Antec High Current Pro Platinum 850W Power Supply Review

Manufacturer: Antec

Under the Hood

View Full Size

Here are a few pictures showing the layout and components inside the High Current Pro 850W Platinum power supply.  The High Current Pro Platinum series features a server-class full-bridge LLC topology with synchronous rectification and uses DC-to-DC converter technology.  The LLC resonant design allows for zero voltage switching, which dramatically lowers switching transistor losses to boost efficiency.  Once again, Antec has teamed up with Delta Electronics as their OEM to co-develop the High Current Pro Platinum power supplies.

Once inside, it becomes quickly apparent that this really is a “new platform”.  The most obvious change is what Antec refers to as a “wireless PCB design”.  The normal maze of output wiring is absent and most of the electrical connections are made through the PCBs instead of external interconnects.  Even the main transformer uses sheet copper instead of the more traditional wire windings. Direct copper wire connections to the synchronous rectifiers also help reduce losses and achieve 80Plus Platinum efficiencies.

The two primary capacitors are made by Nippon Chemi-Con and are rated for 390uF, 450V, and 105°C.  The secondary features both electrolytic and solid polymer caps also made by Nippon Chemi-Con; very nice.  Notice that both the +3.3V and +5V DC-to-DC converter boards have been moved off the main PCB and instead are mounted directly to the front modular DC connector board, eliminating more wiring and reducing current losses and boosting efficiency.  This is functionally what Seasonic did with their X-Connect series of PSUs.

The overall layout, build quality and component selection appears to be excellent.

Modular causes more resistance...I look for a PSU with as few interconnects as possible.

Which does not make appreciable difference and top of the line modular PSUs can achieve as little as 0,5% deviation on main rails between idle and full load.

Also non-modular is too impractical above certain power level, with too many cables to hide.

Why doesn`t the US switch over to 240V ?
It is more efficient.

I'm guesing costs of adapting infrastructure will be pretty enormous.

It is (was?) the biggest market for consumer electronics and appliances designed for 120 V since 1945. About half the current homes were built before 1970 and were not designed for the higher voltages (look up knob and tube wiring on wikipedia). Those all have to be upgraded along with the electrical grid and connections to the homes. Then you need some sort of 99.9% foolproof way for the current wave of people starting to suffer from Old-heimers to plug in all of the devices they have owned for 60 years.

I have 240 in the garage...I guess I meant to say on newer houses they could have a 240 option in the bedroom/living room...we could run more high-powered video cards easier !
240v standard in man-caves.
Is 240v a lot more dangerous ? I know the amps you can pull is at least double.
Why did Europe get to go 240 and not us ? Excepting most US garages. Welding/washers/dryers.

I got my answer...answer.com LOL
The US system theoretically could be made as good or better than the European system with no infrastructure change, except appliances and consumer structures themselves (collectively costing home owners billions). US houses get 240 volts at the panel. If wall outlets all were fed with 240V you'd have the lower current and higher power advantage of the European system and it would be safer too, since each "hot" would still be only 120V from ground (not 240V) which keeps the reduced shock hazard advantage. Of course it is still possible to touch the two hots.
(So in a way our system allows for more flexibility)

Weve got 240v over here its fucking sweet if america was to switch to 240v from 120v i think the costs would be extreme plus all your electrical appliances would need to be replaced or you could use a coverter best of just getting solar or a beefy generator that supplies 240v 15amps
