Using an 800w Power Supply For Your Medical Device

When medical device manufacturers are shopping for a power supply unit, it can be an easy decision to choose medical-grade power supplies over commercial ones. Medical-grade power supplies need to abide by stricter standards and must be audited to meet multiple medical standards before going to market. However, another important decision when choosing a power supply is deciding what wattage level is necessary. 

We’ll talk about the considerations for 800w power supplies and share some examples of devices that use them. 

Should you choose an 800w power supply for your medical device? 

During the power supply selection process, medical device manufacturers should take into account both compliance and power requirements. Underpowered medical devices cause a major problem, but overcorrecting and getting more power than you need can also be wasteful and an unwise idea. It’s not uncommon to overestimate what is needed. The best way to know for sure is by having a conversation with the producers of the PSUs. They will be able to advise with the proper wattage needed and offer examples of other devices that were built with the same PSU. 

Other factors you’ll want to evaluate with medical PSUs include efficiency, durability, and noise level. What kind of guarantees are on the power supply units? How efficiently do they use power? How loud (or quiet) is the PSU, and how much will noise matter in your application? 

It’s also important to note that the wattage needed for your device and the requirements needed for the components are considered “max power” for the device. However, computers rarely run at max power for all of the components at once, leaving you some wiggle room for the wattage you may need.

What kinds of devices use 800w power supplies? 

It’s important to note that once PSUs hit the 800w range, there’s a fairly large jump that happens. Medical device manufacturers with needs around the 600-800w range don’t have many options to choose from. However, there are many devices that can benefit from these power supplies. 

In general, 800w power supplies are used in medical devices for things like endoscopic procedures, as well as real-time imaging and diagnostics. Graphics-intensive systems require support from higher-wattage power supply units. 

Examples of RAM’s 800w PSU in Medical Devices 

RAM Technologies has been happy to serve makers of medical devices that are in need of an 800w power supply. Examples of 800w PSU usage from our clients include the following:

  • Philips Core Precision Guided Therapy System: This system is capable of having three modalities on one platform – intravascular ultrasonography (IVUS), fractional flow reserve (FFR), and instant wave-free ratio / instant flow reserve (iFR). 
  • Iterative Health Skout: This medical device can help gastroenterologists identify adenomas while conducting a colonoscopy using artificial intelligence. 
  • Philips IntraSight Mobile: The Philips IntraSight Mobile conducts IVUS imaging and physiology. The system is designed to be easy to use and portable. 
  • Gentuity: This imaging system touts the world’s smallest catheter and is used to access and clear even extremely challenging lesions. The imaging needs to be ultra-precise and crystal clear. 

If you’re trying to decide whether an 800w power supply is right for your medical device, or you have other questions about PC-based medical power supply units, contact us. We’re happy to help!


RAM Technologies’ power supplies are 60601-1 3.2 certified and meet 60601-1-2 EMC standards. When you’re designing your medical device and need help with a PSU,  contact us for details.
