First time PC build - UK lockdown induced PSU Advice

Onthejourney · 1 Dec 2020 at 13:26

Hi All - first time PC build and was wondering if I could get some advice regarding the PSU

MSI MPG B550 Gaming Plus (AMD AM4) B550 ATX Motherboard
MSI GeForce GTX 1660
Ryzen 5 3600 CPU
16GB DDR4 RGB RAM
NZXT H510i Midi Tower
2 M2 NVME SSD (1x 500gb for boot and 1x 2tb)

I will primarily use my pc for browsing internet, watching films, running various programs. I will use it throughout the day and after work would like to play online games. Currently, I do not plan to edit 4K videos or things of that nature but may sometime in the future test the waters with youtube videos.

I came across the Corsair RMX550 which seemed to be well regarded? - reviews highlighted there is no fan test button and noted the distance between 4-pin Molex connectors. Not sure if this is a big drawback?

I have used the Seasonic calculator and had a look on their site, but like all the major companies, there are so many models they sell it difficult to choose. I don't want to scrip and was looking for the unit to be modular and have a 80+ Gold rating. Does anyone have any suggestions for that is available on the market? Thanks

Take a look at the Tomahawk.

Molex connectors aren't really used these days.

550W will be more than enough for your build. Just be prepared to upgrade your PSU if you upgrade the GPU or CPU.

Thanks - but do you mean the Tomahawk 450 or 550

Ask & you shall receive.

My basket at Overclockers UK:

1 x Seasonic Focus GX-550 550W 80+ Gold Modular Power Supply= £87.95

Total: £98.45 (includes shipping: £10.50)

The phanteks amp version is a couple of quid cheaper & is virtually the same model. Sometimes it is best to buy a make where its made by themselves & not a make where its made for them. Corsair used to be the latter. When they started out they were very good, went down a bit & then got back up again.

Appreciate this and the background info on the models that Seasonic also manufacture - thanks

Thank you - but suppose I were to change CPU to a Ryzen 5 5600x keeping rest of build, would wattage would I need?

No difference.

If you want some headroom, step up to 650W, if you're going for gold rated(and Seasonic) they're shouldn't be much if any cause for concern.
