I don't know 4W, I built an AMD64 system and used that Ultra 500w Modular Connection PSU....and weak rails??? Last time I looked at the rails it had 30a for the +12v which is higher than most PSU's you'll ever see.....oops just looked and it says 34a even higher than I thought...30a for the +5 and 28a for the +3.3 seems to be about the right average for most PSU's I've seen, so I don't really think it has weak rails.
I'll agree that it can be scratched easily, but I put it in a Lian-Li case and it fit nice, no scratches and looks beautiful, you almost don't even want to touch the damn thing cause of fingerprints lol...
The little rubber pads they give you to plug up the unused ports are worthless though. They don't stay in at all so I simply took them all out because chances are they would fall off in the case although rubber they wouldn't short anything, I still don't like stuff falling out lol.
And out of the 3 'cons' listed on that review
- Not active PFC
- No PCI-Express or 24-pin power connector included
- Finger prints easily
I'd say the only one that actually matters is the Non-Active PFC (which the thermaltake 560w PurePower PSU has, I have this PSU and it runs great and you guys know how OC'd my system is and how many fans I got
Regarding the few molex connectors, it really does have an efficient amount and for the most part, most fans are pass through connectors so you really wouldn't have to worry about using them all up.
One thing that I think is retarded though is that they don't have SATA Power connectors included and you can send out a 'rebate' type thing to get a set of them I believe...so that's lame.
Other than that I've worked with the PSU, built a machine with it, and personally think it's a worthy buy.
