So I've been hampered consistently with the 29/59 bug. Get it pretty bad on premium channels and also get the flickering. Turning dynamic contrast off hasn't helped. Currently using the AMD A4 5300 Trinity 3.4 ghz with GPU. I'm looking into the HD6450 since it seems to handle this problem well according to most members here. I'm looking at a low profile fanless one such as this Asus one http://www.newegg.com/Product/Product.a ... 6814121439.
The question I have is that these say a PSU of 400 watts is recommended. Mine is currently 350 watts. It doesn't seem like this card would need that many watts, but would like to get an idea of what PSU others are running this on. Mainly the only thing on my system is the Infinitv 4 pci, external hard drive (has its own power plug), SSD hard drive, Blu Ray drive, one 80 mm chassis fan. I may be adding an internal hard drive soon as well. I use it for tv, recording, movie playback, some 3D which works great on my current setup.
So will my PSU cut it?

The fact you have an SSD for OS and an external mechanical hard drive, you should be comfortably sweet.
/edit - careful with fanless though. I don't see one on that GPU. Especially when four infini tuners are working hard, that's quite a bit of heat around the GPU area.
I would always go with a fan cooled GPU that can speed up and down when required.

Good point. I will look at ones with a fan.

I got this one from Newegg for $15 on sale & after rebate. It does go on sale once in awhile.

I also was concerned about the PSU. Most comments I've read say the video card manufacturers error on the high side because they presume that since are using a video card that you probably have done other upgrades which use more power.
I have an Intel G620 CPU and before adding the HD6450 the HTPC used 37 watts.
After adding the HD6450 and 2 dual tuner cards is uses 56 watts, and that's while recording 4 programs at the same time while playing a 5th different program.
Take a look at page 20 on this link regarding PCI Express slot power specs.
http://www.pcisig.com/developers/main/t ... 469f57e5f1
An x16 slot can only supply 75W for a full height card and 25W for a low profile card.
So the most that a low profile HD6450 card can draw from the slot is 25W, at least if they conform to the specs.

Great! Thanks for the links Mike. Looks like I will be grabbing one of these at some point. How are you checking your watt usage, a meter? Thanks for help guys.

FWIW my PSU is a 430W Corsair. It is way more than I need & is not operating near maximum efficiency, but it got decent reviews & the price was right.

I would stay away from a GPU with a fan, because I wouldn't want the noise. If you have sufficient air flow in your case, you won't need a fan on the GPU. I prefer fanless. I've actually tested the video card that the OP linked, and it worked just fine in my HTPC. It is currently installed in my daughter's desktop PC, and works fine.

HTPC Specs:
If selected with care, the fan on a modern GPU is virtually silent even at 80% RPM. Think Vapor-X etc.
Our full size HTPC has two chassis fans, one 100mm case fan, one slot cooler, one GPU fan and the PSU fan. All the fans spin very slowly and overall the system runs virtually silent. We cannot hear it from the seating position. If you move closer to the HTPC, you hear the clicking heads of the recording hard disk first and foremost over any of the fans, including the GPU fan.
Unlike barnabas but like the OP, I have an internal infiniTV and heat has to be managed. If you don't manage the heat properly I guarantee you will have heat related problems across the board.

HTPC Specs:
If you remember, I had an InfiniTV4-PCIe in the machine at one time. I also had a fanless video card in the machine. My HTPC has three 80mm case fans, and a 120mm CPU fan. The GPU and the InfiniTV both ran within specifications. It all depends on the air flow in the case. With sufficient air flow, with the air flow routed so that it passes over the heat sinks on the components, the GPU does not need a fan, nor does the InfiniTV need a slot fan next to it.

My case only has two 60mm chassis fans, which was not enough, so I added a slot blower. This allowed me to tune down the fan speeds.
I cannot hear the GPU fan - which I think was your point?
With four tuners in use, that area of the chassis does heat up and it has a knock on effect of increasing GPU temp.
Your point of it being noisy is moot. If it IS noisy, then all that does is confirm the innards of a chassis is running too hot and the GPU fan speed is attempting to compensate. My GPU fan runs at most 50% speed and is virtually silent. Without the fan the GPU runs considerably hotter.
I recommend a fan, you do not, but we can both agree all chassis and configs are different, I'm just playing safe and see lower inside temps because of it.

Sure, I understand. That's why I always mention the airflow in the case when talking about any kind of fanless components. But even if you have a fan on the GPU, it still needs a source of cool air.
When building a PC (or HTPC), the goal is to make the air flow over all the warm components, so you need to install the case fans in an arrangement that will make that happen. I actually made a couple of baffles from cardboard for my HTPC so that the air is forced to flow over all the important components before being exhausted out the back. That allowed me to run the fans very slowly to achieve very safe temperatures while being very quiet.

Not necessarily. It depends on your case. Mine doesn't have very good airflow characteristics. The biggest problem was that there was a short-circuit path between a side intake vent and the rear exhaust fans. So, I made a baffle that forces the cool air that is being drawn into the side air vent so that it is directed into the CPU fan's intake.STC wrote:So, don't get a GPU with a fan but build baffles for your HTPC instead?

Good show. If the ATI drivers throw curve balls at you and decide to change settings (you will find out over time), I know how to lock your settings in place with some reg keys so they don;t move again. Let me know if so.
