A question about my PSU

blindartist · August 15th, 2007, 12:08 AM

Hey guys, i know this isnt the right place to post this but it didnt quite fit anywhere and i figured overclockers know their PSU's pretty well.

So, i wanna buy a radeon x1950 pro, it says that it requires a 450w psu with a 12v 30amp rail, i have a SafePower 465w psu, but i cannot for the life of me find if it has a 12v 30amp rail, how would i go about finding out, or does anyone know if it does?

Thanks for your time and help guys.

Best Regards
~Dave

Please post a picture of your PSU voltages table.

Or tell what it says in its box.

I found this one online, its a little blurry but hopefully will help

it says that 450w with 30amp on 12v rail is "recomended", if im reading this chart thing right(which im probably not) mine only has 26amps on 12v right? would it sitll work?

Looks like the 12V rail you have or the sum of all of them wont cover all the 30amps you need, i do not recommend using a 1950pro with this PSU. I could be wrong, sometimes they use the lower fluctuation point ( like +/- X %), but still its not a good idea.

oh well that sucks, really was hoping not to have to buy a new psu, well thank you for your help.

use a Everest to see your voltage
than you will know is that psu enough for you PC

software and bios voltage meters are just ballpark figures their not even remotely accurate so theres no point, guess ill just have to go shell out the money for a new one, they couldnt just make them to work with everything, that would be to easy.

lol
do you know that your mbo have sensors lol they measure volts but never mind
if you are buying new psu watch out for real power
because some firms put something like this 500w +150w and they write it like 700W or something like it
and take a branded PSU

Yea i do know that but if you ask anyone that really knows about this stuff they'll tell you the sensors arent very accurate, youd need an actual good multimeter to accurately measure the voltages, oh well.

Guess ill shell out the 90 bucks and get a decent untra psu, seems to be the best deal i can find for a good psu

you cant measure real power if you only connect lines on multimeter you need to see voltage drop down from aprox. 12.3v to lower volage like 12.01 or 11.92
you need to plug on mbo and to cut some isolation from wires or to screv around with pins so you can measure it correctly and that is long way to do it

i get around 575W from my psu
