Can you increase the Ampere rating of 3.3/5/12V ???

[Bloodstone]

Hello there :)

I would like to ask if anyone knows how to increase the ampere ratings of all the rails. Such as combining two PSU to increase the ampere rating of each.
I found a website that only combines to PSU in one PC just to turn it on simoltaneously.

I have these old PSU with only 14A at 3.3V and I want to combine to increase its ampere rating.

Anyone????

There are several threads around advising how to use multiple PSUs to power a PC. It's not a big deal to do. Try a search here or at PC Perspectives for the threads on this subject.

Thank you :)

About powering 2 PSU in one PC, i've already done that. Is there a thread here that focuses on increasing the ampere of the rails?

Doesn't running 2 power supplies simultaneously to increase the voltage also increase the over all amperage???

The only way to do it would be to open the PSU and find the overcurrent sense then modify it.

Adding another PSU directly (not just using it to run HDD's etc while main psu runs system) is dangerous at best.

Thank you for your reply :)

Do you mean connecting PSUs in series? Actually, for ex. connecting two 1.5V batteries with 500mA will yield 3.0V with 500mA, and when connecting them in parallel will yield 1.5V with 1A. But that only holds true with batteries. I am not sure if it is the same with PSUs.

no, he means in parallel.

series the psu would just shut off or fry.

The only thing that I could say is:

I smell a short-circuit. :D (regarding the idea with PSUs in series. ;) )

Thank you very much :)

I found a website that has an article about linking two PSU in parallel and in series. It says there that when you connect the two PSU's rails in parallel, it will yield to increase amperage and the voltage will ramain the same. He also connected the two PSU's rails in series mode which results in increase voltage but the amperage remains the same.

But the problem there, he used to AT 250W PSU instead of ATX PSU. And also, the article was made in the year of our Lord 2001.

What do you think??? Please give me your comments and any violent reactions with this.

Lo foks.. :)

parallel would work if it wassent for its a elektrik transformer, and not a iron, setting them parallel would fry both PSUs, talking smoke becouz if one of the PSUs runs 12,5 and the outher 12 the last 0,5 volt would be pulled out of the second transformer and fry it...

what u need 2 do is buy a redudants curcet PSUs like 2x460 watt. dont know what this costs but a lot cheaper then blowing up ur hardware.. :)

i know my english i kinda crappy (live with it) :P
