Psu setup for new build

[ColetonPoole]

Sorry if this is in the wrong placement, but I have parts I've acquired and had previous build. I don't want to spend money on a new PSU, I have a add2psu on the way. My case is a Corsair 900D with 2 power supply mounting locations. 

 

I have a cx450,cx650m (missing modular SATA cable), and tr2500 (thermaltake that I got on sale for RadioShack going out of business locally a long time ago lol, lots of ware).

 

Without getting to far into it, I was wondering if my 450 watt could power my 5700x on a b550 eagle WiFi 6 (full atx). CPU is air cooled with 2 120mm fan, 6 120mm case fans, rear is a 140mm. 8gb ddr4 3600 (2 sticks, 16gb total).

M2 nvme 1tb. Have 1 hdd 7200, but may add another. Also 2 DVD drives, but don't really need them. 

 

This way I could you my 650 watt for a GPU upgrade? Thanks!

Which GPU are you going to use?

Right now I did some wheeling and dealing and got rid of my 1660 to 6gb and downgraded to a 1060 6gb. 

 

And whatever the used market floods me with or a good deal lol. Want a good match for my 5700x! Just want to be best ready for it

the 5700X uses max 65W (not quite sure about that, could be 130W)

the 1060 max 130W

so, provided your psu has a 6/8pin pcie power connector if the gpu needs one, to me your system is fine with 450W

Sweet, my plan is to ditch the 1060 6gb and get a beefier gpu. Whatever it is will run off my 650 watt. The rest will be ran off 450 watt. Using add2psu. 

 

Will use my 500 watt for my media server rig. Appreciate you, just was wanted to verify it before swapping psu around

You're way overestimating how much power you'll need. With just the 650W, you should be able to power the entire system, up to a ~5070 Ti. I'm currently running a 5800X with a 4080 Super on my 650W PSU. The CX650M is entry level, but even still, it can power way more than you think.

With modern PSUs, you can run the full wattage off of the 12v rail.

Powered through a few folding events with my 550w seasonic powering a 120W 2600X, and two 1080's pulling about 200w each, totalling about 500w of just CPU/GPU, and then whatever the various other components pulled, so it was effectively bouncing off the redline for wattage and never missed a beat.

I appreciate you, was just worried a single 650 wouldn't cut it or it would be so close it would over work the PSU for premature failure.

So you think a 650 would run my system and pretty much any graphics card? What GPU would it not run?

As long as it's a quality unit: the total system power being near capacity should not affect the ability to provide said power for extended periods. Colling may be a concern if in a restrictive case, and it may not be in its peak efficiency curve (usually around 50-70% of rated output, but a good quality unit like a modern Corsair CX000M (2021 and later) or Seasonic Focus GX/GM or SuperFlower Leadex should be totally fine to run near peak, and the 10yr warranty is there for if it fails before that time. 

A quality 650w should be able to handle a 150W CPU, 300w GPU and various other peripheral components without even blinking.

Case is massive with plenty of breathing room. 

 

Since I have them I may as well keep them at peak operating. Not every day you can run 2 psu anyways lol. I feel good about running the whole rig off of 450 watts without my GPU. With GPU, I'll prolly just have it ready to go for my separate one. I appreciate ya.
