Whats the lowest watt PSU that can handle my second rig?

post #1 of 10
Thread Starter 
This PSU I have on Undormant Downloader (you can check in my profile) seems to have problems. I installed a 450Watt one I have but well 450W is kinda too much. Its my 24/7 PC after all. I was wondering if I could buy a less Watt PSU than the one I have but I donno if it will handle it. Can anyone help me?

The thing is, if you go under 400W, all PSUs are crappy ones from unknown brands, go check newegg, when it comes under 400W, they have mostly poor rating.

why would you want a less powerful PSU than the one you have? The rating on it just says how much it can handle, not how much it constantly draws.

Yep. You could have a PSU rated at 5000w but if your computer only needs 200w, it will only draw 200w.

Well according to the calculator it seems it draws just a little more than 300Watt at full load so it seems going down it out of the question ^^''

So it means that I made this thread for no good reason huh.. Well sorry for wasting your time people. I did not know that it shows the peak. I thought that no matter the setup of the PC the PSU would draw what it says.
