[SOLVED] Is this power supply enough for my system?

[jaime061197]

Hello,

I'm building my own pc for the first time and I'm not sure if the power supply that I've selected is good enough for it. Here is the build:

• Mobo: Gigabyte Z390 AORUS PRO ATX LGA1151 Motherboard
• Video card: Zotac GeForce RTX 2080 Ti 11 GB GAMING AMP Video Card
• Processor: Intel Core i9-9900K 3.6 GHz 8-Core Processor
• Cooler: Noctua NH-D15 CHROMAX.BLACK 82.52 CFM CPU Cooler
• Memory: Corsair Vengeance LPX 32 GB (2 x 16 GB) DDR4-3200 Memory
• SSD: ADATA XPG SX8200 Pro 1 TB M.2-2280 NVME Solid State Drive
• HDD: Western Digital BLACK SERIES 2 TB 3.5" 7200RPM Internal Hard Drive
• Power supply: Corsair TXM Gold 750 W 80+ Gold Certified Semi-modular ATX Power Supply
• Monitor: Acer XV273K Pbmiipphzx 27.0" 3840x2160 144 Hz Monitor

I've seen that power supply in some prebuild pcs with similar specifications and also some good reviews. That, along with the price, is why I've chosen it. What concerns me is that in partPicker I've seen a note regarding the compatibility:

"The Gigabyte Z390 AORUS PRO ATX LGA1151 Motherboard has an additional 4-pin ATX power connector but the Corsair TXM Gold 750 W 80+ Gold Certified Semi-modular ATX Power Supply does not. This connector is used to supply additional 12V current to the motherboard. While the system will likely still run without it, higher current demands such as extreme overclocking or large video card current draws may require it."

I don't intend to do overclock but it is true that I have a large video card, will this be a problem? Do you have any other good option (for a similar price) if this one is not good enough?

Also, although is not the purpose of this question, if you find something else strange in the build, something that I be missing, please tell me.

Thanks!

You're good to go with the PSU you've scoped out, provided you won't overclock! I've refined your list with a PSU with the necessary connectors.

You could go for a DDR4-3600MHz dual channel ram kit, though you should be fine as is. Case? Perhaps we could refine the build some more, reflect a smaller form factor build? What's your budget?

That connector's more for xocers/HEDT users than anyone else. You can safely ignore that warning most of the time.

Ok, so should I get the one I have chosen and buy that one just if I want to overclock or do you think I should pick the Ion+ no matter what?

About the RAM I thought about it but the price increase significantly and I'm already crossing my limit with the budget. That's why I decided to stick with the 3200 LPX.

Also, the case is the one thing I have not chosen yet. As I say I'm trying not to spend too much (too much more I mean), so I will choose something below 100€. I have a list right now of possible options but is too broad yet, I was planning on reducing it and then ask here. Anyway if you have any good option I'm all ears, of course.

As for the smaller form factor, I don't think I will need it, this pc will stay in the same place forever, I'm not planning to move it, and I really don't want to give up space, I want the opportunity update it in the future if I decide it.

Thanks for the help!

To be honest, I'm not familiar with that terminology, I have searched HEDT and what I have found is: "(High-End Desktop) An Intel term for high-performance desktop computers". So then, do you think this build is out of that definition?

Thanks!

You're close with that definition. Generally HEDT refers to builds like workstation ones, with very specific feature sets (for example, quad channel memory).
