Five Highly Efficient Power Supplies: 1200 W and Up

[Tanquen]

Why hide the true price of the Corsair AX1500i? Your showing the price of the 1200i.

They're obviously talking about the global picture. Compared to people running integrated graphics or a single GPU or even laptop GPUs, the number of people running multiple GPUs is not that high.

And of course they've heard of Super Flower. They just think that many people don't know about it.

I couldn't find the Holdup time for Seasonic's PSU in the charts. I really don't think it's a good idea not to include the results for Holdup time, Inrush current, temperature and other metrics in the review

Agreed. This review could have been much better.

Well, you don't seem to understand fully.
They don't really consume more power than the connected hardware demands. On the other hand, they have an amazing efficiency rating, meaning that they use a minimum of power, and are therefore better for the planet. </quote>

Actually, that isn't 100% true. They will still consume more power (idle and load) vs a an equal efficiency rated power power supply where the wattage is matched to the computer's needs. Bigger isn't always better.

i only ever use http://www.jonnyguru.com/ for my psu needs.

I always get a kick out of these companies giving you a nifty little carrying bag for your new power supply. Like you are going to be pulling it out and taking it somewhere regularly.

Where is the EVGA Supernova P2 series? Would have been nice to see it included.

Yeah I was wondering the same thing - I'm highly considering making the move from 80+ Silver to Platinum and I've read nothing but good things about the EVGA P2s. I have the G2 in my Dark Knight rig and it's a great PSU.

Quite so; in fact, quite a few people making similar comments here seem to not understand that the PSU will not "push" more power into the system if that is not demanded by that system. If your configuration requires only 350W max, that's how much will be provided by the PSU.
That being said, the forum is full of PCs crashing upon launching certain programs, launching the OS or even upon booting up, and more often than not this unstable behavior is due to underspec'd PSUs that can not keep up with a sudden increase in wattage demand. Just because a PSU is barely meeting the power rating of your system doesn't mean it will be able to sustain that for any given amount of time.
I, for one, would rather have redundancy built in that can cope not only with current configuration, but also with foreseeable upgrades.

I know it can happen but I’ve never seen it. It’s always something else. If the power supply is suspect then you just unplug everything that you don’t need. If you do that and are still unstable then it’s not the PS. If you unplug everything you don’t need and your are still within a few hundred watts of the PS max then maybe.

I’ve always had way more PS than needed and that never stops all the PCs I’ve have crashing for all kinds of other reasons. Mostly video drivers.

err . . . and the conclusion was ???

The conclusion is that you should go with the Leadex.

For the Antec HCP-1300 Platinum, doesn't 4x +12v 50A add up to 200A and isn't that 2400W? The detail review does say "Combined Output +12V 1300W" but it should also be stated explicitly that all 4 rails can't be run simultaneously at max output. All readers might not realize that.

Though I guess if you link two of the units then there are no issues.

The Enermax is more honest, 4x +12V 30A which does add up to 1440 watts, which reasonably matches the rating of 1500 watts. (In the detail review chart we see how the first rail is 32A so the combined output is actually a little higher -- if that's what it means anyway since the other 3 rails are blank on that row of the chart, which is somewhat ambiguous.)

 

[RedJaron]

There's nothing dishonest about it. Check the sticker on the PSU. Any multi-rail unit will give the max sustainable draw on a single rail and the total draw over the combined rails. It's so people can balance their components across rails if need be. The Antec unit can supply up to 50A on any single rail provided the total 12V draw isn't over 1300W. You could theoretically max out the unit by just loading two of the 12V rails and still be safe.

You may have a point that not all reader will understand draw across multiple rails though.

Where's the best in the PSU industry , the EVGA SuperFlower made models in this wattage range.

I know man! I already said where is the 1200W P2! Kinda disappointing they didn't include them.

 

[Dark Lord of Tech]

I'm disappointed not to see the EVGA SuperFlower models here.

LEADEX PLEASE THANKS.

I still like the interior of my Antec TruePower Quattro 850w. Massive heatsinks!

About that Antec 1300w PSU, according to their site, it says that has a "20+8-pin MBU socket for the needs of tomorrow."
Do you guys have any info on this?

This is the nice thing about efficient PSU's like the V1200, they require less heat sink and generate far less heat than inefficient PSU's. This is how the CM V1200 Platinum can afford to switch the fan into hybrid mode and run at moderate power levels without so much as turning the fan on once.
I bought the Cooler Master Silent Pro Gold 1200w 2.5 years ago and it just started overheating and shutting down recently. This is only half way through my warranty period. Cooler Master was most gracious when I RMA'd it and they sent me a new V1200, which should be arriving in two days. That is some great customer support.

I want to know that what is the perfect solar panel system for decrease the home energy? First of all let me share something about solar energy for those who do not know about<a href="http://www.aurarays.com/commercial-solar.aspx"> Commercial Solar Panel</a>. The high efficiency solar pv modules is made up of all the planets that orbit our sun. In summation to planets, the solar power systems also consists of moons, minor planets, comets, starlet, and dust. This is an vital question, and one that is hitch for scientists to perceive. After all, the manufacturing of our solar power system took place billions of years before there were any people around to hostile witness it.

here is a list of power supplies and who makes them for whom..
