How many watts should my new PSU have?

[trevorman1]

Hey All

I am running

Intel Core 2 quad 2.8 Ghz
Nvidia GTX 260
4 Gigs ddr2
WD 500 Gig HD
Dvd/CD drive

My current PSU makes loud noises and I believe is the cause of my BSODs. I am replacing it and want something that will be reliable for a few years. I am thinking of the Corsair 450VX 450W ATX12V

I don't know if this will be enough. I will NOT be adding any extra components so I do not need extra head room. Any advice would be appreciated

Thanks

if u decide for the 450 anyway, it may work, but u will be cutting it very ZVERY VERY close!!!which is not a good idea!

For around the same price you can get an Antec Earthwatts 650. Not a lot of flash but a very very solid PSU.

true. i would say that the antec has a little bit more power but not really that much.


if you read the newegg reviews you can see that several people have had buzzing problems with the CORSAIR 450VX that the OP wanted

It's cheaper than the Corsair you listed, granted it doesn't have the nice single rail at 41 amp, but I would say the 3 rails with 2 22 amp and 1 25 amp rail would be a decent step up in power. I'm too lazy to get under my desk and open my case to check the sticker for total combined 12v amps, but I think it's over 50 amps.

maybe if u laugh urself to death u will be less lazy and check insdie ur case!!!

Doubt it. I like to work smart, not hard. I'd google it before I crawl under my desk.

This is a fairly decent PSU calculator: http://www.antec.outervision.com/PSUEngine

The Corsair 450VX is a highly rated power supply. Here's the review that convinced me to get one: http://www.hardwaresecrets.com/article/540

Give the article a read, but I'll throw in a couple quotes:
"This power supply is manufactured by Seasonic. ... After opening this power supply we found out that internally it is identical to Antec Earthwatts 500 W, but using better electrolytic capacitors."

"...a relatively inexpensive power supply that even though is sold as being a 450 W unit can deliver up to 570 W at 48º C – in fact Corsair could have easily labeled this power supply as a 500 W unit, but they preferred to stay on the safe side."

 

[shovenose]

ok then...but i still like my 550 watt recommendation, even though i do realize that the 45owatt would probably do the job just fine.

You seem to care more than I do. I say you go for it and prove my "I think" crappy memory wrong.

 

[shovenose]

well, i googled it, i looked on the antec website, and couldnt find it!!!!!

Where's your google-fu?

I found this thread http://www.tomshardware.com/forum/265503-28-antec-earthwatts-current-desktop-setup

jsc thinks it give him 52 amps combined. I looked at the pics on newegg it seems it has a total output of 540w on the 12v rails. By my limited electrical math that would put it at 45 amps.

Psst, jsc has an Antec True Power Trio 650 with 52 amps combined on the +12v

 

[calinkula]

Eh, jsc didn't specifically say that's what it was. I didn't look farther than the Earthwatts title and someone saying "Antec" + "52 amps". I would expect someone to be specific if they have something different than what's in the context of the conversation. But this is the intertubes and English = EPIC FAIL for most people.

How about a nice unit with 40A for the same price as the Corsair 450VX? Solves your power issues and gives you a good unit at a nice price. Seasonic released a nice 520W unit that is the same price as the 450VX and got a great review from jonnyguru
