Hello there !
What are your basic needs and requirements ? Is it just hardcore Gaming, or some other work as well ? But nonetheless, you shouldn't be skimping on the PSU, since this is the MOST important component of any RIG/PC. Which PSU MODEL are you currently using ?
Those PSU Models which you have listed, aren't that much good, IMO. Since they fall under the low TIER category of PSUs,
if I'm not mistaken. Entry level more like. Always go for a high-quality PSU, if possible. I'm not saying those are bad power supplies, but please kindly have a look under these links. Some List of power supplies have been listed, categorized under different TIER.
I would personally recommend going for TIER 1-2 power supplies, if possible. Else, any decent high quality 600-650 Watts PSU should be sufficient for your RYZEN rig. Look under the
TIER B BUDGET list of power supply units listed under this thread. Are those models available near your region ?::

Also, apart from this. I would just like to point this out, as a side note. Not directed towards you, but I've seen a a lot of peeps actually SKIMP on the PSU. And most importantly, many aren't even fully aware that WATTAGE number alone means nothing when it comes to any power supply.
The main concern is the "quality" of the power, the quality of the components used/CAPS, as well as the total AMP drawn on the +12V RAIL (output), the efficiency under load, "ripple suppression", among other factors.
The total wattage number of any PSU is
not always really the most important deciding factor, primary concern is the 'quality' of power it produces, and the total capacity of the 12V source etc.
Though how the rails are laid out does not affect that much, i.e. single/multiple +12V rail PSUs. Multi-rail PSU can be mildly better, especially with high wattage unit, but it won't have any impact on your performance, however, it can provide an extra layer of safety in case you get a short circuit. A multi-rail power supply has OCP on all +12V rails, ensuring that your PC components stay alive, if a problem like a short circuit occurs.
A cheap generic/standard low-end PSU is prone to failure soon, than the units made by reputed brands like SEASONIC, Corsair, BE QUIET, EVGA Supernova, PC Power & Cooling, ANTEC (except
earthwatts series), XFX, Super Flower, OCZ, just to name a few.
The OEM also matters a lot, instead of the actual PSU brand.
I've seen PSUs labelled as 1K watts, but in actual real world scenarios, they can hardly pull 400 Watts from the wall, even under full load.
I've always given the topmost priority to PSU when building any RIG, and I mostly go for Tier 1 and/or Tier 2 units, because we know a TITANIUM/Platinum/Gold PSU is going to be much more efficient under 50% load, than a bronze/silver or a generic 80 plus certified PSU. But the exact Wattage requirement still varies from system to system, and if we plan to Overclock the GPU/CPU, then the PSU should have some headroom as well.
