Power Supply Question

by sfig1st / May 7, 2007 10:30 AM PDT

Hi, I just recently purchased a new computer with some "higher end" components (I think) which obiosly requires more power. Without getting into detail with my setup and calculating watts is there programs that will tell me ho much power im using?

I have Speed Fan which I think should tell me how much power im using, I just don't know how to calculate everything up.

Do I want the total for Vbat (in Speed Fan) or somthing?

This chart would help if I did not feel that im using more power than this chart estimates. I also am wondering how I can find out the highest reccomended # of watts I should be using. I remember when buying my computer, I remember hearing that I could just get by (or somthing close to that) with this upgraded power supply...

Here is my Setup:

Intel Core2Duo CPU E6600 @ 2.40GHz overclocked to 2.6 GHz + HeatSink & Fan

Two sticks of 1.0 GB DDR2 667 MHz

Windows XP

Radeon X1950 XT GPU + Fan (which is built in)

ATI T200 Sound Card

250 GB Hard Drive

2 "Super Multi" CD/DVD drives

Gigabyte 965P-DS3 Motherboard

Keyboard + Mouse

Fan at the back of Case and a fan in the front of the case

Since you've listed a lot of hardware there and you're going to be overclocking and you appear to be a gamer, I'd go with 500+ and a "GOOD" 500 or 550 watt PSU which should supply a quality and even power source.. When the processor and multiple drives are all running you want something that will do the job.

Hope this helps.

Would a: ENERMAX 535W SLI READY ATX POWER SUPPLY 20/24+6+6 do the job?

also while I was browsing the power supplies I notice alot of tables like this one:

AC Input: P-VE : 115/230 VAC, 50-60Hz, 12A/6A, Manual Switching
AX-VE(G): 230 VAC, 50-60Hz, 4.3A, Active PFC
AX-VE(W): 100-240 VAC, 50-60Hz, 9.5-4.0A, Automatic Switching
DC Output +3.3V +5V +12V1 +12V2 -12V +5Vsb Total Power
32A 32A 22A 22A 0.6A 3A 535W
170W 408W(34A) 7.2W 15W
512.8W 22.2W

Can you explain what this means?

Also is there anyway to see how amny watts my computer is using? (progrmans etc.)

Answer Already Given..

The chart I supplied earlier gives you a basic idea of how many watts are capable from the system.. At any one time, depending on any changes in the hardware and the amount of "work" the hardware is doing will change the wattage used either up or down.

As to which specific power supply you choose, that's up to you.. Google is a great tool for looking at reviews. has a number of good reviews as well.

As to the specifications of the power supply you've listed, sorry, I'm not electrician.. Others here are much better in that area than I am.

Hope this helps.
