400w branded or 450w NonBranded case PSU ?

YOthisisYO · Jan 20, 2017

I have two PSUs , specs of both are attached in this Thread (as Pictures) . I am thinking of buying a GTX 1060 3gb , Which PSU is most appropriate for the use ?

Both of those PSU's real wattage is much lower than described.
Both are not good.
Could you link the store?

EDIT: Oh, you already have them.. That's bad, better get a new one.

I thought CoolerMaster one 400w , is more than enough for a GTX 1060 3gb , I dont even overclock . Many Threads say 300w good psu is enough , Can you please explain what do you mean by "real wattage" ?

On that one it states it's real wattage is 327Watts. Otherwise you can calculate by multiplying the +5, +3.3 and +12 volt rails by their current, and then adding those together.
Wattage = Volts * amps.

The 1060 requires 300-400 watts.

The Coolermaster RS-400-PSAR-I3 was made by Solytech and is rated for a total draw of 350 watts (327 on label, 250 per cetification) .. Solytech is by no means considered a quality OEM but the other one I'd be afraid to plug in.

Also... multiplying all the amps and voltages on the label will greatly exceed the actual wattage capability of the unit.... those rails are individually rated for up to that much.... that doesn't mean the intake side can handle all of them at once. It even says that on the CM label.

Neither. Both are not suited for the purpose. Both are a disaster waiting to happen. Both have pitifully weak 12v outputs and on modern systems that is the most used rail. I highly doubt either one would reliable run a system with a 3Gb 1060.

Will they work with GTX 1050 2gb ( non ti ) ?

lakimens · Jan 20, 2017

They will work, but it's a dangerous risk.
A usual scenario with a bad PSU is, it dies and kills something on the way(Sends deadly power to it).
Worst-case secnario, it catches fire.While you're sleeping.

JackNaylorPE · Jan 20, 2017

While warnings of impending death risk are a bit exaggerated, I can't say it any better than this... nVidia requires a 400 watt PSU.... and that's a real 400 watts not "400 on the label but 327 for real" ... if you use less than that, you are running "at your own risk".

Switching to a lower powered card isn't really solving your problem. Even tho 327 is the stated capability of that CM PSU, since its an old PSU, due to capacitor aging, I doubt it can still deliver that wattage with spec.
