Does SONATA 3 500W power supply is enough for GTX260?

It depends on what else you put in there. That is, how many disks, fans, lights, what CPU, whether you overclock, etc.

That PSU is an Earthwatts 500W with 2 rails of 17A each. That's pretty low for a GTX 260 IMO. Also, the Sonata doesn't have the appropriate cooling for such a card, I think.

I recommend you get yourself a RC-690 case and a 650TX PSU instead of the Sonata.

You probably need a higher wattage psu.

This is mainly what I'm going to buy.
I got 2 hard disks from disk computer that i will use with the new computer (2 different hard disks - Western Digital and Maxtor hard disks)

The only thing I'm just not sure about is the computer case
that where you guys help me  

OC - not planing to do so

We will just have to wait until the real specs for the card is released, like PSU requirements. You may or may cut it with that PSU.

Better yet, skip that case entirely and go for a case and a good PSU.

I'd recommend a $70 Antec Three Hundred Case which will house 10.5" GPU's like the GTX 280 without eating into the hard drive case, although to remove the hard drive, you'd have to remove the GPU first if it's the 10.5" variety (longest cards). Other 2 HHD slots are fine. Then throw in a good Antec/Corsair/PCP&C PSU and you are set.

Sounds like a very good setup. Yeah, RC-690 and 650TX should do nicely. The Sonata not so much,

RC-690 $104 or $80 including shipping

Or maybe the Antec 900 case, if you like flashy blue lights and the PC won't be in the bedroom:
$100 at www.buy.com, $142 at newegg

The P182 is also nice, just a bit expensive at $140. No flashy lights, quieter than most other cases.

Actually the real specs have been released already

Another thing - I'm not from the us.
I live in israel.

i checked the case and PSU the first guy talked about, it about 100$ higher from the original budget.
i don't mind paying more to be 100% sure the computer can handle the GPU card

We know the requirements, kind of:
http://www.tomshardware.com/reviews/nvidia-gtx-280,1953-25.html
Looking at those results, you see the GTX 260 consuming just about as much as the 9800GTX.

Or you can look here:
http://www.nvidia.com/object/geforce_gtx_260.html

nVidia recommends a minimum 500W PSU for systems with a GTX 260. Of course, if you have a quad CPU in there and more than 1 disk and more than 1 fan and so on you probably want more than the minimum recommended PSU. Also, PSU efficiency tends to be best around 40%..70% of the PSU's range, which means it's better to have a big PSU used at, say, 60% of its max than a smaller PSU used at 90%.

Edit: LOL, you found that link on nVidia's site at the same time as me  

I have another question - can the GTX260 get into the RC-690 case? it pretty big \

Edit: I'm fast

500W should be good. May be cutting it close, don't overclock at the least if you try the EarthWatt 500W.

It should fit in the RC-690 all right. Even the 8800GTX fits in that case, and it's almost 11" long. You can put even two of them in there.

The Sonata 3 also can fit an 8800GTX, so it should fit the GTX 260 too.

However, I'd still prefer the RC-690 for a gaming machine because it has 3 fans (and room for 4 more), while the Sonata has just one. Don't get me wrong, I love the Sonata 3, I have one at work right now, it's just that it's not designed for systems with high-end video cards that dissipate a lot of heat.

So I guess my new case and PSU are RC-690 and 650TX

thank you for the help! much respect
