Hi everyone.

I've been um'ing and er'ing about upgrading my PSU as I'm trying to get the most time out of it without risking my PC (i'm not sure how common PSU faults lead to other parts being damaged).

My current PSU is 8 1/2 years old with a 10 year guarantee. OCZ 850W Gold rated, but sadly OCZ are now under so my guarantee is now worthless. I'm assuming my 10 year guarantee means my PSU will last at least for another 6-12 months but I might be optimistic.

Twice over the last 3 months my PC has refused to turn on after sitting off overnight. I've 'fixed' the issue by unplugging everything at the back, turning the PSU off, opening up the case and re-pushing in the mobo power connector. By the time I plug everything back in, it turns on fine as if nothing had happened.

Simply turning off the PSU for a minute off and on again didn't fix it. Assuming I've seated the mobo power connector properly, is this a sign my PSU is on its way out or something else?

Thanks for your time!
 
It's had it. Unless you want to keep reconnecting the 24pin ATX power connector to your board each time you want to turn your PC on & that isnt going to do either much good, both connectors are not designed for that. OCZ were OK at the time & were popular but they did make one or two models whose quality & reliablity were 'questionable'.

10 year warranty? As you said that expired when OCZ went out of business back in 2014. Proof:

Having said that 8 1/2 years is a good innings.

10 Year warranty from a company that should be around for another 10 years. UK based RMA too.

Thanks for advice Grimley. Is 650 enough for futureproofing do you think for those 10 years? Say if I get a 3080/6800xt + 5800x in the future? I feel like it should be fine, but I feel like you know what you're talking about so perhaps you could advise whether 750 would be a better choice or just overkill?

OCZ was always mediocre with only couple better models.

For example ZX uses capacitors chosen for cheap enough price.

And while Z850 had good capacitors that design with extremely big heatsinks and wire spaghetti made sure they didn't get airflow.
