FSP Hydro G 650 Power Supply Review

Cross-Load Tests And Infrared Images

Our cross-load tests are described in detail here.

To generate the following charts, we set our loaders to auto mode through our custom-made software before trying more than 1500 possible load combinations with the +12V, 5V and 3.3V rails. The load regulation deviations in each of the charts below were calculated by taking the nominal values of the rails (12V, 5V and 3.3V) as point zero.

Load Regulation Charts

Efficiency Chart

The sweet spot for efficiency is between 160W and 410W, with the load on the minor rails staying below 60W. If you need a wider operating range with greater than 90 percent efficiency, consider a Platinum-rated power supply instead.

Ripple Charts

Infrared Images

Toward the end of the cross-load tests, we took some photos of the PSU with our modified FLIR E4 camera that delivers 320x240 IR resolution (76,800 pixels).

During the full load test in a 47 °C ambient environment, the heat sinks above the +12V FETs get very hot. We measured close to 80 °C on them with the help of our thermal camera. The cooling fan is effective under tough conditions though, and it removes enough heat to protect the PSU's sensitive electronics. The only downside is the fan's noise when it's spinning at more than 2000 RPM.

    I see a Performance Per Dollar chart, but so far I've not been able to find the price of this unit. What is it?

    Hopefully a competitive price scheme. Looks awesome though, very nice aesthetic

    It is 90 bucks

    I remember FSP being an OEM for older computer vendors like DEC, so they definitely aren't a newcomer to the field. I'm glad to see they know how to build a modern supply.

    IMHO FSP has always had a solid but "middle-of-the-pack" reputation; not anybody's first choice, but a lot better than a lot of the junk being sold. Even their Raider units that got very critical reviews were acceptable as budget units in light use. In big box PCs, I'd certainly rather see FSP than HEC or Bestec.

    I see "op amp amplifier" mentioned several times in the review.
    What is an "op amp amplifier"
    Doesn't amp stand for amplifier in this context, which expands to op amplifier amplifier?

    Odd naming scheme for a power supply. Hope it doesn't confuse anyone into thinking water goes well with it. :P

    Always good to see some of the larger if less well known manufacturers putting out quality units.

    op amp is short for operational amplifier.
    op amp amplifier is short for operational amplifier amplifier.
    You need to pay more attention to what is written.

    Good performing power supply. In terms of voltages and ripple, beats the EVGA GS. I would never hesitate to recommend this unit, if it is priced well of course, which it already is not.

    Had this been around $60 or so, it would be on my recommendation list. But at ~$90 I'm not as inclined to recommend it. Yes it is a good unit, but $90 just seems a bit steep for a 650w PSU. I'm more inclined to buy a $60-70 PSU for most of the builds that I do (all at least 80 PLUS Bronze rated). I know that this PSU is probably for those that have extra $ floating around or want more than just 80 PLUS Bronze certified PSU's.

    The GQ series seems hard to overturn, unless fully modular cabling is an absolute must for the consumer. I've never had an issue with semi-modular that made me cringe and exclaim that I should have forked out the extra $10-20. Aesthetics are more of a deciding factor for me, and realistically this edges out the HX series for that blue/white scheme, as far as I'm concerned at least.

    It's nice to have another unit to add to the short list of power supplies worth recommending. I'd like to see a 550 watt unit added to this line.

    It runs for $81 now:

    Which is comparable to the EVGA GS:

    Between the two, I'd take the FSP. I think I'm going to start making this FSP a common recommendation myself.
