I know I'm right Running an overvolted 460 on a 450w. The SFX PSU Silverston have made to be precise.
Just thought I'd cut in here, I'd say that you have a couple of choices, the Corsair CX series (which bit-tech have reviewed, so I don't know what you guys are saying about no reviews whatsoever, there is at least one It turned out to be a good power supply for the money). The other choice, as stated before by someone else, is the Antec TruePower New. Apart from that, I wouldn't really go with many others myself at that price.
The CX bit-tech reviewed was the old Seasonic design (CMPSU-400CX) which has been discontinued (although Novatech still have some). This PSU is 80 Plus certified and a fantastic quality piece of kit. The CX my previous posts refer to is the new Builder Series which has not been reviewed because Antec won't send them out for review. Hopefully a reputable review site will buy one of each model to test. The Builder Series is not 80 Plus certified and is only "up to 80% efficient" which is marketing speak, not certification. The new series models are the CX430, CX500 & CX600 and interestingly, Corsair have used a similar model numbering scheme with them (CMPSU-430CX, CMPSU-500CX & CMPSU-600CX). Without a reputable review, how do we know the new models can actually produce the power they claim efficiently and safely?
DO NOT buy an unbranded psu, this is how I broke £700 of equiptment after the slightest vCore increase. It appears to be cheaper in the short term but when you have to buy new hardware every day it gets... considerably expensive lol
+1 to fingers post - He knows his stuff. I managed to get a Coolermaster Silent M Pro 650w on scans 'today only' for £55 a while back. As others have said above, you dont need 650w, but for the money its a very very quiet, modular, quality PSU that is running my GTX 460 + an overclocked e8400 just nicely That or any of the ones fingers linked would do you nicely.
Why are people recommending 600 watt+ power supply's? You could run the system on a 400watt. Look at the Antec earthwatts 380 watt or if you can find one the corsair cx400. If you wish to get a larger one for SLI etc look at the XFX 650 any pretty much anything made be Seasonic. Having a quick look through Fingers66 is making sense.
Thanks for all your posts, i've got it all now and running smoothly on an CX500 corsair series. running at nice temperatures too! Zak.
i see you bought already. just thought i would chime in for future reference. the gtx 460 requires 28 amps and will run fine on a 350 watt (quality) unit assuming the total system draw was less than that (which it most likely is) to become more comfortable with what psu's are quality and what aren't, read reviews. check out jonnyguru or hardocp or even the reviews on here (though bit-tech doesn't quite go as deep as the other 2). you get a feel for what psu's are known for stable, accurate outputs, low ripple, quality capacitors, internals...all that. single rail vs multiple rail...read and learn...good luck with that unit. corsair's name is on it, so that means something, but they are the vendor. they didn't manufacture it, and although they are known for putting certain quality control measures in place, again, no one has cracked this puppy open. i wouldn't press your luck more than 2 years or so on it.
The reason for buying a PSU with redundancy is for maximum efficiency (PSUs are most efficient around 50% load), and also to save upgrading PSU if hardware gets updated.
Sumvision sell loads of stuff, it's just that you see most of i on sale at questionable market stalls for £10. Get a seasonic S12II, antec Basiq or Corsair CX series(in that order of recommendyness). Ah, see you bought one, nvm then.
Wow, must be the first Builder series purchase on here. And after Fingers recommended an S12II AND a bargain Truepower New. Wonders never cease.
Can someone help me? I have a corsair cx400 and on recommendation from a tecky bought an MSI 460GTX. The install guide says I need at least 450w and my cx400 says it's 400W. Do I need to to upgrade my PSU
No you don't. The 450W minimum is there because the manufacturers don't wanna be sued when crappy cheap PSUs aren't able to run the cards. A good quality 400W PSU can run it with no problems. You have no need to upgrade from your CX 400
