HP Power Supplies
If you own a HP brand computer then you know doubt want to know the benefits of HP power supplies. These brand specific PSU’s used to be an object of constant torment and pain for those of us in the IT industry. However stiff competition and years of development have allowed HP to finally develop a line of good power supplies that are very capable and reliable.
In the past the reason most technicians had to hate HP power supplies was their odd shape and low durability. A power supply has to have enough power to support and expand the system. Most of these earlier models just covered the support part barely. Expanding an early HP machine was very difficult and low power components weren’t on card manufacturers minds at the time.
Add to the fact that their shape was unique and only allowed them to be fitted in HP cases and you had a real annoyance for system builders. However times have changed since then and the quality of the PSU’s produced by HP has improved significantly. They have learned that not only do you need to make the unit powerful, but it needs to have the ability to keep up with technology as well.
Most newer HP power supplies have increased wattage capacity, additional voltage on the 12 volt rails and more plugs than their ancestors did. Add to the fact that the units shape is now normal with no special clamps or fixtures and you have a PSU that’s worthy for any machine. However their most impressive feature is their energy savings capability.
Servers are an important part of our world and HP power supplies have been designed to keep these backbones of our society running. But just because their running doesn’t mean that they can’t run efficiently. That being said HP offers a variety of different wattage units for different server load classes. Many of these units are rated at 90% energy efficiency or higher.
This might not mean much to most people but it is very important for technicians and builders. A typical cheap power supply that one might get with their computer is extremely wasteful. When a power supply such as a 300 watt is running at 295 watts it is not very efficient. While it can run like this safely the power it’s getting from the wall is being wasted.
Simply put traditional low end PSU’s use about 60% of their power and waste 40% of it in heat generation. However you can increase the efficiency by adding better components and increasing the capacity of the unit. Contrary to popular belief a 500 watt PSU does not draw 500 watts from the wall immediately; it simply has the capacity for 500 watts. If it’s only being taxed by 400 then it can run at about 85% efficiency which means only 15% of its wall power is wasted.
HP power supplies have come a long way from what they used to be. They are now very competitive in the industry and very efficient. This has led many to have renewed trust in their systems reliability. With being rated at 90% efficiency these units are gathering a lot of attention both in the professional world and the private.
