Yes these are non brand name capacitors but if they are the main filtering capacitors they might be alright but if they look swollen in any way do not trust them to be good anymore any capacitor that it’s voltage is less than 100 volts I would highly recommend that you replace them with name brand capacitors if they have a UF value of 100 or less replacing these are very important to be replaced
