengence ram
intel xfi Titaniam sound card
Nvdia GTX 550TI 1gb DDR5

will i be able to run it with thermaltake 400w psu without any complication?

400w is the absolute minimum power requirement for a GTX 550ti. I recommend getting at least 500-550w for a little headroom. They are usually the same price.

At the moment I am running an fx 6120 overclocked, with a liquid loop and a gtx 550 ti myself and I have no problems out of my thermaltake tr2 PSU although its a 430 watt.

I believe this, but I also believe that if you upgraded to 550w your system would run even better.

MAX power draw is 116 W.@12V=~10Amps from a single 12V rail for the video card. Putting a PCIe sound card in there is pushing your luck, I would think. Does the PSU have a single 6-pin PCIe connector or do you need to us a splitter cable?

I'm quite sure it would although for a basic yes or no answer, yes it would run. Personally though I would follow turbo's advice and upgrade to a 500 watt if allowable as it would provide more stability and more room for upgrades in the future but in short yes it would run it.

There are two things that you should never skimp on. The motherboard and the power supply.

thank you for your information and what about i replace GTX 550ti wth my current gpu ATi 4850 then will i be able to run it? (as i am really runing low on budget at this moment can't afford to buy another psu)

If you want my honest opinion, save up for a beefier power supply and a more qualified card for rendering. The 550 ti is a great budget card but it is just that a budget card with a paltry cuda core count (192) that won't give life changing render acceleration compared to a comparable radeon. I would save up a tad bit more for atleast a 660 and a 500 watt PSU.

If you have both GPU's at your disposal then use the 550 ti as it draws only 6 watts more but either way you really do limit yourself in the future with that PSU. If you can't upgrade it now then get the 400 watt but I strongly suggest you upgrade it in the future,
