PSU Purchasing Guide-----Revision 1.6

[rickyman]

my pc config:

p4 2.8c @ 3.5 ( not stable enough to get a new psu for it)
ocz pc4000 (ddr 500)
ati 9800 pro/xt
2 x 80 sata hd raid 0
200 ide hd
dvdr drive
1 intake fan
1 fan controller
msi 865pe board

i am going to buy 6800 gt/ultra agp later.
i am going to buy like 6800 gt pci-e in the near future.

should i buy ocz 520 powerstream or 600 powerstream?

so i need at least 1 pcie connector.
i want at least 7x 4 pin molex connector .

 

[drpootums]

I would just get the 520 for that. I'm not quite sure off the fly how many molex connectors it has, but the 520w version has more than enough power for all of that IMO.

I have an Aspire 500watt powersuply, is this any good for a AMD 64 3000+(Might get OC) and a 6600, 3 optical drives, 5 lighted case fans, floppy drive, 1GB of ram and a couple usb devices?

Yeah. The 520W has about three times the power you actually need, so might as well stop burning money at $150.

 

[drpootums]

Anyone have any other ideas/sections i could add?

bump?

drpootums: Just reviewed your ModStream 520W for you: http://www.jonnyguru.com/modstream/

Nice PSU. I'm giving it an Editor's Choice award on SLCentral.

Already started on the PowerStream. "6 individual power rails for cleaner power." Too bad they can't have seprate rectifiers to keep the voltages seperate.

I cranked one rail high and one rail low just to see what the rails would do and the results were so wacky, I had to take video!

Notice how ALL of the rails are bouncing around even though just one voltage has been adjusted down to no-load.

What's funny is the PowerStream did this dance more than any other power supply I've ever seen. Usually, if I lower the 12V, the 5V goes down to about 4V, etc., but it's stable. If I lower the 5V, then the 12V goes down to about 9 or 10V, 3.3V goes down to 2V, etc., but it's stable. I've never seen this before.

 

[drpootums]

Ohh...haha...anyways, thanks for the high marks on my PSU, makes me glad i bought it! I've been very satisfied with it so far!

 

[jonnyGURU]

Yeah... I thought about giving it a "9" because I didn't like the cables, but considering how much power it put out and how quiet it was and how relatively CHEAP it was, I had to bump the score a bit.

 

[drpootums]

bump...this is what happens when you spend more than a week away from AT i guess....

Zalman should be pretty high up too, IIRC AnandTech or some other good tech site did a review of it and it delivered well beyond rated capacity while maintaining VERY quiet operation.

 

[drpootums]

bump...

 

[ShadowBlade]

wered the sticky go?

Bump to keep this useful thread alive.

LOL @ putting OCZ #3 above Sparkle/fortron/seasonic gimme a break.
Explain to me placing a OCZ PSU with only 75% efficiency above Seasonic with 87%? One with cheap china cap over one with high end Jap rubycons? One that's noiser over one that quieter? One thats puts out less power vs more?


OCZ
http://www.driverheaven.net/reviews/ocz600w/

is a budget PSU made by topower,

http://dansdata.com/top686p6.htm


same as raidmax http://www.silentpcreview.com/article225-page2.html

Are they good?

Now, here's a list of PSU manufacturer's i would stay away from:

-Raidmax

Guess not, since you say so, even though they are the same. Look carefully.

How about Tagan, Globalwin, BeQuiet, Aerocool, and A+GBP or whatever other marketing company wants to pay Topower for a PSU... All should be #3 then.

:::SIGH:::

I suggest going to a real site like SPCR and studying VERY carefully their scientific PSU methodolgy before guessing. That's all thats going on here, guessing and a popularity contest with whomevers marketing sunk into your heads wins and what ever you own of course. Sorry if I come off a little strong but I don't like guessing and I hate marketing even more.

Now, like i said, those are just my opinions

Correct! so what purpose does this thread serve again? Needs hard data
