It's hard to say exactly without knowing the schema of your table.  I suspect you only want to sum sale by sale that are paid in full and not a sum of all sales that are paid in full.  In order to keep the sum to the sale itself and not an overall sum, you'll need to group by the sale id.

UPDATE sales AS s
JOIN
 (SELECT sale_id,
   SUM(sale_products_subtotal + sale_shipping_charged + sale_tax) as sum_sale_received
    WHERE sale_payment_status = 'Paid in Full' 
    GROUP BY sale_id) AS grp
   ON grp.sale_id = s.sale_id
SET s.sale_received = grp.sum_sale_received

Maybe you should try this:

UPDATE `sales` SET `sale_received` =  
   CONVERT(`sale_products_subtotal`,DECIMAL(18,9)) +
   CONVERT(`sale_shipping_charged`,DECIMAL(18,9))  + 
   CONVERT(`sale_tax`, DECIMAL(18,9)) 
WHERE `sale_payment_status` = 'Paid in Full';
