PSU man-hunt!

[Raytheus]

Good day, everyone

 

I am a complete rookie who has finally saved enough money to build a baller desktop computer (in hopes to future-proof for at least half a decade). 

 

I am using a z790 motherboard, intel i9-13900KS cpu, 2 m.2 SSDs,  32GB teamforce ddr5 ram, msi rtx 4090 suprim x gpu and plan to water cool them both with 3 radiators and multiple fans. For now, I will be connecting the desktop to my TV since this fool is now too broke to buy anything else (yup, I hear you!).

 

Hence, may I humbly request for your guidance as more experience PC-builders, as to what PSU might be the best to aquire for such a build? My initial gut feeling was around 1500 - 1600W with atx 3.0 (which I belive natively supports 12VHPWR for rtx 40 series gpu) but I am unable to find a good psu with those specifications?

 

Please help this foolish amateur to build a needlessly expensive PC by suggesting a good PSU with enough headroom even after accounting for all the components and peripherals, just in case!

Hi quality 1000w PSU should be sufficient. That 4090 is going to run games in a great manner for a long time after people are moving on from the lower end 40 series as its performance is already so far ahead of everything else Nvidea has on the shelf right now.

I think going 1500 1600w is overkill for your needs. however some 1200w are close in price point to the 1000w so that could be an option.

just a quick link with a little info and some pricing for the type you are interested in.

And here is another with 10 year warranty

Yeah, without excessive OC 1000W should be enough.

Another Tier A PSU from PSU cultists tier list - https://www.amazon.com/MONTECH-Titan-High-End-Gaming-Supply/dp/B0BPXQZJV4/ref=sr_1_1?crid=2R9MKY962RBCT&keywords=montech+titan&qid=1680376970&sprefix=montech+titan%2Caps%2C195&sr=8-1

Thank you, so very much, for your guidance, sir/ma'am. May I also ask in-case of overclocking? Moreover, I have read and heard that Thermaltake psu's are not covered by the manufacturer's warranty when our chased through amazon! 

 

I wish to overclock both my cpu and ram (to perhaps over 7000 mhz), with enough knowledge, preparation and prayers!

I have also been recommended the following psu: -

 

msi meg ai1300p 

be quiet dark power 13

 

Not sure how good/useful they are. Sorry for the multiple queries!

I mean you won't really be ocing much anyway that 13900ks is basically running to the limit of what is possible at stock.

That is true! Thank you for reminding me of it.

At max 13900KS would take 250-260W - already almost uncoolable, so cooling would be bigger issue than lacking power.

OC RTX 4090 - 500W max.

Other parts will not exceed 150W

~900W if you are able to cool all the parts at max load.

So I'd still recommend a good 1000-1200W PSU. 

But if you have the money to spend why not more powerful PSU..

Other parts have ~250W of power to use and MoBo, RAM and SSD-s, disks wont exceed it. So I'd still recommend a good 1000-1200W PSU.

I see. Whilst I have a good choice for a 1300W thanks to the brilliant members on this forum. I am planning on liquid-cooling the cpu and gpu.

It is also supremely hard for me to find a 1500 - 1600W, ATX 3.0 compatible psu. Though from what I have learnt, I may not need it. I do, however, wish for some headroom/buffer in case if ever needed.
