Recommended PSU?

post #1 of 8
Thread Starter 
I recently purchased a GTX 560 OC'd card, and noticed that the required PSU was 500w. I know those minimums are a little exaggerated, but I dont want to have any problems, and Im thinking about starting to overclock soon anyways.

The only knowledge I really have about PSUs are that Corsair and Antec make some decent ones?

My system specs are below, just wanted some help with deciding what wattage I should go with, and then what specific PSU I should go with

Im assuming I need a 550-600ish watt to be safe, but you guys would know better than I do.

Thanks in advance

If your 430W PSU was a decent one you wouldn't need a new one now.. your PSU is a poor HEC unit with a 12v output of about 250W, so essentially a highly overrated 300W PSU(at best).

A 600W unit will suffice if you want SLI, otherwise you don't need more than 450W.

What's you budget and where are you buying from?

I dont really see myself using SLI, but definitely want to leave some room for future card upgrades.

Preferably well under $100, but I dont want to skimp on the PSU, so If I have to spend some money on it I'll be willing.
Buying in the US, most likely from some online site (Amazon/Newegg/TigerDirect)

You don't need to spend 100$
OCZ ZT 550W @ 80$, solid GreatWall made unit, fully modular.
Antec HCG 520 @ 63$(with promo code), solid Seasonic made unit, not modular

And here's a premium unit too, in case you want to spend 100$
Lepa G700 @ 100$, Enermax Modu 87+ inside, excellent Gold unit, will easily run a HD 6990 or GTX 590 so there's no upgrade restriction

Nice, I think Im going to go with the Antec.

One last question though, how do I know which cheaper PSUs arent good quality? Because there are some pretty cheap ones made by well known manufactures.

Thanks for all your help

Yeah, that 430W Thermaltake is weeeeeeak. It's overrated and has pathetic efficiency. That thing was kicking out insane heat just idling with a Pentium D and 8600 GT. An Antec EA 430W would be good for that setup but pretty close to its limits. An Antec NEO ECO 450W would be pretty adequate.

Pretty much anything you see my those cheap brands like Raidmax, Diablotek, Logisys, Broadcom Corp, Apevia, etc. are complete garbage and should never be used. If you use newegg and go to the power supply section and sort all the power supplies by cheapest first, it is a pretty good rule of thumb to ignore every power supply on the first 4 pages. For every good power supply company, there are like....20 bad ones

But then what about the generally "better" companies?

For example: http://www.newegg.com/Product/Produc...S500-PCARD3-US

That PSU is only like 30 dollars (after rebate) on some sites, and based off customer reviews looks alright, but how do I know that it isnt 30 dollars for some negative reason?

Cooler Master's lower end units are not very good. They aren't as bad as say, Diablotek but their lower end units should be avoided. They make some really good higher end units though. It is always very important to not skimp on the power supply, spending more money NOW is the better option
