View Full Version : Will this power supply work with my pc?

19-12-2010, 04:46 PM
I'm currently using a 350w power supply.

I just looked in one of my spare pc boxed and found an unused 450w power supply. The Brand is L & C Technology. it says Total Output is 450w max. So i'm thinking this is 450w?

If so, is it safe for me to put it in my computer? as an upgrade?

It'll be better than 350w

Any particular reason to change from the One you have working Now ?

It will work, BUT it may also cause more trouble than its worth.
The PSU is one item you don't want to skimp on, a bad / cheap/ Budget PSU can blow the whole PC.

Just did a google search, and found several posts similar to This one (http://forums.techguy.org/reviews/644669-l-c-technology-psu.html).

Your choice, but if your current ones working, and no problems, dont fix what aint broke :D

Can't see why not. If your current one is working OK, can't see any advantage in changing it, though, unless you are planning on adding more power draining devices.

Also, no guarantee that the 'new' one is any better given the tendency of many manufacturers to exaggerate. The wattage rating is a very fuzzy/global parameter in any event.

isn't a bigger power supply better?

and also, it has more power imputs, which means (If i can find the correct ribbon) i can put a 3rd hard drive in.

Have you tried this other 450W PSU in the box its in to see if it does actually work?

If you're not approaching the peak draw of your current PSU, and it's decent quality, there is no benefit in upgrading.

NO. A decent brand is better.

And L&C are Craaaaaaaaaaaaaaaap.

Craaaaaaaaaaaaaaaap = Boom Boom, or unstable problems sooner or later :D

Only if it really is bigger. Cheap generic PSU makers have been known to exaggerate.

ALWAYS stick to quality PSUs only, forget any cheap nasty ones.

To be honest most crappy PSUs are "ok-ish" if you don't overload them. (which often causes them to go bang)

But they still use useless capacitors which will die fairly quickly, and they often don't have decent input protection.

Any strange thing going on with your mains power supply and they can go bang...

I have\have seen multiple failed Hyena (deer) PSUs and problems were always dead capacitors.

Not necessarily. What you need to compare are the current ratings for each voltage rail. I know of some 450w psus which have lower ratings on the 12v rail than some 350w ones.

As for brands, I've had an enermax fail after 8 years, but the psu that came with the case (icute) is still going strong... I guess this is a fluke, since I believe you do get what you pay for.
