Is the salesmen telling the truth?

[latiosx]

Well im trying to get a gtx770 into my system, salesmen recommend me to buy at least 700W gold rated power supply. im not convinced, according to nvdia webpage, gtx 770 required minimum wattage of 600W, also i have calculated the system(including little future upgrades), it shows me that i will need about 430W, i know it is better to have about 100-200W more than what the wattage calculator shows. The question is, should i go 700W gold rated or 600W bronze rated PSU. higher wattage definitely is better, but is it necessary?

P/S :i cant expand my budget any bigger 

 

 

here is my build,

CPU: i5 4670

GPU: msi gtx 770 twin frozer 2 gb

HD: 1TB HDD WesternDigital

SSD: 1 unit(not buying now due to budget)

RAM: 2 stick kingston 4gb hyperX

Casing: K820 cooler master 
FANS: total 3
Motherboard:G1sniper B5 gigabyte or MSI b85-G43
note: not planning to overclock cpu, adding sound card, network card, raid card, DVD rom or any other device in future.

500w would be enough. 600w is plenty.

I use 600W and had no problems whatsoever.

If he's thinking you might add 2 GTX770's in SLI, then he's covering you for the future. Otherwise 500w should be ample enough to run that hardware, 600w just in case you add say 3 more hard drives and a cpu radiator cooler or something.

[Paralectic]

A 500watts PSU would be enough.

[Moosie]

You're more than fine with 600w. As ZetZet said, you could get by with a good 500w.

[Maxibonbits]

600W is enough, especially since you won't be overclocking. However as a salesman recommending a 700W PSU is perfectly fine in my opinion.

[Stampkonijn]

A friend of mine has a 770 and uses a 550W Gold PSU. It works just fine.

yeah ... like anyone of that "get a 800Watt rated PSU" will listen to him anyway ...

Thanks for the information, it really helps.

450 is probably enough, look at me!

 

you should be golden with what you got.
