I'm sorry, but I don't understand what you are saying. If you want a power supply calculator, try the one in my signature.

For you hardware it gives:

Recommended PSU: 306W (99W on +3.3v & +5v rails) for:
-1 x Motherboard without onboard devices
-6 x Fans (including PSU fans)
-4 x Memory (128MB DDR)
-1 x Graphic Card
-1 x PCI Sound
-1 x HDD
-1 x CD-RW
-1 x Keyboard
-1 x Mouse
-1 x PCI Modem
-CPU: Intel P4 3.0D GHz 0.13 ?m ?PGA478 @ 1.525 V with HTT

The 24V 206W (306-99) requirement gives 17A.

If you want my experience, buy the 465. The Antec 430 will handle what you have now but if you add a better video card you may run out of juice.

watts = volts x amps

+3.3V x 28.0A = 92.4W
+5V x 36A = 180W
+12V x 20A = 240W

Total: 512.4W

However, the entire supply has a limit of 410W on the above voltages. That's why you can't make a decision based on Watts alone.

Enermax is available both on-line and through computer stores.

Hi, again all there

I have tried all day :fear:, I'm sure i don't know how to PSu calculator, have some questions: :confused2:

A. is it correct my done math of psu calculator? and why different them of amps? how much most important of amps (+3.3v,+5v,+12v) (see below)
My PSU calculator:

EnerMAX EG465P-VE FCA
3.3V @ 0.3A / 35A
+5V @ 0.3A / 35A
+12V @ 1.5A / 33A
-12V @ 0A / 1A
-5V @ 0A / 1A
+5Vsb @ 0.1A / 2.2A
---------------------
+3.3V & +5V=200W
Total O/P=460W

Calculator PSU:
+3.3V*35A = 115.5W
+5v*35A = 175W
+12v*33A = 396w

total = 686.5watts---No way! :shocked:(this is too much)
3.3v + 5v = 290.5 watts

686.5@70% = 480.55w

686.5@30% = 205.95w

686.5@50% = 343.25w


So, the 396 watts from the 12v rail and its running @ 70% = 227.2W,
now 396 watts @ 30% 118.8W, and 156 watts running @ the optimal 50% = 198Watts.


--AND--

Antec Truepower with blue LED 480
+3.3V @ 0A/30.0A
+5V @ 0A/38A
+12V @ 0.8A/22A
-5V @ 0A/0.5A
-12V @ 0A/1.0A
+5VSB @ 0A/2.0A
-------------------
+3.3v , +5v & +12v = 410 Watts max


Calculator PSU:
+3.3V*30A = 99W
+5v*38A = 190W
+12v*22A = 264w

total = 553watts
3.3v + 5v = 289 watts

553@70% = 387.1w

553@30% = 165.9w

553@50% = 276.5w

so, the 264 watts from the 12v rail and its running @ 70% = 184.8W,
now 264 watts @ 30% = 133W, and 264 watts running @ the optimal 50% = 69.3Watts.


Can I choose Antec TrueBlue 480 watts? is it OK? :confused2:


-------------------------------------------------------


B. is it right my done math of PSU calculator? how much one choose my good psu?


My sign:
MSI 865PE Neo2-LS

Antec PLUSView1000AMG Case (no power supply)
Sound Blaster live 5.1 card
keyboard and mouse (wireless)
USB S-bracket
firewire card IEEE 1394



My siguration all system to caluclator
from http://www.jscustompcs.com/power_supply/ about 475 Watts


475 watts --> 475 + 475*30% = 617.5 then 617.5 - 617.5*30% = 432.25w as same as
475 - 475*30% = 332.5 then 332.5 + 332.5*30% = 432.25w...enjoy!


other from http://www.adecy.com/psu/ about:

Recommended PSU: 425W (143W on +3.3v & +5v rails) for:
-1 x Motherboard without onboard devices
-8 x Fans (including PSU fans)
-4 x Memory (128MB DDR)

with almost every thing in your box running of the 12v rail

make sure the 3.3v is over 28a

and then get the biggest 12v amps value going

in your case the enermax you listed

but if you have that antec 430 now why do you need a new psu

i would have thought thats fine

Sorry I forgot, I've tried calculation at http://www.adecy.com/psu, and I got I need
423 W, does it mean I need a PSU whose features give 423 following your calculation or what?

Thank you, I can not understand what all these numbers mean

:idea:

Trust me when I say that ThermalTake and PowMax are probably not the way to go. I don't know about Vantec, but I'm using an Antec True550 fine.
