Testing Results

We used a KillAwatt to get the voltage drawn from the wall and a Fluke 276 clamp meter with 18 inch flex current probe, we used a simple infrared thermometer to get thermal exhaust and a Decibel Meter App for noise.

Operating at an average efficiency of 89% from 10% to 100% load these are consistent numbers we love to see. 10% isn’t even counted on the Gold / Silver / Bronze rating scale, they start counting at 30% but if you run a low power system you need to know the lower voltage ratings.

Not only did the CoolerMaster V750 hit it’s target efficiency rating, it went above and beyond across all load ranges. Even under 100% load maxed out to core the V750 still delivered a 88% efficeincy rating. Given that your rig shouldn’t be pulling more than 75% of the rated load optimally, these results show you can expect to get proper performance from your investment even when pushing it to the absolute max. The CoolerMaster V750 is not very far off from platinum efficiency numbers.

The Steam Deck – Valve delivers an excellent PC handheld

Valve is an interesting company that seems to try to be a lot of things at the same time. Games company, software hub/store and hardware company. Valve is all of these. When it comes to hardware the company has had mixed success. I think many of us remember the Steam Machines. These compact computers running SteamOS, a Linux based OS, were supposed to make Windows PC’s obsolete for gaming. They didn’t succeed. Valve also released a specific controller, the Steam Controller, which also did not exactly set the world on fire. In hindsight though both these products have paved the way for the product I am testing today, the Steam Deck, Valves attempt to compete with the Nintendo Switch in the handheld market.
