[Susquehannock]

Typed in my system specs and the calculator came up with 298w.
Guess this PCP&C 425dlx isn't getting much of a workout.

Everyone knows that Enermax makes very good Power Supplies.

The first one, an excellent and very powerful older design 550W, designed for P3 CPU's, with massive +3.3V and +5V rails, has only +12V@14A and is almost useless for todays computers. I believe that this model has been discontinued, as it no longer appears on the Enermax website.

Almost every major name brand of power supplies has similar "older design" models in their current offerings. We must learn to identify and avoid them. This also shows how using total wattage, even when dealing with high quality, name brand power supplies, is a harmful and misleading method of choosing a power supply and also shows the danger of trusting "power supply calculator's."

The calculator in #2 and #3 links are really good, only 5watts difference for me... but that "NAN" crap from the calculator in link #1 is for the birds.

I get a total of 260w of power usage from said rig in my sig so im sure that Qmax 350w generic psu isn't even breaking a sweat.

[Susquehannock]

Yeah, that 1st one is outdated. The 3rd one is my favorite.
Just calculated my system specs again and it only comes up to 317w - over 100w to spare

It was written by an EOC member with input from all of us &

it is the ONLY PS calculator that I recommend!

Wow, mad props to whoever it is.

It so simple to use... a caveman can do it.(geico commercial)

From the PS Guide:

To see why total wattage should never be used to select a power supply, but that the properly allocated wattage is very important in selecting the proper PS, please click on the following link to the ONLY "Power Supply Calculator" that I can & DO RECOMMEND, provided by & constantly updated by "mnemonik23": http://www.extreme.outervision.com/

We all thank you "mnemonik23"!

That first one is kind of useless now, but that last one is gnarly. The only thing it's missing is the overclocked CPU wattage! This one will give you that, but you have to input the stock wattage, because the defaults are dated: http://www.benchtest.com/calc.html

Very nice find

Thanks davidhammock200

btw, I was working on CPU overclocking thingy for some time and now its almost ready just need to finish with TDP for some AMD CPUs and will release the 1.1 version next week!

The eXtreme PSU Calculator v1.1 will contain 300+ processors!

Thanks to AkXb70 and his amazing job with putting together the CPU list: http://forums.extremeoverclocking.co...d.php?t=131527

You are most welcome & I'm looking forward to ver 1.1, especially the OC'ing calculations.

Ditto! ^^^

Many thanx for your efforts mnemonik23. :

Guys, if you can help me with some AMD Athlons XP I'd appreciate it so much!

There is a list: http://forums.extremeoverclocking.co...d.php?t=131527 (zip file).

What I need is to gather TDP (Thermal Design Power) for AMD Athlon XP cpus, I'm not very familiar with them. I'm not asking to spend a lot of your time to do a research... if you have some info please share.

Thanks!

[Susquehannock]

That zip file gave a HUGE list of text. Not sure if it's working right for me.

Here's a start ....

AMD XP Family:

Model 6 .......
1500+ = 60.0w max - 53.8w typical
1600+ = 62.8w max - 56.3w typical
1700+ = 64.0w max - 57.4w typical
1800+ = 66.0w max - 59.2w typical
1900+ = 68.0w max - 60.7w typical
2000+ = 70.3w max - 62.5w typical
2100+ = 72.0w max - 64.3w typical
http://www.amd.com/us-en/assets/cont...docs/24309.pdf

Model 10 .....
2000+ = 60.3w max - 47.4w typical
2200+ = 62.8w max - 49.4w typical
2400+ = 68.3w max - 53.7w typical

Just wanted to point out that I configured my PC, and I added the most items I figured I'd ever need, and it still only came out to 400 watts fully loaded to the hilt, 4 hd's, 2 optical drives, 5 fans, etc, fan controller etc.

I've got an Noisetaker 420 2.0 so I even went a little over kill for a maximum possible configuration. I doubt I even approach 350 watts right now.

edit:

If you had Dual 6800 ultra's in SLI though, 236 watts alone, yipes!
