So I have a 400W PSU right now (12V1 – 10A; 12V2 – 14A). [codeGEN 400x]

AMD Phenom II x4 965 Black (@3,4GHz) 125W TDP;


Gigabyte NVIDIA GeForce® GTX 650 OC connected through 6-pin;
1 PATA HDD; 2 SATA HDDs; [1x WD Caviar Blue 320GB; 2x Seagate Barracuda 7200.9 160GB]
1 PATA optical drive that I rarely use [sony Optiarc AD-7173A silver color] (it's also got labelflash, which I haven't used at all)

 

Upgrading my GPU to: 

ASUS NVIDIA GeForce® GTX 660 DirectCU OC [link]

 

Will my current PSU be able to handle it? 

I will buy a new PSU – Corsair RM550 (I want the 0RPM option) – hopefully around mid-April.

CPU: Intel® Core™ i7-4790K (4GHz x 4 cores/8 threads);

RAM: 32GB DDR3 1333MHz; 

Graphics: EVGA GeForce GTX 1080 SC GAMING ACX 3.0; 

MB: ASUS Z97-A/USB 3.1; 

Storage: 512GB Samsung 970 PRO NVMe SSD.

Windows 10 Pro 64-bit.

You should be okay, just don't do any heavy overclocking. Or just wait to get the PSU with it to be safe.

Ah, miss read that. I thought it was a model number, I would recommend you buy a new PSU and then the GPU.

Don't. Go with a lower powered card like the 750 Ti or get a new psu first.

Well I already bought the 660, so that means I'll have to wait till I can get the PSU (side note - I'm planning on getting it on my birthday - April 15th, or a bit later. So, yeah...)
