So you just upgraded you system and realized that you forgot that your little power supply can’t produce enough juice to power your system to the full, what do you do? Well you could try getting a bigger power supply which in the end is what you’re going to have to do anyways. So now that you got a bigger power supply you find that it’s to big for your case and that once again you have to make another forced upgrade. Well with the Nexus RX-1K 1000 watt PSU you don’t need to worry about that inconvenience. With this handy little power supply you get the silence that most nexus products are known for, combined with a modular 1000 watt power supply no bigger than a standard sized PSU. Let’s take a closer look at this tiny powerhouse:
Product Provided By: NexusPrice: $199.99
Closer Look:
Let’s move on to the specs and features:

- Stable, solid and versatile....
Features:
Energy Efficient
The Nexus RX-1K power supply is guaranteed to provide you with over 80% efficiency (see graph elsewhere on this page). This means the power supply is using the power it is drawing from the wall outlet more efficient and less electricity is wasted. Obviously this is better for the environment and it saves you on your electricity Bill! A more efficient power supply also results in a cooler power supply. So less cooling is needed and we are able to make the power supply even quieter.
Silence
By carefully selecting each component we aim at creating the best possible of mix of components to make our power supplies as silent as possible. We are confident that our power supplies are leading the market when it comes to solid performance at the lowest possible noise level. When we test the noise level we do this in a ISO-certified chamber for noise tests. It is important to know that the background noise in such a chamber is a little over 15 dB(A). These are the best possible conditions for these tests and hence you should always be aware when a manufacturer is claiming dB(A) values lower then 15 dB(A). Because how are they able to measure this.
Modular & Sleeved Cables
Messy Cables interfere too much with the airflow inside your PC. The modular cable design allows you to only connect the connectors you really need. Plus all cables are sleeved with a quality black mesh for a clean good look.
Active PC Circuit
Power Factor Correction (PFC) allows the power distribution system to operate at maximum efficiency. This does not so much influence your electricity bill but it will also reduce energy consumption at the side of the power provider so it is contributing to using our planets resources better and more carefull. Active PFC is technically more complex then passive PFC and matches the overall high quality standard and reliability of this Nexus power supplies.
Full Range Automatic
This power supply can be used on 115VAC and 230VAC input power. Selection is automatically made no voltage selection has to be set. Just plug in and go.
Now let’s plug this in and do some testing:
Testing Setup:
- Asus P6T SEX58 Motherboard
- Core i7 920 CPU
- 6GB Crucial Balistix 8-8-8-24 1600mHz
- Asus EAH 4850
- 750 GB Seagate Barracuda
- Vista Ultimate 64bit
- Inwin 850 Commander Series PSU
- EAH 4850
Testing:
For testing I will be doing a few standard tests. First I will connect a LCD power supply tester before I connect it to my PC. Next I will record the voltages while it runs idle and then under load, which will be achieved by running the Prime 95 burn-in test. The idle and load numbers will be regulated by the on board motherboard sensors. I will be testing the Nexus RX-1K 1000 watt PSU against the Thermaltake Toughtpower 750 watt PSU.
LCD Tester
| PSU | Nexus RX-1K 1000 watt PSU | Thermaltake Toughtpower 750 watt PSU |
| +5 | 5 | 4.9 |
| +12 | 12.1 | 12 |
| +3.3 | 3.3 | 3.3 |
| +-12v | 11.6 | 12.2 |
| +12v2 | 12 | 11.8 |
| 5vsb | 5 | 5 |
| PG | 270 ms | 280 ms |
Idle / Load Voltages
| PSU | Nexus RX-1K 1000 watt PSU | Thermaltake Toughtpower 750 watt | ||
| State | Idle | Load | Idle | Load |
| +12v | 11.40 | 11.40 | 11.35 | 11.35 |
| AVcc | 3.36 | 3.36 | 3.33 | 3.33 |
So from these we can see that both of these PSU are very good and stable under load and idle conditions, and we can see that all the rails are producing the proper power that they should be which makes both a great option. With the Nexus RX-1K 1000 watt PSU however you still get a lot more power, it is at least partially modular which helps clean up the case and makes cable management a lot easier.
So let’s move on to my final thoughts:
Conclusion:
In the end I really like the Nexus RX-1K 1000 watt PSU. While its price is a little on the high for some, most looking for a good gaming PSU know that with great power comes some cost. Don’t let this detour you though, this is still a great PSU. From the tests we see that this little guy didn’t even fluctuate under the stress of the burn-in, and that all of the rails produced the proper amount of power, within acceptable fluctuations.
Another great thing about this unit is its size. Because of its size, which is no larger than a normal sized unit, I could easily fit this in the B-gears B-Envy Micro ATX Chassis with no problem. One last thing that kept slipping my mind is that as with most Nexus products, at least with all the ones we have received, this PSU is net to silent which in my opinion is always a great thing because most PCs a loud enough and don’t need that additional noise from a loud PSU.
So would I recommend this PSU? Well if you’re looking for a good large power, all round solid gaming PSU then yes. For those looking for a new or those looking to replace their old gaming PSU this might be a good option. With its solid power capabilities, partial modular design, and the fact that it’s a 1000 watt PSU that doesn’t jump to a larger size unit just makes this an ideal choice for those that are looking for a large PSU but have some space constrictions.
Pros:
- Solid power
- Partial Modular
- Small for its power class
- Looks nice, gun metal finish
- Near Silent
Cons:
- None that I can think of
