Big enough PSU worth it?

[Deleted member 78630]

With my system I'm currently running it on minimum power which is 450w, and if I were to upgrade to a 600w would that make a difference in my FPS and general performance?

What's the specs of your current rig?

I doubt the PSU will affect your FPS but it will make your pc more stable.

Also, rather get a branded 500W PSU than a 600w el cheapo

i LOL'd

please list the specs of your system

Not sure about your setup, but I will say no; it will make no difference. If you did not have a suitable power supply, your machine would stop working, randomly shut down, and just be a general pain. It would not slow down....

 

[Archi3]

It shouldn't make too much of a difference, but as Conradl said, if it reboots randomly and wat not then yes do the upgrade...But if i was you i would do the upgrade anyways, a crappy PSU can damage your components if it cant deal with surges as well as a good well known PSU.

It will really only make a difference if you're buying a new PSU to get a better GFX

Well thanx 4 the replies, My Rig :

1 HDD 360GB

3 Fans + Copper Fan

1 DVD Writer

2GB of DDR2 667Mhz Ram

ATI HD4850 - 512MB - DDR3 _ GPU

------------------------------------------------------------------------------------

My PC's doesn't randomly reboot and it boots correctly on start up, although it takes a while 4 the one fan to run at full speed. But other than that I get great performance,

Advice :

One of my mates has more or less the same rig as I got except 4 all the fans, but he got himself a 9800 GT and that thing zaps power, he currently has a 550w PSU and needs 2 upgrade to a 600w, hes used it 4 five months now. He's willing to 2 sell it for R250, any advice?

A new 600w will cost me around R900 from where I'm buying.

rather do yourself a favour and buy a corsair powersupply... and get it over and done with

 

[Deleted member 78630]

where can i get one?

 

[Budza]

Is the 550 on offer branded or no-name? Post brand here for advice. For R250, it sounds no-name though...

If your PC is running fine, then you dont need to upgrade the PSU, only if you intend doing some serious OC'ing and upgrading your graphics. More fans = more power. But having a ton of fans does nothing if the airflow aint right! 9800GT will run fine on a 500W, I run the GTX280 on a 600W, with OC'd CPU / Ram.

Edit: Remember a cr@p no name brand 700W wont beat a very good 500W. Check amperages on th 12v rails... very NB!

agreed. Look at the 550w and 650w corsair psus, they would be ideal for your setup

Even the 450 Corsair actually. I read a review of the 450watt where the reviewer managed to pull just over 550W out of the 450watt corsair.

I have the same question as the OP :

I am running a E7400 OC'd
2 x 2 gig Transcend dimms
ATI Radeon HD 4870
Asus P5PKL/1600 Board
Some crappy no name brand 500w PSU

At the moment, I have 4 x 12cm fans running. I intend on getting more and an additional fan controller.

What I've found happening to me is, whenever I plug in my old CoolerMasterCooldrive 4 controller, my PC makes an error beep, the code is that it's not detecting a graphics card. Now the PSU I'm using only has 1 x 6 pin connecter, I have to use an adapter from 2 x Molex into the 6 pin. I've tried changing the rails of the fan controller, but nothing works.

Do I not have enough power?

 

[cerebus]

No you do not have enough power, that's pretty obvious.

500W Should be enough, either the supply or the coolermaster must be suspect.

Ditto!

 

[cerebus]

500w would be enough on a good quality psu. A friend of mine is running less than that on a no name 450w and he had to cut back because it couldn't handle it.

I've got a similar setup to you:
E5200 @3.33Ghz
HD4870 @ 800/1100
4GB ram
etc...

All running perfectly on a 460W Coolermaster PSU. I had the same problem as you when I first inserted the graphics card. All you need to do is connect the 2xmolex to rails that are not supplying power to your DVD drive/ hard drive / fans. If you dont have enough free rails try and share the load evenly over both.

Ahhh. I will try this thanks.
