    Default Re: Are gigabyte power supplies good?

    There are very few web reviews for Gigabyte power supplies.
    Your can check out:
    PSU Review Database - RealHardTechX and Power Supply Review Database | techPowerUp

    The RealHardTechX site includes the name of the OEM manufacturer for each psu model.
    Most OEM's make mediocre to very good power supplies and outfits like Antec, Corsair, bequiet!, Cooler Master, Kingwin, NZXT, OCZ, Rosewill, Seventeam, Silverstone, Thermaltake, and others offer power supplies that are manufactured by several OEM companies. Some of the models are excellent and some are not very good.

    A power supply is the foundation of your system and you should buy a power supply that provides clean and stable electrical power, uses quality components, and is powerful enough to meet your current and future needs.

    Buying a low end, cheap power supply puts your system at risk, might cause instability and will not have adequate protective circuit features to protect the hardware in your system. Do a web search using: gutless wonder power supply review to see what can happen with with an 'el cheapo power supply.

    Which power supply manufacturers make the best mainstream power suppliers?
    1. Seasonic
    2. Super Flower (models from 2011 and newer)
    3. Delta (many models)
    4. CWT (some models)

    Seasonic makes power supplies for XFX (currently all models), Antec (some models), Corsair (some models) and several others.
    Super Flower makes power supplies for EVGA (some recent higher end models), Kingwin (some models), Rosewill (some models) and several others.

    FSP is a typical psu manufacturer that makes some models that are OK and other models that aren't very good. Unfortunately many other major psu manufacturers make similar models that range from borderline acceptable to pretty good.

    I won't buy a power supply unless it gets a favorable recommendation from JonnyGuru, HardOCP, HardwareSecrets, PCPER, TechPowerUp or BenchmarkReviews.

    You didn't provide a detailed hardware list so we don't know if a 720 watt power supply is adequate, or if a less powerful power supply will meet your needs. Check out the Extreme Outervision PSU Calculator (Free "Lite" Online Version) at eXtreme Power Supply Calculator. I've included a screen-shot of my filled in hardware specs and their recommendation for my system.

    See posts #14 and #20 for my psu recommendations in http://forums.tweaktown.com/gigabyte...e-ud3r-v2.html.


    In http://forums.tweaktown.com/asrock/5...estarts-i.html the OP had power supply problems with two different name brand power supplies. The power supply discussion starts in post #17 with his Cooler Master 460watt and FSP/Fortron 600 watt psu problems.

    In post #46, the OP said:

    Yes, yes and yes...

    The Asrock board did not properly power off with either CoolerMaster or FSP supply, but works just fine with the Seasonic G-550...

    Aside from reboots to replace the PSU and testing the sleep/power off feature, the machine has been running over 6 days now...
    A high quality power supply does make a difference.

    There is some good natured humor in posts #48 - #61.

    The following conclusion is from an older HardwareSecrets psu review:

    Gigabyte Superb 550P Power Supply Review
    By Gabriel Torres on April 7, 2010

    Conclusions

    We simply can’t understand why when it comes to power supplies tier 1 motherboard manufacturers prefer to provide low-end products. We’ve seen this happening not only with Gigabyte, but also with MSI </article/666> and ASUS </article/853>.

    Superb 550P is a decent low-end 450 W unit if you pull between 180 W and 270 W from it, when its efficiency touches 80%. On other load patterns, however, efficiency is too low, preventing us from recommending this unit.

    Another thing that counts against this unit is Gigabyte labeling it with its peak power. This, by itself, we think should be illegal everywhere in the world. And to make things worse we couldn’t pull 550 W from it.

    Superb 550P is far from being superb and it is too expensive for what it is. For example, you can buy an OCZ StealthXStream 500 W </article/798>
    for less and get a far better performance.

    edit: The Gigabyte Odin Plus 700 W Power Supply Review | Hardware Secrets was better but they said:

    Gigabyte Odin Plus 700 W Power Supply Review
    By Gabriel Torres on May 27, 2010

    Introduction

    Gigabyte has quietly entered the power supply market, and the other model from this brand we reviewed – Superb 550P </article/Gigabyte-Superb-550P-Power-Supply-Review/968> – proved to be an inferior product. Let’s see if things got better with Odin Plus 700 W.

    Like Superb 550P, Odin Plus 700 W is manufactured by AcBel Polytech <http://www.acbel.com/>.

    .....

    Conclusions

    Gigabyte Odin Plus 700 W is not a bad product: it can deliver far more than its labeled power, presents a very good efficiency if you pull up to 560 W from it and won’t offer any kind of risk of use.

    However, we were a little bit disappointed. Because it uses a high-end design – DC-DC conversion, meaning that the unit is basically a +12 V power supply with the +5 V and +3.3 V outputs being produced by two small switching-mode power supplies attached to the +12 V line – with Japanese capacitors on the primary side and only solid caps on the secondary, we expected more from it. Ripple and noise, although inside specs, were too high in our opinion, proving that the use of high-end capacitors may not necessarily help reducing electrical noise (the use of high-end capacitors has more to do with life-span). The cable configuration was not the best we’ve seen for a product on this power range.

    Everything will depend on the price it will reach the market. For what it offers, we hope it could arrive in the United States costing around USD 100. In Europe this unit is coming with a suggested price tag of €130 (around USD 160), which makes the recommendation of this unit impossible, since we have better units costing way less than that.
