Hello! I have quite low fps with gtx 960. I have:
I7-4770 3,4ghz
2tb seagate
beatsaudio 7.1
gtx 960 gaming 4gb (replaced r7 240)
460w HP power supply

Is this really enough for my system? Partpicker says my computer needs ~350w power supply.
I have quite low fps. example minecraft singleplayer. i have fps around 100-400 and it should be around 500-800.Whats wrong. Can somebody smart answer? I heard theres one 6-pin for CPU and one for GPU. I don't know if i mixed them up.

Thanks for advice!

Some off brand psu is what the problem is. That psu can't provide enough power. It's a 4pin for the CPU and a 6 or 8 pin for the GPU. That PSU can't output enough power for your PC. I would get a seasonic PSU, something around 500w.

That is my build with a 4790K + GTX960 + h100i only minus one stick of ram. I run it off a CX430 (430watt PSU) and it runs fine, note that PC part picker doesn't add wattage for most peripherals or things like the optical drive. I bought the CX430 because I got it for $20USD new and it is sufficient.

Reports have shown that when they fail they are not likely to cause subsequent damage to other components. I have ran it for about 7-8 months now with no problems.

I wouldn't see that you should be having issues there and you might have an issue within the operating system. However if it is old like my 12 year old Dell PSU it could be running less than optimally.

That power supply is not powerful enough for a GPU. Also, Do not buy corsair CX series for a gaming system. They are meant for low end systems and cannot support a decent gpu very well. Get a SeaSonic or XFX power supply, as they are far higher quality. I do not know why you expect such high fps is Minecraft. Unless you are running low render distance, 100-400 is normal.

I'm not disagreeing with you on the fact that its not the best PSU but I think a lot of people are just hoping on the bad wagon with that one. If you can get a better PSU I would strongly suggest it but $20 new from a good company is hard to beat. The GTX 960 doesn't use that much power and I have gamed a bit with it without any problems. Locked at 299 FPS in CSGO, 50-65 FPS in rust at maxed out settings, Batman AK is around 60 frames most of the time. I've never had a problem due to power issues and I have a ton of stuff hooked up to my rig. I would agree that you should shop around for something better BUT on the other hand, I went with this $20 PSU so I could lighten the load on my wallet while I save up for something better. All in all what I am saying is I don't think its as bad as everyone says and crys about and $20 dollars is such a minimal investment that I think it is a great PSU for the money and as a temporary solution. I have done hours of gaming on end and the PC is on 24/7 for the past 6-7 months. Now if your going to buy it at MSRP at $40, throwing an extra 20 or 40 on that to get some way better would probably be the way to go. But these go on sale every few months.

An i7 can draw nearly 1/3 of the power output of that PSU. The GPU the same. Then you have the motherboard, the hard drives, and the RAM. The recommended wattage is 350w. A $20 430w PSU can't handle being at 80% load all the time, especially when it's less than 80% efficient.

There is no such thing as a power supply not outputting enough power. A power supply does not supply power, it uses voltage to cause electric charge to flow. The output voltage is what is important, how stable that is, and that can cause problems, but power is not a substance. A PSU is not a squirt gun with power inside of it - that's the wrong picture you have in your mind. Any power supply technically can deliver enough output current to merit 1500W of power, but some PSUs will either burn, have unstable voltage, or turn off from protections before such a thing happens. In conclusion, power is not a thing that runs out.

In this situation, low FPS would not be caused from the PSU. A PSU can cause freezes, BSOD, shut downs, and such, but low FPS in a video game is typically another issue, often software related.

I don't see why the OP expects his FPS to be 500-800.

No, it's really not. I understand how power supplies work. I know that any power supply can, theoretically output 1500w, but the problem is that If you have a power supply that doesn't output enough wattage, you will have issues. One thing i will say is that optifine will greatly increase your FPS, especially if you turn on multi core chunk loading. What I'm saying is that it literally is incapable of outputting enough power and not exploding at the same time. That's what I mean when I say that it can't output enough power, not that it is somehow limited in the power it can provide, but that it's limited by the protection circuits.

Well, it's best to speak with proper terminology, because this makes it more confusing to users who start getting the idea that power supplies can actually run out of "power". If a power supply explodes by being overdrawn, that is not a limitation of the protection circuitry but the ratings of the components inside.

I don't know man. Honestly with real world experiance my 4790K is OC'd at 4.6 and my GTX 960 is OC'd a bit too (don't remember how much), with about 5 hard drives, two flash drives, xbox controller, headset, speakers, optical drive and the h100i set to keep up. I have had 4 games going at the same time; RUST, CS, MGSV and Evolve. I kept alt-tabbing between them so it wouldn't drop the other process to focus on the main one and things did get slow because of that but honestly not badly. I had this going like this for about 1-2 hours, then let it focus on one played some CS and then did it again for about another hour. In all honestly I have never had a problem. Maybe I got lucky and they misbadged one of the $200 units as a CX. I leave my PC on 24/7 since I got it and only shut down when I want to for installing things and such. And I have never had a problem. Its been through 2 power outages with a surge protector at the wall. I put this rig through its paces cause I bought a 4790K and GTX 960 which none of this do I really need. So I like to see what it can handle. If it caught fire today I would say I got my monies worth and wouldn't even be mad.

I really do feel a lot of this talk though is more theoretical/myths than real world experience. I was gunna buy an HX850i or AX860i and then throw this guy in my Dell but right now I can't see any benefit from doing so. And would rather put the money towards some new shoes or dirt bike/car parts.

Keep in mind that you can get a crappy PSU that lasts a very long time and you can get a good PSU that lasts a short time. There are so many different things that can fail, and just because two units use the same components doesn't mean they'll last the same amount of time. Just look at the silicon lottery with CPUs - same goes for all the integrated controllers in PSUs. Same with capacitors, some just can be better than others by chance, the good ones out of the bunch. And some may be bad out of the bunch.

100-400 is not normal for that card and cpu. I have an i5 6402P and a GTX 960 and I run 400-800 at 8 render distance and max graphics. Maybe get an EVGA 600w power supply.
