Make a Switching Mode Power Supply? (SMPS)

Ummm, no.

Have it repaired by a competent tech would be one solution. Pretty hard to find, as most are just glorified parts changers.

Information to pass on to the tech:

I've been searching the internet, and it seems a the R20 resistor on the circuit board, (Don't know if it's on the input base plate, or the stabilization base plate), is one component that fails.
It is a .22 Ohm resistor.
(That's point 22 Ohm, not 22 Ohm)
A competent tech will know what voltage range, and tolerance range, to use for a replacement.

The second component that seems to fail is one, or all four, of the power MOS-FET's.

(IF I understand correctly, the 07N60C3 MOS-FET's, are Infineon SPP0760C3 unit's.
Again IF I understand correctly, the Hitachi 2SK3234 may be a replacement)

The power supply used was made by Delta Electronics. It was made in Japan. The model number is DPS-197AB.
Sony's Part Number is 1-468-878-11.

The pinout of the 18-pin ATX main power cable connector, (CN1), according to my sources is;

Pin 1 - Orange - +3.3 Volts
Pin 2 - Orange - +3.3 Volts
Pin 3 - Red - +5 Volts
Pin 4 - Blue - Power Signal
Pin 5 - Green - PS-ON (With ground power source on)
Pin 6 - White - Fan -(Motherboard fan)
Pin 7 - Pink - + of Mfan (Case fan. same/same)
Pin 8 - Yellow - +12 Volts
Pin 9 - Yellow - +12 Volts
Pin 10 - Black - Ground
Pin 11 - Black - GRD
Pin 12 - Black - GRD
Pin 13 - Black - GRD
Pin 14 - Purple - +5 VSB (+5 Volt Standby. The usual 5 Volts)
Pin 15 - Gray - Power Good
Pin 16 - Black - GRD
Pin 17 - Black - GRD
Pin 18 - Yellow - +12 Volts

The PSU (Power Supply Unit) case, indicates 197.7 Watts is the maximum rated amount.

1) The 3.3 Volt power rail can handle 8 Amps (26.4 Watts)
2) The 5 Volt power rail can handle 7 Amps (35 Watts)
3) The 12 Volt power rail can handle 14 Amps (168 Watts)

Total is more like 229.4 Watts.
(Of course this power supply, probably only has a maximum sustained efficiency of 80 percent)

To you:
A computer only uses the power it needs, and NO more. If there was a way to hook up a 1000 Watt power supply, it wouldn't hurt the computer.

IMHO, a tech will not be able to substitute the circuit board, and components, out of another power supply, and be able to fit it in the power supply case, that fits in the Sony Vaio VGC M1 All-In-One computer.

The size, and shape of the metal casing, is a Proprietary item for the Vaio VGC M1, as well as the 18-pin ATX main power cable connector.
(As you are already aware about the 18-pin connector pinout)

(Proprietary meaning made for THAT computer)

This would mean using an external power supply. Something that a professional tech is not going to approach.
Liability issues dealing with safety.

IMHO though it is a feasible approach, IF, the power supply has a metal case cover of solid design, that allows a space between it, and the replacement power supply's case.

Power supply's cases have ventilation holes in them.
What do you suppose would happen if a toddler, inserted a metal rod down into one of those ventilation holes?
Bad shock to Fatal!
Also if water were accidentally spilled on the power supply.

There would have to be a metal casing that allows an air space between it, and the replacement power supply's case, so the replacement power supply would have adequate ventilation. Would also be a safety guard.

I have also searched online, and I also concur that the Delta DPS-197AB power supply, is as rare as hen's teeth.
(Chicken hens do not have teeth)

I did see where someone on Ebay UK had one for sale, but the listing is over.
I saw a Japanese auction website that had one also, but it's listing was over.

I also saw where a person on a forum had two for sale. (Long over with)
Indication was a bad power supply, but the final diagnosis revealed the motherboard was bad.
(Food for thought)

{I also saw where a motherboard was offered on Ebay}

To conclude:
MAYBE, there is a tech that will outfit an external power supply.
Not a very aesthetic approach, but a viable one. (IMHO)
The tech will remove the 18-pin connector from the power wires of the original power supply, and insert the power wires of the replacement power supply into the 18-pin ATX main power cable connector.

Or perhaps an individual will again offer the power supply


DO NOT open the power supply yourself!!
There are Electrolytic Capacitors used in the power supply. (Input Stage, and Output Stage. They are used as Filters)

An Electrolytic Capacitor slowly builds up a charge, then releases it, All At Once.
They can hold a charge, once removed from power, for weeks, months, and sometimes over a year.

IF, your finger's touch the terminals on the bottom of an Electrolytic Capacitor, the charge can be released to you!

IF, your finger's touch, and complete a circuit that one, or more capacitors are in, the charge can be released to you!

Bad shock to FATAL!

There is a proper way to discharge a capacitor.
I will not list it.

Repair is for a qualified, competent repair tech.


The above link, is to show you some of the Electrolytic Capacitors used inside a Delta DPS-197AB power supply.
The link is not translated on purpose.

Scroll down to the 3rd, and 4th photo. That large Black object that looks like a Can, and has - 4742AW on it, is an Electrolytic Capacitor.

This one has enough power stored to put X's in your eyes]

Of The 4 Connections On The Motherboard Is A Specific Pin Connection Critical Regarding Which One The Internal Main Hardrive Connects To?

According to specifications listed on Sony Vaio Support, the Vaio VGC-RA840G desktop computer uses a SATA harddrive.

[Left-click on Marketing Specifications]

If you have four SATA headers on your motherboard, you can plug your SATA harddrive into any one of them.

The beauty of SATA is that once you plug into any SATA header, BIOS will find the harddrive. Doesn't matter which SATA connector. (Connector on a motherboard is referred to as a Header)

I want to upgrade the motherboard in my Sony VAIO VGC-RC110G PC Desktop. Is this possible or does sony use a nonstandard configured motherboard?

I have only worked on one of these Sony desktops, and it is really very proprietary, where you would be better off buying a new case to install a new motherboard in. The sony looks really slick, but everything about it is odd: The power supply, the cooling fan for the cpu, etc. It would be a lot easier to save what you can and move it to a new project!

Need the motherboard layout for this board out of viao vgc-rc110g

You will find as with Dell that the motherboard etc is all custom & you cant upgrade it yourself, you have to go through Sony. I am not 100% on that but that has been the case with many branded PCs i have seen.

Can you not open the case? This usually voids the warranty but if you were intending to replace parts then it would likely be voided anyway.
