{Question} Larger PSU than components need

post #1 of 17
Thread Starter 
If I have plans to upgrade my rig down the line, can I go with a PSU that is nearly 200W more than my parts require?

For example, If I run a single gtx560 for now and then plan to upgrade to SLI and some sort of cooling in the future, can I get a larger PSU now so I won't have to repurchase further down the road?

absolutly. HOWEVER, 200w additional might be cutting it when you do eventually go sli.

another factor is though, you dont want to get anything to insane as im pretty sure power supplies run most efficiently at ~ 75% usage. ie dont get a 1200w for a system that needs 400w.

Hopefully Ph will come in here and tell it like it is

Yes, but don't buy extra watts you won't ever use, for example, a quality 650w is perfect for gtx560 sli.

There is no issue with putting to much power in, other than wasting $ on more PSU than you need. You could put 2x 1200Gigaherts power supplies in and it would run fine. No better than a decent one of the right size but fine none the less.

You can buy as big of a PSU as you want, but if you tell us what you plan to accomplish in the future we can probably make a fairly accurate estimation of what you should buy.

A good 650W unit will be perfect for you.

There is a great deal going on for the Antec TPN 750..I would pick that up for future proofing and a great deal.

I was either going to go with a HX650 corsair, X650 Seasonic, or an AX750 corsair. I would go with the HX750 but it doesn't fit in the case I'm getting.

You could go with any of those and be successful but the Antec unit that is on sale is a very high quality unit and it cheaper than all 3 of the units you listed while being a more powerful unit at the same time '

I would look into it and see if it will fit your case.

And if quality is worrying you on the unit, it is a re branded Seasonic
