Is there anything specific I need to do when putting my new pcu in. after my old one died all I did was take it out and remove all the cables.
Is it safe to just do a straight swap
 
Solution
Do not use the cables from the old PSU and then re-use them to the new PSU.
Only use the cables that came from your new PSU, as much as possible.
Keep your old PSU cables and new PSU Cables segregated.

The reason why is because, the PSU cables are not standardized connecting towards the PSU side. The male side of the PSU plug connecting to the female socket of the PSU itself will vary PER PSU model (So don't necessarily think a Corsair 500W PSU might be safe to use on a 600W PSU, you might get lucky but its not 100% guaranteed safe to do so). You might connect a live to a ground, and that can result to a disaster when you turn the PSU on. https://www.gamersnexus.net/guides/2702-psa-on-mixing-modular-psu-cables-dont-do-it

If the new PSU is modular akin to the old one and it's not from the same brand or model, then you shouldn't just swap the units, you should remove all remnants of the old PSU(cables included) and drop the new PSU with it's cables. Even if the cables seem intact(and the unit's are absolutely identical) I'd still advise on a swap.

What are the make and model of the PSU's? Mind sharing the specs to your system in question? You might be suffering from some other issue if your PSU fired.

And yes, you can re-use cables that didn't come from the PSU such as the SATA data cable, as they're standardized on both ends. You can buy more if you're lacking to connect additional SATA drives. Just don't mix up modular PSU cables, keep them in the PSU box that they came with or it'll be a nightmare/additional hassle figuring out which PSU plug came from what - especially if they look similar.
 
Solution
Sata data cables are fine to reuse.

Remove all old power supply connections and use the ones that come with the new psu.

What was the make/model of your old psu, and what is the make/model of the prospective new one?

Buy only a top quality replacement, or your are risking repeating the failure.
Worse, a psu failure can damage all of your other parts.
