Antec TruePower Quattro 1200W
by Jarred Walton on July 7, 2010 6:50 PM ESTInterior and Topology
The internal structure of the ATX 2.3 PSU is dominated by two very big heatsinks. This is one reason the 80mm fan can be as silent as other PSUs with 120mm or larger fans. You just need the right topology and an efficient design. However, the heatsink on the secondary circuit is much smaller, as there are many components for filtering and regulation. The main capacitors are from Nippon Chemi-Con as well as on the secondary side with some additional all-solid caps from Sanyo on the VRMs.
Antec is using a well equipped EMI-filter with nice isolated x-capacitors and two PFC-chokes in this interleaved design. We can see two Infineon transistors for switching. They are absolutely famous these days because of their good transmission characteristics. Of course, there are interference-suppression chokes on each rail and a MOV behind the entrance. The safety-distance between the galvanic isolated circuits is more than enough.
Because of the numerous cables and big heatsink there is not much space on the secondary side. We will see if this presents a thermal problem under high load. Most of the wires have shrink tubing. The Silicon Touch IC offers SCP, OVP, UVP and OCP.

If it's a pricey model that you've had for only 6 months why didn't you return it for RMA instead of opening it up? Doesn't Antec have a three year warranty?Don't get me wrong. I too opened up my failed Antec PSU... my ten year old PSU. Replaced it with an Antec 380W Green PSU. Can't beat $30 Fry's special. I also had another Antec PSU fail after 4 years (a TP 430w during their bad years). I still have a TP 550 that is humming along in my wife's machine going on 5+ years. I'd say more often than not that Antec makes quality power supplies. Of course I have switched to using Seasonic PSUs, but they are not cheap.

NeoPower is not exactly a Halo product. It is about a high medium level product.The point is that sometimes you have electronics that are built on a solid design, but fail early. Maybe 1 in 100 NeoPowers would do that.
The NeoPowers had at least average to above average build quality...so I still don't understand your claim that it was cheaply built.

" particularly if you are a gamer with Triple-SLI or Quad-Crossfire systems."The nine fanbois' in the USA that have rigs like that don't read AnandTech. Its likely they don't even read above a 5th grade level, "D00d!"
I wish AnandTech would stop pimping cr*p like this. Only about 1% of the readers need a Kilowatt powersupply. There needs to be more reviews on 400W and lower, highly efficient power supplies that cost less than US$50. These are the PSUs that 99% of the readers need and own.
If Anand wanted to do us all a favor, he would bend the ear of representatives at Seasonic, Enermax, and Corsair, and tell them that is what is needed, not powersupplies that dim the house lights when you boot your computer.

95 Amps on the 12V rail?! Finally. I found a replacement unit for my spot welder. Just kidding, I'm sure this will make a fine plasma cutter power source...Perisphetic - Friday, July 9, 2010 - link
PC tuning enthusiast rejoice. Finally a 2 in 1 solution PSU arrives that can easily weld the sheet metal on the modded case and power the build computer as well. No expense has been spared in making the unit a 80 PLUS uncertified device.HOOfan 1 - Sunday, July 11, 2010 - link
How much exactly do you know about internal PSU design?Maybe you think the generic looked neat and clean because it hard hardly any components in there, while the Antec looked junky because it was crammed full of components.

ok this is so shocking for me, to just see the sight of psu above 1 kilowatt........i mean why do you THINK we SHRINK the chips and simplify the programs(browsers, video drivers) ....this range of products is an OXYMORON for technology and reviewers should not encourage them.molecriket - Wednesday, July 14, 2010 - link
99.9% of readers don't care about this overkill. a complete waste of effort.JimDDuncan - Saturday, December 18, 2010 - link
Almost bought this one till I read a review where they tested with cables that did not have built in capacitors. Basically to get performance from this psu you need those specific cables. Also the capicitors are relatively bulky and could get in the way of a tight multi gpu build. Spent the additional 30 dollars on corsair AX 1200.
