Can my psu handle it

skootyloops · 16th May 2006, 10:18 PM

ok i am upgrading to a dual core setup but after looking at my psu i am doubting whether it has the power to run my system. the system is going to be an intel dual core 805, 1ide hdd, 1 sata hdd, 1 dvd burner, and eventually a good graphics card. my psu has the following amps on the lines

+5v = 30amps
+3v = 40amps
+12v = 15amps

its a generic psu (bliss) with a rating of 300W

I'd say not, mainly cause its 300w and its generic

crazylittleman · 16th May 2006, 10:22 PM

Which motherboard are you getting?
Alot of new motherboards have minimum power requirements which a 300watt generic is unlikely to meet.

300W + Generic = No.

Upgrade to a ~400W name brand PSU.

for emphasis:

NO!

Many issues, the first is 15A 12V rail, the cpu alone is going to draw 9A+ stock, and 12A+ overclocked, so 12V rail is already maxed out. Brand is obvious, typically a generic will only do 1/2 to 2/3 their supposed wattage and rail ratings , and any more results in unstable voltages, or even catastrophic psu failure (often taking out other things with it). Decent brands have better protection, and the good models are perfectly stable all the way up to what their rated for. And I haven't even got to more complicated issues like group regulation and 20pin psu on 24pin motherboard. Anyways see ocau psu wiki for suggested replacements.

ok what about if i got an a64 3200+ venice that would greatly take the need for power compared to intel away wouldn't it? not should only be using for 1 -2 months after getting a venice

Whats so bad about upgrading your power supply?

DoCsIs · 16th May 2006, 10:55 PM

If youre spending the money upgrading, spend the money on a new name brand psu. No ifs, no buts.

skootyloops · 16th May 2006, 11:01 PM

the bad thing is my budget by the end of next month i will be able to buy a new psu for my system and i will be but im just wondering whether an athlon 64 3000+/3200+ will be able to run on that psu for about a month?

nux · 16th May 2006, 11:03 PM

Only real way to find out is to buy it and see. My guess is it probably will.

This will give you an idea of what sort of Wattage you will most probably need....

No its unlikely to run an a64 3200+ system either. The group regulation circuit will be tuned for a 5V system (p3/older axp where cpu draws off 5V rail), and will not handle modern systems (where cpu and videocard draw off 12V rail). Trying to use that psu will result in the 12V rail undervotling a LOT, and 5V rail overvolting a lot. Only way to fix that is to add more load on 5V rail, which is impractical. Its an easy fix, $65 gets you an antec sp2.0 350w that will run anything you throw at it (except high end SLI of course), that is designed to run modern systems (since has a big 12V rail, group regulation circuit tuned for 12V systems).

lol, with the 'capacitor aging' and 'surge compensation' cranked, apparantly I need a 760w psu to run my system, yet its run fine on a sp2.0 350w.

but the again its the 'extreme' psu calculator so gotta expect that I suppose....

skootyloops · 17th May 2006, 4:28 PM

ok i used the psu calculator and it says my system will only need about 300W to run so its not too bad

I doubt your 'Bliss' PSU can output 300W though.

It is only a guide. I mid range name brand psu should do the job fine. Personally I wouldn't go below 350-380W name brand psu for modern day systems.
