you should be able to manage a HD 6850 with no problem

Problem with a Radeon HD 6850 is that it requires two 6-pin PCIe connectors, and that power supply only has one. And it only has three 4-pin standard peripheral power (Molex) connectors, you'd have to use two of those to supply the remaining PCIe power slot on the video card. So if you're fine with only having one 4-pin peripheral cable for fans, etc then it will be fine. If not then I think a GTS 450 would be a good option, as it's not very power hungry, more powerful than a 5770 and only needs one 6-pin PCIe connector.

I have a Antec Earthwatts 650 watt psu, powering Amd Phenom X3 2.8 Ghz, 2 Gb DDR3 ram, and Radeon HD 5770. The psu just barely is enough to power it all.

I'd go with the GTS 450. It's draws a little less watts at idle than the HD 5770, but a little more watts at full load than the HD 5770. The problems on my system were when my system was at full load, sometimes it would crash. Any overclock on either my cpu or gpu also causes the system to crash a few minutes later, and I traced it all back to my psu not having enough juice.

If you had the spare money I'd recommend getting a stronger psu. But if that's not possible than the GTS 450 might be better than the HD 5770.

I was wondering if the GTS 450 is powerful enough to run games at 1440 x 900?
i have an 19" monitor and i don't have to play them at higher resolution?
BTW i think that Antec Earthwats could power any single GPU on the planet with a quad core

Looked up a review of your PSU:

:ouch:

It wasn't very favorable. :heink: I would seriously consider a PSU upgrade before getting ANY new GPU.

Even this:
http://www.newegg.com/Product/Prod [...] 6817371033
would be better. :bounce:

Don't cheap-out on the Power supply :non: It's only false economy, :fou: and bound to cause you problems in the long run. :cry:

are two great places to get reviews. and as always:"Google is your friend" when it comes to researching! :love:

It can. One of my systems has an OC'd Q9550, 4 GB RAM, a GTX260 - a card requiring more power than a 5770, a Gigabyte EP45-UD3P motherboard, 3 hard drives and an optical, and a Soundblaster card.
Running 3 instances of Prime95 to load the CPU and 3DMark06 to load the GPU, it pulls 375 watts from the wall as measured by my Kill-a-Watt meter. Figuring 80% efficiency, the system pulls 300 watts from the PSU.

thnx for the reply guys
i gues i will go for an ati hd 6850 becouse i dont need extra hard drives, im ok with 500 gb. what kind of a converter is that i need to convert 2x4 pins to 1x6 pci-e ?
please post me a photo or a link.

Reply to jimmy19

The 6850 should come with the needed molex to PCI-e adapter.

Reply to clarkjd

HD6850 needs only *one* PCIe-6 power slot: see this image

The Earthwatts PSUs are rated for continuous output, meaning that you'll be getting at least 650W output while running.

Barely enough? Don't think so

Can't believe I made just a silly mistake, maybe AMD's naming has confused me afterall.

THNX guys for the replies im new on this forum.
i guess my new pc will be AMD Phenom 2 x4 945 95w, 4gb ddr3, and an ATI Radeon 6850. The salesman told me it could handle an 6870 but its out of my price range and i wont take chance with the PSU
