Review of power supply. Found to be 99% efficient!

Great looking cable system. Silent with one 120mm fan.

99% efficient is impossible with current technology or so I am told. I find it hard to believe they can pass even the 90% without having a huge PSU that costs $1000+. I am going to read that review but I am VERY skeptical.

Man, 44 amps on two 12v lines is impressive though. I might think about one of these in the future...

"High efficiency of about 80% under wide load range (30-100%) minimizes your electricity bill."

Bah Modular PSU's are overrated I'd rather have the cables coming straight out the back and just do some good cable management than risk having one of those plugs coming undone or just the fact they raise resistance

Tagan U22 480W FTW!!!! but maybe I'm just bias

Yes, you are just bias . I personally like my Antec SP 500watt modular, but thats just me.

it doesnt say 99% efficient. it says 80%. 99% efficiency is impossible with the technology we have nowadays.

Modular cables--- An interview with the founder and CEO of PCPC--
http://www.pcpowercooling.com/about/interview.php
Technically Speaking

An Interview With Doug Dodson, President & Founder Of PC Power & Cooling

CPU: Modular power supplies seem to be gaining a lot of traction in the market, but PCP&C doesn?t make any modular designs. Why?
##this is one excerpt from the whole article##

Dodson: Yeah, it?s real popular, but the industry hasn?t done anything to educate people about modular plugs. The pins that are used in the modular plugs have a very low capacity to pass current. You?re losing power through those pins. It?s electrical resistance between the male and the female part of the pin, to the extent that the voltage drop in just the pins is equivalent to about two feet of wire. The effect is that modular power supplies, everything else being equal, are capable of about 10% less power than power supplies without modular plugs. And that?s under ideal conditions. In real life it gets worse because the pins loosen, corrode, and burn. Over time the resistance builds up. A year down the road, a guy could be running his system and all of a sudden it stops working reliably, and he has no way of knowing that the reason is because the pin inside that modular plug has become corroded or burned. This technique has been out for about six months, but people are going to find that the reliability is a massive failure point. Also, especially given the way people pull their harnesses around and tie them down, it creates a lot of stress on those pins. So instead of the pins having full 100% contact surface to surface, in most cases those pins are only touching maybe 10% or 30% of their surface area. What?s rated for 5A going through those pins, in reality if the pins aren?t making good contact, your rating?s down to maybe 3A, and with that much constriction, those pins just heat up, and it gets worse. For real pros in the industry, no way would they specify that kind of arrangement. This is a consumer-oriented gimmick.

That sounds like total bullshit. Isn't every connection in the computer using pins just like a modular psu? When have those ever corroded or burned, or when have we worried about losing power across them?

Correct me if I am wrong but that "interview" sounds like the marketing "gimmick" here.

You know how many SATA connector's i've broken? cheap pieces of sh!t I swear...I've had a few molexs go bad on me after switching them multiple times...i think the point is if you know anything about electrical resistance, making another thing to plug just adds to the chances of something going wrong, it's not all marketing FUD some of it is true, especially if you swap parts or are doing work inside your case often...it's somewhat true somewhat marketing...

Of course you have one of their units...

Anyway, I think he has valid points but he makes it sound incredibly bad, unless it really is.

Well, the point of a modular psu is not so you can unplug everything when you need to, just so you don't have any wiring that is unecessary. So being worried about breaking connectors on the psu is pretty pointless. Besides, I've never broken any power connector in a pc and I don't think I'm the exception, not sure what your doing to achieve that.

All this aside, my main point is that the added resistance and loss of power across the connectors is negligible and using that as a reason for not purchasing a modular psu is FUD and FUD only.

I suppose I can agree with that for right now, we still dont know how they are long, we can assume since most of the modular PSUs are made by high end manufacturers that they'll last.

And as far as breaking power connectors...those SATA connectors...incredibly easy to break if you bend or bump just a little too hard, i should know from personal experience I broke one today just trying to do some cable management....i was using a zip tie to bunch together my Sata connector, IDE connector and a couple molexs when I hear *crack* and pull the SATA connector from my mobo and the side was cracked thank goodness I had another one...and it's not the first time i've done that...but i think thats just an exception because the SATA connectors are so thin, but i've gone far enough off topic now.

Anyways what would be nice is if someone could do some measuring and see how much extra resistance is being made by having a modular PSU...even if it's minimal

Mr. Dodson also does not seem to have noticed (or conveniently neglected to mention) that certain companies gold-plate their connector crimps to eliminate corrosion and improve electrical connectivity. I see the points he's trying to make, but it's looking a little shaky. Not that they don't have righteous PSUs to offer, and plenty to be proud of, but it smells like broad generalizations at best.

Who gold plates there connection crimps?

Just asking seeing as how I am learing about PSU`s.

At present I have a seasonic.

I am saving for a PC Power and cooling PSU.!

Antec's TruePower family comes to mind. I believe Enermax was doing so even earlier than that, though.

I can't confirm that Antec's NeoHE modular models use gold-plated connectors, so maybe a NeoHE owner will chime in with a reality check At any rate, I wouldn't hesitate to use a modular PSU from a recognized, respectable manufacturer, despite the attempts by Mr. Dodson to inspire fear, uncertainty and doubt over having an extra set of connections involved. I take it he hasn't looked inside a Dell PowerEdge 1600 server, or noticed how SCA-2 SCSI racks deliver power to SCSI drives, or... need I go on?

well I know for a fact the PCPC people do!!
Mine are all gold plated!

Enermax does I believe...
fortron does....
Some Antec models do...
others don`t
Thermaltake Pure power series does
raidmax does...

But I just checked my old OKIA 420 and even the generic OKIA is gold plated or has the appearance of gold plating it could be brass.....

Anyways all good comments!!

Bottom line is that you are satisfied with the PSU that you have!!

All is good!

Just found something interesting. If you don't think this stuff about modular psus isn't all, or mostly, marketing, have a look here: http://www.pcpowercooling.com/technology/myths/

"Look for a new myth each month!"

Now, don't get me wrong, I have owned a PCP&C 510 SLI power supply and I can say it's the best power supply I have ever had the pleasure of running in a pc. But this modular bs is marketing, plain and simple.
