Need GPU - Power concerns

[mastrom101]

My Computer was running fine with a 6770, but i returned it and am looking at getting an upgrade.

My concern with a 560, 560 ti, 6850 or 6870 is that they draw more power. I do have a 600 watt PSU, but it is rumored to not be very good. However, Cooler-Master told me that my PSU would be compatible with all four of those cards, and if it is not, they will replace it with a new one. They claimed that it can deliver its rated voltages.

Here it is:

I am pretty sure the 7770 uses less power than the 6770, while still performing better. is this true?

Here are the cards i had in mind, can somebody tell me if it will work?
http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=1241686&CatId=7005 (Pre-OCed)
http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=1368436&CatId=7005 (REG)
http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=555335&Sku=E145-1564 (SC)
http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=1781498&CatId=3669 (OC TI)

The first one looked the best to me only because of Shogun 2.

This PSU has to last ~3-4 years, preferably 5 if possible, so capacitor aging must be factored in. The warranty included with the PSU is two years.

Last note, the 7770 is supposed to use less power, but it requires the highest PSU voltage (600 watts)? is that a mistake?

With a 600 watt psu you can pretty much run any single gpu graphics card short of a 590/690/6990.

Edit: And yes, that 7770 600w thing is definitely a mistake. You can run a 7770 on a <300w psu.

Thanks , and thought so

My concern is that power supply was rumored to only deliver up to 450 watts. I find that a little low, maybe 550, but 450 seams too low. Even a no name company would not lie about 150 watts worth of power, and cooler master is pretty reputable. There is only one site that said the PSU could not deliver, and it could be a faulty model. The rest of the bad word comes from people who red the article, but on tigerdirect and newegg, it has good reviews (4-5 stars), so i'm on the edge.

Both CM and tiger direct said that it would work fine. I have the call to tiger direct recorded and the chat to CM Screenshoted and saved as a PDF, that way i have proof if anything goes wrong.

I think I'm going to have to trust CM on that one, but in worst case scenario, will all those cards all run with a 550 watt PSU, along with an 2500k, asus MOBO, 7.2K HD, etc?

Two, what about capacitor aging? Is that a big factor?

Third, of those cards, which would you pick? I like that XFX has a good warranty, but im pretty open to any reliable brand. I'm really paranoid, so a lower power model would be best.

I'm going to leave this topic open for a bit, too see some more feedback. Hopefully somebody with a CM P+ PSU will see this.

Coolermaster is fine, and not only that, for a long time I Crossfired 4870's on a 30 dollar 500w CPU. it was some cheap noname brand and it still works perfectly today.

I had some troubles with XFX in the past but it was just an RMA issue that they kinda screwed me on. I ended up solving the problem myself.

That ZOTAC GTX 560Ti is the fastest there. That thing looks so cool too. I think they're a pretty good brand but I've never bought from them myself. And Capacitor aging isn't something to worry about, Coolermaster isn't a super high end brand but they make good products and I don't think you have any real reason to worry.

Yah the 560ti looks like a good option. The only problem is that it's a little bit more, and that i wont receive Shogun II, which would give me another $20. I'm trying to decide if it's worth it or not, because i'm not playing any super high-end games.

There's a good chance i'm going to give you best answer, but I want to keep the thread open for someone else with a CM Xtreme Power+ 600watt to comment on first.

Thanks for you help!
