400W is only half the story, it depends on the certification (80+/BRONZE/SLIVER/GOLD), warranty, supplier (Best are Corsair/Antec/XFX/Seasonic). That just says if you have a 400W quality PSU.

Main thing besides wattage is the amps and voltage, what are they?

those cards require power, which 400W should be enough, but it need to have the right Amps and Voltage output also.

Depends on the exact PSU in question, not all 400W PSUs are made equal.

I would not suggest getting low cost Gigabyte PSUs, not very trustworthy in general.

It totally depends what ATX 400W. If it genuinely drives 400W you'll be fine. But many units outright lie about their rated wattage.

What's the make and model of your PSU?

hi i dont actually know how much amps my psu hav
but here are the details

switching power supply
model ATX 400w
ac input : Voltage 230V current 5A Frequency 50hz
dc output max: orange 3.3v and 18A ,Red +5, 18A , Yellow +12V , 20A, White -5v .05A,Blue +12V,03A,purple 5V,2A,grey P/G, OK
so will this be okay to run r7 250x/260x or do i need to change it plz rply??????

not always, Cheap PSU's do sometimes have low voltage and amp outputs, but most of the time it should be the same.

Yeah you do. That is a very much underpowered unit. Assuming it has a single 12v rail, you have about 240W of usable power, probably less because of capacitor ageing.

Get a new QUALITY unit.

Uhm voltage will remain constant, or at least within reason. As soon as voltage dips to low or peaks to high.(like 11v on 12v rail), then the computer would shut down completely.

Wattage and amperage on the other hand is a different story, but if low voltage was common, then those PSUs would never work correctly.

That's why nobody buys SHAW PSU's.

yes it will, though thermaltake are known to make low quality PSU's, that should be fine and is a better brand then Gigabyte for sure.

Yeah the Corsair is the better option for a cheap PSU, stay away from thermaltake too.

When you say "250x/260x", you mean 250x OR 260x right? Not both a 250x AND 260x?

Yes, it will certainly run one no problems at all.

I know. And I just noticed the first post where he said OR, so all is clear. It was just the consistency of use made me ask the question. Didn't want to take the risk of making a bad recommendation because of a / instead of an &. Always worth checking.
