I need a new powersupply for my PC build cuz the last one was too weak.
any suggestions? oh yeah I don't have the cash for high end psu's so make em budget.
 
The CV corsair units do not have a good reputation for reliability.
But, they may not be dangerous.
Do not buy a off brand cheap psu.
A cheap PSU will be made of substandard components. It will not have safety and overload protections.
The danger is if it fails under load, it can destroy anything it is connected to.
It will deliver advertised power only at room temperatures, not at higher temperatures found when installed in a case.
The wattage will be delivered on the 3 and 5v rails, not on the 12v rails where modern parts
like the CPU and Graphics cards need it. What power is delivered may fluctuate and cause instability
issues that are hard to diagnose.
The fan will need to spin up higher to cool it, making it noisy.
A cheap PSU can become very expensive.

Do not buy one.

The power you need is primarily determined by your graphics card,
Here is a handy chart:

RX580 is an older, power hungry card. 550w would be ok.

If it can be helpful, here is one list of psu quality tiers:

It's outdated, there's a new revision.

idk much about powersupply's
do bv models and br have a difference?

Yes. BV is very bad, BR should be okay if it's cheap enough, better than Corsair VS or CV (if not 650W, as 650W Corsair CV is okay too).
