will 430W be enough?

[board123]

i thought a smart guy would know how to measure these.

You thought right, so please explain how you're measuring the numbers you're quoting.

Didn't you make this thread to ask for help? We're helping you, but you're not helping us by being a dick.

[mysticalinfluence]

No. Get a 600w - 750w this will leave a better margin.

Not like it was much more.

You're trolling I'll eat my shoes if that rig is pulling more then 300 watt. Proven time and time again that nothing aside from X-fire,SLi rigs pull more then 300 watt. OP best way to know forsure is to buy something to measure the power draw at the wall. it's great tool to own and cost a few dollars. The Antec should be fine but generally you always want quality PSU Seasonic,Corsair etc.. no cheapo tin cans. Your PSU,video card could be dying and this the reason for the lockups.

Antec Earthwatt is an 80+ Seasonic unit.

Only early Earthwatts where built by Seasonic then shortly afterwards Antec switch to having Delta build the units. They're identified with the serial number EA-430D etc....

c'mon, i bought the 750w already. what else is there to discuss about? if you keep saying bs to me it will make me feel i made the wrong purchase. thats not helping me, smart.

very good advice, thanks!

You did make the wrong purchase, but now that you know you made the wrong purchase this time around, you won't make the same mistake in the future.

You clearly don't have a good way of measuring power, otherwise you wouldn't have made the wrong purchase to begin with. A smart guy would realize that.

No problem it's huge myth that we need 1000 watt beast to run are rigs marketing usually blinds alot people that don't know the truth. Slient PC review or Jonny Guru proves this in there forums all time.

The purchase was not wrong. Unless OP couldn't afford the extra $ between a 500W & 750W p/s.

The most important thing is that OP solved the computer crashing during gaming issue. It is never bad, when you spend money and solved the problem.

We have had threads where people have purchased new p/s, RAM, then HD or even a motherboard.

So OP did pretty good. OP should feel good.

[board123]

My mistake - it was a suboptimal purchase.

Just tested on mine. According to my UPS, my machine with a single 6950 2GB is using 299W while in Stalker1 or Stalker2. It also uses 290W while in X3. Those are older games but I am sure I can do other stuffs in the background to push it over 300W.

Your still not consuming more then 300 watt are you? I didn't say go ahead put X-fire rig on 300 watt. Remind not buy HD6950 because that power hog if it's using that much power.

What happened to your English? I remember you used to be fine, but now you're barely comprehensible.

Not trying to be rude. I'm just curious. It's almost like two people are using your account.

And I am not using a top-of-the-line video card either (there are still 6970). Also, all my components are not overclock. I am not saying you are wrong. I was just curious at what you are saying so I went looking. Then I found out your claim is cutting very close.

Quick google and here are a couple power comsumption chart I found:

(measure video card only?)
http://www.techpowerup.com/reviews/H...D_6970/27.html

(measure whole system?) Quite a few single card got pass 300W. So either this site is wrong or you are wrong.

Don't want to get into fanboy argument but calling 6950 a power hog just lower your credibility.

I couldn't find this info reading skimming those reviews, but how are they measuring the power consumption? If they're measuring from the wall using something like a Kill-A-Watt, then you have to remember that the numbers are already inflated due to the inefficiency of the power supply (i.e. 300W of DC output at 80% efficiency would draw 375W AC input from the outlet).

And from what I understand (I haven't kept up with PSU tech in a while, so maybe they're a lot better now), PSUs are most efficient when close to their maximum capacity, these reviews are using massive 1000/1200W units, where they're likely well <80% efficient at the loads we're looking at.

Which is a reason why you don't want to get a much higher capacity PSU than you need, because it'll probably use more power for the same load.

[mucat]

Who knows how they did the reviews. But 500W to 750W (or even 850W) is not a wrong purchase IMO.

While it is totally overkill to get a 1000W PSU for a normal machine (I think we can all agree), it is also unwise to get a PSU barely adequate.
Since price between a 500W PSU to 750W PSU is not a big difference, it is better to get a bigger one (with good quality of course).
When down the road you run into problem, you can eliminate PSU as a potential issue right away.

No, they're most efficient near 50% load. The closer it is to 100% load, the less efficient it becomes due to thermal effects. Generally 100% is the least efficient loading.
