Is a Corsair CX 600w sufficient for a GTX 970

[Darel Pates]

I have an HP Pavilion HPE h8-1360t with an i7 3770 at 3.4 ghz and 10GB DDR3-1333MHz SDRAM and an old 7200 rpm hard drive. It came with a GTX 630 and a 300w psu. I wanted to upgrade to a gigabyte GTX 970 and put in two SSD drives I got on sale so I ordered a Corsair CX 600w psu but I'm starting to wonder if I shouldn't send it back and get the 750 watt version instead to be safe. Thoughts?

The GTX 970 only requires a 500W PSU that can deliver 28Amps on its +12V rail. The CX600 can deliver 46Amps on its +12V rail, which is more than enough to power your entire rig.

Having said that the CX600 though a decent one, comes with cheap capacitors. So its longevity is questionable. If possible return it and get anyone of these:

SeaSonic S12G-550 550W
Antec HCG M 620W
XFX P1-550S-XXB9 550W
EVGA 220-GS-0550-V1 550W
Rosewill CAPSTONE-550W

Cheers!

You would be better off with a Tier 1 or 2 PSU over the Corsair.

Corsair is not poor quality, it works great with GTX970 hooked up on it. Take it from someone who has been using one for 1 year now.
It's not as good as Tier 1 and 2 of course, but it's not something that you need to avoid.

People are throwing the "poor quality psu" phrase a bit too easily around here. Tier 3 psus still are good to use with not horrible problems. The problems come when you go to Tier 4 and lower.

The main problem on CX series has been the V1. Newer V2 (around 2012-2014) and V3 (around 2013-now) are good.
There will always be "bad apples" of course. Some will fail, some will not.


EDIT: however there has been bad fans in few shipments of CX, TX and AXi power supplies. Meaning the fans in them will be malfunctioning or have loud noise.
