Question Which PSU to keep

[wyliec2]

I'm trying to decide which of the two PSUs I already own I should use...

I'm building a new 'daily driver' PC for general home office use - no heavy/specialized use (no gaming, no Handbrake encodes, etc.).

Most likely an i5-13600k with a lower-mid tier Z790 board and an existing 1050 Ti. Maximum expected power needs at 500 watts.

From previous builds, I have two Seasonic PSUs - a Focus GX-650 80+ Gold and a Prime PX-850 80+ Platinum. Both of these are 3 years old (so plenty of life left) with 10-year and 12-year warranties respectively. Both have been very lightly used and are in like-new condition.

My gut tells me the 650 watt unit would be the most efficient choice. The 850 which is very much overkill for my purpose and I doubt the higher efficiency (gold vs platinum) offsets this??

Thanks in advance for any thoughts from the community!!

Offhand, I tend to agree with you on the 650.

However, my crystal ball says major problems with Z490 and 13600K.

Thanks for pointing out the typo....Z790 (not Z490!!)

I'm definitely going with the 650 watt PSU now - I wound up getting the 13500 as BestBuy had them on sale for $210...this is less than Microcenter's price for the 13400....and much less than the 13600K.
