Don't get paranoid with Cap quality or go OTT it's not that critial.
Go with 3 x 4700Uf. They are cheaper and easier to find and provide less ripple than one large Cap. Even the cheap Ebay ones are ok provided you size them correctly. Give them plenty of overhead on voltage and you won't have problem.
I've built probably 100 + and just about every one used 3 x 4700 and never had any issues, Zero failure (Unless I cock up polarity.!!) The PSU running my Own machine is nearly 10yrs old and used Cheap Ebay caps, It's still going strong and as runs for 10hrs day most days.
I buy mine from Farnell.Last edited by JAZZCNC; 24-06-2016 at 11:10 PM.
