Hi. I want to upgrade my (integrated) graphics card to Radeon 6870, but I'm not sure if it's compatible with my motherboard, so please help me.

My other board is ASRock M3A785GX/128M: http://www.asrock.co...=M3A785GXH/128M

Here's the card I want to upgrade to: http://www.newegg.co...1-349-_-Product

Thank you very much.

I think that's it...

PSU might be a little on the weak side depending on manufacturer. Never hurts to have a better PSU. Card should be a nice upgrade :D

Agreed.

This is the product page, specs for the HIS, > http://www.hisdigita...duct2-575.shtml Note that the PSU needs 500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended.

Please post the brand and model of your PSU so we can check it out.

Your existing PSU will not support the upgrade. Product page, > http://www.bccpc.com...c/power_all.htm

I think your in the USA so here is a link to Newegg. One of these will do the trick. My choice would be the Antec TP 650.

Let us know how you get on.

I wouldnt go with an A-Power power supply. I've never heard of them before and your PSU is critical. Go with either of the antec's in iammykyl post

I see. I have one more question please. The graphics card requires a minimum of 500W power, does that mean the whole computer will be using more than 500W of power even if I don't play games? 'cuz I'm getting this card for games.

The min power requirements is for the whole system, including the video card. We usually recommend a PSU with a little more power so it gives a some headroom in case you add more components.

When you start the system and ever thing is loading the PSU draws the most power, PEAK, and then draws less power, CONTINUOUS, when running.

I would also go for one of the Antec PSUs.

Since more power means better for future component additions (such as hard drives?), should I go with this one instead? 'cuz I may get a 2TB hard drive.

Thanks again. Sorry for keep asking questions.

Keep asking, we are here to help.

The Antec TP 650w is all you will need and some.

Am always iffy about buying such items on ebay. Should it go kaput inside the warranty period you would get a replacement from Newegg or similar seller. I think you would be very lucky to get the same service from an ebay seller, they may not be there in six months time.

I see. Then I'll just go with the 650w one from Antec, but when I took a look at the feedbacks for the Antect TP 650W, some said it sucks where as Antec EarthWatts EA650 650W has 100% feedbacks, should I go with this one instead?

Maybe I am a bit cynical, don't take too much notice of reviews on shopping sites, have a sneaky suspicion that major manufactures have teams of writers.

Modular cable management, 5 year warranty, 4 rails, better fan, Supports dual GPUs and dual/quad core CPUs
A more useful PSU if moved to a new system.
