What Would Be A Good Psu?

I'm planning on the Geforce GTX 275 and was wondering what would be the necessary changes that I will go about in my PC along with the PSU. Will a 800 Odin GT or something from Gigabyte etc do or do you have something better to suggest?

Also will I be able to run my current 8800 GT with the GTX 275? They are SLi ready I suppose so will I be able to install both of them?

 

4890>GTX 275 due to pricing... GTX 275 is over priced... at least in the US.

you'll be able to run it, but not in SLi, you can use the 8800GT for physics though and the 275 for gaming(or the 4890 in this case)

what's your current PSU, and what is your budget.

 

My budget is around 140$. Would my current motherboard (Foxconn P35AP-S) and Intel Core2Quad Q9550 be compatible with 4890? Also, crossfire and sli cannot run at the same time, can they?

My current PSU is a Gigabyte 450W.

 

using one card for physics and another for graphical rendering IS NOT SLi.

let me repeat that IT IS NOT SLI.

the 8800s and GTXes cannot run in SLI together.

and let me get back to you ona PSU recomendation...

 

LOL I never knew how Sli or Crossfire worked.

P.S I just read this review at TechSpot which concluded that the Geforce GTX 275 performs better than the 4890 in most cases. Whereas the 4890 only performed well in 3 of the 12 total games tested.

get sumthin with lotsa volts

 

Like an 800W PSU or something?

 

how many volts is that?

 

I'm too lazy to check it for you, but the product specs should say how much watt it requires. I think it should be around 600W.
You also need to power the other components in your PC, so 800W can be tight. I'd go for a 1000W.

...

You serious?
How about 12V max.
Unless you are planning an in-house barbecue.

 

12v doesn't seem like many.

 

lol.. Inverse, how many volts does your PSU have? 18? 32?...

Also, I think PSU with 1000W would go out of Budget, I am able to buy it but then I'll be spending money on these two computer parts again, graphic card is needed but PSU hm..

Anyway, what good PSUs can I get for around 120$

 

PSU's don't go over 12V.

Get a 800W if you want, they are indeed cheaper.
But if your system shuts down while playing games, or won't boot at all because of the lack of watt your PSU can generate, you'll regret buying it in the first place.

Get one of those watt meters at an electronics store if you want to be sure.


Edit.
Hard for me to make real recommendations for PSU's, I live in the Netherlands and prices are different than in the US.

 

I'm not in the US which makes it even difficult to cope with the prices.

Also, I am going for a 1000W PSU then, would probably cost me around 180$ or less.

 

Realistically, rated wattage means sh!t all. Want you should be looking for is a PSU with 1 (ideally) or 2 high Amp 12v lines. Since the main draw from the PSU will be your video card, having a powerful single 12v line is much better than a high rated PSU with many 12v lines. As it is, an i7 rig with a GTX275 would be lucky to draw more than 400w at peak load, and wasting money on a higher wattage PSU with weaker lines is stoopid. buy a 650w MAX PSU. Anyway, normally the good quality units can exceed beyond what they're rated at, whereas the cheaper high rated units are lucky to actually be stable at their rated wattage.

 

You do have a logical point there though I would like to consider all the point of views before spending a few of my savings. But yeah if someone doesn't come up with anything within 6~7 then I might just go for either an 800W or 650W as you said Inverse.
