Question How Do I Know Which PSU is Needed for the Motherboard?

[alnsmthe000]

I'm building a WinXP-based PC using an ASRock 775i65G R3.0. I haven't decided on a PSU for it yet, but the way this was told to me was that I could use a modern one for this MB.

If I understand it right based on the specs, these are the connector ports

• 20-pin ATX
• 4-pin 12V

Does this determine what PSU can be connected to it?

The motherboard connectors should be standard.

And hardwired PSU's connectors should be a direct match.

However, modular PSUs may have connection cables that do not necessarily match. Meaning that any given modular PSU will work with its accompanying cable(s) but using the cables from other PSUs will not work. Do not mix and match cables between modular PSUs.

FYI:

You can easily find other similar links and explanations.

Start with the motherboards User Guide/Manual to check the connector pin-outs. Do the same with the PSU(s) being considered.

Any mismatches will need to be figured out and resolved before plugging in any connectors.

Before picking a PSU also read the following review from this Forum:

Double check everything.

Most modern PSU are on "24 pin" main connector, but often have 4pin of that be modular. The 4 pin CPU power would be commonplace with pretty much any PSU.

With a PC of that age you will also want to be sure that there are Molex style connectors as well as SATA, as IDK if you may have to use IDE drives with that setup?

Way to expensive for a 14 year old system. Do you have a link to the webshop?

What CPU and GPU is in the system?

That's taking it back, for sure. I would consider the absolute least expensive non-housefire quality PSU you can find. Everything is inflated for Christmas right now, so if you can, wait into January before purchasing.

Yes.

Yes.

I know that's literally a yes/no question that he gave, but for practical reasons, it would be helpful for us to have the link.
