[SOLVED] How much of a PSU do i need?

[Wilhem991]

I am about to finish my build. Some of my friends suggested 650W is not enough and that i should go for 750W

Parts i am gonna use are:
CPU: Ryzen 5 5600x
RAM 4x 8gb ddr4 3600mhz (non RGB for now but possibly RGB later)
MBO: Asus ROG strix B550-F
Memory: 1x M.2 250gb, 2x SATA ssd, 1x 7200RPM HDD
GPU: RTX 3070 (for now GTX 960 till prices drop so possibly amd equivalent to it dependable on price)
Case: Corsair 4000D airflow
6x ARGB fans with fin LED and ring LED

I was thinking about 650W modular PSU 80+ Gold

thanx in advance.

Should be enough but good make and model as many falsely advertise power. Gold rating doesn't guarantee it's good.

I’m running a high quality 650w with a 3700x (PBO on) and an RTX 3080. A 650w is plenty for your system but 750w might be nice for future upgrades.

As CountMike points out Gold is not a rating of quality, there are bad Gold PSU’s.

This one is in my mind.

Think it is A tier PSU as far as i understand sheet.

Probably there will not be future upgrades for next 5 years. I game on 1080p and this should be good enough for next 5 years than i will replace whole pc again.

Buy the memory in a 2X16GB set.

Be aware there is no guarantee this will work.

Here is a handy chart for sizing a psu.
It depends mostly on your graphics card.
For a 3070 the chart shows 600w,
http://www.realhardtechx.com/index_archivos/Page362.htm
But, be advised that some 3070 cards are factory overclocked and need an extra 8 pin
(mine does) so I think 750w would be minimum.

I have no problem overprovisioning a PSU a bit. Say by 20%.
It will allow for a stronger future graphics card upgrade.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.
I would have no problem with 850w.
You will often find a minimal price difference between 650/750/ and 850w.

Ryzen is very sensitive to ram; not all ram will work.
If you now have 8gb, go ahead and try it.
But if you need more, buy a supported kit.
Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
The internal workings are designed for the capacity of the kit.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards, can be very sensitive to this.
This is more difficult when more sticks are involved.

Nice case.

If you already have a m.2, 2 ssd, and a hdd, then ok.
Otherwise, I would have fewer/larger devices and use a HDD as external backup.



If you want to try adding ram, see that you can return it if it does not work properly.

I concur about the about psu price difference. I’m from the USA, but when I upgraded my psu, I think the seasonic 650 Focus gold units were something like 119 dollars. My Corsair rm850x cost about 150. A few dollars more but 10 year warranty and overpowered for my needs right now should last a couple of upgrade cycles.
