Radeon 4870 & PSU question

I'm running a Core i3 540, Gigabyte H55M-S2V (not overclocked) and a Thermaltake TR2 430w. I've looked over and over and I'm trying to find out if the PSU is sufficient to run the new 4870 I ordered off of newegg (it was enough to run the 8800 GTX I got used that died last week lol).

Anyone know whether this will be sufficient for 3-4 months til I can upgrade PSU?

  1. The only way to know is to try but it is not a very good psu and has a low +12volt amp rating for its size.
  2. That Thermaltake TR2 430w power supply unit may be responsible for killing the 8800 GTX graphics card.

  4. According to the AMD website the 4870 requires the minimum of a 500w PSU, your gonna be pushing it massively with a 430w. To be on the safe side I would go for around a 550w - 600w to allow headroom and avoid damaging anything.

    Hope this helps.

    It's your first time so welcome to the forum !

    You're going to need to do a bit of research into the power consumption subject, he'll have a hard time pushing a good quality 430 watt psu to 50% with those specs.
  6. Yep i agree the TR2 is far from ideal,i wouldn't use it in my low power rigs!
    Here's some for a good price.

  7. Diamond and Newegg both state 450w PSU required and I've got 29 amps total both 12v rails with this one so I'm thinking it may work.

    the 8800 gtx by the way was on its last legs when I got it for 30 bucks lol stupid thing was running 90c under load but the last guy had put really crappy thermal paste on the GPU so that is part of the culprit anyway.

    It is not as simple to add up the rails, typically total combined load would be max around 80% of that number so lets call yours 25amps! Most quality units will have that rating on the sticker in watts!
    As you can see people are pointing towards replacing the unit ASAP I did not take that direction since you are planning to do that in the near future but I agree with them. If you try it and everything runs fine I still recommend replacing it but if you start experiencing sudden shut downs and other problems then do it ASAP!

    Agreed. I can technically replace the PSU as soon as the 16-17th but I have to talk the wife into it lol. I just realized that Newegg accepts Paypal so I may be able to use the cash I have in there (if ebay ever releases it lol) and pickup a new PSU there or maybe ebay even.

    Any recommendations on a $50-60 PSU that will do the job for my setup?

    EDIT: Found this one with 2 PCI-E connectors, 40amp on 12v rail 520w Antec (http://www.newegg.com/Product/Product.aspx?Item=N82E16817371030) think that one will be enough?
  10. Yes it will do it

  12. Just an update it's working no problem so far. Gonna order new PSU in the next week or so. 4750 is running nice and cool unless I crank video settings in game up real high which I'm avoiding until I get the PSU sorted out. Ty all for the input!
