Hi All

Looks like its new Power Supply time. But not sure what size to get,this is what I am running

2 SSD
3 HDD
6 Case Fans
AMD FX-8350
1 Dvd Drive
16Gig of Ram
Radeon RX-460
TV-Card

So what do you guys think i should go for

Thanks All


:)
 
Thanks for that i was thinking maybe this time i would go for a 550W PSU just to cover me a little.

Is the Superflower about the best at that price or is their something just as good but maybe cheaper.

You can also have a look at the Antec Truepower Classic 550W. it's the same price, but is based on a Seasonic design:

Both are very good PSUs. You could probably get away with the Superflower HX450 though:

It's slightly cheaper and should still be more than enough for what you have. Which RX 460 do you have as some of them do use a 6-pin power connector and therefore draw more power?


Using this one and their is no 6 pin on it

The PC has started to feel sluggish and slow and for no reason it would just reboot itself while just sat their on the desktop doing nothing. Then when I was video editing it would do the same. I don't play many games but now and then i play Farcry 1 and it locks up after a few mins. Also my sound would just mute while watching a movie and I would have to restart the movie.


Then the PC would boot up and there would be no picture on the screen so I had a spare graphics card I put that in and it worked so I got a new card but it still feels slow. I know its not the most reliable thing in the world but I checked my system using HWMonitor and Speccy and then I seen this.

I don't have one. I did think about getting one,is a multimeter a good way of testing it as i think the problem is when i start to draw more current from the PSU that's when the problem starts.
 
Getting an multimeter will be a good investment, you can check the voltages at the molex connectors to see what the 12v is reading.

In the past when I looked at my 12v in HW Monitor with a Gigabyte board I get silly readings.

Can the PC be running while using a multimeter because i think it might show up as fine until i put the PC under load then i think that's when the power drops off

Which ones runs stuff like USB is that the 3.3v one as i think that's why my sound cuts out on movies
 
The 3.3V could be tricky to measure, as it's not on a molex connector and you're motherboard doesn't have dedicated probing points.

However, USB is powered off the 5V rail, so you're in luck.

If you've got USB speakers, I'd suspect that there could be a driver issue to blame. Do you happen to have them connected to a USB 3.0 port? That board uses the Etron EJ168 and I remember having a few issues with it on another system.



Its a USB Dac and its just running off a normal 2.0/1.1 port and its been fine for ages but every so often it just cuts the sound off that's why i was thinking it might be a PSU problem

Just had a look at my molex connector and all the wires going into them are black in fact every wire coming from that PSU is black. Am I right in thinking that on a Molex the 2 in the middle are the earth's and the ones on the ends are the +12v and the +5v
