Remaking PSU
I have Feel ESP -300ATXSP4 version 2.03 power supply. I would like to raise the quantity of amperes on lines: + 3.3 V, + 5V and + 12V. I have photos of this PSU
My configuration: MSI KT4V, CPU AMD Athlon 1700@2600 / 333 (with series JIUHB), 512MB DDR / 333, Hercules 8500LE, HDD 7200 40GB Samsung, CDRW Teac 8x, Live!, Lan
 
You can't increase the amperage handling of a power supply without a new circuit design, new circuit board, new components, etc. I guess it's time for a new power supply. Just state your budget and location, and we can probably recommend some better power supplies for you.
 
I know that I have to modify and to convert some parts, I am not such layman to modify in electronics power supply without interference. Besides this, I have not intention to buy new power supply because I don't have a money. I have a dozen or so damaged PSU's in house, and I have access to many electronic parts. Besides this I got information to strengthen the power output of PSU it was one should replace diode ( the most often n3040) to larger for example 60A, to convert transistors marked "to220" to 2c4070", and electrolytical capacitor to ~ 680uF. I ask about detailed information.

P.S.
sorry for my english
 
You could replace some of the parts you mentioned, but you probably will not be able to find compatible replacements from your damaged PSUs. Also, how would you know that the replacement part works with the rest of the circuit? Changing the capacitor value would change the input waveform and possibly reduce the efficiency of the switching regulator IC of the power supply. Changing the transistors from TO-220 to another package would mean that the new transistor simply would not fit in the holes drilled into the PCB. That doesn't help anything.

It is too expensive and difficult to modify an existing power supply when new, good power supplies are available everywhere. Where are you from?
 
I'm from Poland. I wish buy Chieftec/Sirtec 360W PSU, but I don't have money, therefore i bought Feel PSU. I wish add to my computer DVD and hard drive 20GB, but I don't know that PSU will hold up. I know that is the possibility of enlargement amperage on line + 5V from 25A on 35/40 And and on line + 12V from 10A on 13/15 And without loss of stability. Pictures of this PSU and his interior are on side http://republika.pl/sp1atm/images/

For better pictures or list of elements used with this PSU write to me.

I bought a Enermax EG231P-V (230W), because they was a cheap, but it turned out that it was inefficient ( it turns on for third, fourth activation).

Some people (in Russia or Ukraine) remake PSU's, because this is not difficult (PSU's are simple enough devices and cheap in building).

P.S. If I would have money then I would buy something with Antec TruePower series, but not some cheap Chieftec / Sirtec. In this moment I having Feel Psu ( the best from these cheap in my country) and I'm be afraid that it will stand up oneself something which lay oneself from Codegen PSU ( it burnt oneself, but it did not damage fortunately computer).

I would forget, the purchase of PSU can not rather to be at stake with reason of conversion of standard the power from ATX to BTX ( I would like to do some to work on FEEL ATX a bit and later to alter on something company BTX)

Real power of Feel PSU is a 230/240W, +5V is a 25A, +3.3V is a 14A, +12V is a 10A
 
I do not know your living situation, but is it possible for you to get a job? Buying a good power supply would probably be cheaper and safer than replacing parts inside your power supply. Do not worry about about BTX--if you are willing to replace parts inside your power supply, you can handle adding a few wires and installing a few new connectors. BTX power supplies will not be much different from ATX supplies.
 
!?

dont get him to p*ssy out. building your own PSU? badass. sorry i cant help, czero.
 
;)

It's quite a task to even beef up an existing power supply because all of the circuit components depend on each other so much. Designing a new power supply would be quite an undertaking, but definitely not unattainable. I am in the initial stages of designing one myself. :cool:
