PSU Choices 600W

It is a cheap budget psu with cheap internals and I wouldn't touch one with a bargepole. It's a bit better than the previous version which only had 504w on the 12v rail (this one has 550w) but it's still garbage. There's a review of it here. Do yourself a favour and buy a decent psu from the start. It's the single most important component in a pc and should not be skimped on. A good one will last you several years and through several upgrades. As RJC has suggested, take a look at the excellent Superflower units.
 
I am basically just squeezing a little more power out of a old Core 2 Quad system by adding a R9 280.

Why do I need one of the very best power supplies?

I'm not looking to overclock the system and I'm not building a super computer. If anything I will most likely buy a sub-standard I5 3.5GHz+ plus when 5th Gen comes out.
 
Because cheap power supplies are built down to a budget using poor internals, are innefficient, get noisey quickly due to increased fan speed to cool the cheap internals and if they fail can take other components with it. You haven't been recommended any of the very best power supplies that run to over £100. What you have been recommended are quality mid range psu's that we would use ourselves. If you want to stick something cheap in your pc then go ahead. Just don't expect any help when things go wrong.
 
What happened was I had a 5 year old Packard Bell from PC world. The MB basically blew so I replaced it with a cheap MATX Intel G41.

So the specs + power requirements are:

G41 Motherboard = 50 Watt.
Heatsink+Fan = 5 Watt.
Core 2 Quad CPU = 95 Watt. (Similar to a modern day AMD A4 or Pentium).
4GB Ram = 15 Watt.
2 X 7200RPM SATA hard drives 50 Watt.
1 x DVD-RW 25 Watt.
2 Case Fans 5 Watts

PLUS

1 X R9 280 = 250 Watt.

The total system power needed is 495 Watts.

All my USB stuff is connected to a hub with its own power.

495 / 600 x 100 = 83% load.

So yes I agree I need a 80plus PSU but wouldn't that Silverstone do the job without falling apart? Since its rated up to 85% efficiency? And if I needed some wiggle room go for a 650w instead?

No probs. So this superflower PSU. If my load is 495 would I be best going with 550 or 650? And will this PSU save me money on energy bills?
 
You won't be that high. The rig in my siggy only pulls a max of 420w at the wall. The Superflower HX550 is a very high quality unit, can deliver just about all of it's power (546w) on the all important 12v rail and is gold rated so is very power efficient. It would be more than enough for your pc now and even when you upgrade to a i5 in the future. If you have doubts then get the 650w version but the 550w would be more than enough.
 
Indeed, agree with pastymuncher my old i7 2700k system with a 670 GTX and the cpu over clocked to 4.4ghz plus custom water pulled 330w from the mains at full load.

Well you've convinced me good. Do you know if OCUK do Saturday delivery?
 
Hi guys.

Sorry to add onto this thread. My desktop computer started up this morning and I downloaded a couple of programmes. I was trying one and copying files over to an external HDD and the computer locked up. I reset it and it wouldn't start up again even in Safe Mode it just shuts off. I assume the power supply is packing up. I tried to go online to search for power supplies at overclockers but you click on the site and it just shows the following err:

Lost connection to MySQL server at 'reading initial communication packet', system error: 111

The same happens it you click on nay of the links above. All other sites I use work does anyone know of the overclocker site is down?

Whats the current make of your PSU and system spec?

Ocuk is having issues by the looks of things! :(
 
I'm not sure of the PSU make/model the computer was built by *********** back in July 2009.

I started the computer up after tea and it started ok and as been running ever since. I will have to keep an eye on it.

http://www.overclockers.co.uk/ is up and running again.

I changed the power supply in my old computer 600w £14 the prices quoted aren't cheap in OC well over £100.

Speccy.

You put a £14 psu in a pc!! I can guarantee you that will not be anywhere capable of 600w. You would be lucky to pull half that from it before it blew up. As a rough guide you should be looking to pay £10 per 100w for a quality non-modular psu. More if you want modular. Then there is bronze, silver, gold and platinum efficiency so each increase in efficiency costs more but you get a better psu. The psu is the single most important component in a pc and is not the place to save money. I can't beleive how many people are still skimping on the psu. It's ridiculous and you are putting the rest of your components at risk. I can't be bothered to post links because I have done it so many times in the past and am fed up trying to get this point across. Do a search for Death of a Gutless Wonder and you should get results for jonnyguru. Have a read of them and you will see why it's not to be skimped on.

To find out what your current psu is take off the case side panel and see what it says on the label.
 
Ok I took the panel off and its a Corsair TX650W I don't see any model number.

They only show 2 Corsair 650W and one is out of stock.

Corsair CS650M 650W Semi-Modular 80+ GOLD Certified Power Supply (CP-9020077-UK)

I don't really want to waste £68 if it isn't that.

I start the computer up this morning and it was running for a couple of hours.

Now a friend of mine has a Kindle but it will only play mp4 video's. I said there are video converters if you Google them. I was trying Xilisoft Video Converter yesterday when it shut down. I tried Any Video Converter today and it shut down again. I wouldn't have thought that these apps are working that hard.
