An enquiry about my build.

[vedu_uttu]

Hi y'all,
My pc build has become about 9 years old now, so I was thinking about refurbishing it. Now, the specs are too old(ish), but the parts I am going to replace are:-
1)Processor-Going to add a new pentium G4560
2)Motherboard:-A B250 Chipset MOBO
3)Memory:- 1x DDR4 RAM clocked at 2400mhz
4)HDD:-500GB SATA 7.2K RPM

Absolutely not a big list. I am going to replace only a few parts as I am out of budget now and I already have a predator gaming laptop lying over. Everything else in the build is safe and sound(Disk drive[DVD combo], PSU[450W], Video card[Low profile GT 610],etc)
My questions are:-
1)If this build is compatible?
2)I already have a PSU of 450W.. Should I use the old one or purchase a new one?
Apologies for any mistakes.

Edit:- PSU has been replaced one time and the new one is only 1 & 1/2 years old

Components are compatible.

Though, what's your PSU's make and model (or part number)? Since what matters with PSU's is their build quality and not as much their age.
When knowing which PSU you have, i can look up it's build quality and also tell if you should replace it or not.

Oh my, there's almost no info about this unit on the official page,
specs: https://zebronics.com/products/economy-series/zeb-n450w-dsata

If the official page is that empty then i wouldn't hope for any decent build quality from that unit. Also, couldn't find any reviews either to state how good or bad that unit is. Due to the lack of info about it, it's best assumed that the PSU is a bad unit.
Keep in mind that PSU is the most important component inside the PC since it powers everything. And when low quality unit dies, it has the power to fry ALL it's connected to.

I suggest you replace your suspicious PSU with good quality PSU. Anything from Seasonic lineup will do just fine, e.g M12II-520 EVO,

amazon.in: https://www.amazon.in/Seasonic-Modular-Supply-Certification-SS-520GM2/dp/B00HG2R3FU

All my 3 PCs: Skylake, Haswell and AMD are also powered by Seasonic. Full specs with pics in my sig.

Thanks. I looked it up on Amazon and ordered it. Never heard of the brand actually but as you suggested it, I have bought it.
Thanks for your precious time and co-operation again.
