My PSU is very loud. Even at idle.

[Aw_Ginger_Snapz]

So I recently built a new PC for myself. It has a AMD R7 1700 at stock speeds (most of the time), a Gigabyte GTX 1070, an SSD and HDD, and a Asus B350 Prime Motherboard, all of which are inside the NZXT S340 case. To power these components, I have a EVGA NEX 750B power supply that I picked up new at Microcenter. When I first powered the PC, the I instantly noticed a squeaking sound coming from the machine. After further examination, I realized that the sound is coming from my power supply. I verified that it was the power supply by switching it out with my old EVGA 500w power supply which made no sound. Additionally, the sound doesn't sound to be coil whine, and the sound becomes louder as my system goes under load. Does anyone have any ideas as to what is causing the squeaking sounds, and any ideas on how to remedy this problem? Has anyone had a similar problem to this?

Is it a loud fan? If so, you can replace it.

Sure it's not coil whine? Maybe a dodgy fan... You could get a another fan, or RMA the whole unit.

If your old EVGA is fine, why not use that one?

You'd just open it up and replace it. Be careful though. Or you could just replace the entire thing.

I have to use my old EVGA PSU for another system. I can't RMA the unit because I sent in the S/N for rebates. Therefore, EVGA will not take the PSU in for RMA. Unfortunately, I bought the PSU a month before Ryzen came out, and sent the barcode in for rebates as soon as I had my hands on it. So unfortunately, RMA is out of the question.

I know, but what fan would I need? Is it a 2 pin, 3pin, or 4 pin fan? Is the fan wired differently than a normal header? would it require soldering?

Maybe a nice Noctua fan?

Google much?  There's loads of detailed guides online. 

I'd make sure it really is the fan before doing anything though, either by unplugging it, or just jamming the fan so it won't spin.

Depends on the power supply. Probably no soldering needed, if the fan speed is variable it's most likely a 3 pin but just check to make sure.

Has anybody had any issues with an EVGA PSU? I've owned at least 3. The first one was a 600w and was a pile of garbage, the second one was a 500w and works awesome, and now my third one is a 750w and is loud. The only reason I keep buying from EVGA is because they provide solid features for what you pay. I would have bought a 750w 80+ Bronze Semi-modular PSU from corsair, but that would have cost at least $100 at the time. But I stuck to EVGA because I got those exact specs for about $60 at Microcenter. I will probably never buy from EVGA again after this...  Any suggestions of good brands for the future?

Each company has lemons and crappier production lines, could have a lemon or went with a lower Tier level then your 500w.

The modified Yateloon D14BH-12 that's in this FSP build NEX750B / B1 isn't the quietest of power supplies. It was also used in their NEX-G / G1 series, in which the 750w model has shown to spun up to nearly 1000RPM at low loads and this is with a Gold efficiency power supply that will generate less heat than your B1 unit.

 

Most companies sell products at a wide range of quality with different pros/cons. It's up to the buyer to research on the product they are purchasing to make an informed decision on what to buy. If you don't, well, you can end up being upset with any particular company - causing you to think you probably never buy from them again.

 

EVGA have good to excellent options, but they also have some rather mediocre / poor options as well. The NEX750B is among the latter, which is understandable if it had been priced at $60 USD for a 750w unit.
