Dell Precision T3600 Power Supply (PSU) amber light issue

I have to 2 Dell Precision T3600 computers that only power on after the second try.

If you press the power button first time: the power button get's a amber light & 1 3 4 diagnostic get a flickering amber light. 

If you turn the computer off and press the power button again it will turn on and work as normal.

I have been able to diagnose that the PSU is the problem.

I would like to know if I can continue to use these desktops in their current state? Are there any potential consequences / risks involved?

Also can the PSU can be repaired? If so how?

Thank you in advance.

Manual indicates it may be PSU cable related:

1- Blink
2- Off
3- Blink
4- Blink

PSU Cable Failure

All PSU cables may not be properly connected to system board. (PS_ON asserted, missing a main power rail)

Did you try to reseat the motherboard's PSU cable(s)?

No, I admit that I didn't try that.

T3600 is hot swap psu so I just put another "working" psu in the machines and then they did go on so I assumed the issue was with the psu units itself and not the cables. 

But I'll give it try.

I reseated the cables of tboth PCs and there is no change in the situation.

So I still think it's the PSUs.

Does anyone know what the possible consequences are for continued use  like this?

Because I don't want to buy a new PSU if it does sort of still work?
