Hi,
i am specking out a new build after 10 years, with the new build total currently at 3.5k i am looking to save money where i can. sadly the GPU is eating all my budget ( :mad: Nvidia). i curently have a 850W Seasonic PSU in my system, at the time i bought (2018) it it was overkill but only £100 then.
my new build on PC partpicker adds up to 635 watts total with a 4080. Can i use my old 850 PSU when everything is on full load? would this be a safe thing to do or should i buy a new 1000W PSU? using my existing PSU would save me £300.

Thanks

Paul

You'll be fine, power spiking not too bad on 4080.
 
It's a solid PSU with a ten year warranty and lots of built in circuit protection... that's why you buy a good PSU in the first place... it costs a bit more but it's good for 10yrs+

?

Cheaper drives that are just as good as the 990 Pro. Look at WD's X models. https://www.overclockers.co.uk/wd-b...rive-with-heatsink-wds200t2xhe-hd-594-wd.html

Also do you really need such an expensive AIO? You pay an awful lot more just for a screen with no added performance.

In that case, there shouldn't be any living drives in my house :D
They fill them with inert gas...

/back to topic. If they lose power abruptly its double bad, system may corrupt / hardware may damage, if you are just nvme/ssd its just its single bad.

I'm not saying it is a good idea to keep doing it (and I know it was a big issue with early SSDs), but I'm pretty sure they test them for this nowadays and the drives are not supposed to just brick themselves anymore. Samsung talk a little about it here.
