Power supply help please

[Decypher]

Okay so i was just wondering. Right now my computers PS is a 300w.

Currently it is overheating and my computer automatically shuts off.
I have a 400w power supply sitting here. And i was just wondering am i able to switch them? Would the 100w difference do anything? As long as they are both set on 115v would i be good to go?

Any info would be great!!

Hey Decypher,

It will probably make the system more stable. How many amps do both PSUs, have on their +12v rails? You can check by reading it's label.

Also, what are the specs of your system?

 

[Decypher]

Thanks for the welcome


The 400w says +12v / 10A
And the 300w says+12v / 14A

PC specs are:

Gigabyte motherboard
1.250gb RAM
Pentium 4 2.4ghz
Radeon 128mb Graphics card
140gb Hard drive

Hope this helps.

The 400w actually has less power on the 12v (10 amps vs. 14) Do you know the exact card in your machine?

I wonder if those power supplies have more than one +12v rail. Especially that 400w, unless it's a very cheap one.

Decypher,
See if you can find more than one +12v rail, on the label. It would say something like +12V1 and +12V2.

The 400w says +12v / 10A
And the 300w says+12v / 14A

For the 400W, is that the only +12V rail you see on the label?

 

[Decypher]

Yea thats the only one. Its just a crappy PS that was given to me. I have another also...

Says:

Output 450w MAX

+12V = 15A

And thats also the only +12v


I just need anything because the one im using now is screwed. I had to take off the shell to the PSU and the side off my computer and have a massive industrial fan blowing on it lmao.

Computer doesnt shut down what so ever with the fan. And it only shuts down on me when i am playing an online game.

i prefer to use 550w, so they can hold all your hardware
