Hi my power supply i just bought ( Corsair CX 750W Fully Wired 80+ Bronze Power Supply) is making a grinding,Buzzing sound when i launch a game and my Gpu temp goes higher and higher, my specs. Asus Strix R9 390X Gaming 8GB GDDR5 DVI HDMI 3x DisplayPort PCI-E Graphics Card - Intel Core i5 4690K Devils Canyon Quad Core CPU Processor 3.9GHz 6MB Cache S1150 - Asus Z97-PRO GAMER S1150 Intel Z97 DDR3 ATX Motherboard LGA1150vvvvvv - Corsair Dominator Platinum 32GB 4 x 8GB 2133MHz DDR3 C8 RAM (CMD32GX3M4A2133C9) - NZXT KRAKEN X41 AMD & INTEL WATER COOLER VARIABLE SPEED 28CM RADIATOR. they are all new and im just wondering wtf is going on did i buy the wrong power supply ?

Yes, you bought the wrong PSU. Those CX units are not very good, and the 750w, IIRC, is the worst one of the bunch. Get your money back and get a better one.

hi thanks for that i was looking at this is it any good? http://www.ebuyer.com/655998-evga-supernova-850w-semi-modular-80-bronze-power-supply-110-b2-0850-v3 budget isnt an issue

logainofhades · Feb 26, 2016

Yea, the B2 850 is a decent PSU as well. Evga B2/G2/GS/P2 are all well made units.

MrDarkPsycho · Feb 26, 2016

which would you say would be best for my build as this is my first build

MrDarkPsycho · Feb 26, 2016

and im looking for one that has everything attached so not to buy extra wires

logainofhades · Feb 26, 2016

A G2 unit would be my choice. 10yr warranty, and some of the best PSU's you can buy. P2's are good, but platinum rating isn't necessary. GS units aren't bad either, but they have shorter warranties, as do the B2.

im looking at http://www.ebuyer.com/630113-evga-supernova-850w-fully-modular-80-gold-power-supply-220-g2-0850-xr but it doesnt come with any wires so im wondering where i get them adn what they are called if you could help me it would be much appreciated

logainofhades · Feb 26, 2016

Why wouldn't it have any wires? Any brand new PSU would have the needed wires. It is a fully modular power supply.

MrDarkPsycho · Feb 26, 2016

ah thanks its just in the picture i couldnt see any wires

so if i buy http://www.ebuyer.com/630113-evga-supernova-850w-fully-modular-80-gold-power-supply-220-g2-0850-xr i wont have that noise and my gpu wont overheat like it did with the wrong pcu ?

logainofhades · Feb 26, 2016

You won't have a noisy PSU anymore. You overheating problems I doubt are PSU related. Verify that nothing is getting in the way of your fans, on the graphics card, and they are spinning properly.
