I can get this Super Flower PSU from my friend and I was thinking is it any good? Are those 3.3v and 5v amps high enough? Because I have a 400w PSU with 28amps on the 3.3v and 40amps on the 5v. Those seem too low for me. Is that 5v able to power up my 2,5" external usb hard disk which has no external power source?
