And in all fairness its not really that big of a deal. They have google.




It states 9 times outta 10 in the thread weather or not they want to "maybe" upgrade later on or if it doesn't it's assumed. I mean come on this is OCN, upgrading is like an every day occurrence around here. Personally I don't think this thread is necessary or needed you could have had a rant in thread where your IRE was aroused. But hey that's just my 5 cents.....
He's "ranting" because he's entitled to.
It's common knowledge that Phaedrus is very well informed when it comes to PSUs.

Add to that the fact that this happens in every thread where PSU recommendations are brought up.
About three hours ago someone was told that a 550W PSU couldn't handle a single GTX 580 when the rig was for a business and was never going to be overclocked.

What I think Phaedrus is getting at is that people need to research the power draw of cards/ CPU etc. before recommending a PSU because pulling numbers off the top of your head helps nobody when you could just shut up and let someone who Has done the research jump in and give an informed opinion on the matter.

I wonder if there is some sort of application you have to fill out first before Pahedrus will sell you his 1200W P/S? Are the manufactures the ones that are driving the sales of these high capacity P/S's or is the manufacture simply giving the customer what they request?

1. I'm right here, you don't have to talk about me in the third person.

2. I'll sell it to whoever wants it, but it would be stupid to buy it for anything less than a tri/quad SLI rig.

3. A little of both. Higher wattage PSUs tend to have higher profit margins; also buyers think they need more than they do, and/or it enlarges their epeen. Neither serves the customer's best interests (ie, best quality for their needs at as low a price as possible) and it wastes energy (read my article on the 50% load myth; also, energy used in manufacturing).

I was in CanadaComputers recently and mentioned that I'm going to be adding a second video card and that I've got a 650W power supply (which I purchased specifically for crossfire purposes).
Anyway, a couple of the salespeople there start trying to lecture me that I need AT LEAST a 1000W p/s for any dual-video card system. I'm sure they make a lot of money selling such power supplies, but that doesn't make them right.

To settle the argument, we called up XFX support. XFX is one of the only company's that produces both high end video cards and power supplies. So they're in a good position to know the right answer. What did XFX say? For two HD6850's a high quality 650W p/s is plenty. Which is exactly what I've got.

If it were two 69xx's, then something a little bigger like 850W would be preferable.

Before I bought the 650W, I was running a 500W. Which is more than enough for the vast majority of systems out there.

850W is overkill for HD6900 series cards. They're still just 160-190W each. HD6850s are like 100W each; you could Crossfire them on a quality 550W.

I'd love to hear your thoughts on my case if you don't mind Phaedrus

so an xfx 550 can crossfire 2 oc 6950 with an oc cpu ?

Aren't PSU's a case of "better to have too much than too little"? There's not an awful lot of price difference between a 650 to 750...

He was pretty clearly referring to 6850s CF when he said 550w.
