The strider essentials are likely made by a new OEM and thats why they went from dual to single rails. There dont appear to be any significant upgrades from the basic striders at the same wattage but a 34A 12V rail on a 500W unit and a 25A rail on a 400W unit and calling them "class leading" on their site is just a lie.
Doesnt really matter which one you go with they will perform very similarly and are probably rated for identical outputs so go for the cheaper one of them if those are your only options.
amd phenom II x4 945 (3.0 Ghz)
asus m2n68-am se2
nvidia gts250 1GB
2 GB kingston ddr2 pc667
1 sata drive
1 dvd burner
20" LED monitor
Now, I understand the argument "dont gimp on PSU.. if you can spare the $30+ go for it.." etc
BUT, if the ST50F-ES is almost 60% of the price of the corsair, and is probably as reliable (both are 80+), should there be any reason telling me i should still get the corsair?
I would like to hear justification that the extra $30 i would have shelled out for getting the corsair is worth every penny as compared to just getting an ST50F-ES.
