Should I get a new PSU?

Seacoast
 Share

Hello, 

 

I'm starting an upgrade to my system and starting with moving it to a new case and adding a custom water cool loop. 

 

I have a Corsair HX750W, the old professional series. It works fine and I have not had any issues with it. It's been in my current set up for 5 years.

 

Would you suggest buying a new one or should it be fine to wait to upgrade it till later down the line. 

 

I'm not pushing my system remotely close to the 750 watt range. I have a i5 on a z77 atx board and a single GTX 760 GPU my case I'm switching to will not have any RGB, and I'm planning on using the EK S240 water cooling loop.

It should be fine. I wouldn't get a new PSU, it'd be a waste of money.

Yeah, you certainly won't be pushing that to its limit so it should be alright until later down the line. I know some people with PSU's that have been going for 8, 9 or even 10 years because they either went overboard with their PSU early on or don't meet their max output at all under full load. I would say wait another year or two maximum and go from there :)

Yeah,  the only benefit to getting a new one would be getting cablemod cables, which I still can do except my 24 pin mobo hook up wont be the new nice cables.

Honestly, I wouldn't count that as a major concern as you could just get a 24 pin extension cable in the same colour that you'd have all the rest of your cables in :)

If it's doing fine, why bother? I mean it's still a good psu, and your setup is not maxing out the psu. You're on the sweet spot of efficiency curve I believe. Some custom made cables will be nice though, aha.

I didn't even think of cable extensions, that will make it look much cleaner in the meantime.

Not quite on the sweet spot. His setup pulls around 100w at idle and maybe 300w at load. I would assume that the efficiency @ 10% load on that thing is worse than bad. So it's actually costing him money to still use that PSU. Don't forget that a regular PC sits at idle/close to idle loads most of the time.

I found and used a PSU Calculator and this is what I came up with, Load Wattage 431W

PSU Calculator Part List

 

I used what I would have during the first step of the upgrade.

First rule of power consumption: never use calculators.

learn something new every day.  without knowing specifics i figured it would give a good rough estimate.

Well, yes and no.

 

Calculators from PSU manufacturers are biased, they want you to do what... ? Buy PSUs and a more expensive one so they overestimates by a ton. A rule of thumb is that you could take their guesstimates in half to get a number close to what you really need. PCPartPicker is OK-ish as they don't get any money from recommending you to buy more than you need.
