Thanks for the info. Also if someone else is interested in this PSU, I found a Chinese review (the only one I could find) https://www.expreview.com/66077-2.html

I read some reviews and found out that Gigabyte Aorus P850W has a solid performance overall, almost top class. (No reviews for 750W version tho?) Some gripes are; Non sleeved capacitors hanging at the end of connectors, (I don't have a windowed case, so...) Using double ball bearing fan and weird fan curve causing extra noise, especially at higher loads. (As far as I know ball bearing fans are more failproof than liquid, and since I will barely hit %50 capacity with my system I don't think it will be a problem) Mostly higher price than competitors. (Not in my case) Can't disable semi-passive fan state. (I don't know if it's a problem or not.)

I live in Turkey.

Wow, thanks for clarifying!

Well, I found another option; Gigabyte Aorus P750 (AP750GM) => 115 USD. I realized the 850W version is Tier A- but nothing mentioned about 750W version. (850W version is also available for 130 USD) I know 750W is unnecesary for my build but it also has 10 years warranty, so maybe better buy for the less money than BQ! SP11 550W?

Thanks a lot for checking Spotty.

@Spotty Thanks a lot for the detailed answer! Yes two things with the SF450 is; being 450W and cable lenght. (I read a review that it comes with SFX>ATX adapter, but can't be sure) I'm leaning towards to SP11 550W right now.

Hi all! I couldn't decide if I should open a new thread for this, please tell if I should. Thanks mod! So I have been using my XFX PRO 650W XXX Edition for 8 years now, and just after upgrading my GPU to Sapphire Nitro+ 5700XT (Previously GTX970) I noticed it's making a buzzing noise like coil whine under load. So, I know it's already risky to keep the same PSU on my 3rd system, but after I heard the noise I decided to change it before it blows up or something? I made some research and thanks to you people I found some alternatives in my country to choose from. My system is like below; Ryzen 1600 @ 3700Mhz - Stock Cooler MSI Mortar B450 Mortar Max 2x8GB 2400Mhz Ballistix Ram (Soon to be 2x16 3200Mhz Ballistix) Sapphire RX 5700 XT Nitro+ 1xSSD & 1xHDD (Caviar Blue) Fractal Design Define Mini C 2x140mm BeQuiet! Silent Wings 3 High RPM 1x120mm Fractal Design exhaust fan So, the PSU alternatives that I found are as below. (Where I live, there are not so many options on the 500-600W range with reputable brands, sadly.) Be Quiet PURE POWER 11 BN297 500W ==> 92 USD Cougar GX-S CGR-GS-650 650W ==> 100 USD Corsair SF450 80+ Platinum 450W ==> 110 USD Be Quiet PURE POWER BN299 700W ==> 121 USD Be Quiet Straight Power 11 BN281 550W ==> 125 USD Corsair TX750M CP-9020131-EU 750W ==> 130 USD NZXT E500 NP-1PM-E500A-EU 500W ==> 137 USD FSP Hydro G HG750 750W ==> 143 USD Cooler Master MWE Gold 750 MPY-7501-ACAAG-EU 750W ==> 145 USD Corsair (2018) RM750X CP-9020179-EU 750W ==> 165 USD So what would you suggest for me to pick up on this list. Initially I was set on Straight Power 11 550W but then suprised with SF450 Platinum's price, but can't be sure if I want to go with 450W. Thanks in advance, cheers!
