New PSU

Saul Farrell · 8 Aug 2020 at 18:15

So I recently got a great deal on a prebuilt which I then gutted, changed a few components and then built my own PC using the parts. One of the things that I didn't change was the PSU, but after speaking to some people on the sub they said that a PSU upgrade was needed. So, I currently have a Corsair VS650W that I'm planning on upgrading when the warranty runs out (sometime this october). For reference I currently have a ryzen 5 3600 and a RX 5700 XT. After looking at a PSU calculator my needs are around 594W but with the new GPUs being released which are rumored to be power hungry beasts, I think an upgrade to 750W might be necessary. So are there any suggestions for a 750W PSU that preferably comes from a reputable company and has a good warranty, that doesn't break the bank. I'm not really bothered about it being modular or not but that would be nice. Help appreciated!

That corsair PSU looks excellent, especially with that 10-year warranty! I've never had a modular power supply before (just built my first PC three days ago), does it come with all the wires that you need? SATA, Molex etc?

Yes both the corsair and Phanteks come with the correct cables and being modular use only what you need.

Both have a 10 year warranty.

That's at most 350W load everything absolutely maxed.
650W PSU will be plenty.

I do have 9 RGB fans, an RGB case (lian li o11d razer edition), a gaming keyboard, mouse and mousepad (all rgb) and several controllers in the back of my case...
As well as an AIO

Do those sound like PC is preparing to take off and fly out of window?
If not, they don't draw much.
Anyway with 3600 being really frugal CPU there's loose on that 350W.

Yeah there isn't really much need to upgrade now but I'm going to be getting a new PSU anyway and it makes sense to spend a bit more money on a 750W as I'm planning on upgrading my CPU and GPU when the new ones release later this year!

ok i'm going to stick an ore in ..
if you run a 650w psu at 650 w then your not saving anything and putting strain on it , as psu's are best run at 75-85%.. this is why i run a 850w

What are you running that uses 650w?

This cheap pre built is starting to look not so cheap if you end up replacing most of it. Personally id wait and see what comes out and at what power budget.

In what world does a system like that use so much power? What calculator were you using?

Ah

okay thank you for your help! I think I've decided on a 750W but I might go to 850W!

I use: https://outervision.com/power-supply-calculator
It was just the top one that came up. When I've put in all my specs it says the load wattage is 582W...+

Yeah, I was planning on waiting until the new GPUs come out anyway, I was just looking for recommendations in advance as my PSU warranty runs out in november. So far the only things I've replaced were the case and mobo, then I added some fans - most of which were hand me downs from a friend. So still a cheap PC nonetheless!
