I currently have 430 watts and im quite unsure about the stability of my computer. I want to make sure i have enough power.

ill try to list everything i remember:
amd athlon x2 BE-2300 (it says energy efficient 45 W)
seagate 320 gb hard drive, not sata (there are ribbon cables)
WD 1tb caviar black (new, i think this needs more power but im unsure)
geforce 9600
and a few extra fans

i dont know if im forgetting anything

I was experiencing weird things with my monitor. I checked temperature readings and they seemed fine so im guessing it might be due to a lack of power
Thx

Also, my computer freezes and i cannot move my mouse. I think the hard drive makes weird noises too when it freezes. I hope this isnt part of a bigger problem bcuz i just had 2 hard drives fail on me recently and i dont want this new one to do the same.

You might take a look at Thermaltake's Power Supply Calculator for a general idea of what you will need.

Keep in mind you should get PSU's that are a bit above what your system requires. So, for instance, if your PC requires 500W, get a 650W just for a little breathing room. Those two calculators can have vastly different results. I put in my current setup (found in my profile page) and one gave me 450W and another 965W. As for your other issues, how old are the hard drives? Most drives last about five years or so before they begin to fail.

is this a recent problem that just started? or has it always done this since you built the system, or only after adding a certain component? if its a recent problem, and it didnt start after you added something, then its probably not a lack of power, but something failing somewhere. If its always done this or started after you added a component, it may be the power supply, that does seem kind of a weak supply for that system, but I would try those power supply caculaters first to be sure.

the seagate 320 gb hard drive is maybe 3-4 years old. it runs with no problem except it has 1 bad sector and it has caused me an annoying problem but i dont wanna get into it.(ill save it for when i am 100% my computer is stable)
Last year, i had bought 2 seagate 500gb barracudas. Both had the really bad firmware issues. I updated both of them however one failed with about 1700 bad sectors i think around december, the second one had a ntfs.sys error around march maybe. I bought the wd 1tb caviar black so i could back up my data before trying to fix the screwed up hard drives. So far, there is no problem unless i have a specific fan plugged in. This fan makes noises atleast once a day which sounds like a really loud VRRRRMM sound. I have to stop the sound by tapping the case on which the fan is mounted. However, when i installed the new hard drive i got weird problems with my computer. At first the screen would go black (not off) or the monitor would suddenyl become all yellow or all light blue. I unplugged the fan and the problem stopped. I am not sure if this is a coincidence.

speed fan shows good temperatures for everything except my video card which is at 55 C so i doubt my computer is overheating.
I know the caviar black is made for speed and performance so i thought it would require lots of power. However the transfer rates are horrible which they shouldnt be.

!!!!! PS- If you plan to post something about how to fix my 2 hard drives or my slow caviar black, I started a separate thread with those problems (and many many many other problems). I have only started 2 threads so you can find it easily if you wish to help.

Thx. I was surprised at how fast everyone replied!

have you tried the power supply calculators yet?

Unless the power supply is bad, it is more than enough.

Video 60watts, processor 45watts, misc (mobo/mem/HDs) and total draw is still ~150 watts.

ARGHH, ok sry but i went under my desk to plug in some speakers in the back. I came up from under the desk and my monitor was black. The keyboard and mouse was unresponsive. Just when i thought i had backed up my data and i was at safe place, there is a problem.
I am not sure if this was related to my plugging in the speaker because it happened by itself once when i left my computer to reformat a bad drive (the one with 1700+ bad sectors).

I tried the first calculator and there are a lot of stuff i dont know about.
I tried the new egg calculator but there was some stuff i have that arent on the list.

Thank God its spring break or i would go crazy. Right now im on the brink of going crazy. I have no appetite and im really tired.

As dpunisher said, unless your power supply is failing, you have plenty of power.

You mean now, even if you restart the computer, the screen remains black? If so, this isn't due to the hard drive. A computer will still turn on and display the BIOS without a hard drive.

EDIT: How many amps are on the +12V rail?

The screen turns black at seemingly random times. The computer works fine, it boots fine, i see my desktop there are no problems then everytime when i look away then look back the screen is black and i can do nothing (or atleast i think i cant do anything). I dont know when its gonna happen. This started happening ever since i hooked up the new hard drive.


"EDIT: How many amps are on the +12V rail? "
What? There is a chart on my power supply but im not quite sure what you are talking about

And my power supply is actually 420 W.

Also, is there a way to see if your power supply is failing?

The label should say +12V and then have another number followed by "a" such as 18a, or 24a, etc. You may have multiple +12V rails which would be labeled as +12V1 and +12V2 . If you give us the make and model of the power supply, we may be able to find it out.

You could try the power supply in another computer, or try another power supply in your computer.

hold on, he said he had a 9600 in it didnt he? the nvidia 9600 requires a 300 watt PSU if I recall.

Yes, i said a nvidia geforce 9600. It wasnt on the newegg calculator though.
In speed fan, my video card has a fire symbol and it is at about 55 Celsius. But that is the only thing overheating.

This is my power supply
http://www.newegg.com/product/product.aspx...TC-pr1c3grabb3r
I think its pretty old. On the side of my power supply box, It says 13 Amps under + 12V.

Im too afraid to plug in my speakers lol.

EDIT: I quickly went to the nvidia website for the 9600 http://www.nvidia.com/object/product_geforce_9600gt_us.html . for minum power requirments, one column says 400 and one column says 300. But i dont know the difference between the two columns.
