Comparison
How This Compares With the Alternatives
| A supply labelled only with a peak figure | Rated power 450W peak power 550W are published as separate rows so the comparison is honest. |
|---|---|
| A supply with no published rail table | Per-rail maximum and minimum load, regulation and ripple are all published, which is what an engineering sign-off actually needs. |
| A standard ATX unit in a slim or rack chassis | The mechanical envelope is stated as 150x86x160mm (WxHxL), 14cm Fan, so the fit check happens before the purchase order. |
Use Guide
Checks to Run Before You Place the Order
- Total the +12V draw of your board, drives and graphics card against the published maximum load of 25.0A 20.0A 18.0A 18.0A 0.3A 2.5A
- Compare the unit envelope 150x86x160mm (WxHxL), 14cm Fan against the power supply bay of your chassis
- Confirm the destination mains voltage against the published input voltage range before ordering
- Leave depth behind the unit inside the chassis for the cable exit
- Quote the rated power rather than the peak power in your own product listings
ATX 450W 500W 550W 600W 80 PLUS Computer Power Supply Questions
Is 450W the real continuous output?
Yes. 450W is the rated continuous output and 550W is the peak. Both are listed separately on the specification table on this page so there is no ambiguity in your quotation.
What is the load capability on each rail?
Maximum load is 25.0A 20.0A 18.0A 18.0A 0.3A 2.5A across +3.3V +5V +12V1 +12V2 -12V +5VSB. Minimum load is 0.3A 0.5A 1.0A 1.0A 0.0A 0.0A. Send your target board and graphics card and we will check the +12V budget with you.
Will this unit fit our chassis?
The mechanical envelope is 150x86x160mm (WxHxL), 14cm Fan. Compare it against the power supply bay of the chassis, including the space needed behind the unit for the cable exit.
What certification evidence is available?
CE EMC and CE LVD certificates are held for the power supply line and the certificate images are shown on the About page. Ask us on WhatsApp for the full certificate files for the specific model you are quoting.
Can the unit be supplied with our own label?
Yes, private-label printing on the unit and on the colour box is a standard option. Send your artwork and we will confirm what the printing area allows.
What is the minimum order quantity and lead time?
Both depend on wattage, cable configuration and packing, so we confirm them per order rather than publishing a single figure. Message us the model and quantity for a written answer.
