Just got myself a Corsair HX620W PSU with cable management.  Understood and check from the net and confirm this unit is made by SEASONIC.  Got very good review from most stress test website.  And highly recommended by DFI.

Surprising, the Enermax Liberty 620Watts had been strike off the recommended list, as it was claimed to be too many issue.

There is one question I like to ask SHAWTY here, regarding his FSP EPSILON 700W that he sold few months back, was it because it has Crucial ram compatibility issue.

I am having a FSP EPSILON 700W with some issue with my Crucial Ballistix Tracer.  The ram is working fine on DFI Infinity P965-S Dark but not on my Gigabyte P35-DS4 with EPSILON 700W PSU.  But using it with my Crucial Ballistix no problem, as I had two sets of these ram.

Once I clear cmos with jumper.  The system just refuse to boot, when then system is being power up with my FSP Epsilon 700W.  Tried using only single stick of Crucial Ballistix Tracer 6400 on both my Gigabyte P35-DS4 as well as Biostar TP35D2-A7.  Both motherboard with the FSP cannot boot with only beep sound indication ram problem. 

But they both boot up fine with my Crucial Ballistix 6400 with FSP Epsilon 700w   

These Crucial Ballistix Tracer 6400 however works fine without any problem with my DFI Infinity P965-S motherboard using Acbel E2 Power 510Watts. 

Don't know whether the problem is caused by ripple issue from FSP PSU    or what
