For Compact PC Builds

evga supernova 750 gm
  • 750W
  • SFX form factor
  • 80 Plus Gold certified
  • Fully modular

Not everyone wants to build a full ATX PC but all PC configs need a PSU, so to cater to this group of people that need smaller form factor power supply units, EVGA created the SuperNOVA 750 GM.

This is a 750W, 80 Plus Gold certified, SFX form factor PSU that uses Japanese capacitors to ensure reliability during loads. Since this is intended to go in a PC that has space limitations, the PSU is fully modular to accommodate routing your cables easier, and a fluid dynamic bearing fan to keep your build silent.

The PSU comes with a 10-year warranty, but considering the track record of EVGA and its overall quality when releasing products, this PSU can outlive its warranty in most cases.

  • Small but mighty and built with quality components
  • Full modularity is even more important in a small form factor build
  • Has smart features like auto ECO mode to lower the noise levels
  • Is reliable even with power-hungry components that are tucked away in a small case
  • SFX power supplies will generally cost a bit more since the manufacturer needs to cram a lot of parts in a smaller shell

Seasonic Prime 700 Fanless TX

Extremely Reliable Fanless PSU

seasonic prime 700 fanless tx
  • 700W
  • 80 Plus Titanium Certified
  • Fully modular
  • Fanless design

If you are building a high-end ultra-quiet system then you cannot forget that the PSU is also a source of fan noise. To ensure that this does not become a problem for your specific build you should invest in a fanless PSU.

One of the best options for this purpose-built system would be a Seasonic Prime Fanless TX PSU. As expected from any Seasonic power supplies the quality of this product is extremely high ensuring the proper operation of your PSU and other components even without needing a fan.

This specific unit is 700W and is 80 Plus Titanium which means it is even more efficient than Gold rated PSUs. This is the main reason this specific unit can run without a fan – since less energy is wasted, less heat is produced, therefore, the fan is not necessary.

The Seasonic Prime 700 Fanless TX is also impressive because it has micro tolerance load regulation that ensures a great deal of stability therefore can be used even in high-performance systems that will be under heavy loads.

The cherry on top is the fact that this PSU is fully modular and allows you to get rid of extra cable clutter.

  • An extremely high-quality PSU
  • Fanless operation for extra quiet systems
  • Seasonic offers a 12-year warranty
  • The 80 Plus Titanium Efficiency will ensure that the PSU is cool even without a fan
  • Silence is costly since the PSU is around 300$

How To Choose A Power Supply

how to choose a gaming power supply

Yes, picking a power supply is as exciting as watching paint dry. But you’ll have to consider several things before you find the perfect power supply for your needs. The road to the best power supply is relatively short but it features a couple of nasty potholes you should avoid.

Calculate The Power Output You Need

This is the first thing you should do. You need to have a clear picture of how much power you need. The OuterVision Power Supply Calculator is an excellent PSU calculator that offers a wide selection of components. Once you calculate how much power you need, add about 50 W more, just in case.

Make Sure To Include Future Upgrades

PSU isn’t a component we change regularly so it’s best to include future upgrades into your power calculation. Because chances are, you’ll have the same PSU for years and years.

The best way to do this is to select CPU and GPU that use more power than your current choices, to introduce a couple extra SSDs to the calculation, to add more RAM sticks. You get it.

Continuous Power Isn’t The Same As Peak Power

Most PSU manufacturers advertise peak power as their rated power. For instance, a 500 W PSU is capable of providing a peak power of 500 watts but only for a short duration. Its continuous power is probably around 450 W.

This is why it’s important to get a power supply that is capable of delivering more power than you need. If you need, for instance, 400 watts of power go for at least 500 W PSU.

Make Sure That The PSU Has 80 Plus Certification

The 80 Plus certification program is the most popular way to rate PSU efficiency. If a PSU doesn’t have at least 80 Plus Bronze certificate, don’t even consider it. The great middle-ground are power supplies with 80 Plus Gold certification.

Those with 80 Plus Platinum stamp are extremely efficient. And, to be honest, the 80 Plus Titanium rating is mostly for bragging rights. You don’t actually need something as efficient as that. Below you can find the full 80 Plus rating system:

Make Sure The PSU Fits Inside Your Case

Not all PSUs measure the same. There are 2 main form factors: ATX and SFX. An ATX PSU should fit inside all mid, mATX, and full tower cases. SFX form factor is made for small form factor (m-ITX) machines. Remember that if you want to build a small form factor PC.

SFX power supplies can fit into regular PC cases but this isn’t recommended. Their cables are shorter and you won’t be able to reach your components if you place a SFX PSU into a regular case.

Finally, Make Sure The PSU Has All Connectors You Need

The last thing you should consider are connectors found on the PSU. You should find all connectors listed in official specs of any PSU. Your motherboard needs either a 20-pin or 24-pin connector. Your CPU power connector comes in 4-pin and 8-pin flavors.

The graphics card is using 6-pin and 8-pin connectors. Finally, there are 4-pin Molex connectors and SATA power connectors. Remember that you can use splitters to connect additional components, just remember to not go above your PSU power limit.
