Top 850 Watt Computer’s Power Supply Unit

Report Data Collected On: 1/Jan/2019

With GPUs taking up most of the attention, PSUs are often overlooked and sometimes users end up picking a PSU which does not adequately meet their computer’s requirements. This leads to a whole range of problems including the fact that the wrong PSU may even lead to a fried GPU.

While the power rating plays a role, it is important to get a high quality PSU which will last longer and minimize the risks of damage to the PC components. Here’s why I recommend investing in a high quality PSU:

  1. Does not damage the PC: The biggest advantage of a quality PSU is that it safeguards the PC architecture from unwanted damage by supplying stable power, adequately to the components. This is especially the case when you are using high-end video cards or when you are using the PSU in a gaming PC.
  2. Minimizes power bills: All PSU rated 80 Plus will help you considerably reduce the amount of power lost to heat. If you have a powerful PC then you will be able to notably reduce the power bills using the right PSU.
  3. Easier to upgrade: High quality PSUs and oversized PSUs will not only help in the above ways, but also ensure that future upgrades do not require a change in the PSU. You can easily upgrade other components in the PC with fewer worries about the PSU.

Short ReviewFor many, Rosewill may not ring a bell. However, this is a great PSU to invest in if you are looking for a good quality PSU at a reasonable price. Given its affordable price, the Rosewill Glacier 850M PSU performs very well.

It does not have a very fancy look but that is hardly a concern for a PSU. The fan is very quiet which makes it easy for you to enjoy gaming or work on the PC without having to worry about a noisy fan humming in the background.

The aero-diversion design for the fan is also an advantage since it keeps the PSU cool. This 80 plus Bronze certified semi-modular design PSU model comes with lots of cables that make it easy for you to connect it with modern gadgets and components.


• Very reasonably priced. Is a great PSU for those who are on a budget.
• The performance of the PSU is worthy of the price you pay.
Extra cables make it easy to use additional components without having to buy extra cables.
• The connection rack system is easy which makes installation simple even for those who are using it for the first time.


  • A few users found the 8-pin connector to have a relatively shorter cable which made it difficult for them to use it properly. But this is not something that cannot be fixed with an extension.

Short ReviewIn The Focus series is a notch lower than Seasonic’s Prime PSUs. They are available in a range of capacity points and are priced reasonably. The aim of the Focus series is to bring affordable and high performing PSUs to the market. The model in discussion today is the 850W model which is an 80-Plus gold and has received S++ ratings from LAMBDA.

The strong build quality and superior performance of this PSU makes it a better choice than others in the market at the same price range.

It comes with six PCIe and two EPS connectors which make it easy for users to connect it to high end PCs too without having to worry much about compatibility. Many builders will also find the semi-passive mode to be an advantage since users have the option of turning this mode off so that they can enjoy quiet operation. That however, does not mean that the fan is very loud. On the contrary the fan works very quietly.


• Great PSU for budgeted users looking for high quality build and performance.
• Excellent ripple suppression.
• Fully modular model.
