Antec TruePower Quattro 1200W

| +3.3V regulation | |
| Load | Voltage |
| 10% | 3.33V (+0.91%) |
| 20% | 3.30V (+0%) |
| 50% | 3.27V (-0.91%) |
| 80% | 3.25V (-1.51%) |
| 100% | 3.21V (-2.73%) |
| 110% | 3.18V (-3.64%) |
+3.3V is often the weakest rail with ATX-spec loads. A modern system doesn’t need many amps from this rail, but a power supply shouldn’t have problems reaching the advertised performance. In that sense, –3.64% is not the best result, but still it's still not a problem. This rail is very stable from 10-50%, after which the drop becomes larger. The load was 1.58A at 10% and 17.36A at 110%, but modern systems aren't likely to exceed ~50% load on this rail.
| +5V regulation | |
| Load | Voltage |
| 10% | 5.00V (+0%) |
| 20% | 4.99V (-0.2%) |
| 50% | 4.97V (-0.6%) |
| 80% | 4.94V (-1.2%) |
| 100% | 4.92V (-1.6%) |
| 110% | 4.90V (-2%) |
+5V starts at an optimal level with 5.00V. Usually we like this result to start higher, because there is often a large voltage drop under higher loads. There's not much room for a drop, but as you can see, it is still very stable. Even at 10% overload (-2%) all measurements are within the ATX specifications. The load was 1.89A on 10% and 20.83A on 110%.
| +12V regulation | ||
| Load | Voltage (best) | Voltage (weakest) |
| 10% | 12.17V (+1.42%) | 12.13V (+1.08%) |
| 20% | 12.21V (+1.75%) | 12.15V (+1.25%) |
| 50% | 12.18V (+1.5%) | 12.12V (+1%) |
| 80% | 12.12V (+1%) | 12.07V (+0.58%) |
| 100% | 12.07V (+0.58%) | 12.03V (+0.25%) |
| 110% | 12.04V (+0.33%) | 12.00V (+0%) |
+12V shows an untypical regulation and increases at 20% load with up to 12.21V. However, the voltage is always over 12.00V. +12V5 was always the weakest rail here but still better than most of the results we have measured in previous tests. The load was 8.65A on 10% and 94.95A on 110% (for all rails combined). By the way +12V has an OCP of 50A at all +12V rails, which is quite high.
With the OC version you can adjust the rail up to 12.6V, for those setups where one cable has to transfer very high currents with their accompanying high voltage drops. Most users will have no need of this feature, as the internal regulation is very good.
| +5VSB regulation | |
| Load | Voltage |
| 10% | 5.10V (+2%) |
| 20% | 5.09V (+1.8%) |
| 50% | 5.05V (+1%) |
| 80% | 5.01V (+0.2%) |
| 100% | 4.97V (-0.6%) |
| 110% | 4.95V (-1%) |
The well dimensioned +5V Standby rail starts higher than the other +5V rail. The load was 0.29A on 10% and 3.17A on 110%.

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.
