Case Study: Sliger Designs

Case Study: Sliger Designs 

Sliger Designs, a maker of custom PC cases, needed a power supply that could meet the demands of its medical device customers: small, quiet, and powerful enough to run multiple GPUs. Sliger found the perfect partner in RAM Technologies, whose medical-grade PC PSUs are designed to power the most demanding applications.

About Sliger Designs

Sliger Designs is a company that sells a variety of custom-made IPC chassis, including desktop, rackmount, and wall-mount cases. Power supply units (PSUs) determine almost everything about their products. As customers look to make their devices as small as possible, producing as little noise as possible, they need to find a PSU that’s up to the task and can also run multiple graphic processing units (GPUs) or high-performance computing/field-programmable gate array (HPC/FPGA) cards.

Client Challenges

When Sliger was on the hunt for power supply units to use in their products, they wanted to find ones that were able to power high wattages that came with extremely high-performance image sampling – think artificial intelligence (AI), machine learning, and deep learning programs. These technologies require GPUs or other Tensor Core accelerators, such as H100, A100, A2, L4, and so on. The power requirements for CPUs are also exponentially increasing. 

They also wanted to find PSUs that were as small as possible. Since Mini-ITX is no longer a viable form factor, most motherboards they support are FlexATX or MicroATX at minimum. Most requests for quotes (RFQs) are for ATX or even custom form factor server boards. 

Results After Working With RAM 

Before deciding to work with RAM Technologies, Sliger reviewed two other companies that specialized in medical-grade power supplies. They ultimately decided to work with RAM because we were able to remove a common pain point that often exists between developer and manufacturer. 

Sliger was struggling to reach engineers at other companies, instead getting punted to salespeople who only sent spreadsheets and couldn’t answer specific questions. Many other companies also had minimum order quantities (MOQs) that “made it impossible to prototype or develop new products,” said Kahlin Sliger, Product Line Manager for Sliger Designs. 

The medical-grade PC PSUs from RAM Technologies have allowed Sliger to have a smoother go-to-market process. “I am not stuck designing for stuff that is insanely out of date or a convoluted mess of single voltage components,” said Sliger. 

Right now, RAM’s high-power SFX PSUs can help Sliger satisfy the RFQs coming in. Our PFC650SFX power supply was designed with Sliger’s collaboration to satisfy a need that wasn’t being met in the market.RAM Technologies was able to supply Sliger Designs with a drop-in PSU that worked for their medical device. We offered cables at the right lengths so no excess cable would take up space within the case. RAM also provided a custom 5V barrel jack to power an off-the-shelf component. 

As high-performance computing demands go up, Slider expects more demand for high-wattage units to power multi-GPU units, FPGA cards, and more.
