Get new PSU or keep old one?

post #1 of 14
Thread Starter 
I just ordered sleeving and about to begin the process.

Here is the thing my power supply is almost over 3 years, it's topower 900w, I didn't have any problems with it... What's the life span of them? Power Bird Spec

Maybe it's time to replace it with new one? Something like seasonic ~750-900 w?


What do you guys think?

If all sounds fine then I wouldnt worry about replacing it, but if you have the money I would defo consider a seasonic one, chances are its not pushing out as much power as it did when new.

Will I see any difference on my electricity bill, with gold certified PSU?
I am just woried that I upgraded my system entirely except the PSU, and that I will have problems.

Is it for your sig rig? then I would honestly say you need a better psu, such as a Corsair 900w psu or a antec one! your elec bill will make no diffrence tbh maby a few pence a day but not as much as you might hope.

Yes it's for my sig rig! Why do you say that I need better PSU now?

I was thinking about Seasonic 850W

That's what I thought about electric bil... I was just wondering what was such a big deal of being gold certified

A decent 500W would actually cut it for your system.
Not a 900W.


And yes, there is a large difference between regular 80PLUS and 80PLUS Gold.

Quote from wiki on 80 plus:

"80 PLUS is an initiative to promote energy efficiency in computer power supply units (PSU). It certifies products that have more than 80% energy efficiency at 20%, 50% and 100% of rated load, and a power factor of 0.9 or greater at 100% load. That is, PSUs that waste 20% or less electric energy as heat at the specified load levels, thus reducing electricity use and bills compared to less efficient PSUs. Sometimes rebates are given for manufacturers who use 80 PLUS-certified PSUs."

Getting a gold rated power supply should cut down your electricity bill. smile.gif

That Seasonic 850w is a great PSU btw.

Your current PSU is of good quality, 900w modular 80+ certified. Why are you considering a new PSU?

If it aint broke, don't fix it. Would it not be funny if you bought a new PSU to replace this perfectly functioning one only to have the new one blow and take out some components? I think not. So the saying stands, if it aint broke, don't fix it. tongue.gif

PS> About the power bills. If your system uses 500w and you efficiency is at 80% then your wasting a max of 40w right? I doubt that will cause much more of a power bill, considering the differences in GPU power rates, 40w or less is pretty insignificant in costs. So again, if your current PSU is cutting it, and a newer PSU will do little to nothing for your power bill, why spend $200 (like the PSU you linked) for an upgrade you don't need? $200 can add a nice SSD, upgrade your GPU, or to go towards a future build. Stick the $200 in the bank, you'll be much happier.

yeah now that I've seen the specs I would get that, never seen it before

The legitimate reviews show it to be an excellent PSU. You probably wouldn't save enough on your electric bill to cover the cost of replacing it. I would stick with it until it dies then replace it. Since it isn't being overly taxed by your current system that probably won't be for a few years with any luck at all.
