If your rumah never once kena petir and hancur barang dlm rumah electronic saya rasa tak perlu risau, voltage regulator pun juga perlu tukar setiap 5 tahun kalau tak silap sebab dalam ada satu material/alat yg buat kerja tu akan lost effective over time

Surge protector pun tak sangat mahal up to you want or not, i punya PC duax2 pun tak ada , lepas 8-10 tahun tukar PC jer tak perlu risau pun 😂

Tq boss you really helping me much ahahhaa

Im using KOSS brand now, no fan. Previously using AVF which has a fan and very annoying when I not using audio.

Im not familiar Targus or Tessan.

Downside to UPS is you need to replace the battery every few years, about RM50 a pair depends on size. It will still be the cheapest thing you need to replace on your PC if things go south.

And when that happens it really depends on your location, if never have lighting surge or power cut, then its not needed but for those rare occasions it helps to save your PC and data. However these just for supporting your PSU, if its too old or too limited its time to go will be sooner.

Hahaha samax2

If i wanna up gpu so need use this ups eh boss? For better okok will consider ups like tessan o targus read the review they said good

I think its a bit out of topic. If you wanna up GPU to 4070 its not necessary to change your PSU. But regardless whether you keep use the 3070 or next 4070, getting a UPS is a good idea to prevent your PC life from dying due to power related issues.

Thanks i learn something today tq again
