Right now, I'm using an HP desktop (model a6223w). Also, I've previously installed an Antec Earthwatts 380W PSU. I've poked around Power Supply calculators a bit, and I think i'd be fine, but I'd just want to double check.I've nothing else installed on my PC besides what came in it (and the newer PSU).

This is the PC I'm using:

You'll need a new PSU if your going with the gtx 260. On Nvidia's site, they recommend a 500w power supply.

The bfg geforce 260gtx I have right now needs 2 power connectors as well.

So I would definitely recommend a new PSU.

It all depends on the A's the PSU supplies on the 12v channels, actually.

Since the page you linked doesn't provide any infor on the PSU, you'd have to open the case and give us the details about the PSU by yourself :p 

Open it up, search for the detail on power draws and look the the "12V+" rail/channel on the PSU. Give us the A's it provides.

Cheers!

PS: A = Amperage

It has 2 12V channels @17A.

I'd say you'll be way too close for it's power requirement.

The GTX260 needs a little more than 22.5A since it draws around 270W+ under full load, using 2 connectors if i recall correctly.

If you have a lof of HDDs, DVD's and such, you should get a new PSU with more Amps on the +12V ramps. Otherwise, you'll be in tight margins.

Cheers!

Hmm. What then would be a cheap, but appropriate option for a PSU? I'd like to spend as little as possible, but I obviously don't want something that'd die. Or explode. Or die in an explosion.

I always like to say the Thermaltakes are awsome buys, since I've have TT's. CoolerMaster's, Antec's, OCZ's and Thermaltake's are my world, but there are a lot of other good brands that I don't know of and some people do.

Now, since i'm half TT fanboi, I'll recomend you one (lol): http://www.newegg.com/Product/Product.aspx?Item=N82E168...

That one should be enough and it's quite $/perf appealing :p
