Antec HCG-750 review COMMENTS

post #1 of 16
Thread Starter 
I'm doing a dissection review of the Antec HCG-750. The review is going up on HardwareAware, but in the meantime while doing the review and writing it I'll post my thoughts here.

First thought upon unboxing: HA HA. They copied Corsair's trick of putting the PSU in a bag! It's not a velvet bag though, more of a canvas-y plastic-y sort of bag. Not quite as luxurious as Corsair's velvet, but still pretty neat. Weird bit, though, is that since this is a non-modular PSU what purpose does the bag serve? thinking.gif I guess some scratch protection? Eh, Corsair did it with their non-modular PSUs as well.

Just thought that was funny.



Oh, and stop with the "Designed in California" thing, it was designed in Taiwan in cooperation with Delta Electronics. I know for a fact your California office only has a handful of engineers and none of them are full-time involved with the PSU designing process. 99% of the design work is done in Taiwan, so saying it was done in California is dishonest.

I've got some new macro filters and they're great, helps get around the mediocre min-focus distance of this lens.

The manual calls this the "HCG-750/750 RED/900". Perhaps there were going to be multiple colors? Or maybe one with a red LED fan? One thing I can tell you is this PSU would fit in perfectly with the red version of the LANboy Air.

Took some pictures of the review in progress, just in case anyone was interested.

Yes I do reviews from my dining room. DON'T JUDGE ME.

Some of the equipment used; my laptop, some precision screwdrivers, filters for my camera, scotch tape and a flashlight (both come in handy occasionally). Now all I need is a Chroma and an oscilloscope and we're gold!

Photography needs a lot of lighting.

I wonder, who in the world was ungodly stupid enough to put one of these gel packs in their mouth? What imbecile committed this unspeakably retarded act that causes hundreds of thousands to be spent on printing "do not eat" on these little gel packets that are shipped in electrical equipment all over the world?

Oh, that explains it.

Much easier to get open than the TP-750. No threadlocker on the exterior screws.

The interior design is very clean, almost sparse. At least until you get to the secondary, which is of course very crowded due to a daughterboard, filter caps, and the output wires.

The shunt resistors for the +12V OCP are *very* noticeable, massive resistors.


Anyway, design is standard stuff, double forward topology, indy-regulated secondary, nicely populated transient filter, nothing too unusual or unconventional. Still, this design is *clean*, and very aesthetically pleasing with all heatsinks finished in black and a black solder mask. Of course, that doesn't count for anything when it comes to performance.

This PSU has no MOV that I can see. I'm rather disappointed, you can't rely on the user to supply surge protection. Yes I can see the arguments for cutting it, but it's a $0.05 component, add it back in. There's room, in this model at least.

Primary caps are Rubycon, having trouble IDing the secondary caps.

Edit: secondary caps are NCC. One or two other caps around that I haven't identified yet.

I remember that from Hardwaresecrets' review. Quite sad for a solid PSU like this one.

After looking closely at the HCG-750 I couldn't help thinking there was something familiar about it. Then I happened to look at some pictures of the old Earthwatts EA650 and thought, 'Ha!'

The HCG-750 and EA650 have very similar internal designs. Note, they are not in any way the same power supply, there are very significant differences, especially in the PWM stage, and the HCG is far better stocked with higher quality and higher capacity capacitors, and higher rated silicon components. But the PSUs' transient filter layout, primary side design, and secondary are all very similar. It wouldn't surprise me if Delta and Antec engineers started with the EA650 platform when they designed the HCG-750.

Note that it is *not* similar to the EA750, which uses an entirely different platform.

Hey, those gel packs are delicious.

Woah, how could I missed this thread! Thanks for the review Phaedrus.

This isn't the review, I'm still writing that. This is just some of my comments and ramblings that wouldn't make it into the final cut.
