The Cooler Master Thunder M 620W has a suggested retail price of only Php 3,199. That’s the cheapest modular PSU I could find in Philippines. There are other competing brands like Seasonic which is priced similarly, but it’s only a 500W PSU or more.

If you are on a budget but would want to get a modular PSU, you definitely would want to consider this one, considering its price. With a 620W modular power supply, you can build an entry level to mid level gaming PC already.

  1. May 700W/750W model ba cla nito? mura na ng price compared to others.

    1. For the Thunder M Series only 620W, 520W and 420W. They have 700W or 750W but they are on a different series. However I noticed that the Thunder M doesn’t have 80 Plus certification.
