Do I Need A New PSU?

I was having problems with my PC last week and initially thought it was my motherboard but the PSU blew. Luckily I had a spare one which I've used to get me up and running again. The PSU that's blown is the EVGA Supernova G2 850W 80+ Gold which I can RMA.

The one I'm currently using is the EVGA 650W GQ 80+ Gold. Would this be fine to run the following:

Ryzen 3600
MSI Tomahawk Max
Team Group 8 Pack 3200
Corsair MP510 M.2 SSD
Samsung 850 500GB SSD
GTX 1080Ti
Corsair 115i Pro Cooler
5 x 120mm fans
Logitech G513 Keyboard
Logitech G502 Mouse

I always like to have some overhead so I tend to buy more expensive PSUs than I probably should, not overclocking anything at the moment either. I've been looking at the Seasonic Titanium ones but should I just stick with this 650W one?

Good 650W PSU is enough for that.

You can try using https://outervision.com/power-supply-calculator and see what it comes out with as the power requirement.

i RMA'd the PSU and received the replacement yesterday. Rather naively I assumed I'd be getting a new replacement but they have sent me an 850W G3 PSU that is a refurb. It looks new apart from coming in a simple box and the serial number stickers look like they've been scratched through deliberately.

Not sure if I want to use a refurb PSU but the 650W I'm currently using has been fine so I'll be sticking with this for the time being.

Don't accept the refurb that's BS. Get on to them and demand a new PSU.

Legally speaking they don't have to offer a brand new replacement, But it must be a suitable and comparable replacement.

The legal reason being, if you've used a product, lets say, for 2 years, than you have had some value from it. so legally speaking ... blah blah..

A reputable company would give you an upgrade or a brand new like-for-like equivalent, but if the serials are missing... where did you rma it to direct to factory? refurbish are not often as bad as they seem, as presumably they've been tested to some extent.

How long have you owned it for?

I would not accpet that replacement sounds dodgy as **** to me. I shan't be buying an EVGA PSU either given that's the level of service they give, someone's already failed PSU... :rolleyes:

Just not good enough, he bought a PSU with X years gaurantee on it, it failed within that period, therefore he's due a brand new replacement.

Unfortunately it's in their T&C's for RMA's. If it's within 30 days you'll get a new one but after that it's a re-certified one. This from their forums:

"With RMAs, we will send out recertified units (units that have come to our facility, and passed our extensive internal testing) as replacements. In the event that the product you sent to us has failed within the first 30 days of purchase, we will send out a brand new unit if we have stock available to do so. Please also note that ALL of our products that are sent out for RMAs are packaged / sealed, and in an unopened condition"

The one that blew was 6 years old and they have sent me an 850W G3 PSU which is an upgrade from the one I RMA'd. The PSU itself looks brand new and I can't see any marks on it at all. It just came back in a generic EVGA box with a bag full of cables with the PSU wrapped in bubblewrap.

The serials weren't missing, just that the labels have been scored through. Think this is done to show that it's an RMA in case it gets RMA'd itself in the future - if that makes sense!

I don't need it now though and I'm reluctant to rebuild my PC just to see it it works. Might just keep it as a backup, still got 4 years warranty left.

Being 6 years old, it could be old enough to fall under the sale of goods act, or the newer consumer rights act. Both are quite similar though in this respect, although these apply to your contract of sale with the retailer you purchased it from, not the manufacturer.

A 10 year warranty offered by a manufacturer, for example, rather than the retailer, is above and beyond your basic legal consumer rights. After 6 years use, there's no right to a full refund or a brand new like for like replacement. You could in theory take the retailer to court, but you'd have to prove the item should reasonably last longer (maybe not too hard, PSUs often last longer than 6 years), and had a fault/defect (more difficult). But after 6 years use, *if* you won, the court might only award you say half its value or less as you've already had 6 years value out of it. SO on a £100 PSU, you might end up with £40 or £50, for all that effort. All of a sudden a refurb better model doesn't look to unappealing presumably the'd have to load test it as part of the re-certification process so I wouldn't be overly concerned about using it.
