High Power HP1-O21000GD-F14C PSU Review

High Power is a PSU manufacturer, meaning that it mostly provides platforms to other brands instead of diving deep into the retail market. The newest product in its portfolio is the HP1-O21000GD-F14C which achieves high performance and is also equipped with a 12VHPWR connector, able to provide up to 450W. 

I’ve known High Power for quite a long, and I am highly familiar with its products. This manufacturer was among the first to release an ATX12VO PSU and was among the first to release a PSU compatible with the tough ATX v3.0 spec, featuring a 12VHPWR connector, meaning that it passes all corresponding transient response tests.

The HP1-O21000GD-F14C uses a fully modular cable design. Unfortunately, I don’t have any pricing or warranty info for you since this depends on the configuration. One brand can order this platform with full Japanese caps and long cables, while another can take it with lower-grade caps and shorter cables; hence its price will be lower, and the warranty period won’t be as long as in the first case.

Box & Bundle

The samples I had didn’t have any retail package, so there is nothing to show you here. Most OEM samples are like this, no package and relevant design since the client is responsible for the package design and chooses what will be included in the bundle.

Product Photos

The exterior design is plain since this is an OEM product. The brands usually change the casing according to their budget and taste.

Cables

The cables are long, and the provided number of connectors is adequate. Moreover, you will find a 450W 12VHPWR connector.

OCP is set high at 12V, and the same goes for OPP. The minor rails are strong on paper, so the actual OCP triggering point falls within 130%. Still, there is no point for 30A at 3.3V since modern systems only lightly use this rail. That said, I didn’t notice any load regulation or ripple suppression issues.

Over temperature, protection is set higher than usual because the PSU has a semi-passive mode.

High Power used top-of-the-shelf parts for this platform, including Rubycon caps for the primary side and a high-end mix of Rubycon and Chemi-Con electrolytic caps on the secondary side. Moreover, it used a large number of polymer caps by FPCAP. The cooling fan is also of high quality; the same applies to the FETs on both primary and secondary sides. The platform’s design is typical in the mid to high-end categories: half-bridge topology and LLC resonant converter on the primary and synchronous rectification and DC-DC converters for the secondary side.

Testing Methodology

I follow Cybenetics’ PSU testing methodology since I use the same labs. Moreover, the same methodology describes the performance algorithm that I use to extract overall performance. This algorithm has been updated several times, so in some cases, where I have to include some older products, I have to use older versions. This is why in some reviews, you might notice deviations in overall performance compared to other reviews. Finally, if you are wondering about my equipment, you can look at the following scheme.

Load Regulation

Load regulation is satisfactory.

Ripple Suppression

Ripple is low on all rails. It could be even lower at 5VSB, but I am not so demanding on this rail.

Transient Response

I would like to see a tighter transient response on all rails, especially from an ATX 3.0 PSU.

Transient Response – ATX 3.0

The PSU passes all power excursion tests with the extra capacitance that the ATX 3.0 requires.

Hold Up Time

The hold-up time is long, and the power ok signal is accurate

Timings

The PSU supports Alternative Low Power Modes.

Inrush Current

Inrush current is low at 115V and on the high side with 230V.

Efficiency Normal, Light & Super-Light Loads

The platform is efficient. There is room for improvement at light loads, though.

Average Efficiency 5VSB

High Power should use a more efficient 5VSB rail.

Vampire Power

Vampire power is low with 115V and could be lower with 230V.

Average Efficiency

The average efficiency is high, especially if High Power lists this PSU as Gold (in the 80 PLUS scheme).

Average PF

The APFC converter performs well.

Average Noise

Average noise output should be lower, given the efficient platform.

Fan Noise & Speed Maps @ 28-32 °C

With up to 330W load, the PSU’s fan doesn’t spin. It takes more than 590W to exceed 30 dBA, and with 800W and higher, it enters the 35-30 dBA zone.

Overall Performance

This High Power unit performs extremely well, meeting eye-to-eye with formidable opponents from Super Flower and Corsair. FSP’s G7 platform and the Super Flower Leadex V Pro Platinum remain on top. With 230V input High Power’s offering achieves a good place in the overall performance chart.

Epilogue

I haven’t tested a high-performance unit from other OEMs than the usual ones, CWT, Seasonic, and Super Flower, for quite some time now, so it was a pleasant surprise to see a new and competent platform by High Power. The HP1-O21000GD-F14C sample that I had used top parts but these alone cannot guarantee high performance. It is like a recipe, you might have the proper ingredients but mess up during cooking, so the final results are not up to the expectations of the parts used. Thankfully, this is not the case here. On the contrary, this High Power unit met eye-to-eye with some of the best units in this category and now comes down to the asking price. If this is on par with the competing OEMs, we might see this platform soon used by key brands in the business, and it is always nice for all of us consumers to have more choices.
