*12V@16/28A* what exactly does this part mean? can it support up to 28 amps on the 12v line?

Anyone know?

Welcome to the forums!

I've always taken those Aopen double numbers to mean this PSU has two sets of specs - one where the PSU is loaded down on the 3.3v and 5v rails, and a second one where the 12v rail is loaded down instead. Thus, it's rated 16a @ 12v with the other rails loaded, or 28a with the other rails at about half load. Not sure about this though - haven't seen any load testing on this one to know for sure.

What I do know is that this PSU is a real brute, and underrated as most Fortrons are. Haven't seen a system yet on these forums that has maxed it out. I'm getting one next week myself

Dual 12's stay far away. Get a enermax with a nice beefy single 12 if you OC.

The Fortron doesn't have a dual 12V rail. And IMO its one of the best psu's out there, second only to PCP&C.

No thanks - haven't seen enough improvement in build quality to buy one over Fortron. One must keep in mind those high Enermax 12v ratings can only be attained at 25 degree Celcius operating temperatures and when the other rails aren't stressed. The newer Noisetaker/Coolergiant lines are definitely improved compared to past models, but not so much I want to run out and buy one. Not that Enermax isn't decent, far from it, I just don't care for them when Fortron is cheaper, better engineered, and more reliable.

IIRC, these newer Enermax units do indeed have dual 12v rails.

Sure dude. Fortons crappy 12V rail which both cpu video card run off these days is what fried my last system. (granted I was using the 400W model)

Anyway OP, Just read how enermax dominates ALL with the highest effecintcy on the PSU planet. there are more reviews out there too showing enermax voltage stabity and superority just look for them..

Go with the Fortron, adjustable pots and steady rails a bargain on a great power supply

It's funny how people either love or hate Enermax with a passion.

But, I guess BeerHunter's right. The Fortron must have a pretty crappy 12v rail if all it can handle is a 4.2GHz P4.

SPCR, you're kidding right.

And also, I used to run a quicker system than yours off of a 300W Fortron. Dunno how you could've blown a 400W Fortron with it.

Been there, done that, still not that impressed. Those Noisetakers are definitely improved in design over past Enermax units, but my professional opinion as an electronics tech with almost 16 years experience is that I can do better for my money. And I do not make this decision lightly - I have used several brands in the past including Enermax.

You obviously love your Enermax - I have no problem with that... I have several friends still running the older 431w models without any problems who love theirs too. However, I don't think I'll be changing my mind on the Fortron 530w or which PSUs I recommend to others in the market for one.

My 350W Fortron has rock solid voltages (tested with a good DMM), and I'm using 2.1 vcore with my M2600 @2800 MHz.
The Fortron 530W is the the second most highly recommended psu at Xtremesystems forums (#1 being PCP&C, of course).
