<$200 GPU for a system with a 450W PSU?

post #1 of 32
Thread Starter 
Hey,

My trusty 8800GT has burned out, and I'm looking to replace it. I have a 450 W power supply (with only one of those special 6-pin video card power plugs) and I'd really like to avoid having to upgrade that.

The cards I'm considering are the GTX 460 and the Radeon HD 6850. Do you guys think I would have trouble running either of those two on 450W? I'm a little worried about the GTX 460, as all the models I've seen require two 6-pin plugs, so I'd have to use an adapter.

In case it's relevant, my system has a 2.66Ghz Core 2 Duo, two 7200RPM Sata hard drives and a DVD-RW drive.

Leaving aside the power issue, my understanding is that the two cards are roughly equivalent in terms of performance. Is that correct?

I've heard some bad things about AMD's drivers. Any truth to that? I dual-boot Linux, and while I don't need 3d-acceleration under Linux, I at least need it to work.

And finally, are there any other good cards in my price range I should take a look at?

That depends: which 450W power supply do you have? I mean, what's the brand and model number?

I don't know anything about the Antec SmartPower, however I personally wouldn't trust it with any nice graphics cards.

Based on that spec sheet, I would say that it's basically a modern-day mediocre 300-350W power supply at best.

Hmm, I was under the impression that if your PSU wasn't up to snuff, you'd just have weird issues and stability problems, especially when under load. Are you saying there's a risk to the hardware as well?

And I'm sorry if this is a stupid question (I'm pretty ignorant when it comes to the minutiae of hardware), but what are you looking at in the spec sheet to know that?

The only thing that I know (or at least have heard) is important to compare other than the overall wattage rating is the amperage rating on the 12V rails, which is 15A and 17A on mine, which doesn't seem too far out of line compared to power supplies with similar wattages on newegg. So what am I missing here?

Use this to calculate your overall power requirements to see if there is room for a GTX460 or HD6850: http://www.thermaltake.outervision.com/


Another choice would be an HD5770. Its a bit slower than the 460 but requires less power.

Here's some game benchmarks comparing the GTX460 and HD5770 http://www.anandtech.com/bench/Product/172?vs=156

I'm a fan of the 460 or the 6850 for the sub 200 price.

and I'm partial to Nvidia... but still
