Hey everyyone!

I just upgraded my power supply from my old 600 watt one that blew out to this one:

http://cgi.ebay.com/ws/eBayISAPI.d [...] 0184657245

I wanted to know if the power supply has enough power to run a new GTX 280 or something real good. I don't really know what the requirements are other then the new power supply having a 6/8 pin power connector and 750 total Watts. Thanks


I was thinking of getting like a:

or

http://www.newegg.com/Product/Prod [...] 6814150343


I have an ATI Radeon 4850HD 512mb gddr3 now that will definately work with it, but how about the newer models with my new PSU.

Thanks-



Also don't forget to scroll down on the 750W power supply link page to see the detailed specifications of it to help me out!

Where are people finding these things??

Its absolute crap...would throw it out asap. There isnt even a company website...nada
Based on straight numbers cause they never show the sticker theres 2 22A rails. Adding them fully (and its less then that cause u dont just add) u get 44A which is around 530Watts. The actual 12v wattage is probably realistically around 450ish...
It might run future stuff, but i wouldnt do it based on quality

so will it run my radeo 4850hd 512mb gddr3 well now? probably better then my older 600 watt psu, that was worse.

visiontek hd 4850 512mb gddr that I have now, it was kind of cheap and has a lot of power and had the right power connector and stuff
April 29, 2009 4:10:08 PM

and it was just a replacement for my old burnt out power supply, so, yeah

That PSU is garbage. It might work, but for how long, and what will it take with it as it dies? Not worth it. Choose a PSU from Antec, PC Power & Cooling, Corsair, Seasonic, or Enermax. For one card, 500W-650W is enough.

April 29, 2009 4:22:07 PM

well it was just a replacement, and it will run my ati radeon 4850hd and everything right? cmon the company is not really known I guess or whatever though
April 29, 2009 4:28:40 PM

It should run it perfectly for the card I got now right, it only needs a 450 watt psu, the radeon 4850hd 512mb gddr3 that I have now anyway, so there shouldn't be a problem. As far as a better video card is concerned? what about?
April 29, 2009 4:36:57 PM

a 450w psu for all the system, make sure it is 80plus though.

and what are the other parts in the system?

if the CPU uses more than 120w for amd or 90w for intel then forget about using that 750w psu.

that is my new 750watt power supply specs, and I have a Conroe E6850 duo core 2 3.0ghz processor. Thanks-
April 29, 2009 4:45:19 PM

It will work and everything right?
April 29, 2009 4:46:00 PM

All I needed was a replacement power supply and it is 750w and everything, so should it be ok?
April 29, 2009 4:47:56 PM

what motherboard have you got?

how many HDD's and optical drives do you have?, how many fans do you have?
April 29, 2009 4:49:01 PM

I don't know a lot about power supplies and what not, but it should run it normally and stuff right?
April 29, 2009 4:50:45 PM

I have 2 HDDS, a 80 gig and 160gig, 1 dvd-rw drive, 2 case fans and my motherboard is a new Nforce 650i Ultra non-sli single radeon 4850hd gddr3 pci-e card
April 29, 2009 4:54:06 PM

mf2385 listen, that PSU is crap, it will probably work, but, how long is any ones guess, and when it dies, it could take your whole system out, listen to jtt283, get a good brand, one of the ones he suggested

btw, i would return the PSU (if you can get refund), or just toss it
April 29, 2009 4:58:57 PM

It should work fine with my system though and everything right? I am not getting a better psu because i don't have the cash for it right now, and if it dies then I will get what's due to me. All I want to know is it will work fine with my computer and everything for now and for awhile? Why do you guys not have any kind of faith in another company, maybe it will work for a long time and be really good? How do you guys know? Maybe they are just unknown. The brand.
April 29, 2009 5:03:07 PM

basically if something happens, i will deal with it then. no money right this second or time, I need my computer back up, period.
April 29, 2009 6:08:15 PM

but if it dies then you'll have even more expense
April 29, 2009 7:03:18 PM

but it will handle my current system, and that's all I need for now, thats the consensus correct?
April 29, 2009 7:03:49 PM

that's what they are telling me over at Guru3d, it will handle my current system fine.
April 29, 2009 7:17:52 PM

weve answered that already....
Its yes

But none of us would use it. Id let my computer sit without a PSU instead of taking such risks
April 29, 2009 7:23:10 PM

lol nothing will happen to it, if it does it's covered.

I want to know if that will work with a newer video card like the radeon 4890 1gb or gtx 280 or 285, with it's new power requirements and stuff..

How many times do you have to ask the same question?


As the others have said, that PSU is garbage. You said yourself that you know nothing about power supplies which is obvious by the fact that you keep mentioning that the video card you have requires 450w. Watts mean very little, in fact one of the first replies mentioned what you should look at instead of watts but you overlooked that.

You mention that this is to replace a PSU that died, I've never had a PSU die before. I'm thinking that you are used to buying cheap and expect that out of it. That's not to say that Antec or PC Power never have units die but it happens much less often. The biggest concern is with stable power. Cheaper PSU's have greater fluctuations in the power provided to the system which causes more stress on other components. Pushing the system with gaming and/or overclocking will accelerate the degradation of your components.

As the others said, that PSU will work. I see it happen a lot where people spend a bunch on components and buy the cheapest case and PSU they can find. An inexpensive case is fine but a cheap power supply is capable of taking your whole system out.

Will it work with your current hardware configuration?

Probably. It *should* power everything you have now. But you admit you know the risks, so I won't repeat the warnings others have given.

Will you be able to upgrade to a more powerful video card?

Doubtful. You should upgrade the PSU to a quality brand before spending money on another video card.

What size/resolution monitor are you running that 4850 on? What games are you running on it?



I really cannot believe the manufacturer labeled that PSU as 750w with just 2x 22A rails... that is f*cking ridiculous.

Let me be clear, you did not buy a 750w PSU, you bought a crappy 450-500w PSU with '750w' on the label.

LOL, mtyermom I like the Tool reference in your quote. Stinkfist, my kind of love song.
April 29, 2009 9:00:44 PM

i play at lower resolutions 1280x1024 and 1024x768 mostly, I don't have a huge screen 17', it will run everything though for now and for the not-to-distant future is good and fine for me, and I am not upgrading my video card for awhile anyway probably 6 months. It will be fine until then anyway.
