Which power supply

[BradleyKZN]

Hey all, im getting a new power supply for the pc in my specs, which power supply do you guys recommend? I have run a psu calculator and it says my pc will draw 323w in total, and both these supplies have enough amps on the 12v to power the card. http://www.ocztechnology.com/products/power_management/ocz_550w_fatal1ty_series_power_supply http://www.ocztechnology.com/products/power_management/ocz_600w_stealthxstream_power_supply both these supplies cost about the same.

stealthx 600W. i still have one here spare - it ran my system with a Q6600 @ 3.6 for two weeks, so i'm pretty sure it'll handle yours with no trouble at all.

Neither, I would get this instead: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005 (in that wattage/close to price range)

 

[Mussels]

yeah the corsair is a better choice if you can get one, single rail is better than multi rail.

 

[ShadowFold]

I would get the StealthXtreme. Fata1ity stuff is usually crap quality.

He's in South Africa, newegg doesn't ship there

 

[BradleyKZN]

So the stealthxstream 600w will be enough for my 9800gx2?

I know, I was just using it for reference.

 

[BradleyKZN]

Anybody?

 

[xu^]

i use the stealth x 600w on my main system with np's at all ,id say it should manage the gx2 fine.

In my opinion I would save a little more money and get an 850w just in case you ever want to upgrade. I bought a 600w psu for my two 9600GT's which works fine, but now I'm saving up for a Phenom II and a WC setup and I know that 600 just won't cut it:shadedshu

it will, 600W is enough for a PII and a couple 9600GTs, even with WC, if you dont use 30W fans!

@OP, OCZ is the only possibility in South Africa? i would take a corsair/PCP&C/Silverstone/Collermaster (new models)/Antec signature over an OCZ every moment. check this site for reviews:

[BradleyKZN]

Unfortunately OCZ is the only decent brand i can afford. I cant save up a bit more as i need to upgrade everything by a certain date. Also i have had this card for almost a month now and havent been able to use it since i got it.

 

[ShiBDiB]

buy anything except another overpriced fatality product... put that name on a mousepad and the price jumps its retarded

 

[BradleyKZN]

Getting the stealthxstream and coolermaster 590!

 

[Mussels]

good choices. quality PSU, well ventilated case.

Personally with your rig, I'd of gone with a new board (P45) and some decent aftermarket cooling (Xiggy or along that line) and then buy a PSU and case later down the line.

Or, PSU + Xiggy and Case + Mobo later on......either way, that board and stock cooler are surely holding back your Q9550 from its full potential. :shadedshu

yeah, i agree with you 100% but i needed the new case and psu so i could use the the graphics card. End of august is new mobo and in september its decent ram and cooler! Cant wait til its all complete! I ended up going for the fatality though, because the stealth only comes with 6 pin pci express connectors and my card needs 8. I can still change my order though

Your current psu would've been fine Bradley ....

I was more worried about the amps on the 12v rails then the wattage, i just hope i get these parts soon.

from what i know, in reality its closer to 22A on the rails - OCZ just marketed it lower, because if ALL the rails ran past 18A severe ripple would occur. so you can run or two rails higher, so long as you dont get all of em maxed out (which isnt going to happen on your PC)

 

[BradleyKZN]

On some other forum, somebody said i must distribute my load properly, how on earth do i do that?

dont use double adaptors and splitters.

Short version: if you have 3 HDD's, using all of them on one plug (which has three molex's) may be convenient, but it also means all the power is off that one rail. If you used three cables, one for each drive it would split the power more evenly.


It really doesnt matter that much, as it has dedicated PCI-E rails (it would be more complex if you used molex to PCI-E adaptors, for example)

 

[BradleyKZN]

Lol ok so one seperate cable for HDD, one seperate cable for DVD RW and then some molex's for the fans.

 

[BradleyKZN]

The psu is modular, does it make a difference?

But you can easily do that math. 338W @ load is approximately 26 to 29 amps.
