Corsair VS450

Cooler Master Thunder 450W

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.


All these above mentioned PSUs are budget range power supplies and all are rated at 450 Watt power output. These are high quality power supplies and are meant for users who are on budget but want good performance at lower price.
