Since I've installed a new Graphics Card I've had troubles with my pc.

JoaoC · Feb 21, 2016

Since I've installed a new Graphics Card sometimes the pc gets really slow,
First I thought it was the Graphics Card tha was "too good" for my CPU, because CPU usage was about 100% when it happened, but since I've installed windows 10, CPU usage doesn't seem to reach 100% in this moments.

Here's two links for videos showing what happens, one is when I was playing and the other one was when I was just on google chrome.

CPU: AMD Phenom II X5 955

The issue is that you are having a massive bottleneck of the graphics card by the processor which is very poor.. You need to upgrade that processor or you will always encounter this problem in newer games, especially those that are cpu intensive.

what PSU do you have ???

The Corrector :

Lol that's the definition of nonsense. You think a CPU bottleneck can make your PC go totally weird? That's not how it works bruv.

For a little more information, JoaoC, can you list your full specs? Also, after you've installed the graphics card, did you do a completely fresh install of Windows 10? Without keeping any files that is?

First of all, thanks for the quick replys everyone

RARRAF: the PSU is LC6600 V2.2 600W

RCFProd: When I instaled the graphic cards (it was back in the summer) I didn't install windows 10 right away, I kept windows 7 and this problem showed up.
Yesterday I decided to install windows 10 and did a fresh install of Windows 10, I didn't keep any files.
My disk is a samsung hd322gj, and I have 8Gb of RAM 1600MHz. Is there any more specs you'd like me to say?

So looking at the power supply, it delivers below 30 amps on both the 12V RAILS. I could see the power supply not powering your system right and it could lead to problems like this, but that's not always the case. Even though It's not a heavy graphics card, I think it needs atleast a minimum of 30 amps or higher on the 12V rails. Your power supply combines 25/28 amps on the 12V rails. It wouldn't be a bad shout to replace the power supply with an actually good quality one (Ask before you buy as It's important) and see how your system responds.

RCFProd :

Thanks a lot.
Actually I said the wrong PSU, mine is LC6600GP V2.3 which has even less currente in 12V rails, 17A and 18A.

I'd like to ask you two more questions regarding this topic:

1-I've been searching about the current the graphic card need and I can't find anything about that, only about the power required (500W), so how did you know it required around 30A?

2- Which PSU would you recomend?

Again thanks a lot, I think that you found the problem

Based on the research I've done (I'm honestly too lazy to dig it back up

), it requires a minimum of: 28 amps on the 12V rail and a wattage of 500w. I'm not actually sure how accurate that is, It's reasonably measured I guess but I think you would run it without issues on a high quality 450 watts let's say from Seasonic.

So looking at the PSU you have delivering below 20 amps on both the 12V rails it is very understandable and explains what's going on. It is not safe to use in a system like that.

PSU depends on where you live really, if you're in the US it should be easy for me to provide one for you.

Even higher quality, and more wattage for only 10 USD more:

Power Supply: EVGA 750W 80+ Bronze Certified Semi-Modular ATX Power Supply ($64.99 @ Amazon)

With the EVGA B2 750w you have to make sure it is nog too big for your case. The XFX (Rebranded Seasonic) fits in almost any case.
