Psu advice please
That’s a very astute observation, and you’re likely right about the PSU being the culprit. Here’s what you should do:
1. **Immediately RMA (Return Merchandise Authorization) the PSU:** The fact that the noise started after changing the PSU is a strong indicator. Don't wait to see if it dies down – a failing PSU can damage other components.
2. **Document Everything:** Keep records of your purchase, the new PSU, and your communication with the retailer.
3. **Test in another machine (if possible):** If you have access to another computer, test the PSU there to confirm that it is indeed faulty.
4. **Don't try to troubleshoot further:** Unless you are extremely experienced with power supply diagnostics, attempting to diagnose a failing PSU yourself is risky and could lead to damage or injury.
Actually, a single strong rail is usually favorable for gaming cards.
Multiple rails are only meant to be a form of protection. There are no power benefits from it really.
This is pretty much everything you need to know about multiple vs single rail power supply designs.

Yep, as Blackbird is telling your this is not uncommon on that PSU. We've seen more than a few of those.
If it were ME, I'd probably RETURN it and go with a different PSU like the EVGA G2 or G3 750w, or one of the Seasonic Focus, Focus plus or Prime models.
Problem is I've got custom cables for corsair rm series. Any advice on what corsair psu would be best or should I try return cables and get a different brand cpu?
These are cable modem cables designed to be compatible with the RM or RMI series.
If you’re limited to those options, you'll only be able to use them with the RMi and RMx series units which are designed for modularity. If you prefer not to risk a replacement unit from the same series, then your sole alternative would be to return the cables and select a different brand or model of power supply.
What is your graphics card’s make and model? And it's important to note that some power supplies are recognized to cause coil whine problems when paired with certain brands and models of gaming cards.
Is the power supply unit linked correctly? Please switch it over from the multiple-rail setting to the single-rail setting.
