FSP Hyper K 700W Introduction

Back in June, FSP products were made available in Pakistan’s Market thanks to Shingpoint distributions. And in the previous month, we had the opportunity to meet with the person in charge for Pakistan’s market from both FSP and Shingpoint in a bloggers meet event. At the event, we discussed the company’s history, what they do and are planning to do in the PK’s market. We also discussed two of their PSUs in depth, namely the FSP Hydro G 650w and FSP Hyper K 700W. And after the event, we were handed out the FSP Hyper K 700w for our in-depth analysis and review.

All that may look random to you in case you don’t know who FSP is and what exactly they do. But in case you do follow the international PC market, then I’m pretty sure you must have heard of their name. Founded in 1993, FSP is a well-known brand in the international PSU (Power Supply Unit) market. They also hold the record for the most 80+ rated PSUs, 437 in the 115V category alone. Which means there are a lot of options for you to look at. Nobody comes even close to that number. There are a few famous names in the PSU market you might be familiar with, but you wouldn’t know that they actually buy the designs from other companies. FSP on the other hand manufacture their own PSUs. And they don’t only manufacture/design the PSUs, rather they even manufacture some of the parts used in their PSUs at their own factories which enables them to have more control over their overall design.

Coming back to the PSU that we are looking at today, the Hyper K 700W. As the name suggests, It’s a 700 watt PSU but with the 230v 80+ rating. Now you must have heard of the 80+ rating, but the 230v EU rating must be something new for you. Well, in short, it means that the PSU is 85% efficient at 50% load while 82% in most of the other load cases.

Other features of the PSU include active PFC, single +12v rail, SATA array cable, over current, over voltage and short circuit protection, and meets ErP/ EuP 2013 standards. And no, it’s not semi-modular or fully modular PSUs as it’s meant to be a budget-friendly yet efficient PSU.

Here’s what FSP has to say about their Hyper K series:

So let’s dive deeper into the review and start with the unboxing.

FSP Hyper K 700W Unboxing

So we get the FSP HyperK 700W in a yellow/black themed rectangular box. On the front, we have a picture of the 120mm fan with the grill on it that’s being used in the PSU. We also have the FSP logo at top left corner and the model name at the bottom right corner. Some features like 80+ 230V EU, 5 years warranty*, Intel Latest CPU ready and VR Ready are also mentioned.

At the back is where you’ll find the interesting bits about the PSU. In the left section, we have a power distribution table, features, and power cord type. While on the right side, we have the types/numbers of cables mentioned with a visual representation of it.

At the bottom, a statement to visit FSP’s website for more information in multiple languages is present.

And at the top, a QR core for the FSP Power App, their contact information and the model number is listed.

Once you open the box, you’ll be greeted with the warranty card, a multilingual product manual and a paper in a foreign language that I do not understand.

The PSU and the cables are properly protected in the box. The PSU gets it’s own foaming body while the cables were covered with cardboard.

And this is the FSP Hyper K 700W PSU. It comes with a power cord and 4x screws for mounting it on the chassis. Now let’s have a closer look at the PSU itself on the next page.

FSP Hyper K 700W Closer Look:

So this is what the back of the PSU looks like. We have a hive-like grill here. That’s to let the hot air pass out from the system. Then we have a switch for PSU power and the socket for the power cord.

The sides of the PSU are empty, no branding or design here. However, one side has a warranty sticker applied over a screw, so say bye bye to your warranty if you want to disassemble the PSU for whatever reasons.

On the front, we have all the cables coming out from one side and we also have some cuts on the body. These cuts help with the overall airflow inside the chassis.

At the bottom, we have the 120mm fan. There’s not much detail mentioned about the fan itself other than the noise reading on FSP’s website. Also, the fan is behind a grill preventing any accidental injuries and as well as keeping the footprint on airflow minimum.

And at the top, you’ll find the information sticker with the input/out voltage details table and some warnings and certification along with the P/N and S/N numbers.

Now let’s have a look at all the cables coming out of the PSU. So starting up with the SATA cables, we have 2x SATA Cables. Each cable has 4x SATA headers however if you look at them, both cables look different. Well one of them is the normal SATA cable that you see mostly in the market with about 6-inch distance between each header with a total length of 38 inches. While the other cable, which FSP like to call the SATA Array cable has the headers only about 2.5 inches apart from each other with a total length of 28 inches. This type of cable is perfect for chassis that have HDDs stacked over each other.

It does come with 2x PCIe Cables. Each cable has 2x 6+2 pin headers. Lengthwise, it’s about 20+6 inches.

On the Molex end, we have 2 Molex headers and 1 floppy drive header with a total length of 20+6+6 inches. Well, I’m not sure why we still have PSUs with Floppy drive header but I’m glad that we only have 1x Molex cable with only 2x Molex headers on it. To be honest, I find Molex cables a burden on PSUs and a waste of room, but PSU manufacturers still need to include them with their PSUs to meet the standards. And you might not use a Molex HDD nowadays, but there are still other devices like LEDs, adaptors etc that still comes with a Molex connector. And having required only one Molex header on such devices, you end up using the whole Molex cable with 2 or more Molex headers as an extra.

The EPS 2x 4pin cable is about 24 inches in length.

And here’s the standard 20+4pin ATX cable which is about 22 inches in length.

And umm, yea, we did void the warranty just so you can see what the interior of the PSU looks like. Well, why not! The Shroud is held in place by 4 small screws, 2 on each sides. However I also had to remove the fan screws just so I could get the top cover removed properly.

Unlike certain other PSUs, the fan on this PSU is soldered to the PCB. So in case if the fan dies and you’re out of warranty, you cannot just swap it with a new fan. Rather, you’ll have to de-solder and solder a new fan to the PCB. Also, the fan on this PSU doesn’t have the feature where it stops spinning on low load.

And here are some more pictures of the interior of the PSU. I’m not much knowledgeable on these electrical components, but one thing that even a novice can notice is the neatness of the interior. I’ve seen a few PSUs that are plastered with glues and what not, but that’s not the case with this one. Most of the capacitors used on this PSU are from CapXon while the larger 420v one is from TEAPO. These capacitors aren’t considered as the best one available on the market but still does it’s job and saves a few penny for the company. Also, there’s no insulation under the PCB.

Reviewing a PSU properly requires special equipment which can cost a few hundred dollars. In our review, we will only be looking at the voltage stability of the PSU which can easily be done by a multi-meter. The multi-meter we used in our test was UNI-T UT202. But just for the peace of mind, we also measured the readings using the HWinfo64 software. However, the readings in the software aren’t too credible compared to our multi-meter test.

Minimum, maximum and average ratings were noted from both the meter and software. Both idle and load condition readings were noted. To put load on the system, we ran the Aida64 Extreme Stability test on all components. Readings were taken a few minutes into the stress test. These readings are for +3.3v, +5v and +12v lines. Our multi-meter has an error margin of 0.1% by 10mOhm.

Note that neither the GPU nor CPU was overclocked in our testing. At idle condition, the system didn’t take more than 30w from CPU and GPU combined which is about 5% of the total value the PSU can handle. PSUs tend to be less efficient under 10% load unless it is 80+ Titanium rated. But when we stress tested the system with Aida64 Extreme, the system was taking 135W+ from the CPU and GPU combined. And that’s about 20% load of what the PSU can handle. This is where the 230v EU white rated PSU becomes 82% efficient. Which means if my system requires 135W, then the PSU is pulling almost 165W from the wall.


So as we can see, in the idle condition, the PSU voltage readings are a bit off the mark. But don’t make an immediate uninformed assumption as everything is still within the safe range of 5% difference from their rated values. Any PSU above 5% difference from the rated voltage on either line should be an immediate no go. According to our multi-meter, our +12v line is off by only 1.4% from its mark. While the +5v line performance is within 2% and our +3.3v line within 0.3%. Everything looks good for under 5% load of the PSU’s rated wattage. The minimum to maximum reading difference is also not too big which is a good sign of voltage stability.

And when we put some load on the system, things start looking even better, especially on the +3.3v line. Our +12v line has dropped within a range of 0.82% difference. While the +3.3v line shows a stable performance within 0-0.3% range. However, the +5v line performance doesn’t seem to have changed much.


The FSP Hyper K is a budget-friendly series from FSP ranging from 500W to 700W and is also 230v EU 80+ Rated. Which means you’re getting about 82-85% efficiency from this PSU on typical load. The one we tested today was the 700W which is priced at around 6600 PKR at Shingpoint.com. With this PSU, you can easily run a system with i7 8700K and a GTX 1080 or 2x mid-tier GPUs along with other storage and RGB stuff. But if you’re running a system like ours as mentioned in the test rig, you’d be better off with the Hyper K 500W PSU that will only set you back 4700 PKR.

The only downside I found with this PSU was purely aesthetic. I mean it doesn’t have sleeved cables other than the 24 pin ATX cable. So you will be witnessing the yellow/red individual cables which somewhat gets hidden with the sleeves. And neither is this a semi-modular PSU. But if you are looking for a semi-modular PSU in this price range, you’ll have to decrease the maximum PSU wattage. The only competitor that we see for this PSU in our market is currently the Thermaltake Smart RGB 700 PSU that we also reviewed a while ago, which features sleeved cables and an RGB fan. Both of which are missing on the FSP Hyper K at the same price. So the price point could have been a little bit better, but it still makes for a very good and budget-friendly PSU series in it’s bracket. Especially when you look at the 500W market.

The Hyper K series also comes with Over Voltage, Over Current and Short Circuit protection and it comes with a 1-year warranty. Considering our electricity’s game of hide n’ seek, these features make it a very good selling point as well.

So in the end, we would like to rate the FSP Hyper K 700W PSU 9/10 and give it our Bang For Buck award! If you’d like to buy this PSU, visit Shingpoint.com
