Graphics cards and power supplies

Hello, my current power supply is 450W or 500W peak, you can find it here http://www.plugloadsolutions.com/psu_reports/LITE-ON_PS-6451-5_ECOS%201900_450W_Report.pdf
I am going to upgrade from a Radeon HD5570 to a 7870 or a 7850. My question is would my current power supply be able to handle one of those cards or should I upgrade, and if so can you recommend a (preferably cheap) power supply?

  1. What else do you have in your computer?
    CPU, memory, harddisk(s),cardreader, dvdburner(s),blurayplayer/burner etc....
  2. A 7870 would run just fine on a quality 450w unit. HOWEVER, Lite-On is not even on the Tiered Power Supply list, so I'd stay far away!

    Pick a power supply in Tier 1, Tier 2, or Tier 2B. I personally use an Antec Neo Eco, its a great Tier 2 supply. Antec, Seasonic, Corsair, XFX, Enermax are all great brands and between them you have TONS of supplies to choose from. Anything from those brands with at least 2 6-pin PEG connectors would work great for you!

    Power supply is the most important part of your computer, don't risk all your other parts by skimping on it!
  3. That power supply is putting out 27 amps on the 12v rail for a total of 324 watts. Since modern computers mostly depend on the 12v rail this is roughly what a quality 350w power supply would provide. So that power supply is either old and low quality or just low quality. I was not even aware they sold power supplies.

    So an HD 5570 would probably work fine. I would not trust it with an HD 7850 or 7870.

    AMD recommends a 450w power supply for an HD 7850 and a 500w unit for a 7870.

    Due to a very good sale the Seasonic M12II 520 is only $59 right now with no rebates to fool with. Seasonic is recognized as one of the best if not the best makers of consumer power supplies. This unit is also modular.

  4. Crap man, my PSU is only 5 months old and I might pick up that SeaSonic. That's an epic deal!
  5. Imo the Corsair CX 500 is a good choice as well.

  6. I know it. They don't go on sale for almost half price too often.

    The Corsair CX line is made by CWT and that line is not their best effort. They are Corsair's budget models and reflect that in quality. They are the only Corsairs to make tier 3 of the quality list.

    For the same price the Seasonic is a no brainer.

    Im from Europe, never heard of Seasonic before, do they sell under a different name overhere?

    They don't sell too many models, they make a TON for other brands though. Most Antec PSU's are Seasonic, Antec doesn't actually make any PSU's themselves AFAIK. Seasonic is a VERY high quality OEM, the best IMO.
  10. Seasonic makes some Antec power supplies. Delta is their main OEM.

    Seasonic is an actual manufacturer. Many brands like Corsair, Antec, PC Power and Cooling, XFX ect. don't manufacture anything. They just rebrand power supplies made by the companies that actually do manufacture them. If you really are curious as to who makes what this is the best database on the internet. Also has links to the real review sites.

    It's very up to date. It's not a perfect list but it is very good overall.

    Great choice. You do notice you are ordering one from newegg.com and one from newegg.ca right? ;)
  15. Yes lol the graphics card was from .ca I just used the link someone had above me out of laziness
  16. Ok you are good then. I was not sure the PSU would have been on sale in Canada too.
