PSU for the Nest Generation

[Yoshi]

Hey guys,
I am going to go for a Nvidia 6800 or ATi X800 when they come out, but I don't think my 350w Generic PSU will cut it. Can you guys recommend a PSU that will handle those cards. I have 2 drives, 1 HD, and a P4C System

Don't quote me on this but the numbers were around the 600Watt+ mark

Maybe something like this will suit your need: http://www.newegg.com/app/ViewProduc...103-910&depa=1

How about this, I like that it has the cables already rounded , and it has great reviews.

Looks good to me.

I won't quote ya jakk, but the new cards only draw about 24 watts more than the 5950/9800XT.

Recommended is a 480W power supply in conjunction with the 6800 Ultra.

..someone just deleted their post?

Yeah, found where i'd read 650Watts from and sure enough, it was B.S.

Lemme guess, The Inquirer?

Yoshi, THG did a wattage test and found that a hardcore gaming rig only pulled approx 300watts at the absolute highest amount of load. A 6800 uses only a little more power. I bet you could get by with a 350 or 400. But if you want to worry, then go ahead and grab a 600 watt psu. But seriously, computers don't ever pull as much power as most people think they do.

I find a lot of it depends upon how you distribute power accross the various branches of the PSU, for example, putting a couple of power-hungry devices on the same branch, you ,ay find issues with intermittent power loss, as such its usually good to balance them out with a high draw/low draw combo (e.g. a drive and a case fan) on the same branch, in addition to this i leave the Vid Card alone on its own branch. Also of note, though NV have said the power cables need to be from seperate branches, HOCP ran the card perfectly well with two connectors from the same branch.

Nvidia does recommend 480W, but that's probably a way to get around the cheap PSU's out there. However, I wouldn't bank on the fact that hardware sites have been able to run them on much lower wattage PSUs than Nvidia recommended. Generally they use very high quality CPUs and lightly loaded systems. One HD and one optical drive is the norm for their test machines. Enthusiasts will also often run more fans than the test sites.

The only thing I'm sure of is that the 6800 is going to need more power than the X800 (dual molexes), and so will probably run hotter.

Yoshi-

Always buy a very good quality PSU or everything that you put together will probably be at risk of being destroyed if and when the PSU does go out! Remember that it is the very thing that makes the difference between a trouble-free system or one that you might have to constantly troubleshoot.

Also keep in mind that when you shop for a PSU that you've got to make sure that you have enough capacity to provide current on the 12-volt rail for your CPU and any motor driven devices. I also want to point out that many of the PSUs out there are built on the older specs and don't really come up to par for the intended applications and that is why there have been many failed PSUs out there!

Even your well known manufacturers like HP/Compaq and Dell have had their share of failed PSU problems and that is because they use underpowered PSUs (meaning that the wattage rating is far below what it should be). I've seen these come in as Core Returns from the customers that we supplied replacement PSUs to! Imagine having only a 250-watt rated PSU on a Full Tower system that loaded with high-end parts. Yes, I've seen these first-hand and really feel that they are short-changing the customer by selling good systems that have sub-par PSUs.

Like I said, you could believe what you want but I've seen what goes on out there in the real world when it comes to this subject.
You might say that I'm over zealous about this issue but I speak from experience and I've seen too many of these so-called adequate PSUs fail horribly and sometimes taking out some or all of the components inside with it. IMHO it is not worth the gamble to be cheap about the PSU. Good luck!

I second that-- cheap and crappy PSU = cheap and crappy computer.

Don't skimp on it.

I recommand a 500 watt to give you so watts left over
and where did someone find a 680watt power supply
