a b ) Power supply
May 12, 2010 4:03:23 AM

i am hoping i win the 5870 giveaway...
for running the 5870, which psu would be better?
silverstone st40f-es 400w psu (44.99 newegg)
corsair cmpsu-400cx (same price on newegg)
it would be jammed into a compaq presario sr1710nx.
thanks!

Both are good... I'd take the Corsair. I assume you already know about the 500W+ AMD recommendation.

I'd take the Corsair. But I'm pretty sure an HD 5870 system wouldn't be happy with 400W.

Shove if you must go with a cheaper PSU. the raidmax and the silverstone (@ a quick look) are the only 2 of your suggestions that have 80 plus cert they will save you money on power bill so in the long run will be cheaper & probably more inportant are more enviromentaly freindly :)

If i had no choice but the ones you suggested yes thats the one i would go for. It maybe @ the top end of what your willing to pay but as i said it will save you money in the long run over the other non 80+ psu's.

Yes, there are a number of good Silverstone PSUs. I couldn't find a review of that particular one, but here's one for another Strider series PSU.

Not really relevant, that's an Enhance built unit, the little 500 is built by Impervio.

Get that or forget it.

In your price range, a 5870 will be pushing these PSUs close to 70-80% their ratings at times, only good quality PSUs can manage that reliably. If you get a cheap one it very well may die and take that nice new 5870 and the rest of your PC with it. That Silverstone is very questionable. I have not seen a good budget Silverstone PSU yet.

Look here to see what happens to cheap PSUs:

No, bad company, poor user reviews, and no proffesional reviews.

It may have 41 Amps, but if it dramatically explodes when loaded 30 Amp, it doesn't matter.

Rosewill is actually a decent company owned by Newegg.

Also, heres a PROFESSIONAL review on the 630W version: http://www.hardwaresecrets.com/article/881/10


Right, but not the exact same unit.

He will be running 375-400w at times, so 400w/500w = 80% load which is out of the optimal range of any PSU. When you operate at below 25% or above 75% of the rated wattage, you better have a good quality PSU, not just a "good for a cheaper unit". The extra $15 will net him a far reduced chance of failure, a good buy.

i like the price, nice look, and power of that rosewill psu. afaik rosewill has some good and plenty of crappy models. is this one decentor good or crappy? thanks.
the antec 500w would be nice, but it seems to have about the same or less power, a smaller (aka noisier) fan, right?
i am thinking i should go for the rosewill. is that a bad decsiion. also, just to let people know:
-amd athlon 64 x2 3800+ 2ghz socket939 cpu
-win7 x86 ultimate
-512mb ram (will up to 1 or 2gb soon)
-wd 160gb sata
-dvdrw drive
-dvdrom drive
-no case fans

the thing is, since im not runnign very high powered components. why do i need such a powerful psu? the gpu doesnt need 500w to itself, does it? and seeing that hp was running all this off of a bestec 250w 20pinpsu (on a 24-pin mobo) and it still worked (im now on a marginally better ultra 400w p4-compatible psu)...

too bad for the link. i will give it a ceremony tomorrow it died of breaking its back cuz it tried to lift my computer.
lol jk...
the 587o will survive that...wont it. besdies, shouldnt it last longer cuz its not quite being used up 100% capacity...
oh well what should i do, OC my cpu from 2 to 2.2ghz. i tried that 30mins ago and it seemed to work fine, but i undid it cuz it was kinda piointless. anyway...

Shovenose, you must understand that the most important part of the PSU, is the performance. You need tight voltage regulation, ripple suppression, and efficiency, these are attributes that decide between a smoking PSU and a working one. The PSU has to be rock hard stable. Yes, they have about the same power on tap, but the Antec can use ALL of it efficiently and is very stable while that Rosewill likely is not.

The Antec Earthwatts series is great series and provides great performance at a reasonable price.

Smaller fan does not always mean noisier. Since the Antec is far more stable and uses better components it will not need as much cooling as a cheaper unit would.

i understand that. and i agree with you 100%. however, i will not be stressing this psu that much, thats why i eve ntought i could get away with a corsair 400cx. look at my specs. then see that ho used a 250w psu with 16amps on the 12volt rail. so do u think i need much power? i dont. also, the psu calc of extreme.outervision.com said a 400w could JUST BARELY DO it but since everyone says corsair is great shouldnt it be able to handle it?

and no im not picking a fight.
and yes, i appreciate very much the help from everyone.
but i dont get why i need a 500w psu!
thanks :)

Well lets be honest, your going to upgrade eventually right? I mean your current rig is going to bottleneck that 5870 really bad. Now, for ~$200 you could upgrade to a decent CPU mobo, and RAM that wouldn't so badly, but that would use more power.

Your current rig will do just fine on the Corsair 400w, but you will need to upgrade it too if you upgrade the rest.

Anyway, good luck winning that 5870, the odds are against you but who knows you may win.
