Corsair HX750 vs Cooler master silent pro M2

[bichobola]

Hi, i'm going to change my current power supply; currently I have an Antec 550w and I feel that i'm pushing it's limits.

My current setup is:

Asus p8B WS
intel i7 2600k
16GB DDR3
9x 500GB WD RAID Edition
1x DVD-ROM
Nvidia GTX460
Highpoint RocketRaid 2340 (RAID adapter)
3x Nexus 120mm fan

Now I'm between Corsair HX750 (122 euros) vs Cooler master silent pro M2 720 (104 euros).
I need a silent and stable psu.

Thanks for your time.

Your current PSU is not even close to having its limits pushed. That's a 150-160w card and a 95 CPU. Add in 10w per HDD and you're still under 400w.

The question of which Antec PSU does come up, if it's a junk-cap special than replacing it isn't a bad idea.
Between those two PSUs, I'd take the HX750. Given wider options I'd likely pick something else though.

I'm with bob, senseless "upgrade".

Thanks for your help bobnova; i'm open to new recommendations.

The key for the change is that I'm experiencing some very random BSOD during render stages; and to isolate the problem I'm thinking on change the PSU.

What model Antec PSU and what year did you buy it in?

[bichobola]

It's an Antec Neo HE550. I don't know the year.

OK in that case you may think about a new PSU. But not because your actual PSU is not sufficient but rather pretty old...

But if you buy a new PSU, stick with a 550W, that's more than enough for a single GPU and single GPU system. It's a waste of money to buy a 750W in this case...

Thanks all for your help.
