PSUs above 800 Watts
Are you looking for a powerful power supply unit with over 800 watts for your gaming or overclocking PC? Then you've come to the right place! Our selection of Power Supply Units (PSUs) over 800 watts provides you with the optimal power supply for demanding systems, where highly overclocked components and/or multiple linked graphics cards in a CrossFireX or SLI setup operate. Find out here what you need to consider when buying a power supply unit and which features are particularly important.
Power supplies are the energy providers in computer systems. They convert the alternating current from the socket into direct current and transform the voltage to the values required by the PC components. The Power Supply Units (PSUs) over 800 watts are the right choice for extremely power-hungry high-end systems, where highly overclocked components and/or multiple linked graphics cards in a CrossFireX or SLI setup operate. For more detailed information, it's best to check out relevant hardware forums or contact the Caseking service hotline before making a purchase.
Various Features of PSUs over 800 Watts
Beyond the power output provided by a power supply, there are a few other points to consider before making a purchase:
- First, make sure that the power supply fits into the case being used. In addition to different form factors (SFX, Flex-ATX, PicoPSU), even the well-known ATX power supplies, especially in this extreme power class, can have varying depths. Therefore, you should measure in the case to see how long the power supply can be at most.
- Almost as important as the total power output of the PSU are the amperage ratings available on the individual rails. Especially graphics cards and processors require specific amperage values for smooth continuous operation. Some, particularly stronger power supplies, have multiple rails instead of a central 12-volt rail or split them up.
- The type and number of connectors of a PSU are also of great importance. Depending on the motherboard, graphics card(s), and the number of hard drives or SSDs, different numbers of ATX12V, PCIe, and SATA connectors are required.
- If you want a particularly tidy setup, you can also get a semi-modular or fully modular power supply ("cable management"), where some or all of the cable strands can be individually connected to the power supply housing.
- Nowadays, the efficiency of a power supply is more important than ever. The higher the efficiency, the closer the power that the power supply draws from the socket and the power it provides to the PC are to each other. The wattage difference is converted into heat. This means that more efficient power supplies are not only more energy-efficient but also run cooler and therefore quieter. The "80 PLUS" initiative tests power supplies (mostly at 115 V input voltage of the US power grid) and awards different certificates depending on the efficiency.
- Some particularly efficient power supplies that produce little waste heat also come in a semi-passive design in this power class, meaning their fan only turns on when the load and/or temperature makes it necessary.
- And of course, modern PSUs should have the most important protection circuits, such as overvoltage protection (OVP), overcurrent protection (OCP), or overload protection (OPP).
