i5-2500k @4.4Ghz 1.320
MSI Z68-G45
x2 7200RPM HDDs
Samsung 840 series SSD
SLI GTX 560ti 448 Classy Ultra

Was looking at HX850 or 750 or EVGA 750W?

Will there be a difference if the PCI connector is split into two connectors instead of one? Like on the XFX Pro Series above. Got a Seasonic 620W right now and it has had no problems for 2 years .

Hi - If you have the(molex) pcie adapters, your Seasonic 620 has enough
+12v amps to run that system. Depending on which 620 you have,
non-mod has 49-+12v amps, & the modualr 620 has 48-+12v amps.

You might want to upgrade anyway, but it's not required. Personally, I
would upgrade as using 2 - molex to pcie adapters doesn't appeal
to me. A quality 650 or 750 are more than enough (just make sure if it's
a 650, it has 4 pcie connectors, some 650's do & some don't)

All quality 750's will have at least 4 pcie connectors.

Since you have a 620, 650 isn't really an upgrade, so go to 750 if you
upgrade. I believe some good ones are linked above.

The XFX 750 blackbird linked is an excellent value, and it's Seasonic built.
