1000W-1200W Roundup: Five High-End PSUs
by Martin Kaffei on December 9, 2010 1:20 PM ESTAntec HCP-1200 (High Current Pro 1200W) Overview
Our HCP (High Current Pro) sample arrived without any packaging, as it was one of the first samples and the final package contents weren't yet finalized. The shipping product includes the standard mounting screws and manual, plus the modular cables. Unlike the other PSUs in this roundup, Antec is using an 80mm fan from Sanyo Denki for cooling, reminiscent of old PC Power and Cooling designs. The case is 18cm long, typical for high wattage PSUs.
| Cables and Connectors | ||
| Fixed/Modular | Main | 24-pin 65cm |
| ATX12V/EPS12V | 4+4-pin 65cm / 8-pin 65cm | |
| PCIe | 4x 6/8-pin 55cm + 4x 6/8-pin 15cm | |
| Peripheral | 3x SATA 55-85cm / 3x SATA 55-85cm / 3x SATA 55-85cm / 3x SATA 55-85cm | |
| 3x Molex 55-85cm/ 3x Molex 55-85cm / 3x Molex 55-85cm + Floppy 15cm | ||
Antec offers many SATA connectors but you can't conect all of them if you want to use all the Molex cables as well. The reason is there aren't enough sockets on the modular cabling system, so you're limited to choosing which cables you will use. Like Cooler Master Antec has eight PCIe connectors but they're longer and all have 6/8-pin heads. The two 8-pin connectors for CPUs are relatively common for 1200W PSUs, again just like the Cooler Master.
The 80mm fan is a ball bearing type with the product number 9AH0812P4G131 with a lifespan of 120,000hrs @ 40°C and up to 4500RPM. That sounds high, but as we will see later Antec manages to turn in some impressive results.
Antec has two PCBs with four (!) main caps from Rubycon. On the secondary side we can find more Rubycon caps and some all solid Nippon Chemi-Con caps as well. The transformer looks very small like the one from Cooler Master and there are very modern transistors with a low drain-source resistance. The protecion IC can be found on the second picture on the right sister PCB. The soldering quality is absolutely flawless.

Ditto! I have bought nothing but Corsair powersupplies for quite some time. I got tired of my Antec supplies dieing out on me so I switched to some of the others (Seasonic) but once I found the new (at the time) Corsair's lineup... There was no competition. And generally speaking, I don't buy their ram or other products, but their power supplies are rock solid.Squuiid - Thursday, December 9, 2010 - link

Well, we can't test all brands out there, but we've already reviewed the AX 750, which is a very good PSU and this roundup wasn't the last one. I'm sure, Corsair will send more samples, if you are interested.landerf - Friday, December 10, 2010 - link
The AX 750 and the AX1200 are hardly comparable. You can't just assume by the model line, especially with corsair. They're not made by the same manufacturer. The AX is considered "god" tier at the moment, so it'd be expected to be in any such comparison.landerf - Friday, December 10, 2010 - link

Still the AX1200 belongs among the tested products as its the only one that is in the same range as the Antec High Current Pro 1200WJerricho24 - Friday, December 10, 2010 - link
I also have a few corairs and would have liked to see the AX1200 set along side the enermax Revolution 1250 or Galaxy 1000(that I also have both of)the REAL top end players seem to be missing from 1000W+ review.

...it's good to expose that some known and unknown brands have mediocre PSU quality. Now days you need to consider accurate PSU reviews on the specific model PSU you are considering purchasing as the quality and performance can vary drastically from one PSU model to another of the same brand.SirGCal - Thursday, December 9, 2010 - link
Even the Corsair CMPSU-1000HX or CMPSU-950TX would have been interesting in the mix. Let alone the AX1200 monster.But still, the majority of users who aren't running tripple SLI won't need anything more than a 600-900W unit depending. It would be more interesting to see a good comparison of say the ~750W range. That'll hold most systems even with two GPUs in many cases. But no problem at all with any single GPU as the majority of users run.
