A marginal problem

Hi,

1) My PSU is 400 Watts.

2) The latest hardware additions have marginal problems. I.e. SEDNA - PCI 
Express mSATA III (6G) SSD Adapter with 1 SATA III Port. A) The mSATA III 
(6G) SSD is 100% reliable. B) SATA III Port connected to a new SSD is 100% 
unreliable.

Questions:   1) Could the unreliability be connected to something other than 
PSU?
                    2) Would a 500W PSU solve the problem, or
                    3) Would 600W be a better idea?
