Is an 8 that bad of a score? In another PSU review, I gave the Silverstone Strider 560W a 9 out of 10 and it had an active PFC and an extra 60 watts. True the retail version has 2 SATA cables and 2 PCI-E, but that does not make up for the fact that the SATA cable that was included had questionable plastic for the connectors. What is one gave out and your HDD was disconnected.
If you are thinking of using this in your next build, I can say go for it. I was very impressed how stable the rails stood under load and the thing was quiet when running in silent mode. Like I said in the review, "I would have no reservations at all in recommending this to anyone in the market for a new power supply."
I hope this clears things up a bit for you.
