You need the right computer server power supply for your work. This quick guide helps you pick what you need:

Pick your computer server power supply by your work type for the best results.

Hal-hal Penting yang Dapat Dipetik

• Pick a power supply that fits your workload. Small businesses need a 500W to 650W unit. High-performance computing needs 1600W or more.

• Get a power supply with 20% to 30% more wattage than needed. This helps your server work better. It also lets you upgrade later.

• Check for 80 PLUS certifications for energy efficiency. Higher ratings like Platinum or Titanium save electricity. They also help your server stay cool.

• Think about redundancy for important servers. Redundant power supplies stop downtime. They keep your server running if one fails.

• Take care of your power supply often. Clean out dust and look for damage. Listen for strange sounds to keep it working well.

Choosing a computer server power supply

Wattage and sizing

First, look at your server case. Check if it fits the right form factor, like ATX or SFX. Figure out how much power your server parts need. Add up the power for the CPU, GPU, drives, and fans. Use this formula: Watts equals Amps times Volts. Pick a power supply unit with 20% to 30% more wattage than you need. This extra power helps your server work well and lets you upgrade later. For example, if your server needs 500 watts, get one with at least 650 watts. Make sure your power supply unit has enough connectors for your motherboard and graphics cards.

Tip: Spend about 10% of your system cost on a good power supply unit. This helps you avoid problems that can stop your server.

Efficiency ratings and certifications

Efficiency helps save energy and keeps your server cool. Look for 80 PLUS certifications when you buy a power supply unit. Gold is good, but Platinum and Titanium are better. These ratings show how much power your server uses compared to what it gets from the wall. Higher ratings mean less energy is wasted and your electricity bill is lower.

If you pick a higher efficiency rating, your server will stay cooler and last longer.

Reliability and redundancy

Reliability is very important for servers. Enterprise-grade power supply units can last 100,000 hours or more. If your server is mission-critical, you need redundancy. Redundant power supplies keep your server working if one fails. This setup removes single points of failure and helps your server stay online. You can use N+1 or 2N redundancy for more safety. Try to connect redundant units to different power circuits.

Note: Power and heat often cause server problems. Redundant power supplies and good cooling help stop downtime.

Server power supplies for different workloads

Light workloads: small business, file servers

Small business and file servers can use one good power supply. Pick one that gives between 500W and 650W. Try to get 80 PLUS Gold or better for efficiency. This saves energy and keeps things cool. Choose a model with strong parts and good ratings. If you want extra safety, use a redundant power supply.

Servers often have backup power supplies for uptime. If one fails, the other keeps the server running. This helps stop downtime.

Small offices do not always need backup power supplies. But it helps if your business needs files all the time.

Web hosting and application servers

Web hosting and app servers need stronger power supplies. Choose one between 650W and 800W. Focus on efficiency and backup power. Hot-swappable units let you change them without turning off the server. This keeps your website or app working.

Pick power supplies with these features to keep your services up and your users happy.

Virtualization and high-density servers

Virtualization and high-density servers need a lot more power. Pick power supplies with 1000W or more. Backup power is a must. Use hot-swappable, modular units for easy fixes. High efficiency, like 80 PLUS Platinum or Titanium, saves energy and cuts heat.

Virtualization servers run many virtual machines. This uses more power. High-efficiency power supplies help save energy and lower costs.

Storage servers and NAS

Storage servers and NAS need special power supplies. The right one depends on how many drives you have and if you want backup power.

1. For simple NAS with a few drives, use a 300-400W power supply.

2. For bigger NAS with many drives and RAID, pick a 500-600W power supply.

3. For fast NAS builds, get a 700W or higher power supply.

• Do not use more than 80% of your power supply’s limit. This helps it last longer and work better.

• For NAS, add up all the power you need, including about 25 watts for each drive to start up.

• Backup power is important to stop the whole system from failing if one power supply breaks.

• Good parts in power supplies stop problems like voltage drops and power loss, which can hurt storage parts.

Power supply efficiency matters for storage servers. It affects how much you pay at first and later. Better efficiency means you use less energy. This lowers your bills and cuts down on repairs over time.

High-performance computing and GPU servers

High-performance computing and GPU servers need the most power. Match the power supply to your GPUs. For example, each NVIDIA H100 GPU can use up to 700W. An 8-GPU server might need 5.6 kW just for the GPUs. With CPUs and other parts, the total can be 10 kW or more.

• Modular power supplies make upgrades easy and cut downtime. This is important for high-performance work.

• Smart telemetry in OCP power shelves lets you watch power use in real time. This helps you fix problems before they get worse.

• Hot-swap power supplies let you change them without turning off the system. This helps in busy, high-power places.

Always use backup, high-efficiency power supplies in these systems. This keeps your hardware safe and working well.

Installation and maintenance tips

Installation best practices

You want your server to work well and stay safe. Pick a power supply that fits your server’s needs. Put the power supply in a clean and dry spot. Make sure it fits the server case and has the right plugs. Use a strong power system to share power with all devices. Add backup batteries or an catu daya tak terputus for outages.

For more safety, use redundant power supply units. Connect each power supply to a different circuit. This keeps power sources apart. If one circuit stops working, the other power supply keeps the server on. Using different circuits lowers the chance of both power supplies failing together.

• Put the power supply where air moves easily.

• Fasten all cables so they do not come loose.

• Check that each power supply is in place.

Tip: Label every power supply and circuit. This makes fixing problems easier later.

Maintenance for reliability

Taking care of your power supply helps it last longer. Clean dust from fans and filters so they do not get too hot. Keep the server room between 68°F and 77°F. This keeps your power supply safe from heat. Use an uninterruptible power supply to protect against surges and outages.

Look at your power supply for signs of damage. Change any broken power supply right away. Test backup batteries for swelling or rust. Watch each power supply to find problems early. If you see voltage changes or hear odd sounds, fix it fast.

• Clean fans and filters once a month.

• Look at cables and plugs for damage.

• Test backup batteries often.

Monitoring and troubleshooting

Watch for signs that your power supply might fail. You may hear strange sounds or see voltage spikes. Too much heat can make fans slow down. Look for bulging parts or color changes inside the power supply. If your server crashes or shows blue screens, check the power supply first. If you smell burning, turn off the power supply and check it right away.

Note: Acting early can stop bigger problems. Always keep a spare power supply ready to swap in quickly.

Pick a server power supply that fits your workload. High-efficiency units help your server work well. They also lower energy bills and make less heat. Always look at power, efficiency, and backup options for your needs.

• High-efficiency power supplies stop problems and save money.

• Certifications like 80 PLUS show good performance.

• Backup units keep your server working if something goes wrong.
