Buying used PSU

Hello, recently I sold my Corsair CS650M power supply. I sold it, because I got a deal on two Vega 64 cards. Now I'm looking for a new PSU that can handle both cards. 

 

There's an ad for an EVGA 1600 G2 power supply. The seller told me it was used on a miner for less than a year and a half (1 year and 3-4 months to be exact). He told me it was powering 12 gtx 1060s @90w each. It also has 8 and a half years warranty left, but EVGA doesn't transfer warranties. 

 

The reason I'm considering the EVGA one is mostly because of the looks (lol), because I'll be building in a custom 'case' similar to the Thermaltake core p5 and the PSU will be exposed. Also, I've never heard anyone complain about EVGA's power supplies. 

 

So my question is should I buy it, or should I get a brand new CM V1000, which costs about the same as the EVGA one?

I wouldn't recommend buying a used PSU.

Definitely not the G2. A 1600W single rail PSU is just a bad idea to begin with. 

The exact same thing would have happened if they used a G2, as it's also a 1600W single rail PSU.

Look for another ~850-1000W PSU that supports multi rail instead.

A used one is a used one, and no warranty should reflect on the price. But the 1000W CM is more than enough and 1600W is more than twice the power you'll ever need.

Not too familiar with the Bulgarian market.  Though I do have a number of Bulgarian Matchbox cars.

 

Is there a particular e-tailer you use there for computer components?

I've bought a couple of used PSUs before, mainly for very cheap builds where it's not worth buying a new one. They both worked for more than a year and I got rid of them as they both developed coil whine.

Buying a PSU, especially one that's been used for mining, isn't an amazing idea. I would definitely go for a new one.

@jonnyGURU @mrplt Sorry for the late reply, I've been quite busy lately...

I decided to pass on that used PSU and spend a bit more on Thermaltake Toughpower Grand Riing 1200w as it seems to be quiet high on the PSU tier list. By the way, thank you for keeping the list up to date @LienusLateTips and everyone who contributed to it!

Thanks to everyone who took the time to reply to this thread and helped me with the decision! 

 

Edit: Oops, it was the toughpower iRGB that's high on the list. I guess I'll go with Be quiet Straight power 11 or Cooler Master V1000 l then.

Brand new one because you lose all or most of the warranty with most PSU.


Also the higher wattage EVGA units are really really loud. SO if you get a decently quiet VEGA64, the PSU will be far louder.

 

As for the two PSU; I'd get the straight power because multi rail, thus a bit safer if a MOSFET burns.

Cooler Master V1000 Platinum would be decent as well, though sadly only 2 Rails.
