Hello guys, I am finally upgrading my old PC but my budged is kinda tight, therefore I couldn't afford a PSU. I am wondering will my 400w NeoTech power supply handle the new parts i am about to install to my PC. Here are they:

- Graphics card: Gigabyte geforce GTX 960 WINDFORCE 2GB http://www.gigabyte.com/products/product-page.aspx?pid=5503#ov (This one specifically says it should be ok, but I still need a second opinion, cause it is expensive (for me) and I don't want to waste my money.)

- Motherboard: Gigabyte B85 HD3
http://www.gigabyte.com/products/product-page.aspx?pid=4566#ov

- Processor: Intel Core i5 4460 3.2Ghz
http://ark.intel.com/products/80817/Intel-Core-i5-4460-Processor-6M-Cache-up-to-3_40-GHz

- RAM: Kingston HyperX Fury 16BG DDR3 1600Mhz

- SSD: Kingston V300 2.5", 120GB, SATA 3 (If everything above is okay, but this one comes too much, It wouldn't be a problem for me to not install it until I find money for a new PSU. So the products above are of really high priority, compared to this, so tell me if my PSU can handle them.)

Also I've used a couple of PSU calculator sites, but I'm still nervous and I would like to hear an opinion of a person, who is advanced in those types of things.
Thank you for your time, I appreciate it very much.

You need to consider the number of amps available on the +12V rail, not just the overall power. https://forum-en.msi.com/faq/article/power-requirements-for-graphics-cards says a build with a gtx 960 typically needs 20 amps on the +12V rail (and 400W total). I don't find an official site with specs for the NeoTech 400W psu, but I found this post that includes pictures of the side sticker. If that's what you've got, it can only deliver 17 amps on the +12V rail, and even presuming it's being honest about that, I wouldn't trust that psu to power your system.

Hi, mate! When I read your response I was just about to throw myself off the window for not checking that factor, but then I opened the site and looked up for my current GPU, GeForce GT430, which required 22A on the 12V rail, and so far it has been working perfectly. My question is, if I keep my current NeoTech 400w power supply, and use the new graphics card, how long will either one of them last if I use them both? I mean when I start the computer will the PSU blow or something like that? And yes, my PSU is the same as in the picture, майна.

I'd say you're already on borrowed time. NeoTech isn't in the tier list, presumably because it hasn't been reviewed by a hardware site as far as I can tell, but there are several indicators that point to it being a poor quality psu if not garbage-level:
1. 17 amps * 12 V = 204, barely half the total power claimed available on the +12V rail
2. "230/115V" input - high quality psus support a range of 100-240V input (some really high quality models handle 90-264V, but that isn't critical in most situations)
3. no mention of any power factor correction (either passive or active)

Considering it's a (probably) cheap Noname PSU...
It can fail at any time if it's pushed over it's specs.
Depending on how good the PSU is it will just fail or Worst case damage other components.
Age certainlyy won't help so I'd suggest getting a cheap Tier 2 PSU if possible

Okay then, in that case I guess I'll delay those upgrades till I can afford a decent PSU. I have searched a bit and I found this Cooler Master B500 V2 http://www.coolermaster.com/powersupply/b-series/b500ver2/ . I think it will do the job. Anyway, thank you for the answer mate, wish you best of luck!
