Question How much Power do I really need?

[NAVY_108]

So I want to get a new psu, since my old one was always constantly turning off for no real reason. I don't really want to spend too much on a power supply, however, so I need some tips. Say if there is enough connectors for everything I need, does that mean it is enough power? If not, here are my specs:
MB: hp elitedesk 800g1 sff
PSU: Undetermined
Cpu: Xeon e3 1220 V3
Cooler: Stock
RAM: 8gb ddr3
gtx 770 2gb gddr5
2tb 7.2k rpm HDD
256gb (I think) PM851 samsung SSD
5 ~1200 rpm fans
I was thinking if a 550w psu would be enough.
Thanks!

Model name?

But it really doesn't matter since buying used (refurbished) PSU is a bad idea. With used PSU, you have no telling what kind of abuse it saw previously and even with official refurbished PSU, the PSU brand, in this case: EVGA, doesn't trust it to last long, giving it measly 1 year of warranty. Though, funnily enough, your "new" EVGA BR also has 1 year of warranty, even when brand new. 🤣

On the contrary, suggested Seasonic Focus GM-650 has 7 years of warranty. So, there's that.

I just don't want to spend money unless I am sure that is the case.

Without replacement components, you can't test and tell for sure if that is the case. And replacement parts cost money, unless you can loan it from somewhere.

Edit:

I now see my error. I read model defining suffix as model name.
BR series has K1 suffix, meaning that it yes, has 3 years of warranty. 😊
My bad.
