did I make a mistake on my psu decision.

[emj503]

So i'm doing some major upgrades on my machine
old specs:
amd athlon 750k yada yada
asrock a85x extreme 4-m
corsair cx 430w psu
asus 7790 2gb
gskill 2133 sniper series ram
who cares about the case

anyways here's the first upgrade I made(yes huge upgrade I know ^^)
i7 5790k
asus sabertooth z97 mark 2
corsair cx 430w psu
asus 7790 2gb
gskill 2133 sniper series ram 2x4
who cares about the case

new specs tomorrow:
i7 5790k
asus sabertooth z97 mark 2
corsair cx 750w modular psu
msi gtx 970
gskill 2133 sniper series ram 2x4
who cares about the case


anyways last night I made an impulse purchase and ordered a msi gtx 970 with a corsair 750 cx modular psu. I went with the lower end psu because my old one has served me fine for nearly 3 years now no issues so I decided i'd cheap out and just get that. now this morning I wake up and read everywhere on the internet about coil whine with higher end gpus and this particular power supply. I know coil whine can happen to any PSU but it seems to be a prominent issue with the cx builder series power supplys.

Now my question for you the tomshardware community should I,

A. refuse shipping when UPS delivers to my house tomorrow for the power supply wait for a refund and get a quality power supply or should I
B. stop reading reviews on the internet and giving my self anxiety and test it out and ruin the chance of getting a refund I dont even want to deal with RMA's because it'll just be the same recurring issue.? and if it gives me problems just order a quality psu later on? money really isn't the issue here I just don't want a useless powersupply laying around uknow?

thanks if you read my long post.

CX series aren't the greatest power supplies , but it's more than capable of powering your new specs.

yea i know this its more then plenty, but I just do not want to deal with this coil whine issue that seems to be widespread on all review sites I've been on with these higher end cards in particular the gtx 970/980. I suppose ill just test it out and If i need to get a new psu it is what it is, ill end up finding some use for this psu if it doesn't work out for me.

That's all you can do , they are second to last in terms of quality in the Corsair lineup.

The cx aren't great PSUs.
But you have a pretty energy efficient system with a 970, and 750w IS plenty.
I've had my tx (discontinued, but good) Corsair 750w for 8 years and still going strong.

Use it, if theres a problem send it back.

Hmmm. That 5 instead of 4 typo had me scratching my head for a moment.
