Antec VP450P

Corsair VS450 is a very popular and affordable budget range SMPS. I have written a detailed review of Corsair VS450 PSU which you can find below.

Cooler Master Thunder 450W is also a very good budget power supply from Cooler Master. It is also quite popular and is a close rival of Corsair VS450.

Antec is a company that is known for making high quality power supplies and computer cabinets / PC case. Antec VP450P is one of the best budget power supplies which is a little difficult to find in India, because it is not as much popular as compared to its rivals.

Final Words & Conclusion

Well as we can see from the above table that all these budget PSUs are alike in various aspects.

It also has dual 12V Rails having current of 21A and 18A respectively. The most economical of the three PSUs is Corsair VS450 which is also very popular among buyers. Antec falls between Corsair and Cooler Master on the basis of current on its 12V Rail, but from my side it is the best SMPS among the three. Antec is very good brand and is known for its high quality power supplies in the world and has the best reputation in the power supply department. At last I would like to say that all three PSUs are good and you can choose any one of them according to your need and budget, but if you want the best one then go for Antec VP450P.
