How do I know how Many amps are in my 12V rail?

KingJuliusTheGreat · Dec 29, 2014

It says:

100-127V 6A
200-240V 3A

I know this is not what I have to read. But the nameplate with the 12V, 3.3V etc. is facing INSIDE the CPU and I'm not going to remove the case. Is there any way I can figure out what my PSU model is?
Here is my PC model:

HP Pavilion Slimline s5100la

There are a couple different models available for that system you would need to open the system an look to be sure.

Can you see a tag on the PSU with an HP Spare PN? Might help.

Saberus :

It says "HP invent"

Then you may have to remove the other side, or the PSU to read what's on the label.

If this info will help to determine whether to change the psu is it possible that you need to remove it anyway so maybe a good practice exercise?

Not gonna happen. Is there any other way I can figure out the PSU model? Or at least an average on the amps in "HP invent" power supplies?

KingJuliusTheGreat :

If you can't/won't remove the PSU to get these ratings, you're going to need a multimeter. But the maximum input wattage is 600W, based on the info already given. However, per HP the PSU is only 220W. likely the amps listed account for input rush. With 220W I'd imagine you have about 10-15A on the 12v rail max.

I don't think they sell x-ray glasses in the back of comics any more, so no there is no sure way to get the specs.

Well, then is there any way I can figure out the amps average for HP invent PSUs? How much do they usually deliver? Anything ?

bignastyid · Dec 29, 2014

The 220w bestec replacment unit has 16a on the 12v rail.

KingJuliusTheGreat · Dec 29, 2014

bignastyid :

Um, I don't have a replacement. I've never touched that PSU. Is it possible that it still has the same amount of amps?

bignastyid · Dec 29, 2014

KingJuliusTheGreat :

Possible, the original PSU is also 220w

KingJuliusTheGreat · Dec 29, 2014

bignastyid :

Do you by any chance know what is the minimum amps this PSU can deliver?

Saberus · Dec 29, 2014

Minimum Amps is zero, when it's unplugged. If the replacement is 16A, then it's a pretty safe bet the original is 16A as well.

Saberus :

Forgive me, I failed to explain myself. What I meant is what HP invent PSU delivers the less amps. For example: HP invent model:XY123 delivers only D amps.

KingJuliusTheGreat :

This machine may have multiple part numbers for the PSU, but those would be per manufacturer and all would have exact same specs.

So you think it's likely my PSU has 16 amps? Even if it NOT a replacement?

HP does not use spare parts that deviate from the originals in any significant manner except to correct defects. So it's safe to say yes, it has a 16A 12v rail, new or replacement.
