Box computer planning

Hi All,

Tomorrow I am purchasing a CM elite 110 mesh and I would like some help with what I can do with it.

The components being cooled are Zotac GTX 1080Ti Mini and Ryzen 7 1700, and the PSU is a EVGA supernova 750w p2 which will eventually be getting custom length cables to help.

First are mods, I am thinking of painting it with the NES grey colours, I love that theme and painting it should be simple.

Next is cooling, I am looking at either a AIO or L9x65 AM4 but not sure which although an AIO looks like when everything is together may not help as it will be really close to my PSU and everything will be rather tight in there, if I get the air cooler a 140mm fan will be put in the front of the case to help cool everything.

Finally is mounting the PSU, I noticed cooler master in their pictures mount it up side down, but would using the PSU as an exhaust help?

 

Any thoughts?

 

Many Thanks

Painting is not simple. It is somewhat difficult to get a clean, blemish free result without a decent paint booth.

 

The case is designed to have the psu pull air in from the top and exhaust it out the rear. Effectively isolating the psu cooling from other components. If the psu was inverted it might compete with the cpu cooler for air. (Check psu documentation, some are not designed for inverted operation.)

 

A 750W psu is silly. There is no need for such a high capacity unit. It is literally not possible to stuff enough components into the case to even press that size psu. A 550W / 650W unit is more than enough. Consider a Seasonic Focus Plus Gold / Platinum model. They are only 140mm long. Another option would be an sfx Corsair SF600 with adapter plate.

Funny enough I have a SF600 + Adapter also but it makes a lot of noise coming directly from the power connector on the 1080Ti, so we swapped the SF600 for the 750w in another build we have, been fine since, not sure if its the cabling but reads fine on a PSU tester.

Odd about the psu. Were the connections at either end tight? I guess there is no way to try different PCIe 6+2 cables, to see if the sound is a harmonic from a loose pin connector.

Connectors where fine and unfortunately no as I don't have another cable set, got worse as we put more load through the card but stopped on the 750w.

Can you test the SF-600 with a different gpu? If the noise is really the fault of the psu, you might be able to get a warranty replacement.
