Cables and Connectors

The cable sleeving for the 24-pin connector looks exactly like the sleeving from the EarthWatts Green 380W; the other cables use cheaper sleeving, but it's still better than nothing. The HCG-750 comes with a large selection of fixed cables, so again you'll want to make sure that your case has enough space you don't obstruct the airflow. If you're planning on running heavy benchmarking and/or overclocking without a case, obviously that's not a problem.

Fixed Main 24-pin 55cm
ATX12V/EPS12V 4+4-pin 65cm
PCIe 2x 6/8-pin 50, 65cm / 2x 6/8-pin 50, 65cm
Peripheral 3x SATA 55-85cm / 3x SATA 55-85cm / 3x SATA 55-85cm
3x Molex 55-85cm / 3x Molex, 1x Floppy 55-125cm)

Holy moly! This is what I call a very long CPU cable. In addition the HCG-750 has nine SATA connectors. Four separate PCIe cables would have been nice, but four 8-pin capable connectors on two cables is still more than enough to support dual-GPU SLI or CrossFire systems. If you happen to run a high-end card like the HD 6970 or GTX 580, each GPU requires two connectors so gamers will definitely want at least four PCIe connectors. Note that we wouldn't recommend trying to run quad-SLI or quad-CrossFire using GTX 590 or HD 6990 off a single 750W PSU, considering we can already hit 500-600W with a single GPU at stock clocks.

    I'm not really sure a PSU can ever be a "gamer' dream"...

    Don't you need an apostrophe somewhere in that title BTW?
  • L. - Wednesday, April 13, 2011 - link

    Precisely ...
    Just what is that for a title ?
    This PSU does NOT have a single 12V Rail.
    This PSU is NOT modular
    and it's not even interesting in terms of green-itude.

    Alright it's cheap ... but Gamer's havent quite been known for going cheap so far - there wouldn't be any Fermi today if that was the case.

    I thought the High Current Gamer line is supposed to be a single 12V rail, instead of quad 12V rail as in the TruePower New series. Even though it has 40A per rail instead of 25A, I am better off with Cooler Master GX 750W, which is a single 60A rail. To Antec's credit, at least when it comes to factory rebate, Antec still pay cheques instead of credit cards.

    You are not better off with the Cooler Master GX 750! That PSU has high ripple, poor voltage stability and can't stay to ATX specs when getting close to it's specified max output. You can check several reviews of the CM GX750 from Hardwaresecrets, jonnyguru and HardOCP.

    I wondered the same thing. If you aren't going to stick to the ATX spec for current per rail why not go all the way and just have a single rail and really not need to worry about what is on which rail?

    I have limited understanding of electrical terms, but as I understand it, whether you are on a 120v or 240v circuit you are going to use the same wattage. So, when looking at these efficiency numbers, the benefit is that the PSU is simply wasting less energy in the form of heat. Not, I save on my electric bill.

  • JarredWalton - Tuesday, April 12, 2011 - link

    Efficiency will save on your electric bill a bit. For example, if you're 90% efficient, than a 200W load on the PSU will draw 222W at the wall; with 80% efficiency, you'd draw 250W at the wall -- so saving about 28W in that case. Running 24/7, however, that means you're really only saving about $20 to $30 per year. Turn off a light in your house and you save the same amount of money.

    The other benefit is lower heat inside the PSU, which means the fans don't have to spin as fast to dissipate the heat. It's one reason why modern PSUs are generally much quieter than old PSUs. If you run a game that uses 350W from you GPU + CPU + accessories, an 85% efficient PSU would have to dissipate around 62W of internal heat, a 90% efficient PSU would only need to cope with 39W, and an old 72% efficient hunk of junk would have to cool a whopping 136W.

    As far as input voltages, 230VAC is easier to convert to the internal 12V. I don't recall the exact reasons, but generally speaking 230VAC will give slightly better efficiency at the cost of worse PFC.

    The slight efficiency difference comes from two things.

    1) Which voltage it was optimized for, EU has tighter efficiency requirements.

    2) Parts tend to have inherent resistive qualities or forward drop voltage loss, both of which increase nonlinearly with current. So, if you double voltage you draw roughly half current which makes that loss go down some, and with component forward drop, for example a rectifier bridge could cost 1.4V drop, which is 50% lower drop as a percentage of input voltage on 220VAC compared to 110VAC.

    Higher efficiency has an effect on your electricity bill. How much depends on how long you use the PSU and what the difference is when comparing two PSU's against eachother. You can not decide if you run your PSU off ~110V or ~220V, you are at the mercy of what the wall outlet provides that you connect your PSU to.
    In most countries in Europe we have 220~230V outlets. In Americas I understand it's 110~120V.

    Most of the time you get what you pay for, and I always look for the best bang for the buck.
    Take your time,research,look at the reviews, and also count me in on any rebates.
    Just let your smarts and pocket book guide you!
