  1. ok, i didnt know where to post this, so here i am in Other Hardware..

    i have a 250watt Bestec PSU (im not even sure if thats a cheap brand or good brand) and is it possible to check how much of that 250watt my PC is actually using?

    I am planning to upgrade my PSU.. but before i do that , iwant to know if i really need to.. .

    You can find out here what your power requirements are.

    Here you'll find recommendations for psu's.

    At a guess Bestec is probably a cheap brand.

    thanks mr iron duke.. the first link ses with all the stuff i clicked on.. im using 258watts.. n i only have 250watts.. and i read on the 2nd link that most companies over rate their PSU's.. so if in reality.. my 250watt is only say... 175watt.. and its generic.. so prolly a 150watt..

    how come my PC is still running and alive? harr.. going to get a new PSU tmrw lol

    I have an Enermax 365V which has been running faultlessly 18 months. So this would be a good choice for me.

    The PSU calculator you were linked to gives you the absolute peak consumption possible. This will never, ever happen in reality. You cannot have all your drives spinning up at the same time while the CPU is crunching away on a very demanding calculation while the video card is rendering a 1600x1200 3D scene in real time.

    If you do not have any issues then there is no point in going to waste your money on some shiny thing with LEDs and six fans.

    You can buy one of those power meters for home appliances and put it between your computer and the wall outlet. You will have to take into account the ineficciencies in power conversion but you will get a rough idea what your PSU is using = supplying to the computer.
