The card itself consumes at most 38W (not 380W). What other components do you have? If you use a dual-core processor and one or two HDDs, 150W is enough.

TDP rating is for max dissipation.

Under normal use, it wouldn't hit that rating.

I have a 5750 (with a separate power connector), 7 hard drives, 2 optical drives, an ATX board with a 65W E6850 along with 2 PCI cards and a PCIE TV Tuner. In addition, there are also 5 fans (230mm (2), 140mm (2) & 120mm). I have a 850W PSU powering it, but the entire system idles at 150W-160W and under load (playing movies, watching TV) runs at 170W-175W.

I believe you would be fine with a 150W supply if all you want to do is playback.

What's the rest of your system specs? It'll be iffy at best IMO.


What about a 5450 instead? It'll be cheaper (less than half the cost of the 5570), only 19 watts at max, and silent cause it has no fans.


the case is Athenatech A1089BW.150 and the link to the product is http://www.newegg.com/Product/Produc...82E16811190112


the processor is i3 550 and the motherboard is Intel DH57JG

if I buy a 5450 do I have to get one with 512MB or 1GB? and DDR2 or DDR3, which one is good?

one 3.5HDD and one 5.25 Optical drive.

The MB Intel DH57JG is one of the lowest consumption, the 73W TDP of the core i3, plus the 43w of the graphic card, is likely to have no problems.

But those close to the limit if the components are stressed.


You should also consider the quality of the PSU, essential in this case.

I would try the i3 on-die video capabilities first but if you still want a card then the 5450 with 512Mb is all you need for media playback.


As already mentioned, I'd question the quality of that supply too.

Cam across this post during my searching for something else and thought I'd add that I'm currently running an i3+H55 mITX+5570 on a PicoPSU. I don't think I've had any problems yet, but I'll connect it to a wattmeter later on to see how it meassures out.
