New Power Supply - Help!

[ethan.redstone]

Hello everyone,

I am looking to upgrade my PSU, and I am wondering which one to get.

I am looking for support for at least 4-6 HDD's & 2 SSD's - along with support for 2 Graphics Cards!

I prefer modular, just so it looks more aesthetic!, however i'm perfectly fine going with a non-modular as long as it works & is 80+ rated!

Also, please link cables that I might need (to support the hard drives) when linking a power supply if possible!

I'm not looking to spend a lot of money, so nothing too ridiculous please.

Lastly, Currently my specs are:

- i7-4790
- GTX 980

However I would look to upgrade to:

- i7-8700k (with high overclock)
- GTX 1080 & GTX 980 (or something similar) - NOT for SLI, but for dual rendering / monitors
- 32GB DDR4

T.I.A

Well, I know what I would be buying over here in Germany and would surely not go for the cheapest solution, but invest 10-20 bugs more into a long lasting PSU.

For what you describe above please have a look into the following link: https://www.newegg.com/global/uk/Product/ProductList.aspx?Submit=ENE&IsNodeId=1&N=100196081 600479295

With the ambition do fire 2 GPUs I would suggest to go for 600+W offering 2x6+2 PCI-E connectors.

Modular or not does in your case not make a big difference, because even with a modular one you would be connecting/using most of the cables.
Therefore go for a non-modular brand PSU like Seasonic also offering a longer warrenty period.

If your going to run 2 of those cards, (a bad Idea if gaming) with a high overclock on the CPU then your need a good quality 850 Watt power supply.
If your going to stick to 1 card with a high overclock then a quality 650 watt would do fine.

Not sure where you live but I would recommend one of these for the 850 Watts and if your going to stick to one card buy the 650 watt version.

For single GPU systems a good 450W 80+ PSU should be sufficient, no need for 650W unless you show me that this is needed Zerk 😉

424 watts with no overclock. Probably can add 20 more watts for a decent water cooler since their going for a high overclock and about 50 more watts for the overclock depending on how much voltage increase is needed.

This is fairly colse before he even overclocks. 450 Watts will not work,
If you have no clue don't answer.

Please read through this before you state something like the above without any reliable reference. 😉 So around 400W under full load making a good 450W PSU sufficient.

Those numbers looke skewed.
Asus GTX 1080 224 watts.

I7 8700K 95 watts before overclocking.
About 60 watts for the rest. More if you add a water cooler. Then the 4 hard drives.

That totals 84% of a 450 watt PSU before overclocking the processor. Not a good % to run a power supply.

I also do not support driving a PSU to its limits. Usually if you go for a good 80+ gold PSU there is still some buffer. I am not a fan over overzizing PSUs as I have seem too many childish rigs with 1kW PSUs only consuming 400-500W.
So let's agree on a compromise Zerk: good 500W might be good enough. What brand would you prefer or recommend to the TE? I would go for Seasonic, Super Flower...
