Vista super slow running a GTX 260, but fast on an 8800GT

So I was running fine under XP Pro with an 8800GT.

Last night replaced the 8800GT with a GTX 260. I didn't have 2 6 pin connectors, so used the molex adapters that came with the card (EVGA 896-P3-1260-AR).

I'm running a Thermaltake 430W and the rig is balls slow. Super laggy.

I pop the 8800GT back in, everything seems to do fine.

I know the card required a 500W power supply, but figured a quality one would be ok, especially just browsing around the desktop.

Think a 550W+ will do me? Or any chance it could be something else?

UPDATE

Ok so I got this Antec one recommended below, and having the exact same problem. BSODs on boot, windows stuttering, etc.

I have 2 six pin plugs going into the card. All my other drives and stuff work fine. Just the durn old video card is killing me :(

What am I doing wrong?

It's a couple of years old or so though.

Oh wow...that IS your problem. I used to have that power supply and i had lockups running a Geforce 7900GS card on it! Once i upgraded to my Antec Trio Power 550watt i had no more issues.

18A on the 12V line is barely enough to run your 8800GT....let alone a GTX card.

If i were you i'd look to get an Antec Trio 550Watt or Corsair 550Watt power supply or higher. I guarantee you that your Thermaltake is causing your GTX card to severely throttle down it's clockspeeds and kill your performance.

Yeah in reading I noticed I only have 50% of the amperage required :p

Guess I'll put that ebay live.com stuff to use

that Thermaltake unit should be pulled off the market for being a misleading product. people that dont understand anything about power supplies think they are getting a good power supply when they look at the 430 watt rating. the sad thing that psu has less 12V amps than most 300 watt power supplies.

You're talking about a power supply that is 2+ years old though. By today's standards yes, but what about a while back?

Considering it has 2000 reviews and is 5 eggs...

This is the best bang for the buck available on newegg right now. A 650Watt power supply for $59 w/free shipping! More than sufficient for what you have. :)

Just ordered one. Even cheaper than on ebay with live.

Good man! You'll be happy with it, very quiet and extremely efficient. Finally unleash the power of your GTX! :p

Yeah, the ThermalTake 430W PSUs are extremely marginal if you have a powerful video card. I have two rigs with that PSU, C2D 3.2Ghz, with Radeon X1950 Pro cards in them. I plan on replacing the PSUs with Antec Basiq 500W, before I upgrade their video cards.

I also have a newly-built rig with one of those Antec EA650 PSUs, it's running FOUR 9600GSOs, some factory overclocked. Running F@H on four GPUs 24/7. I used PCI-E 6-pin power splitters to run four cards off of two 6-pin PCI-E leads from the PSU. So far, it seems to work. I have no complains of that PSU.

Hey guys I have a similar problem,I have a XFX GTX260 c216 black and the psu is hec ZEPHYR HEC-750DR-AT 750W.
Here's the links:
PSU: http://www.newegg.com/Product/...x?Item=N82E16817339002

GPU: http://www.newegg.com/Product/...x?Item=N82E16814150330

Note that the xfx gtx260 requires 550w with 2x6pin(+12V rail) and a 40A current.The 750W PSU has 4x6pin +12 rails which is listed 19A each,will that be a problem?If yes can the 2x6pin power cable that comes with the gtx260 fix the problem?Thanks alot!

well they are selling them now plus being 2 years old doesnt have anything to do with the point I was trying to make. the point again was that the 430 watt rating is misleading because it doesnt even have the 12v amps of a typical 300 watt psu. more than half of the people that write reviews on newegg are clueless especially for something like power supplies. a lot of people buy these power supplies because they "think"they need a powerful one for even a card like an 8600gt. lol. those people never run into problems of course and would have been fine with pretty much any power supply. now some people with good systems have those Thermaltake power supplies and until something goes wrong(like in the your case) they are blissfully ignorant to the fact that they have a sub par power supply.

BS my enermax 420wt is 4 years old and has 33a on the 12v line. TT just put out a shitty product.

It was a rebadged budget 350w PSU then and it still is now. I bought one a long time ago for $9 AR.

BAH! I've been warning people away from that PSU for ever it seems. The darn thing just won't disappear from the market. :|

Though I suppose it's fine for the Pentium III that it was designed for. :roll:

Sorry to hijack this thread but I have a question for you. A friend of mine is wanting to upgrade to a GTX260 (MSI OC edition). Below are his current specs.

AMD X2 2.8GHz, 1mb L2 Cache
2gb DDR2 800? I think it's 800.
Some VIA chipset-havin motherboard/maybe a Biostar or something.
ATI Radeon X1950GT 256MB GDDR3, has 2 connectors.
WD 500GB SATA
WD 250GB some kind of IDE
LiteOn Dual Layer DVDRW.

Now, he is powering this system with a 480w Antec True Power PSU. I believe the True Powers have three +12v rails @ 16A each. I would like to know if that PSU is adequate enough for a GTX260. I believe it is considering NVIDIA recommends a 500w PSU (when using a more "high-end" system).

So will a 480w Antec True Power have enough juice to power up a GTX260? I have a pretty good idea on the answer but I want to make sure I'm giving him the correct advice.

that power supply should be enough. my entire system with a GTX260 pulls just over 250 watts under full load.

btw his cpu is going to keep that GTX260 from performing at its best. also 2 gigs of memory just aint cutting it any more for gaming.

Thank you for your response. I've tried telling him about the rest of his components (nothing I would have purchased lol) but since he already has it and doesn't want to spend much more there's not much I can do to convince him otherwise. haha

I don't think it'll be enough, the TrueBlue 480W wasn't enough to power a bare bones C2D system with a G80 8800 GTS on a backup rig. The GTX 260 uses considerably more power. It doesn't hurt to try but you'll know what is most likely the trouble part if you run into any problems.
