If you don't have the ability to assess/test the cables yourself it is hard to say really, from what I've seen of these type of sellers they're mostly Chinese/Hong Kong sellers offering you generic cables with a specific pinout. It might be fine, but if they make an error (which e.g. could be during shipping, the pinout, or knowing which OEM your PSU was manufactured by), it might not.My question was are cables from the rainforest that claim to be compatible for my Psu alright or shall I look elsewhere?
