I have an i-ball Workhorse cabinet,the default power supply says LPK230-450 no mention of any wattage is there, I want to buy a graphics card Radeon 6670 or GTS450, but they require 400W.So I was wondering if my PC have enough firepower to adapt these cards.Any help?

More about : psu wattage lpk230 450

I don't know if its even 400W ,the SMPS does not say anything about wattage it can be 250W as well,the cabinet's box also does not say anything about wattage of the PSU.

LPK230-450 is 230volt max and 450W (spec your PSU) and you will buy graphics card Radeon 6670 or GTS450 that need minimum is 400W (good PSU) .. over 50Wattage from recommendation is more good

Sounds like a suspect PS. Upgrade to a budget priced Antec VP-450 for under $40. Currently, this is the only PS that is not 80 Plus certified that I would buy.

LPK230-450 appears to be manufactured by Linkworld. This particular model doesn't appear to be 80 Plus Certified. Here's a review of another Linkworld product (LPSW) by JonnyGuru....it got a score of 0.5/10. http://www.jonnyguru.com/modules.php?name=NDReviews&op=...

It's likely that the LPK230-450 is over rated for wattage. I would definitely upgrade the PS if you are planning to do any system upgrades.

It means the psu cannot deliver the advertised power.

The model number indicates it is a Linkworld 450 watt power supply. Linkworld power supplies are very bad.

I maintain the PSU Lemon List:

Scroll down to the Linkworld section and you will see a brief summary of the problems and issues. You'll also find a link to the technical review that discovered the problems.
