Buying a used PSU is a bad idea. What do you want to power? If we know we might recommend something equivalent or better quality up to 70 $.

other than the wattage is way overkill. 

 

as long as it works as it should it should be fine.

Since when does CM offer a transferrable warranty? They don't. You won't get any warranty. 

What are you powering?

No, because:

2. Who Is Protected

The original customer purchasing the Cooler Master Product is covered under the Cooler Master Warranty Program.

 

 

So you can kiss the Warranty goodbye as you won't get it as you are not the Original Customer purchasing it.

And it beeing a Seasonic X/P Series based unit, it might cause Problems.

 

Besides that:
IF you have the need for 1000W, you have the money.

If you don't have it you don't need it.

Simple as that.

 

So what are your components, what you're using it for?

I think there are some tier 1/2  450W psus around that price.

there are some tier A PSUs with that wattage. and they are around that price, but that is purely on a country to country basis. 

 

if he can get a Tier A PSU at that price id get that instead. but for it not being the US, 70$ for that PSU aint half bad of a deal.

Agreed, but i am concerned about what Stefan said above about the warranty. And why someone wants to sell that unit in the first place? Might be coil whine or something more important than that?

...even if the PSU does not work with his setup??

Or dies within a year or two?

 

The real Problem is that it doesn't have no Warranty and no way to return it if it whines or something like th at...

 

PS: I really need to get my P660 in my VEGA System...

[M0SIE]

If so can you guys recommend me a psu i need a psu over 650w and fully modular thx

that is the only concern when buying PSUs used. 

 

PSUs are just about the last thing people sell from their systems, and there is often a reason behind selling it. especially when its a high wattage, high quality unit.

PSUs can be rather expencive in other countries, so the price isnt half bad. 

the issue is "why is he selling it?". The PSU itself has good enough quality to the point it should survive, but it can be a DOA unit that the buyer noticed late.

warranty can be a pain. esepcially with the varying degree of consumer protections in different countries

So you're running a 7900X and an RTX Titan in a SFF system? I mean, since you need 650W, you must have that kind of power hungry components. 

 

Or what are you actually powering?

How would they know who bought it if there's no name on the receipt? The warranty follows the part, not the buyer, it has to be so legally.

The seller was selling as he upgraded to a more powerful psu the warranty is from a retailer who just needs a recipt for the warranty(he will provide the recipt

this list. grab a tier B or above PSU. also you most likely wont need more than 550 watts

They might keep records of who bought it especially if it had been bought via credit card.

Hmm i think your right thx

The product must have a warranty, not the "owner".

Yes but the beneficiary of the warranty is the owner of the product.

If it’s a deal I’d do it. Have many times and will continue to do so. 

 

Half of my psu’s are used.

Same. All of mine are used except for my SFX 600W corsair psu (because I couldn't find a used SFX psu on the market lol)

 

• 3 Antec Truepower 750w PSU's. 2 have been running in computers for 5 years now. 1 is in my 1800x streaming computer. Gutless little buggers and glad no one picks them up because of the terrible wire braiding that makes it look cheap.
• 1 Seasonic M12II Bronze 620W modular. Sits in my wifes computer.
• 1 VS600 Corsair PSU. Not proud of it but it is powering my parents old Xeon W3670 build. Was $15 so can't complain, but is the worst quality PSU I can see from the bunch. It also feels lighter than a feather and lacks any form of quality. . Had to replace an old Antec Earthwatts that died because the fan stopped working after it got clogged with dust and hair.
• 1 700W Silverstone Olympia....running in my  i7-950 computer from 2009 that i gave to my grandpa....it was a shitty quality psu back then yet somehow it is still alive. Just like the VS600 cheap shitty chinese caps that will go at any moment. 

PSUs have not changed a hell of a lot in the last 10 years. They still use the same safety mechanisms. Efficiency has changed only because 80 plus platinum did not exist but that is it. People still running old Corsair AX750's and AX850's that are top notch for almost a decade. 

 

Most people are pretty honest but if you are paranoid that it is a blown psu, usually it isn't hard to shine a light and look for burn marks or just get a paperclip, jump the  green and black wires on the clip side and see if the psu fan turns on

Please verify that you need that kind of wattage. I doubt it. What are you running? I hardly believe you'd need greater than 550w wattage.

 

In that case, I'd get Bitfenix Whisper M 550 or SeaSonic Focus Plus Gold 550. They both reasonably priced and modular. Roughly 100USD.

Could you share your pc components? I bet that 550w would be enough

hmm sorta related so ill just post here because i dont want to start a new thread about it.

 

im looking at a kijiji listing for a EVGA 650W GQ 80+ gold for 70cad (~50usd), which is the same price as a new 550w 80+ bronze coolermaster masterwatt i've been looking at. I only really need a 550w psu, but the coolermaster one and the cx 550m are both on backorder and idk when theyll be back in stock which is why im thinking about going for this one.

 

The guy's had it for a year and said he's getting rid of his entire system. And frankly, ive never had an issue with buying used stuff as long as it's been in person, so im not too worried about quality/state of the item. Also, ive been browsing through the evga forums and it looks like they offer second hand warranty, so there's that too. It's about 100w more than i need, but 80+ gold is nice, its B tier instead of lower and its basically what i wouldve paid for a 550w 80+ bronze psu that i would need to wait at least 2-3 weeks for anyways, so i think im gonna go for it.

I agree that buying a working PSU from a working PC from someone "in person" is relatively "safe".  

 

Just keep in mind that, as Stefan Payne pointed out above, warranties aren't transferable.  If you think you're ok without a warranty, go for it.

 

The reason why open box isn't good is because the PSUs aren't tested.  They're just returns where the customer didn't report back that the PSU exploded, died, caught fire, etc.  What you get is a crap shoot.  I used to work for a place that would buy lots of customer returns from big box stores at discounted rates (typically sold at auction).  It was my job to go through the stuff and figure out what could be re-sold or fixed and re-sold for a reasonable cost.  We ended up only being able to sell about half that stuff.

 

The problem with refurb stuff is that it's tested, but not as thoroughly as a new product.   A new PSU is "burned in" in a chamber for 1 to 2 hours before shipping out of the factory.  A refurb may be load tested, but only at room temperature.   This is why stories like this one are so true to my heart:
