Ok, I'm with you now, apologies for being dim.
tested the resistors with the T7 and they show up as you said they would.

So that just leaves the several shorted diodes, one 600V rectifier diode (1N5406), and the smd ones (LL34)

Thanks again for clearing things up for me....

OK thank you, that's a huge help already, I was thrown off by the black ring at the end.
And don't worry, that's exactly what I'm doing.

And I just powered the relay and got a click on and off. So I was wrong there.
And I assure you the resistors are short, and they came from the negative DC pin of the bridge rectifier.

There are diodes on AC pins of the bridge rectifier both seem fine,
Plenty of resistors too,...

OK so after some more work, the question I'm left with is how to determine the voltage rating of the smd diodes, as they have no markings, they are 5mm long by 3mm wide.
Ideally without probing it when connected to mains.

Also I'm having trouble identifying these resistors as I'm unsure which way to read the colour code.
The left one is either 28M or 16.8k.
fairly certain the right ones are 10k, but the black tolerance band is confusing me.
fairly sure there all 2W, they're 17mm long, 6mm diameter, 2mm wire, am I right?

Just starting out in electronics repair and teaching myself as I go.
I have here a Corsair RM650 ATX PSU, which I'm treating as a learning project that if successful may be used in my PC.
Fuse was blown, probable power surge from lightning, followed the circuit and found, a dead relay and all the diodes and resistors around the bridge rectifier shorted. Rectifier and MOSFETs seem fine on the LCR.
Also found these tiny diodes on the other side, a few shorted, the rest seem fine. But they're not all marked as Zener on the pcb. So I'm unsure what these should be replaced with....
