The Antec HCP 1200 is currently the best top notch psu.

There's a lot of inaccuracies in this article. So many that it makes my brain hurt.

It includes Enermax as a premier brand, when they offer the NAXN 350 & 450w units which are based on the increasingly old CWT PUFP platform.
On the other hand, they put CWT in the low end of manufacturers when they really only manufacture one bad design at the moment (PUFP.)

To top that off, their list of PSU's and the OEM is increasingly out of date. Even on the biggest company (Antec) and some of the easiest to identify products from companies like Thermaltake (they almost always include internal shots of their PSU's.)

For that matter, Silverstone hasn't done a unique design in ages; Corsair just has one (the AX1200), and PC Power & Cooling, along with Tagan, never did unique designs.
PC Power just chose the rear 80mm exhaust version of Seasonic (and early FSP) designs. Now just using the basic Sirfa/Highpower designs.
Tagan just used Topower designs and now they use a few different OEMs.

Corsair AX1200 anyone? Slightly offtopic, but I figured I might as well bring it up

Well yeah, but that's what those PSUs are still made for. They're all cheap, junk units because noone trying to keep a Pentium-II alive is going to pay $50 for a PSU. But those ratings don't necessarily mean something's "wrong", it just means that if you bought one for your new i7 you'd be using it in the wrong way and if it blows up it's pretty much your fault .

If you need to replace a ATX12v 1.x PSU, it is most likely low power OEM or a old server.

Even on older machines, there should be enough load on the +12v (CPU/motherboard) so crossloading should not be a big issue.
Actually, on the original ATX spec the only things that used the 12V line were motors: fans, HDDs, floppies, CDROMs (and only their motors, not their electronics). Everything else: CPUs, motherboards, GPUs, and AGP/PCI/ISA cards all drew from 5V/3.3V. So really you're talking about 12V loads around 5-10W for most systems, with a combined 5V/3.3V load anywhere from 50W to 150W depending on the system.

CPUs and GPUs didn't use the 12V line until the Pentium 4 and GeForce 6800 generation.
