Do i need new psu?

[michael Q]

well im extremely new with computers so you may need to bare with me and my psu might not even be the problem.

Well around 2-3 months ago my 500w psu died and my computer wouldn't turn on and all that (i know it was my psu because i did the paper clip test) so i went immediately and bought a new psu (another 500w although this one only cost £16 which seems very cheap) and ever since i got this new psu ive noticed the performance on my pc while playing games drop dramatically i used to play skyrim and battle field 3 on medium/high settings and got atleast 60fps but now i get 40fps on the lowest and this trend goes for all my games im just getting half the fps i used to and also i cant even play bf3 anymore i get around 10fps on the lowest settings.

My Specs:
CPU: amd a8-6600k apu
GPU: nividia gtx 660

P.S task manager is telling me im using at least 50% of my cpu when im idle and using around 100% when im playing a game so it could also be my cpu and please respond if you can any help at all is greatly appreciated.

You left out the brand and model of the PSU which is important in this case.

Here is a list of PSUs listed according to quality - http://www.tomshardware.com/forum/id-1804779/power-supply-unit-tier-list.html

From what you describe it does look like a marginal PSU. Get a new one from Tier 1 or Tier 2.

Well, Those aren't 2 extremely wattage demanding parts (CPU and GPU) but buying a $16 PSU was not a good move. Cheap PSUs are not ideal for gaming computers at all. You will probably only get about 300w from that PSU, if that. What brand is it? You could possibly be underpowering your parts which could cause future dammage, decrease the life of your component(s) or cause them to act crazy

Just a thought, possibly an incorrect one, but it almost sounds like a conflict between your on-board CPU-integrated graphics and the NV 660; or you have connected your monitor to the incorrect video port. Silly as it seems, it is worth checking to be sure that you have connected to the video card and not the motherboard video-out ports and that it is a solid connection.

my monitor is connected through the right port (i checked to make sure lol) and my cpu is an apu i think so i have been told to make sure the gpu part of it is disabled but i dont know how to do that

and ubrales this is the exact psu i got: http://www.amazon.co.uk/gp/product/B00642F8AU/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

Get rid of that thing ASAP. It's like picking a surgeon or sushi because it was the cheapest.

Take a look here http://www.tomshardware.com/forum/id-1804779/power-supply-unit-tier-list.html get something from the first 3 tiers. Will be double or more of what you paid for that silver PSU shaped box.

Yeah, that power supply is a real stick of poo. You do not want to mess with bargain-basement PSUs; they will eventually fail and can severely mess up your whole machine when they do.

 

[Shamar Holtz]

Mhmm...It's like a suicide bomber tbh. Or some would say it's a ticking-time-bomb, It will explode one day and kill some of your other parts while it's going up in flames ^_^

 

[michael Q]

my problem is that i couldnt find a psu that fits in my case that was the first one i found

 

[capt_taco]

... so in other words, the answer to the original question is "yes," although that may or may not have anything to do with the actual problem.

Honestly, I don't think the power supply has anything to do with that. A poor power supply shouldn't cause FPS drops; it either provides enough power under load or it doesn't, and therefore either the GPU works or the system shuts off. This is something different.

That looks like a standard ATX power supply, look at the screws, there should be 3 in the corners then one maybe an inch in on the top left if you are looking at it form the back. The description on the one you got states ATX, that is the most common power supply layout.
