Is my PSU good enough for 8800GTS?

Is my PSU good enough for 8800GTS?

Rosewill 600W PSU
22A on each of the 12V rails.

It has been superb thus far.

My dell 9200 is rated at 375 - http://support.dell.com/support/edocs/systems/dim9200/en/OM_EN/YH242A01.pdf

Could I run an 8800 and a second video card for triple monitor action?

How many Amps are needed on the rails to support these monsters?

 

[happy medium]

Yes that psu will run a 8800gts or gtx.

Good to know. Thanks.

26A on 12V, but I think the BFG OC'ed cards say 28A.

Another question here, what about an old Antec SmartPower 2.0 500 Watt? It's 12v rails are a little slim compared to the newer supplies at 19A and 17A but thats still 36 together, would that work for a 8800GTS?

Rosewill isnt exactly known for making good quality power supplies. Personally I would be more comfortable running a $400 video card on a psu from forton, ocz, antec, etc than a rosewill :Q

unless the rosewill unit is just a rebadged psu from a good brand. but afaik rosewill's are rebadged coolmax's which arent that great

My PSU is actually made by Rosewill and is the top unit in their Stallion Series.

Here is the link to my PSU.

It's hard to say how good that one is. Rosewill products are rebadged versions of other brands' stuff. Some are good; some aren't. I believe they are Newegg's house brand.

Hard to say is exactly right ... my guess is you'll be ok because a strong 400 watt PSU will hold an 8800GTS on a moderate system with no trouble, but as has already been said it depends on who made the unit you have.

JonnyGuru reviewed this 500 watt model recently & it did very well.

Two part answer here ... first, based purely on power-draw I'd say the TP500 will handle the GTS without much trouble, the second question then is how brave you are feeling because I believe the TP500 is made by CWT & is one of the models with a tendency to blow out under heavy load because of overheating issues involving Fuhjyyu capaciters & somtimes taking other components out along with it when it goes.

Its a similar situation to the OP's really... can you do it?: answer = yes ... is it a great idea/would I do it? = no.

My 750W Power Top is good enough for 2x 8800GTX : )

Well, I bought this PSU before they had their Extreme Series (that's new to me). It was their best PSU at the time and it hasn't showed any signs of letting me down (hope it doesn't).

I run an OC'd Pentium D and an X850XT. What is the power draw on these and how can I use that to justify the quality of my PSU?

Just an FYI: You can't simply combine the two rails together for an accurate total of 12v amperage. There should be a combined amperage total on the badge, it will be less than 36amps.

Well first off I don't know if it was a typo or not but this is the Smart Power 2.0 500, not the True Power as you indicated. I have this PSU running my OC'ed Opteron 165, several HDD, dual optical, oc'd 7800GT, etc... with 0 rail fluction, though the draw is certaintly less than if I had a 8800 GTS attached thus my question.

I can't find a badge on it indicating total amperage for the combined rail. I was told before a good rule of thumb was combine and subtract a couple though that was just speculation.

any ideas?

Bad news is that although I may have mis-read your post about the exact model, many Smart-Power Antecs have the same over-heating capaciter problem as the True-powers (although some had dual-80mm fans instead of a single 120mm which should help w/overheating caps) & in fact I wouldn't use an Antec other then the newer models that are economy Seasonics in all but name.

Having said that, again you should have plenty of juice to run the card as long as you don't have too much else on the +12v rails, the question is how long it will hold up while running at high load/tempeture levels & what will happen if it fails ... again somthing which you'll find out if you try.

As for the actual amp output from the +12v on your PSU, my guess is that it was in the area of 26-30 total amps when it was brand-new, but if its any more then a couple years old it'll be putting out significantly less now.

1) Does all that mean that my PSU has a total of 44V?
2) How does that stack up against the others?
