Specs: Windows Vista Ultimate, 2.793 GHz / 2045 MB
I've finally settled on a final list of components for a new computer and would like to know if the listed power supply will be adequate for the components listed:
ASUS P6T WS Pro motherboard
Intel i7 920 2.66GHz Quad-core processor
Crucial Ballistix 6GB DDR3 RAM (later to be upgraded to 12GB)
nVidia Quadro FX 1800 768MB DDR3 Video Card
Corsair 650W Modular PSU
Cooler Master case

As long as you stick with the work station graphics then that PSU should be more than adequate.

The CPU you chose is a real power hog. I have read numbers up in the low 300w range.

The graphics card is rated at 59w according to nvidia. Some of the high end gaming cards can draw 200w +.

Wow, what a difference in power draw between the cards! Also, I had no idea the i7 processors used so much power. Seems like they would get pretty hot.

Thanks for the info. I'm sure I will be sticking with the workstation graphics card, although I hate paying the higher price.

Thanks again.

You could easily get away with a lower power Core i5 & save yourself a $100 on the CPU cost alone, not to mention the engery cost over the life of the system. You'd have to go with an LGA 1156 motherboard though, which isn't necessarily a bad thing. You'd *probably* be able to save some on the cost of the board too.

jam, I have given up on the idea of moderation with Jude. He will just have to learn the hard way. I did the same thing a dozen years ago or so. Experience is the best teacher.

Jude is learning though. He is going with a workstation graphics card with will serve him well. I am not sure all that memory bandwidth can be used or not.

There is nothing wrong with the proposed build other than the fact it may be overkill and more expensive.

Yeah, I know there's nothing wrong with it, but you know how I am when it comes to spending money needlessly. You put it very well in the other thread...something about buying a Corvette just to drive back & forth to the grocery store?

I agree, however, we don't really know the size and complexity of the files Jude works with.

Face it jam, you and I are both cheap. I pride myself in that.

That said, after hearing the facts and weighing in on them, Jude has made his decision. He just wanted our help with the PSU.

There is a good example of the mindset.

newegg.com has two 650w PSU listed. The one Jude picked is ten bucks or so more than the other but has a 7 year warranty instead of 5 years. I assume that may have been the determining factor in making the choice.

He did state in the first thread he was looking for future proof. As we know there is no such thing but you can stretch the time frame with the right purchases.

I buy second or even third tier hardware for two reasons. First, is that is all the speed.

Second, I look at TCO (Total cost of Ownership).

Jude, good luck with that rig. Feel free to return with more questions as they arise. Hope we didn't beat you up too badly.

I didn't look at your case selection before because a case is a case. However, I notice that case has a bottom mounted PSU. I don't know if that is a good idea or not. Heat rises and the PSU exhausts much of that heat.

Make sure to install a large rear case fan at the top rear.
