PSU expertise needed . . .

[SR71]

Can I get some input into which of these 2 PSU's would be the best one to get to run this PC build - thanks in advance.
SILVERSTONE SST-ST60F 600W http://www.newegg.com/Product/Product.asp?Item=N82E16817163109
or
PC Power & Cooling 510 SLI-PFC 510W
http://www.newegg.com/Product/Product.asp?Item=N82E16817703001

The build:

SILVERSTONE TJ-03 SLVR
ASUS A8N-SLI Premium
Athlon 64 X2 4800+
Geil ONE 1GB (2x512)
XFX PVT70FUNDE Geforce 7800GTX
2-Seagate Barracuda 7200.8 250GB
Plextor PX-716AL/SW
ASUS 16X DVD-ROM

*Want to be SLI-capable for down the road. I'm a fan of PC P&C PSU's, but I just love this new SILVERSTONE TJ-03 SLVR case and I just came across this PSU by them. Quad+12V rail??? 75.8% efficiency??? Dual+12V??? What's the word here?

Thanks.

I'd have to go with the PC P&C.

Both are awesome power supplies and will barely be stirred to life unless you go with two 7800gtx's. Still, nothing beats a PC Power & Cooling....nothing. Ive used two of the 510's myself and simply put, I will never worry about power in those machines. Its just not an issue to even consider when you have a PCP&C. I mean, they are rated to power 15 hard drives at 50 degrees C......

Thanks for the input - I kind of thought that would be the case. The Silverstone has some different configurations I was unfamiliar with. What's the diff between a PSU with dual+12v vs the PC P&C's single +12vrail? The Silverstone also has an efficiency rating that is 5% better than the PC P&C's (75.8% versus 70%).

Wow, if you're after efficiency, I'd say get sidetracked to the Antec Phantom 500, it's around 85-88% efficiency.

Antec's site doesn't even tell you that, last I looked they were publishing the numbers for the less-efficient European model.

The dual 12v thing is a extremely confusing and thus aggravating issue. I've seen too many conflicting reports to count. Everything from it being a safety issue to it being good for basically nothing.

About the only consistent information I can get out of all it is that it is easier to make psu's more efficient by using more than one 12v rail.
As to whether or not they give you better power characteristics, your on your own. Ive personally decided after wading through all the conflicting crap that whatever benefit/deficit it gives you in terms of power stability probably doesnt matter enough to worry about.

The effeciency rating though is at least something to pay attention to as it can save you money. 5% probably wont get you more than a nice dinner a year though. Its a bigger issue when you have five or more machines all with inefficient psu's.

Still, the ratings on psu's are downright aggravating altogether and I'm praying for the day that some trade commission makes them at least standardize the temperature at which they are rated.

the having 2 12v rails is part of the ATX spec... if the single 12v rail is over something like 16A or 20A (cant remember) it is advised to have 2 12v rails

Trust me I know what I'm doing... ooops, grab the cat...
