Cheap 650w PSU

Recommended Posts

Posted · Original PosterOP

I found some nice ones, but they are now out of stock.

So is there an ATX 650w PSU around £50?

do you need 650w? because wattage and efficiency  have nothing to do with quality. 

a 550w is more than enough for any single gpu system. 

what are you powering?

If you're looking to get a 650W PSU at 50 quid, then you probably don't need 650W in the first place.

What components are you using?


Desktop: Intel Core i9-9900K | be quiet! Dark Rock Pro 4 | ASUS Strix Z390-F | Corsair Vengeance LPX 2x16GB 3000MHz CL15 | EVGA GeForce RTX 2070 SUPER XC Ultra | Corsair RM650x | Fractal Design Define R6

Peripherals: Ducky Shine 7 (Cherry MX Brown) | Logitech MX Master 3 & Razer Basilisk X HyperSpeed | Beyerdynamic Custom One Pro Plus | Audio-Technica AT2020USB+

TLDR: You're probably better off with a competitively-priced 500W unit than a cheap 650W unit that starts putting out shoddy power after 300W and might literally blow up.  

As an FYI, most systems won't use that much.

my system for example:
3900x - 130ishW under load at stock - though I usually run undervolted or in 65W mode
64GB RAM - 10W
RTX 2080 - 250W
3 SSDs - 20W

motherboard - 15W

cooling - 10W


That's under 450W. In all likelihood 99% of it's life it's under 400W and 90% it's under 350W. It's really hard to simultaneously max everything out if you aren't running power virus apps (e.g. prime 95, furmark) - seriously... I started playing games again... a lot of the time my CPU load in windows is at 5-10% (and I placed the CPU in 65W mode and set a 100FPS cap via Freesync), I'm probably drawing around 10-15W from the CPU tops and maybe 200W from the videocard. MAYBE... However much DOOM takes.

Speccing systems is about understanding what you need. What you're doing is similar to getting a used dump truck (that's barely works and is likely to break down) to make grocery runs because it has a higher hauling capacity than an Volkswagen or Toyota car. 

Understand your use case. Get something that meets your criteria for doing an AWESOME job at the use case. You don't get extra credit for having a higher number on a label.

As said above a 550w is enough for any single GPU system and hdds/ssds and peripherals don't use that much power either way.

How about you tell us what components you are using and we can suggest a PSU?

What is that? A ryzen 9? So a 12/16 core?

No gpu? If so you won't be able to boot. 

Not very detailed. But if you're going for a 12 core/16 core and you're cutting corners like the PSU for example. Then you probably don't need a 12/16 core. 

What are you powering? I'm sorry but this days nothing.

still, what cpu? 

a system power 9 500w/ cx550 should be good enough, for 40 pounds, there aren't many decent units in all honesty, if you're not going to build it now i would say wait and save up more for a unit.

5-10W each. 7*3 = 20w. To be fair that's on the low side given one drive is Optane... Maybe slap on 2W extra. SSDs might pull 5W if you go for the highest performance units. 

 

https://www.anandtech.com/show/8747/samsung-ssd-850-evo-review/10

 

I only use hard drives in NASes... Which I keep in a different room. They're around 7W each... 10W if I went inefficient. 

 

I guess a mouse and keyboard might use 5W.

Everything past CPU and GPU is pretty minimal. 

 

And you probably don't need a 650W PSU.

R9 390

R9 390 is < 300W. 

 

If you're trying to cut corners on a PSU, just get more energy efficient other stuff. 

 

130W would be an upper bound for something like a 3900x, 90W for a 3700. 

 

Other stuff might be 50W. 

 

You might want a 550W unit for some overhead but yeah.
