 Does my PSU have enough power for my GTS 250?

After my EVGA 8800GT randomly died after 1 and a half year of use, I got a replacement card today which is the EVGA GTS 250 (thank you 10 year warranty). The GTS 250 recommends a minimum of 450W with a minimum of 24amps on the +12 volt rail and my PSU, which is called the Channel Well Technology PSU Model (No 1S0-P500S+ Switching Power Supply, Max 405W, Peak 505W (60S), is rated a max of 405W but it also says it has a peak of 500W. So does my PSU have enough power for my GTS 250 to run it with no problems? If my PSU doesn't have enough power, I'm considering buying this 550W Corsair PSU. Buy link http://www.scan.co.uk/Products/550W-C...ar-Warrant Or I could but the 650W version of the Corsair PUS above http://www.scan.co.uk/Products/650W-C...compatible Moreover, my friend swears by this cheap 600W PSU becasue he said he used it for 4 years with no problems despite is being cheap and not being a well known brand. http://www.scan.c...l-Rail-Psu . I'm also considering this 650W PSU http://www.scan.c...erial-ATA. There's a good review on xsreviews.com of the 500W version of this 650W PSU so if the 500W PSU is recommended then would it be fair to say the 650W version would be just as good? (Link http://www.xsrevi...-ss500/5/) So which one do I go for? Or has anybody else got some recommendations for a good quality PSU which can supply enough power for my PC with it's GTS 250? Edit: I bought the Corsair TX650W PSU.

You 'should' be fine with your current psu, the GTS250 is essentially a rebranded 9800GTX+ with a few tweaks, you may infact find that it actually uses less power then your old 8800GT  Just stick it in, run a few benchmarks and see, definately not worth buying a new PSU initially.Have a look at this if you are still not sure http://www.overcl...mmies.html |

Yeah the GTS 250 is a rebranded 9800GTX+, but wouldn't it encounter probelms with a PSU that can't supply enough power? I'm not really tech savvy so all this PSU stuff is new to me. I'm leaning more to buy a new, more powerful PSU. Edited by Mr Waffles on 05-01-2010 14:11 |

I ran a gfx card for nearly 2 years on a psu that was a way under the recommended power requirements with absolutely no issues and have known others to do the same. Gfx manufacturers put PSU requirements a little higher to cover themselves, why not just give it a try and see? If you ran the 8800gt without any problems then my money would be on you being able to run the 250 just fine. After a quick google it looks like idle consumption is only 25-30w higher on the 250. Yes in theory this could be enough to tip your system over the edge if you were already running at the very max your psu could handle, but i doubt it. If you are that worried about it then just buy the new PSU and take the piece of mind, personally I would try it first, run a few benchmarks/games and see how it copes then buy one if needs be! |

Well I'm considering the 500W Seasonic S1211 500 becasue it's got fancy features like over power and voltage protection.

if your going to buy a new one, allow some overhead go for 600w etc.. otherwise you may find after some upgrading that 500 is not enough anymore. Would be tempted to do as fens has suggested and see how it goes, nothing really to lose unless you plan on selling your old psu on. If you start having random crashes you know already what the likely culprit will be unless you want to join two 12volt rails together, I would look for something with a better rating on the 12v rail |

OCCT (OverClock Checking Tool) http://www.ocbase.com/perestroika_en/...p?Download has a PSU stability test try that. But i would agree with sick and also stick with a known brand like Seasonic, Antec, Corsair etc. A good 12v rail or rails are really important. if only i had something funny or clever to put here........

I put my GTS 250 in the PC with the 400W PSU and it seems fine so far. I played L4D2 for about 2 and a half hours with everything on max except no AA or AF and no problems so far. |

Cool I would still run a couple of graphics and system intensive benchmarks just to confirm that it is all ok at max load, but it does look like you are all set. |

I was really worried that my GTS 250 failed after being used for literally less than one week. I took out my GTS 250 yesterday and used the integrated graphics and then decided today I should try and put my GTS 250 in again. It works now so I think the problem was caused by my PSU having insufficient power. I'm considering this 650W Corsair PSU from scan.co.uk http://www.scan.co.uk/Products/650W-C...compatible. Here's one review praising it http://www.hardwareheaven.com/reviews...kaging.php |

In fact, I'm leaning more to the 550W version of the 650W Corsair PSU becasue I don't think I need 650W. I don't want to spend a load of money on high end graphics and processors and whatnot so I think a 550W PSU is good enough whilst still allowing me to use upgrade to more powerful graphics cards which require more power. http://www.scan.co.uk/Products/550W-C...r-Warranty

The extra £8 ffs!! or so with that psu gives you so much more, from 41 to 52amps on that 12v rail as well as the extra 100 watts |

I got my PSU and my god the wires are so big! The Corsair TX650W is an ATX PSU so should fit in my mini-ATX case (my friend says it's a mini ATX case) but the wires are so long and thick. I'm really worried I can't even fit the wires in without clogging up my case and restricting airflow. |

I managed to fit the Corsair PSU in today with the help of my friend and it fits fine with the spare wires stuffed under my DVD drive. The Corsair TX650W comes in really sturdy packaging with the styroform blocks to hold the PSU so there's minimal chance of damage when delivered. Also it comes with a velvet bag to carry around the PSU which I think hardly anyone will use becasue who carries a PSU around? It's probably there to make the buyer feel they bought a top end product since it even comes with a velvet bag. |
