2x EVGA 9800 GX2 - Page 2

post #11 of 24
All of you guys are just way overestimating. I can tell you that my PSU can run that system given that the 9800GX2 uses only a few more watts than 8800GTX/Ultra on full load, plus I have a million fans.

There's no need for 1000W or above, what you only need is a Silverstone DA850: http://www.newegg.com/Product/Produc...82E16817256022

I think a 1000W would do just fine. Did you have any particular PSU in mind? A few I would recommend in the 1000W range would be Ultra X3, Corsair, Thermaltake Toughpower, Xigmatek, any of the Silverstones, PC P&C and OCZ EliteXStream.

Of course it'd do fine, it's unneeded. Read my previous post.

There are a couple of members here (like Mhill) that have a pair of GX2's and they are not happy...

They just don't provide a performance increase in anything they have tested (except crysis to a small degree).

Huge waste of money.

We can talk about driver immaturity all day but the bottom line is for $1200 in video cards you should get $1200 in performance. And you won't

I can link about 10 reviews that show a pair of sub-$200 8800GT in SLI are faster than a single GX2.

Get one as mentioned above or better yet, get a pair of 9800gtx instead. It will save you money and likely be faster than you require...

Your New PSU:
http://www.newegg.com/Product/Produc...82E16817256038

Huge, powerful, big, black, modular, monstrous, and for $400 a bargain, and probably the best 1200W PSU on the marked (with the possible exception of the PC Power & Cooling monster, but that one is $150 more expensive).

The XH1000 is nice also, but only delivers 80A on dual 12V rails... nice, but.. I'd get the extra 15A the Silverstone pushes.

It really all depends if he plans on OC'ing. An OC'ed quad can pull upwards of 200W and the 9800GX2 at stock can do the same. So we are probably looking at 700W when the gfx cards are overclocked plus whatever peripherals he'll be running. On top of that, I prefer to not run PSUs any more than ~70% of their maximum rating for longevity. So yes, he can buy an 850W and it will run just fine but he will be putting a lot of stress on the PSU. I usually try to be conservative when estimating power and then give myself a little buffer zone. He's spending a couple grand on hardware, the difference between an 850W and 1000W will be ~$50. At least I'm not recommending a 1000W psu for a single card dual core set up, which I have seen happen before.

This whole rig is overkill and unneeded... as is most everything we do here.

Does that stop us? Heck no.

I don't know about 2 9800GX2's. I have one, and yeah it was a nice upgrade coming from a 7950GT but if I had it to do over again, I most likely would have gone with a less expensive SLI option.

I have a PC Power and cooling 750 running everything, but I think I'm pushing it
a bit. 2 hard drives, 9800gx2, DVD, q9300, DD 12v-D 5 pump and 4 120 mm fans.You never know what you'll add down the road or how much juice you'll need, so in theory the more the better.
