Just got a new 2 gig visiontek 7850 card. Installed it and seems to be having problems. sometimes itll just give me a blank colored screen in shades of blue, red or grey. other times it gives me red vertical lines. its a brand new card and tried installing old catalyst drivers going back to 12.8, tried different 6 pin connectors for the card, reseated the card etc. it just seems to die even without any load at all.

are there any other troubleshooting tactics i should try here?
 
not sure about that. My DVI cable works fine with my old 5770, and I tried an HDMI with my new card with the same results.

I starting to wonder if it might be my power supply. I got a 600w corsair thats got 3 hard drives on it, not sure if thats enough power
 
It's altogether possible you just got a bad card. Hard drives by themselves don't draw a lot of power. Maybe they get up to 40W max during spin up, but they probably don't use more than 10W under normal loads.

The largest amp load on startup for a hard drive I've seen has been 2.5 amp, which is about 30w, but like you said, most normal mechanical drives run at 10w. Also, most modern motherboards don't spin all the hard drives at once when first powered on so no need to worry about straining the power supply. It could become an issue if you house 10+ drives in a raid setup, but even then, you'd have to get a RAID card and most support staggered starting to avoid just this power issue.

If you went through troubleshooting as you say and used both a DVI and hdmi cable in different ports, then it could entirely be a bad card that slipped through the QC. I'd contact the merchant for a quick RMA replacement; I'm assuming you got this from newegg or amazon?

yea amazon doesnt have anymore stock, so I guess I'm not getting a new card.
Oh well, I heard Visiontek isn't the reliable company it used to be, might be better off finding a better brand.

or maybe i should rma with the manufacturer first. I dunno about the turnaround time with them getting back my card. But if that doesnt work either I have until jan 31 to return it to amazon.

You sure amazon doesn't have anymore? Shows up in stock on their website with reference to more deliveries being expected. I'd still go through the merchant first and foremost, plus in most cases now days with RMA, most manufacturers want the merchants to deal with RMA claims with the first 30 days of purchase. Amazon does have good CS support when you need it.

If not through amazon, then I'd probably call visiontek and see how fast they can do an RMA. Make sure you get an email confirmation about when you will get a replacement; don't accept anything over the phone. If they expect you to pay for shipping to them, I'd probably say that's a deal breaker and just return the gpu to amazon and go with a better brand. The 7850 does have their limited lifetime warranty.
 
well thanks for pointing that out, wasn't in stock earlier today.

i have a m4a78t-e motherboard. what im worried about is that it might be incompatible with my board. Have you guys ever encountered an incompatiblity issues like this? I don't want to get a replacement card, have it not work again, and amazon will refuse to accept a second return for the same product. I wanna make sure i have everything covered before making a return.
 
You should have no worries about incompatibility issues now days. This isn't 20 years ago. PCIe is an open platform that's an industry platform.

yea i would think so too. But I also expect alot of components to work too. I never had components not work and its usually a user error issue. But I tried every course of action to no avail.
 
It could very well be a failed hardware if all else troubleshooting has failed. I've had DOA parts from name brands; last one was a corsair.
