Corsair CX850

[RollTime]

There's a CX850 for $40 on Reddit, not the M version, seller says it was used for mining. Worth it? Is it likely to fail?

Only the CX850M exists and it's the old green version. Probably a scam.

 

The CX750M (new black version) does exist though

Strange. Thanks.

Worth it? Do you need a 850 watts power supply?

 

I personally am fine going cheap for office builds or generally low end stuff but when we're talking about 850w this is usually SLI set up or a overclocked HEDT platform and such, builds where cheapening on PSU makes absolutely no sense.

 

Use a 850w power supply on a build that will eat 200~300w maximum load also is a waste.

It's cheaper than the 650 watt PSU I had planned to buy. I mean it is worth it to get used?

If you do need a 850W power supply, get a RM850i or RM850x. They're good power supplies.

 

You could also get any Tier 1 power supply from here:

Probably not, PSU is not something you want to be doing every thing possible to cheap up a few dollars off it, say you install this on your system and it goes POP and kills your motherboard and GPU alongside it and you'll be looking at a terrible loss with no one to complain to.

 

More watts than you need are completely useless, it'll just make your power bill more expensive without need.

Since he needs 650 watts, I'd go for a RM650i or RM650x. I wouldn't go for the CXM series because sleeve-bearing fan, and the RM series is higher quality anyway.

I had a SeaSonic 620 EVO edition planned, pretty sure it's tier 2 or 3. Is that good? I wasn't sure.

If you need 650W, you can afford a high end PSU. If you can't afford a high end PSU, you won't need 650W. What are you powering?

It's an ancient, overpriced piece of crap.

8700k and 1080, most likely overclocked.

What you should want is a good 450-550W PSU. Whisper M, Straight Power 11, RMx 2018 or RMx. That'll be plenty for overclocking, and they are all significantly quieter than the CXM.

There's a new "black version" of the CX850M as well.

 

There is no CX850 non-M.

 

You have to be careful with used PSUs.  Especially from miners that tend to buy the cheapest products from questionable sources.  There's been A LOT of counterfeit PSUs, especially out of China.  What they do is take a lower wattage PSU and then create a new label for it.  I've seen RM850x's labeled as HX1000's, CX550M's labeled as CX750M's.....
