Hello

I bought a GTX 570 and Gigabyte says it needs a 550 watt psu at the least. What size psu would be good? 550, 600, 650、700, 750, 800, 850?

I am building a SB computer and will get a i5 2500k or i7 2600k, 2 hd(maybe 1 raptor and 1 regular hd if can afford raptor), 1 DVD rw drive, 1 Soundblaster audio card, and I might oc the processor and gpu.

If I want to go SLI, what wattage should I get?

If I want to future proof it, what wattage should I get?

You need an 850W unit preferably a Corsair,XFX,Antec,Seasonic.

Op what's your monitors native resolution?


1680x1050 but later I am going to get one that is 1920x1200.

So 850watts? Remember Gigabyte says for one I need 550watts so shouldnt it be lower to make it SLI than 850watts?

You should get a good 550W unit for a single card, it should have ~40A between its 12V rails, one from Corsair, Antec, or Seasonic would be good. If you want to SLI you need at least a good 750W unit, one from XFX, Seasonic, Corsair, or Antec would be my first picks, sometimes you can get an 850W from one of them for less depending on the deals of the day so look at those too.

The 570 needs a lot of power so dont get the cheapest 550W unit you can find, it wont survive long, you need a quality unit to keep up with it.

So a good 750 watt psu will be good for Sli, and adding the different things I said I would add?

Here Scythe is a big one in Japan. I am looking at the Gouriki3 or the Chouriki 2. The Gouriki 3 is bronze 80 Plus and the Chouriki 2 is Silver 80 Plus rated. I can get a Antec True Power 750. Most of the American ones are expensive to get here.
Will any of these be good choices?

The TP-750 is a good unit i would go for that one. The 80+ rating of a PSU only tells you the efficiency not the quality of it, you can make a really efficient unit but use bad caps that will die in a year and it will pass 80+ easily but be a crappy unit down the line.

As long as you arent trying for a super OC on it then the TP-750W has plenty of power for the system as you described it, its capable of more than the 750W it says on the label at normal temperatures.

One thing i would do different though is skip the Raptor, a 1TB drive like the newer Caviar Black or the Samsung F3 1TB is actually faster for much less or for about the same you can pick up an SSD which is much much faster and uses little power.

What is your idea of super oc? I might OC the cpu by a little, and maybe the gpu, but not major oc.

I will look at the Antec. I will look at the Scythe too, I know they are supposed to be good(the models I am looking at.) The stores here are kind of to the point about the quality of the electronics here, it is a Japanese thing.

I would keep it under about 15% for the GPUs as they are the biggest power hog, the CPU isnt a huge power hog relative to SLI GTX 570s so you could OC that quite a bit, probably up the the limit of stability and still be safe on power consumption.

start thinking about 1600p or more monitors when you go with 2.
Psu any quality psu of 750w and up will do. Corsair 750w or 850w units will be perfect.


Ok, since I am going to use a 1920 x 1200 monitor I do not need to SLI? I can still run two monitors off of one card correct?

So if I do not need to SLI, will 650 or 700 watts be fine for what I want?

A single GTX 570 is good for stuff on high or very high today at 1920x1200 however if you want to max stuff out it may take a second, and we dont know what the games of the future may need. Stuff like Metro 2033 already need a pair of cards to perform well on high settings.

You can run dual monitors off of a single card without an issue.

Your card can run on that resolution fine. You'll only see 60fps with it. Adding another you'll still only see 60fps with it. So you need to up the native or add more monitors or hope all the games that gets released uses heavy tesselation otherwise your not going to see your moneys worth

Remember for 3d 120mhz monitor


Ok at this point there is no need for SLI. Thanks

So I should stick with a 650 or 700 watt psu?

not unless you add more monitors or get a higher resolution monitor. But you can play with it lag free until it starts to struggle then you can add another. That will be a while though but that means you might get it cheaper then.


Ok

So I will tyr to find a good 650watt or 700 watt psu. If I find a good 750watt for a low price, I will get it so I can have it incase I do SLI later.
Good choice?

If your going single gpu yes 650w is fine if though you have any plans at all to sli or crossfire in the future go with a 750w now and then you will be ready for the second gpu and not have to worry about upping the PSU then.
You never know when a good gpu deal may fall in your lap better to be prepared now. But its up to you.
