Too much for the PSU?

[ljop]

So I recently put together a water cooled build with a thermaltake smart pro 650w psu, after around 15 mins of cpu and cpu high loads a loud fan type noise can be heard. Is this likely to be due to the psu being too weak or other thermal based problems, as hwmonitor suggests the fans are not changing during this.

Specs are:
[email protected] 1.2V
1080ti@ ~1.6ghz+
Msi Gaming pro carbon z270
8x 140mm rgb fans (riing 14) with 3 fan controllers (plug into the mobo fan headers)
2x ssd
1x m.2
1x blu ray drive
1x wlan card
3x USB powered devices
1x cpu block diode
Ek p280 kit

Thanks

Not that I have preferences when it comes to brand. Feel free to explain (maybe I am missing something), but phrases like "Thermalstupid Pro has cheap capacitors", "garbage powersupplies", "penny pinch", etc; seem unwarranted and somewhat childish. The Thermaltake Smart Pro RGB 850W reviewed by johnnyguru got a score of 8.7 which is far from bad. It is not like I picked up some no name PSU from eBay for £20....

With the prices people are willing to pay for that Nvidia sticker it's not anymore rare to see people looking at PSU costing at worst one tenth of graphics card...
Regardless that graphics card will be technically quite obsolete in 3-4 years while good PSU lasts twice the time.

I only paid £670 for my Ti (new + water cooled), so I am not fussed (plus I may move away from Pc gaming by that time).

Sadly it feels like banging my head against a tree and getting nowhere sometimes.

Some people still have the mindset that they have spent too much money on the core components and need to make savings somewhere, see a so called 600w psu for a stupidly low price and buy it without giving a thought to quality and what it can actually deliver. Not saying the OP has done this as I believe he just made a poor choice when it came to the psu yet he could have got something massively better for just a little more money. It just requires people to do some research before buying. Ignore the big label saying 600w/700w etc and have a look at what the psu can actually deliver on the 12v rails and check some reviews, preferably ones that have tested the psu with proper equipment taken it to bits to look at internal component quality. Jonnyguru is probably the best although Techpowerup and some others do a proper job of testing these days.

Think I spent £80, and I was mainly influenced by the 7-year warranty.

To answer your previous questions, the PSU is fan side up (I have 4 140mm exhaust fans), and the GPU is Watercooled. I am interested in the power usage of the GPU as it turns out that while gaming it reaches 2.05Ghz without any changes to the stock voltage (Well the power limit is set at 100%).

Further more, I have changed the cable layout (I had made the mistake of using a split 8pin, now using 2x separate 8 pins) and the increase in volume reduced.

Fan side up means that it is sucking warm air from inside the case through it. If your case has a vent underneath the psu position turn it around so that it's fan facing down. This should make it a bit quieter and it will get cooler air going through it. If the case is sitting on carpet you may need to stick something under it so that the pile doesn't block the psu intake vent.

Turned it over now, may have made a small difference. The PC is on my desk, not the floor. Although to be fair to the PSU, the noise may be pretty modest and it is just my ears + brain being fussy.

Does your case have rubber feet? If it doesn't you could try putting a bit of rubber or stiff foam under each of the feet to get rid of any potential resonance from the case. It may or may not make a bit of difference but is worth trying if you have some rubber or something that you can use.

The case has plastic feeling feet. I have however switched PSUs with someone (although it is another Thermaltake, albeit an 850W gold certified one), coil whine when GPU reaches 2Ghz disappeared, so has the excessive noise.
